Two journeymen were tasked with operating the capstan and guiding the spider rope on the drum. The injured employee was operating the capstan controls and the second lineman was guiding the spider rope onto the drum utilizing a fiberglass rod. While pulling in the spider rope, it became taught when a roller failed causing the fiberglass rod to come out of the second lineman's hands and strike the capstan operator in the right hip. The injured employee suffered a right leg laceration and a fractured iliac bone requiring surgery and hospitalization.
