BroadWeigh Blue Telemetry User Manual

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 is 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.
