We have received a report of a 500 tonne All Terrain crane overturned this weekend in the UK.
The incident occurred at the premises of Aquatic Subsea on an industrial estate in Peterhead, Scotland. The crane's boom was fully elevated, with the heavier sections fully retracted, and the top three sections either fully or partially extended. The super lift system was also installed with the counterweight over one outrigger.
The crane had been brought in to load a heavy module, and overturned when the ground gave way under the outrigger beneath the counterweight. The super lift arm hit the ground stopping the machine’s movement abruptly. The dynamic/shock loading in the wrong direction to what the boom is designed for, caused one of the boom sections to buckle.
The crane is a relatively new Liebherr LTM 1500 owned by William Whyte of Aberdeenshire, Scotland. We have no further details at this stage but understand that no one was hurt in the incident.
