Hild was removing the last bolts from the counterweight while standing on the back step of a service truck when the counterweight fell and struck him. The accident occurred because the contractor did not: 1) provide task training on disassembling major components on a hydraulic excavator, and 2) block the equipment against hazardous motion.
