Client Requirement

The client wanted Unique Group to complete calibration testing of the safe load indicator after replacement of a faulty load pin on a crane.

Unique Solution Delivered

The client asked us to apply 360 tonnes. We used 4 water bags of 55 tonne combined with 2 water filled proof load bags of 35 tonne for the first tier, followed by 3 water bags of 35-tonne water bags on the second tier. In addition to these, we also used a 400t telemetry load link to monitor the load going into the bags.
