An employee was picking up a man lift from a job site. He was operating the lift inside the man basket and driving it up onto his truck. About halfway up the truck's ramp, the lift lost traction, slid off the ramp, and tipped over. The employee was tied off inside the basket and the fall was approximately 3 to 4 feet to the pavement. He suffered a fractured left femur and dislocated right shoulder, requiring hospitalization and surgery.
