SP load cells used for Belgian bridge repair
Four 150t capacity Straightpoint (SP) compression load cells from Lifting Gear Hire (LGH) have been used to weigh a Belgium bridge that had been removed for repair by Hye after a canal boat collision.
The impact of the collision shifted the roadway section of the bascule bridge 5-6m out of line on one side, while the mechanism that raises and lowers the two halves of the bridge was also damaged. Before and after an important phase of the bridge’s restoration, the wireless load cells were positioned under four supporting points of the structure and fed data, capturing individual and collective readings.
Davy Kraft, sales engineer at LGH Belgium, said: “The software is user-friendly and enabled us to give the report to the customer effectively in real time. The system recorded the weight on each individual load cell, total weight, and centre of gravity, and displayed it in a neat HTML report.”
Mr Kraft explained that there was no necessity to measure centre of gravity, but the information was readily available.
SP’s compression load cells boast a wireless range of 700m or 2,300 ft. The load cells and software commonly combine to verify the centre of gravity and weight of large and heavy objects that may not be evenly proportioned. Mr Kraft and his team also utilised 100t capacity Hi-Force hydraulic jacks to raise the bridge and lower it onto the load cells.
Repair work continues on the bridge, which crosses the Brussels-Scheldt sea canal at Humbeek-Sas in Grimbergen, north of Brussels.
