An employee backed a tractor trailer into the delivery area of a customer store to unload soft drinks. The unloading area has a hydraulic lift platform with a lift gate on two sides because the receiving floor is at ground level, which is 4 feet lower than the trailer bed. The controls for the platform ride up and down with the platform and are operated by delivery truck drivers. The employee had finished unloading the product and was preparing to leave. He needed to slightly lower the platform to close the door on the back of his truck. He stood on an 18-inch-wide ledge and fell off. His jacket got caught on the control, which triggered the lift, and he was caught in a pinch point between the lift gate on the platform and the control panel. He suffered a puncture wound in the left groin, a broken pelvis, and a tear in his aorta.
