Ceiling Brackets
Our intention with this planning guide is to offer architects, consulting
engineers and others a tool that can simplify the planning of effective
ceiling hoist systems.
Our goal is to ensure reliable, effective solutions for the benefit of all
parties.
Although we have made every effort to provide answers to the most frequently
asked questions, which experience has shown may arise when planning ceiling
hoist systems, other questions and problems will unavoidably arise.
We therefore offer professional assistance in the form of such services as:
- initial demand analyses carried out by Guldmann’s ergonomic specialists
- help with planning and calculations, call us or send us a sketch or AutoCAD drawing
- participation in planning meetings
- a visit to our demo-rooms where you can see and try out the functions of the products and test planning arrangements in practice
As a principal rule we provide service free of charge.
Guldmann’s installation and service departments have undoubtedly the most
experienced corps of quality conscious installers and service consultants.
This allows us to offer installation and, if required, subsequent operation of
both simple and highly complex systems at competitive prices.

Lifting disabled people
Security, safety and comfort. These are the key words when lifting a disabled
person. Both for the disabled person and for the carer, who must also
safeguard his or her health.
Guldmann’s activities have since 1980 been based on these three key words.
Today Guldmann specialises in technical aids for securely, safely and
comfortably lifting and moving disabled people. Constant product development
has resulted in the Guldmann’s ceiling hoist system – a comprehensive, unique
and cohesive system that is characterised by great flexibility.
Guldmann’s ceiling hoist system comprises a wide range of lifting and rail
modules that can be combined with different types of hoist and lifting sling.
A lifting sling is a textile belt that the disabled person is placed in when
being lifted. The individual components can be combined to create both simple
and highly complex systems.
A ceiling hoist system is extremely flexible and is designed to meet the
individual needs of the disabled. At the same time the system makes it
possible to adapt to the various architectural conditions and limitations that
must be taken into account when installing a hoist.
Guldmann’s ceiling hoist system has a simple, distinguished design and can be
discreetly incorporated into the user’s surroundings.
In order to gain the maximum benefit of a ceiling hoist system it is important
to take the system into consideration from the beginning when planning
accommodation for the disabled – whether this is a new building or a
conversion of existing premises.
Rail systems in general
A rail system comprises one or more rails, which are installed on the ceiling,
the wall or on freestanding uprigth support brackets.
The rail system is constructed in modules. This makes it easy to create
individual solutions and to adapt the system to existing buildings. The
modules are easy to handle during installation and transport. The flexible
modules also make the system suitable for recirculation.
Rail systems can be installed anywhere. Private homes, hospitals, nursing
homes, therapy clinics, riding centres and swimming pools are just some of the
places where a rail system can help to improve the working environment for
carers and heighten the quality of life for the disabled.
A ceiling hoist system takes up no floor space, makes little noise and is
always ready for use. The ceiling hoist itself runs in the rail system.
All Guldmann’s ceiling hoists lift with the help of a battery operated motor.
The hoist is equipped with a hanger to which the sling is secured. The rail
system that the hoist runs in can be:
- A room-covering system
- Single track
- A combination of the two systems
The hoist is manually controlled, or controlled with the help of a drive- motor.
SOLUTION TYPES
– Presentation of different ceiling hoist systems
The room-covering rail system
The room-covering rail system comprises two parallel rails installed on the
ceiling, the wall or on freestanding uprigth support brackets. A traverse rail
runs between the parallel rails. The hoist itself glides backwards and
forwards on the underside of the traverse rail in a travelling trolley, which
is equipped with wheels that run inside the rail. Horizontal movement is
smooth and comfortable for the user.
The room-covering system makes it possible to lift the disabled person to and
from any place in the room and is the optimum solution in rooms where many
lifts are carried out.
Installing a room-covering system saves space and provides an extremely high
degree of freedom. The bed, a wheelchair and the other furniture in the room
can be placed as desired and lifting can be carried out rapidly, easily and
comfortably both with regard to the carer and the disabled person.
In addition the planner has considerable freedom to design the rooms in the
building – both because the system saves space and because it offers
flexibility when lifting a person.
In some cases the parallel rails can be built into the ceiling so that only
the lower part of them is visible.
The single track rail system
In its basic form the single track rail system comprises a single rail in
which the ceiling hoist runs. The system can be extended with curves of
various angles..
The single track system is very suitable for moving people over longer
distances. Examples of this could be corridors, riding schools or swimming
pools.
Over and above this the single track system can be used in the same situations
and rooms as the room-covering system. But attention should be paid to the
fact that wheelchairs, beds and other aid facilities must be located directly
beneath the rail. This places limitations on the layout of the room due to the
location of the rail.
In some cases the rail can be built into the ceiling so that only the lower
part is visible.
Combination system
It is possible to combine the room-covering system with a single track rail
system in adjacent rooms with the help of a Combi-lock.
A safety lock is installed in the traverse rail in the room-covering system to
prevent the hoist from running out of the rail. A Combi-lock is installed in
the single track rail system. The Combi-lock locks the traverse rail to the
single track rail and at the same time releases the safety lock. The hoist can
then be run from one system to the other without problems.
The rail in the single track rail system must be installed at a right angle to
the parallel rails on the room-covering rail system.
The parallel rail in the room-covering system which is closest to the room
with the single track system must be installed some distance into the room to
provide space for the safety lock and the Combi-lock between the wall and the
rail.
Types of hoist
All Guldmann’s hoist types lift with the help of a batterydriven motor and
run in the rail system with the help of a travelling trolley, which is
manually controlled or controlled with the help of a motor.
GH3
GH3 ceiling hoist lifts with the help of a lifting hanger to which the sling
is attached. The hanger is raised or lowered from the hoist, which is
installed in the rail and can only be moved horizontally. Lifting capacity up
to 250 kg (550 lbs).
GH3+
Ceiling hoist similar to GH3, but with options like integrated scale, care
lift management and service monitoring system. The lifting speed is also
faster. Lifting capacity up to 350 kg (770 lbs). GH3 Twin
GH3 Twin is a heavy duty ceiling hoist with double lifting straps, which lifts
using a cross hanger or a horizontal lifter on which the sling is attached.
Lifting capacity up to 500 kg (1100 lbs). GH1
GH1 has a lifting capacity up to 205 kg (450 Lbs). GH1 is recharged when the
hand control is placed in the docking station. GH1 F
GH1 F is a flexible hoist which can rapidly and easily – with the least manual
handling – be transferred from one rail system to another in a specially
designed trans- port trolley. GH1 F has a lifting capacity up to 255 kg (560
Lbs.)
CONSIDERATIONS
– considerations in connection with integrating a ceiling hoist into a
building
Needs and function
When designing buildings for the disabled it is important for all parties
involved to clarify the following questions when choosing technical aids
facilities for lifting and moving people:
Who are the users?
It is an often overlooked fact that both disabled people and carers are users
of systems for moving people.
Where is the lifting requirement?
The bedroom?
The bathroom and toilet?
Guldmann recommends that daily working routines should be reviewed by a
working group comprising a carer, a therapist, technical staff, an architect
and a ceiling hoist consultant. This will make it possible to discover where
the lifting requirements in the building are and, on the basis of this, to
arrive at the best solution for all users.
Which lifting method is best in the specific situation?
A manual lifting?
A mobile hoist?
A ceiling hoist?
Although a ceiling hoist system will be the most functional solution in most
situations, other lifting methods can be more suitable in certain cases.
Which rail system should be chosen?
A room-covering system?
A single track system?
A combination?
Which type of ceiling hoist should be chosen?
GH3?
GH3+?
GH3Twin?
GH1?
GH1 F?
Which type of building is in question?
An existing building?
A renovated building?
A new building?
A ceiling hoist system can be adapted for use anywhere, but the possibilities
vary depending on whether a new or an existing building is in question.
REMEMBER
– the choice of a technical aid is decisive for:
What the working environment will be like for carers
What the user’s quality of life will be
How the entire area of the room can be utilised
How the carer’s time can be utilised
How money can be utilised
Guldmann can help to arrive at the optimum solution in each case.
Transition through a door opening
Once it has been established that there is a need to carry out lifts in
several rooms, a decision must be made as to how the disabled person will be
moved from room to room and from rail system to rail system. The door opening
can either be heightened so that the rail can be led directly through and the
hoist can be run from room to room without stopping. Or a Swing solution can
be chosen, where the original height of the door opening can be retained and
the disabled person be “swung” through the door opening. This can be carried
out with two GH3 hoists where the hanger is “swung” through the door opening.
Rail transition is the most functional solution both for the disabled person
and the carer. However, attention should be drawn to the fact that there are
certain limitations and problems in connection with a Swing solution.
|
---|---
Rail transition| The Swing solution
Transition through a door opening Ordinary door
Ordinary door
The door plate and the door opening are increased in height so that they reach
the lower edge of the rail.
Transition through a door opening Sliding door
Sliding door
As with the case of the ordinary door, the door plate and the door opening are
increased in height so that they reach the lower edge of the rail. The rail is
led through the frame.
The one-sided suspension of a sliding door means that the door can be closed
around the rail.
Transition through a door opening Ordinary door – opening for hoist
Ordinary door
– cutting a hole in the wall for the hoist
The hoist is run through an opening in the wall – allowing the original door
height to be maintained.
Remember to find out how wide the hole for the hoist should be.
Transition through a door opening GH3 Swing
In order to be able to use a GH3 Swing solution with transition through a door opening, ceiling height must be at least 2400 mm and the maximum thickness of the wall must be 110 mm.
Advantages of the GH3 Swing
- Saves the expense of heightening the door opening and door plate.
Disadvantages of the GH3 Swing
- Moving the disabled person from room to room is time consuming.
- The carer must be given special instructions in order to be able to carry out the move correctly.
- It is necessary to use two hoists – one in each room.
| 1. Bring the two hoist as close to each other as possible. Adjust the
height of the lifting hanger on B so that the transfer can be performed
without the user touching the floor during the transfer from one hoist to
another.
---|---
| 2. Take the free lifting strap from hoist A and secure it to the swing
adapter on the lifting hanger. In order to lower the free lifting strap on A a
slight pull must be applied to the strap.
| 3. Lower the lifting hanger using hoist B while lifting the strap on A to
perform the swing transfer. The transfer has been completed when there is no
load on the lifting strap on B.
| 4. Disconnect the lifting strap on hoist B from the lifting hanger and
raise the strap on B out of the way.
| 5. Move the lifting hanger from hoist A to operating height, and the
doorway transfer is complete.
Installing ceiling hoist systems
A ceiling hoist system can be installed on the ceiling, on the wall, or
with the help of uprigth support brackets. The method of installation should
be chosen on the basis of the specific conditions in each situation.
Ceiling
Ceiling installation can be carried out on:
- Concrete ceilings
- Wooden constructions (requires reinforcement between rafters)
- Roof cassettes
Wall
Wall installation can be carried out on:
- Brick walls
- Concrete walls
- Light walls such as wooden and plasterboard walls
Upright support bracket
Upright support brackets are used when:
- Ceiling or wall installation is inappropriate or difficult due to lack of strength or other installations in ceiling or on walls.
Electrical installations
The following components must be connected to the power supply when a
ceiling hoist system is installed:
- Transformer for charging of hoist
- The Combi-lock
- The switch track
- The turntable
PLANNING
– Scale drawings and assistance with planning
Rail types
There are three different types of GH3 rails: Rail A, B and C.
GH3 rail A is normally used in single-track systems, straight and with curves.
The overall height of the rails in a room-covering system can vary from 99 mm
for two GH3 rail A (traverse rail mounted between GH3 rail A parallel rails)
to 381 mm for two GH3 rail C (GH3 rail C parallel rails with underhanging GH3
rail C traverse rail).
The traverse rail can be mounted between the parallel rails, be underhanging
or be a combination of the two solutions.
Rail combinations in room-covering systems Intermediate suspension
A traverse rail mounted between the parallel rails is an aesthetically good
solution, as the rail is installed close to the ceiling and takes up a minimum
of space in the room.
A. Rail A traverse rail mounted between rail A parallel rails B. Rail B traverse rail mounted between rail B parallel rails C. Rail C traverse rail mounted between rail C parallel rails
Rail combinations in room-covering systems
Underhanging traverse rail (with parallel A rails)
An underhanging traverse rail is used
- When it is impossible to mount the traverse rail between the parallel rails, because lamps, smoke alarms or similar equipment have been installed on the ceiling.
- When the traverse and parallel rails cannot be of equal height.
D. Rail A parallel rails with underhanging rail A traverse rail
E. Rail A parallel rails with underhanging rail B traverse rail
F. Rail A parallel rails with underhanging rail C traverse rail

Underhanging traverse rail (with parallel B/C rails)
G. Rail B parallel rails with underhanging rail B traverse rail
H. Rail B parallel rails with underhanging rail C traverse rail
I. Rail C parallel rails with underhanging rail C traverse rail
Rail combinations in combined systems
Intermediate suspension/underhanging traverse rail
The rails can be cut to size so that room-covering and single track systems
can be combined, even though different rail types are used in the two systems.
L. Rail A parallel rails with underhanging Rail A traverse rail, to a
combination system M. Rail A/Rail B parallel rails with underhanging Rail
B traverse rail/intermediate suspension, cut-out for a combination system
This solution is the most frequently used of the combination solutions and,
thanks to the solution with intermediate suspension, it has a harmonious
appearance. In addition the height of the combined system can be minimised
with the help of a Rail A facing the combination side. N. Rail A parallel
rails with underhanging Rail B traverse rail cut-out for a combination

V. Rail B parallel rails with underhanging Rail C traverse rail cut-out for a combination system X. Rail C parallel rails with underhanging Rail C traverse rail cut-out for a combination system
Rail curves
Rail curves are used where it is necessary to change the direction of the rail
in a single rail system.
Rail curves are available in angles of 30°, 45°, 60° and 90°.
All the curves have a centre radius of 500 mm.
As a minimum three brackets must be used to mount all rail curves – one of the
brackets must always be placed in the centre of the curve.
Combinations of rail curves
There are many possible combinations of rail curves.
All standard curves end in a 500 mm straight rail.
The dimensions given are absolutely minimum dimensions.
Turntable
A turntable must be installed in places where two rails cross each other.
The turntable is electrically operated. The ceiling brackets must be installed
as close as possible to the turntable. Maximum distance from the turntable is
300 mm.
Switch track
Switch tracks are used where there is a need to lead the rail in several
directions. The switch track is operated electrically.
As a minimum a bracket must be mounted at each rail end of the switch track.
Combi-lock – max 250 kg/550 lbs
A Combi-lock is used to lock the rails together when two rail systems are
linked. The Combi-lock is always used together with two safety locks to
prevent the hoist running out of the rail.
The Combi-lock and the two safety locks cannot be installed in the door
opening due to insufficient space. In the room where the room-covering system
is installed, the parallel rail closest to the adjacent room with the single
track system, must be installed at a sufficient distance from the wall to
leave space for the two safety locks.
The Combi-lock is available with electric or manual operation. In new
buildings, for instance, the switch can be built into the wall.
When a room-covering system is linked to a single track system, the single
track system must be suspended in order for the two systems to be at the same
height.

K. Traverse rail
Double Combi-lock – max 250 kg/550 lbs
A double Combi-lock is used to lock the rails together when two room-
covering systems are linked. The double Combilock is always used together with
safety locks to prevent the hoist running out of the rail.
The two room-covering systems are joined by means of a A rail on which the
double Combi-lock is mounted. The double Combi-lock cannot be installed in the
door opening due to insufficient space. Therefore it is installed in one of
the two rooms with the room-covering systems.
The double Combi-lock is always electric. In new buildings, for instance, the
switch can be built into the wall.
When two room-covering systems are joined, the rail that locks them together
must be suspended in order for the two systems to be at the same height.

Combi-lock – max 350 kg/770 lbs
Single Combi-lock – 350 kg/770 lbs Double Combi-lock – 350 kg/770 lbs
Calculating door opening and door plate
The following measurements are valid for sliding door:
- In connection with a single rail system (A-rail) the height of the door plate is calculated as the height of the ceiling in mm minus 112 mm.
This example illustrates the most frequently used methods when linking rails
in two rooms. If other requirements arise in connection with a project,
Guldmann will be pleased to help find the best solution.
If a coping board is to be used to conceal a sliding door rail, this board
must hang at a maximum of 8 mm below the lowest edge of the hoist rail, as a
wider board could hinder the free passage of the hoist through the door
opening.
Building rails into ceilings
Single rail systems
Single rail systems can be built into the ceiling, so that only the lower edge
of the rail is visible by using the profile for suspended ceiling.
Room-covering systems
In a room-covering system it will be possible to build in the parallel rails
flush with the ceiling or to raise the ceiling 22 mm from lower edge of
parallel rails.
Parallel rail flushes with ceiling
Parallel rail with 22 mm raised ceiling
Rail covers
Inserting side cover on rails
The cover is placed in the top and bottom groove on the side of the rail.
The covers can have different colors, the standard colors are white and grey.
But other colors or patterns can be provided.

Installation Ceiling
GH ceiling bracket standard
Use: The GH ceiling bracket standard is used for single rail and room-
covering systems. The distance between the upper edge of the rail and the
ceiling must be 25 mm.
Installation: Depending on the underlying surface or/and the lifting
capasity, the GH ceiling bracket standard should be secured to the ceiling
with one or two fittings. The bracket can be used on concrete and wooden
ceilings. GH ceiling bracket lowered standard for straight rails and
rail curves
Use: The GH ceiling bracket lowered standard is used for single rail
systems or room-covering systems.
Installation: The GH ceiling bracket lowered standard should be secured
to the ceiling with two fittings.
GH ceiling bracket standard for Combi-lock
Use: The GH ceiling bracket standard is used together with the suspension
bracket when a Combi-lock is used in combination systems.
Installation: The GH ceiling bracket standard is mounted with 2 fixings
in the ceiling.
Installation Ceiling
GH ceiling bracket lowered rod
Use: The GH ceiling bracket lowered rod (with aluminium profile) is used
in connection with suspended ceiling constructions. The bracket is primarily
used in rooms with high ceilings in order to be able to install the rail
system beneath the suspended ceiling at an ordinary installation and users’
height.
Installation: The GH ceiling bracket lowered rod is joined by cutting the
aluminium tube to the required length.
Note: There is no limitation with regard to the length of the GH ceiling
bracket lowered rod. But in connection with longer lengths the bracket should
be anchored to the wall or ceiling with a stabilizing bracket to stabilize the
rail system and ensure that the construction is solid even with a long
suspension.
GH ceiling bracket slope lowered
Use: An adjustable GH ceiling bracket slope lowered (with aluminium profile)
is used in rooms with high, sloping ceilings. The bracket makes it possible to
install the rail system at an ordinary installation and users’ height.
Installation: An adjustable GH ceiling bracket slope lowered, is
connected by cutting the aluminium tube to the required length. The aluminium
tube is first mounted on the U profile of the bracket. The bracket is then
installed on the ceiling in the same way as with the other suspended ceiling
brackets – but the angle can be adjusted on this type.
Exception: Must not be used in systems with a maximum load over 200 kg
(440 lbs).
Installation
Ceiling – stabilisation
GH ceiling bracket straight lowered
Use: The GH ceiling bracket straight lowered (with aluminium profile) is
used in connection with suspended ceiling constructions. The bracket is
primarily used in rooms with high ceilings in order to be able to install the
rail system beneath the suspended ceiling at an ordinary installation and
users’ height.
Installation: The GH ceiling bracket straight lowered is joined by
cutting the aluminium tube to the required length.
Remember to allow for the space required by the upper and the lower ceiling
brackets.
Note: There is no limitation with regard to the length of the GH ceiling
bracket straight lowered. In connection with the bracket it could be necessary
to use a stabilizing bracket to stabilize the rail system and ensure that the
construction is stable.
GH stabilizer bracket for Combi-lock
Is installed between room-covering rail system and single track rail system to
stabilise connection of rails.
Installation
Ceiling – stabilisation
GH stabilizing bracket
Use: The GH stabilizing bracket is installed as a side support for a
suspended GH ceiling bracket in cases where the rail system has been lowered
considerably relative to the ceiling. Even in connection with long suspension
lengths this makes the construction very stable.
Installation: A holder is mounted around the aluminium tube on the GH
ceiling bracket. The aluminium tube on the stabilizing bracket is cut to
length relative to the distance to the wall or ceiling and secured to the
holder on the ceiling bracket.
Installation
Ceiling – reinforcement
Reinforcement
In cases where the ceiling construction consists of wooden rafters, it is
necessary to install a reinforcement between the rafters in order to be able
to install the ceiling bracket.
For reinforcement use timber minimum 4”x 4” – 100 x 100 mm, with appropriate
fittings of the type BMF 3224 – 100 x 90 mm.
It is important to fasten the fittings with nails in the marked holes only, as
illustrated, or else the timber may split.
Lower edge of reinforcement shall be level with lower edge of rafters.
Shutter boards must be mounted direct under the reinforcement.
When mounting the Guldmann ceiling brackets in wood, it is important first to
drill a hole with a 4 mm drill before fastening the bracket with screws.
Nail the fittings to the marked holes only.

Ceiling – reinforcement
Reinforcement, Combi-lock
In cases where the ceiling construction consists of wooden rafters, it is
necessary to install a reinforcement between the rafters in order to be able
to install the ceiling bracket.
For combination systems it is important that the reinforcement is executed in
such a way that any buckling of the system is aligned – i.e. fittings for
parallel rail and fittings for combi-lock must be fixed to the same
beam/reinforcement.
In the centre of the door opening fix timber 100 x 150 mm (4″x 6”) on the side
of timber 100 x 100 mm (4”x 4”) with 4 angle brackets with ribs of type BMF
99.
It is important to fasten the fittings with nails in the marked holes only, as
illustrated, or else the timber may split.
Lower edge of reinforcement shall be level with lower edge of rafters.
Shutter boards must be mounted direct under the reinforcement.
Nail the fittings to the marked holes only.

Installation
Wall
GH wall bracket end
Use: The GH wall bracket end is used to install all types of rail between
vertical surfaces. The bracket can be used, e.g. in connection with installing
room-covering rail systems in rooms where the ceiling is inaccessible or
sloping. The GH wall bracket can be installed on all types of wall – both
brick and concrete, lightweight concrete, wood and plasterboard. But the GH
wall bracket end must be combined with a GH plasterboard bracket on
plasterboard walls without wall reinforcement.
Installation: The GH wall bracket must be secured to the wall with two
fittings.
GH plasterboard bracket
Use:
The GH plasterboard bracket is used as an adapter for the GH wall bracket in
connection with installations on plasterboard walls or other types of light
wall. A GH plasterboard bracket provides the necessary high stability and
strength to install rail systems on plasterboard walls. But it is a
requirement that these are double plasterboard walls at least 24 mm thick.
Installation surface (WxH) 303×303 mm.
Installation: The GH plasterboard bracket can be secured direct to the
plasterboard wall with four Fischer HM 5×65 S.
The GH wall bracket end must then be secured to the two threaded rods on the
GH plasterboard bracket with 10 mm lock nuts.
Exception: Must not be used in systems with a maximum load over 200 kg
(440 lbs).
GH wall bracket side
Use: The GH wall bracket side, is used as side-hung brackets at the
parallel rails in a room-covering system.
The GH wall bracket can be installed on all types of wall – both brick and
concrete, lightweight concrete, wood and plasterboard. But the GH wall bracket
end must be combined with a GH plasterboard bracket on plasterboard walls
without wall reinforcement.
Installation: The GH wall bracket for side-hung rails must be secured to
the wall with two fittings.
Note: The GH wall bracket for side-hung rails can also be used as an end
bracket.
Installation
Wall – reinforcement
Mounting of brackets in plasterboard walls requires wall reinforcements.
Each reinforcement must consist of:
2 pcs of 21 mm plywood sheets of Finnish beech.
Height: 400 mm.
Width: distance between vertical steel latches according to Guldmann
layout for placing of rails.
The plywood sheets are mounted with 7 pcs of flat-headed screws 4×32 mm on
each of the vertical steel latches.
As standard the plywood sheets shall be placed as close to the ceiling as
possible.
Installation
Floor
GH upright support bracket
Use: The GH upright support bracket is used in rooms where it is impossible to
secure brackets to the ceiling or the wall. These could be rooms with
extensive window areas, for example.
The GH upright support bracket can be supplied with various types of adapter
that make it possible to lead studs around such obstacles as cable and
installation panels or skirting boards.
The GH upright support bracket and adapter can be used e.g. at institutions or
hospitals, where it is difficult to fasten brackets to the ceiling due to
various pipe systems.
Installation: The GH upright support bracket is installed on the floor,
but the brackets must also be fastened to the wall in order to guide them.
Can be mounted on single plasterboard.
Electrical installations
The transformer must be connected to the power supply when a ceiling hoist system is installed:
- Transformer for charging of hoist
- The Combi-lock
- The switch track
- The turntable

Location of transformer
The transformer must be connected to the power supply when a ceiling hoist system is installed:
In connection with single rail systems the power point should be located in the closest corner (2).
In connection with room-covering systems the transformer should be located in the corner with regard to accessibility and furnishings (1). Electrical installations
Combi-lock
-
The Combi-lock
(the linking rail between two rail systems)
A 110/220 V electrical point (a plug without a switch) must be used for the Combi-lock. The transformer should be plugged into the power point.
Where possible the power point should be installed on the ceiling – on a truss for example above a suspended ceiling, where applicable. If this is not possible the power point should be installed on the wall near the ceiling in the corner closest to the Combi-lock.
Hand control for the Combi-lock
When the hoist is run from one rail system to another the Combi-lock is activated with the help of a hand control. The hand control (illustration A) should be placed at an ordinary height next to the door opening.
The hand control for the Combi-lock can also be integrated into a wall switch (illustration B). A. Hand control for Combi-lock
B. It is possible to inte-grate the hand control for Combi-lock into a wall switch (1,5 module FUGA).

Switch tracks
A 110/220 V electric point (a plug without a switch) must be used for the switch tracks. The transformer should be plugged into the power point.
Where possible the power point should be installed on the ceiling – on a truss for example above a suspended ceiling, where applicable. If this is not possible the power point should be installed on the wall near the ceiling right next to the rail.
Hand control for the switch tracks
The same procedure should be carried out in connection with installing the hand control for the switch track as when installing a hand control for the Combi-lock, however, the former does not have a light diode. -
Turntable
A 110/220 V electric point (a plug without a switch) must be used for the turntable. The transformer should be plugged into the power point.
Where possible the power point should be installed on the ceiling – on a truss for example above a suspended ceiling, where applicable. If this is not possible the power point should be installed on the wall near the ceiling right next to the rail.
Hand control for the turntable
The same procedure should be carried out in connection with installing the hand control for the turntable as when installing a hand control for the Combi-lock, however, the former does not have a light diode. A. Hand control for switch track and turntable

Protection against electric shock
These precautions apply to installations made in Denmark.
Local requirements may differ.
Guldmann ceiling hoist and rail systems are manufactured and installed in
accordance with the rules on Electro-Medical Equipment IEC 60601-1.
Guldmann has a UL/DEMKO approval of its products which confirms that they meet
the requirements contained in IEC 60601-1.
This regulation defines how medical equipment must be classified and also how
it must be protected so that danger of electric shock does not arise when
handling the products.
Guldmann ceiling hoist and related rail system are classified as equipment in
Class I – High Voltage Regulation, Electro-Medical Equipment, Chapter 14.
Reference is made to Fig. 701A – Area Division 0 to 3.
Installation of the rail system is carried out with safety voltage –
designated SELV. The safety transformer with a nominal voltage of 33 V AC
voltage.
In accordance with the High Voltage Regulation, Chapter 701 – AREAS WITH
BATHTUBS OR SHOWERS
Chapter 701.4 Protection for safety reasons
When SELV is used (safety voltage), protection against direct contact must be
in place regardless of the size of the voltage, i.e. to min IP2X.
The geometry of the live rails meet the requirements for protection against
contact.
Chapter 701.413.1.6 Additional equalizer
Note
Metallic pipes and ducts (Guldmann aluminium rails) which are only found in
these four areas and are not conductive when in contact with earth or parts
outside the areas do not have to be connected to the equalizers.
Regarding installation of Guldmann rail systems in bathroom
environments
Guldmann power supply ( transformer) must not be in stalled and charging of
hoist must not be carried out in Areas 0, 1 and 2. Power supply and charging
area must be located outside Area 2, but hoist and rails may be used inside
the area.
If e.g. cleaning by hosing, the power supply and charging area must be located
completely separate from the area in which splashing with water may occur.
If the rail system is only installed in the bathroom and not in other rooms
outside the bathroom, the rails do not need grounding.
Grounding MUST be done if the rails continue outside the bathroom and the
lower edge of the rail is less than 3.0 m above the floor.
Excepted are:
Single rails hanging higher than 2.25 m above the floor and not continuing
into Area 0, 1 and 2.
For single rails the grounding may be located as required either in the
bathroom or in the adjacent room.
The parallel rails do not need to be grounded.
Note
These rules have been issued by the Electricity Council and form part of the
High Voltage Regulation.
There may be special local requirements for the installation of rail systems
in medical treatment areas.
Any special requirements carried out without the participation of Guldmann are
at the purchaser’s own risk.
