As a mobile crawler crane was being dismantled, some welds on a homemade adapter failed. Side-loading had occurred when two unsecured pins (no cotter pins) backed off, allowing the plates on the adapter to spread. The steel "bridle" fell onto the house of the crane, deflected to the back of the crane, then fell to the ground. One worker became entangled in the cable and was pulled down onto the detached 15-ton counterweight and then to the ground about 12 feet below.

An I-beam weighing 14.5 tons was rigged at grade level using two separate synthetic slings choked to the I-beam. Abrasion protectors were used. The slings were attached to the load hook of the tower crane, and the I-beam was raised to an adjacent roof to control and place the beam with a tag line. The choker slings were then rigged at different lengths so that the lower part of the beam could be seated on the angled plate on top of the column. As the workers on the roof were receiving the load, the longer choker sling started to slip. This sling eventually severed, and the end of the I-beam fell onto the roof. The crane operator was able to lower the other end of the I-beam onto the roof.
