The Dock Barricade represents the next generation of innovative loading dock safety systems. The electric/hydraulic power unit provides quick and effortless operation. It can stop a four thousand (4,000) pound loaded truck at four (4) miles per hour. It is electronically operated and consists of an electrical bumper-style safety stop circuit to sense obstructions when lowering. Installation is simple, anchor the unit to the floor, mount the control on the wall and plug in.
