Investigation Summary

Workers were assembling a Manitowoc 4100W tower crane on the paved surface of an intersection. The workers were preparing to pin the boom cap to a 42 foot insert when the cribbing apparently gave way, allowing the boom cap to fall on Employee #1. He sustained a complex scalp laceration; a left first rib fracture; left scapular and back contusions and abrasion; left anterior pneumothorax and associated pulmonary contusion; L-1 compression fracture; complex pelvic fracture; hematuria, traumatic, presumably secondary to pelvic fracture and bladder contusion; comminuted right intratrochanteric femur fracture; and multiple contusions and abrasions.
