The Trailer Lock System is designed for installation directly in front of the loading dock. The electric hydraulic system captures the ICC bar on the back of semi-trailers. To ensure maximum safety the unit comes standard with an accumulator that allows the lock to follow the trailer up and down as it is loaded/unloaded. A beeper and flashing light warns the operator if the lock does not engage the trailer properly. A visual indication of the restraint's status is shown at all times by the traffic light outside and the control panel inside. It comes standard with light package, control panel and three (3) large visual signs. Draw pull shear strength is 22,500 lbs per foot. Pre-drilled holes included for wall or ground mounting.
