A CRANE OPERATOR was crushed to death on site at Royal Liverpool University Hospital last Sunday when part of his mobile rig collapsed during a routine operation to extend the crane's jib .
The Health & Safety Executive is carrying out an investigation, but it is understood the accident happened as two boom sections weighing 2.4t and 1.6t fell as pins were removed to add an extra section to the crane's telescopic boom.
The 27 year old operator, Darren Crawshaw, was struck as one of the lattice structures crashed to the ground.
A doctor from the Liverpool hospital's casualty department assisted the man at the scene but he died from multiple chest and abdominal crush injuries soon afterwards.
Crane hire company Ainscough had been using the 250t Demag AC755 mobile telescopic crane to lift telecommunications equipment from a ground level car park to the roof of a 12 storey hospital building.
The crane had completed a series of lifts working on its main boom with a fixed fly jib extension. But the boom had to be extended to make a lift from 55m to place a control unit on top of a just erected steel frame.
The collapse came during the operation to add an extra 6m lattice section of fixed fly jib to the tip of the telescopic boom to allow the crane to reach up and over the hospital roof. Another crane was being used to dismantle the existing fixed fly jib configuration.
