SPREADER BEAM OVERVIEW
The MGF S80 Spreader Beam is a modular system which can lift up to 80t and is
available in lengths from 1-14m with increments as small as 0.25m. The
capacities for various lengths are stated below. For smaller increments in
lengths please consult an MGF representative.
The system includes two End Attachments (D) which are bolted onto the end of
one or more strut extensions (E) to customise the length of the beam. The
system comes with Drop Links (B) on each end, which connect the Upper (A) and
Lower Shackles (C) to the
End Attachment (D). Endless round slings available for all lengths.

Table 2 – Components List
ASSEMBLY PROCEDURE
-
Check the ID details on each component to ensure the correct lengths are used.
-
Arrange the Extensions and End Attachments in the recommended configuration (see Table 1), ensuring that the longest extensions are central.
-
Check for debris between the flanges before connection to ensure the endplates sit perfectly flush with one another.
-
Bolt the components together using bolts, nuts & washers provided, 8no M20 x 80 bolts per connection. Tighten all bolts to a minimum torque of 240Nm, 2 threads minimum must be visible. Bolts should be re-tightened before every lifting operation.
-
Place the Drop Link inside the jaw of an End Attachment, ensuring that it is orientated so the larger hole is at the top.
-
Place a top sling onto the body of the upper shackle and put jaw of top shackle over the end attachment jaw.
-
Put top shackle pin through shackle, end attachment jaw and drop link, and repeat for other spreader beam end.
-
Attach free ends of top slings to crane hook.
-
Attach lower slings and shackles to lower holes of drop links and attach them to the load to be lifted.
-
The assembled spreader beam and lifting rig must be thoroughly checked by a competent person prior to lifting.
-
Recommended equipment for assembly: Torque wrench, podger spanner, ring spanner.
CRITICAL ASSEMBLY RULES -
A maximum of 4 extensions can be used in any configuration (plus one additional 0.25m).
-
STV (sling to vertical β) angle must be less than 45°.
-
The lower slings cannot be rigged at more than a 6° angle.
-
Position the longest strut in the centre of the beam.
-
Sling angle is critical for safe use of spreader beams.
-
The rigger must ensure there is clearance between sling end and End Attachment (see Figure 5).
-
Forsling to vertical angles between 30° to 45°, either use the 45° capacity or consult an MGF representative for an accurate load capacity.
SAFE USE WARNINGS
BEFORE OPERATIVES USE THE EQUIPMENT, THEY SHOULD READ AND UNDERSTAND THESE WARNINGS.
WHEN MOVING OR POSITIONING LONG EXTENSIONS OR ASSEMBLIES USE TAG LINES TO
CONTROL MOVEMENT
LOAD MUST BE LIFTED THROUGH THE DROP LINKS, NEVER
HANG LOADS FROM SPREADER BEAMS, HANDLING POINTS OR FLANGES AS THE SPREADER
BEAMS ARE DESIGNED FOR AXIAL COMPRESSION ONLY
THE EQUIPMENT MUST BE USED IN ACCORDANCE WITH THE PROCEDURES FROM ‘LIFTING
OPERATIONS AND LIFTING EQUIPMENT REGULATIONS 1998’ (LOLER)
OPERATIVES USING THIS SYSTEM SHOULD BE SUITABLY TRAINED, COMPETENT AND HAVE A
CLEAR UNDERSTANDING OF SAFE SLINGING PROCEDURES
IT IS CRITICAL THAT THE LENGTH AND CAPACITY OF THE SLINGS AND END FITTINGS
(PARTICULARLY TOP SLING) ARE SUITABLE FOR THE WLL BASED ON THE ANGLE SHOWN IN
TABLE 1
DO NOT EXCEED STATED WLL FOR EACH PARTICULAR SPAN AND SLING ANGLE SHOWN
IN TABLE 1
DO NOT RIG THE LOWER SLINGS MORE THAN 6 DEGREES FROM VERTICAL
INDIVIDUAL COMPONENTS CAN BE HEAVY AND EXTREME CARE MUST BE TAKEN IF MANUAL
HANDLING
INDIVIDUAL SPREADER BEAM EXTENSIONS INCLUDE LIFTING POINTS FOR SAFE HANDLING
(SEE IMAGE BELOW), IT IS CRITICAL THAT THESE ARE NOT USED TO SUSPEND ANY LOAD
OTHER THAN THE SELF-WEIGHT OF THE BEAMS. THEY ARE INDIVIDUALLY RATED TO
1000KG. THE HANDLING POINT ON THE END ATTACHMENT
(FIGURE 4) SHOULD BE USED FOR HANDLING THAT COMPONENT ONLY, THEY ARE RATED AT
200KG.
PRE-LIFT CHECKS
Before lifting there are several checks which should be done:
- Must ensure that there is suitable clearance between the equipment used to connect to the shackles and the end attachment.
- Must ensure that the drop link is free to rotate before use.
- Must ensure that the slings are not twisted or tangled.
- Keep the loaded spreader beam clear of obstacles – any contact could cause unsafe release of load or beam failure.
- Ensure the smaller shackles are attached to the bottom of the drop link.
- Ensure that the top sling lengths are suitable, and the beam does not tilt.
- the centre of gravity of the object being lifted is positioned underneath the.
- Each component needs to be checked prior to each lift.
- Carry out a visual alignment check for each assembly to ensure straightness without
- Prior to first use of a new assembly, carry out a trial lift just above ground level to ensure that straightness is maintained under its own self-weight.
RECOMMENDED TOP SLING TYPE
Textile slings, wire rope slings with soft eyes and chain slings with small
end fittings. If thimble eyes are used with wire rope then sling angle must be
less than 30 degrees.
Ensure that attachment allows adequate clearance as shown in Figure 5, a
longer sling will give greater clearance.
IT IS THE HIRER’S RESPONSIBILITY TO INSPECT THE BEAMS AND ALL FITTINGS PRIOR
TO ANY LIFTING OPERATIONS BEING UNDERTAKEN.
CONSULT AN MGF REPRESENTATIVE BEFORE LIFTING IF THERE IS ANY DOUBT OVER THE
QUALITY OF THE EQUIPMENT OR IF YOU ARE UNSURE ABOUT ANY ASPECT OF THESE RULES.
EQUIPMENT TO BE USED IN ACCORDANCE WITH MGF’S TERMS AND CONDITIONS OF HIRE.
ALL OPERATIONS MUST BE CARRIED OUT TO APPROVED METHOD STATEMENTS AND RISK
ASSESSMENTS.
