Employee killed when struck by falling cable
Investigation abstract
Employee #1 and coworkers were using a 40-ton hydraulic crane to disassemble a 1 00-ton P and H crawler crane prior to moving it away from the work site. To inst all the counterweight on the crane, the counterweight had to be jiggled or wobbl ed so the mounting pins could be inserted. When they had installed three of the mounting pins, the weld holding the two-blocking device to one end of the suppor t cable broke. The two-block swung free, and the other support cable, which was looped over the pin of the boom pulley, slipped free of the pulley pin. This cab le fell 30 feet and struck Employee #1 on the back of the head, killing him. Emp loyee #1 was not wearing a hard hat at the time.
