Lampson Crane Overload

02/8/93

Overload Crane Queensland Australia 1993 (1)

The cranes are owned by Lampson, however, Lampson personnel had no involvement in the lift.

What made the M4100WS2 tip? The M4600WS5 and M4100 lifted the load, no problem. They then tracked sideways. During the tracking, the site personnel noticed the M4600’s counterweight was going to hit a steel bollard (post concreted into the ground). They kept tracking! Then they slewed the M4600 to the operator’s right, in effect pulling the load away from the M4100. They kept this going, thinking that they were almost there.

From reports, they then decided it was not going to make it and slewed the M4600 back (whoops), in doing so, it allowed the load to swing into the M4100’s boom as its tracks sat back down.

In any case, good planning would have identified the bollard before any crane work began. PREVENTABLE right?
