On 10/23/2018, at 2:00 PM, an employee was unloading an 80-foot boom from a trailer. The ramp from the trailer was not lowered at the time. He attempted to stop the lift, but the wheels were already at the edge of the trailer, and the momentum of the boom caused the back two wheels to slide off the trailer. When the wheels hit the ground, the boom had a catapult effect that threw the employee up onto the controls. His foot was still in the accelerator shroud, and his body momentum in combination with his foot being held by the shroud caused the tibia and fibula in his lower right leg to break. When the safety harness lanyard engaged and pulled him back into the basket, he landed on his broken leg, causing the bones to break through his skin.
