Introduction / Overview
Broadweigh Bluetooth range provides access to quality measurements on a mobile platform such as a phone or tablet. The delivery mechanism is Bluetooth Smart which utilizes the flexibility and availability of Bluetooth receivers while maintaining the low power requirements of embedded systems. Broadweigh Bluetooth is built upon two complementary principles of Bluetooth Smart, broadcast advertising data which enables users to deliver the same data to multiple receivers and low power paired connections which can be used in a point-to-point connection for configuration.

Safe Use
Designed to aid rigging professionals on a daily basis, the Broadweigh wireless load cell shackles offer simple, real-time, effective, and accurate load monitoring. It allows users to know the precise loads on any given rigging point, guy wire, or hoist in a rigging system. his valuable data enables the rigger to safely distribute weight for indeterminate loads, roof structures, and mother-grids as well as indicate alarms to avoid overload situations. The Broadweigh Shackle is a safety bow shackle with load pin and integrated electronics which features the following:
-
Available in 3.25 tonne WLL
-
Up to 90 m line of sight wireless transmission range
-
IP67
-
5:1 safety factor
-
Low rigging profile of 130 mm
-
10-month battery life at transmission 1 per second
-
Accuracy of ±1% of current load or 25 kg, whichever is the greater value (When using original bobbin. There may be a reduction in accuracy of these are wrapped.) Shackles must be correctly selected for the specific application required. As well as safe working load, physical size and fitment with other components need to be considered.
The shackle pin and bow are calibrated and load tested together. It is therefore essential for the accuracy of the system that the following information is adhered to: -
Each pin and bow must be kept as a pair and not interchanged. The bow is marked with the ID of the pin it is associated with as shown.
-
The pin must be aligned in the same orientation with the bow as it was when calibrated.
-
The Broadweigh shackle is designed to only fit together in one orientation, the anti-rotational bracket will only fit around the bow shackle on the side with CE marking. This is the opposite side to the ID marking.
-
The shackle must be used in conjunction with a bobbin, nut, and retaining clip as shown:
Any out of alignment, side, or twist loading will affect the readings given as well as load the shackle in a way that it was not designed for.
If using the shackle as part of a bridle, remember that the load in the legs of the bridle will increase with the angle. If the Broadweigh shackle pin is not connected to that part of the leg then it will not register this increase.
No part of the shackle, pin, bobbin should be modified by welding, grinding,
or similar.
Always ensure that the load is stable.
The allowable operating temperature range is -20°C to +50°C.
The working load limit (WLL) of Broadweigh shackles assumes the absence of exceptionally hazardous conditions. These include offshore activities, lifting of persons, and lifting of potentially dangerous loads such as molten metals. In such cases, the degree of hazard should be assessed by a competent person and the safe working load (SWL) reduced accordingly from the working load limit.
Please remember that Broadweigh does not give advice as to how the data from
Broadweigh shackles are used. All lifting operations are different and must be
supervised by suitably qualified and experienced riggers. It is the user’s
responsibility to ensure conformity with local regulations.
Broadweigh is not designed to be used as part of a safety-critical control
system. If it is required for one then the integrator would need to fully
assess its suitability.
Broadweigh shackle assemblies are subjected to a 150 % proof load (static test
coefficient of 1.5) before being calibrated.
Inspection and Maintenance
As with all rigging equipment, Broadweigh Bluetooth shackles should be
inspected before and after every use, ensuring that all the components are
present and correct (bow, pin, bobbin, nut, and r clip) and the serial numbers
match. All load-bearing components must be free from cuts, nicks, cracks,
gouges, or excessive wear and distortion.
Any damaged Broadweigh shackles or components must be taken out of service and
returned to your dealer to arrange refurbishment or scrapping. If you attempt
to replace or swap any load-bearing parts yourself the unit’s calibration will
be void.
It is also important before every use to check that all the settings are as
expected. The most safety-critical settings to check are that the system zero
and the units are correctly set (see the relevant sections in the manual). If
these have been unknowingly changed you could end up with unexpected and
misleading readings.
Before moving system zero or checking any readings please ensure that the
shackle’s temperature has stabilized. When moved from different temperatures
it can take up to an hour to reach the local ambient temperature. Once it has
done so, the readings can accurately be checked.
Always remember that damage to the shackle or its calibration can happen at
any time. If you need to move the system zero significantly then further
investigation is required. This could take the form of a thorough examination
and calibration check with a known load. Records should be kept of any
calibration check so that you can see any movement over time. If the readings
are out by more than 1% or 25 kg or you have to zero out more than 50 kg,
please return to your dealer to arrange recalibration.
These measures should be used in conjunction with your own thorough
examination routine at the same intervals you have set for normal shackles.
This will vary due to local regulations but should not be less than every 6
months. Records of all thorough examinations should be kept.
We would recommend checking your shackle’s output with a known load at least
once a year and a return to the factory for a calibration check every two
years.
There are very few maintenance requirements. The Broadweigh shackles,
TwistLinks, and battery enclosures need to be kept clean, threads clear of
debris, and protected from corrosion.
Do not overtighten screws when replacing batteries. Damage caused by
overtightening is not covered under the manufacturer’s warranty.
Remove the batteries if being stored for an extended period. Leaking batteries
can damage the circuitry and pin.
Pre Use Checks
Before rigging, check the shackles all work. Remove cover and insert 2 x AA
batteries, observing polarity and ensuring that there are no foreign objects
in the compartment. The LED will immediately start flashing to show that it is
transmitting (the factory default speed is once per second). Make sure that
the shackles all appear on the project dashboard on your phone or tablet. (See
below for setting up a project) Pre-use checklist
o Shackles power up
o Shackles talk to phone or tablet
o Data tags match as expected
o Pins and bows match
o Anti-rotation brackets are correctly positioned
o Bobbins are in place
o R-clips are in place
o Shackles’ data tags and rig location are noted
o All load-bearing components must be free from cuts, nicks, cracks, gouges,
or excessive wear and distortion
It is a good idea to note down all the shackles’ data tags and where they are
located within the rigging plot. This is crucial for identifying which loads
are being measured and where.
Getting Started with the App
https://play.google.com/store/apps/details?id=com.broadweigh.b24
This app requires access to the Bluetooth Services which are part of Location Services so the user may need to grant permission for the app to access Location even though the app does not use any location data.
Troubleshooting
Some or all of the tiles in the Dashboard are greyed out and are not receiving
data and/or ‘Timeout’ is shown at the bottom of the screen.
Is the View PIN set correctly?
For the receiving device to see any data from any shackles it must have the
view PIN set the same as the shackles. This is set when configuring the
project, see above.
Is someone else configuring one of your shackles?
When in configuration mode, the shackle changes its transmission mode. This
means that it cannot be detected by any other device. Once the configuration
has been completed the shackle should appear again.
The tiles are not refreshing as often as expected.
Are there obstructions/ is the distance too great?
As the radio is less powerful than the Broadweigh original it is more
susceptible to obstructions. Try moving closer or just to another position.
Is there a lot of other radio traffic in the area?
One of the bonuses of Bluetooth is the availability of the technology.
However, it can also mean that when there are a lot of people in a confined
area the 2.4 GHz can get saturated. If you expect to be in a high-traffic
area, do not rely on getting regular updates. It is likely (dependant on your
receiving device) that some data will still get through intermittently.
Unexpected values displayed.
Has the tile or inputs been tared?
Come out of the project and then back into it, this will clear any zero that
has been applied.
Has an unnecessary or incorrect function been used?
Check the expression field of the tile. Remember that any multiplication will
be applied before a unit conversion.
Are the units are as expected?
The settings in the tiles allow unit conversion. Make sure that they are set
as required.
