An employee was working with another crane operator to move a crane. The employee had taken in the outriggers on his side and was moving one of the pads to a designated spot on the crane. He was walking around to the other side of the crane where the other operator was still putting the outriggers up. He slipped in the muddy conditions and put his left hand out to catch himself. His hand landed on the outrigger being brought in, crushing his ring and middle finger resulting in the amputation of both fingers.
