Worker suffered traumatic and permanent disabling injuries when his right ankle and foot were trapped and crushed while using the defendants' hydraulic lift gate. Plaintiff was standing on the lift gate and controlling the upward movement of the lift with the accessible control bar. When the piece of equipment he was loading into the truck moved, he released the control bar to stabilize it. After the bar was released, however, the lift continued its upward movement, trapping the worker's foot between the lift and the rear sill of the truck. The "conventional" hydraulic lift gate was designed and manufactured by defendant W, and installed, maintained and serviced by defendant L, Inc. The worker was injured as the direct and proximate result of the defendants' negligence and breaches of warranty, including, among other defects, the failure by the defendants to provide adequate safety devices and warnings to prevent such foreseeable tragedies.
