The crane owned by Master Projects was reported to be working out of level and the boom subjected to serious side loads.

As a result the boom was literally ripped sideways from its pivot point.

Close up photographs of the boom base and pivot area indicate a severe overloading which ripped thick steel plate, while the forged lift cylinder pivot was sheared in two.
