ABSTRACT:
A vehicle restraint for a truck loading dock includes an actuator that rides up with a carriage to sense that a truck's ICC bar is within a predetermined region before fully extending a restraining member to engage the bar. The carriage and restraining member are raised and lowered by a drive unit, such as a cable extending from a winch. The winch may be attached directly to the carriage, or optionally remotely mounted to the dock. One end of the cable connects to a spring that compensates for incidental vertical movement of the ICC bar caused by the truck being loaded or unloaded. Large downward movement of the ICC bar is accommodated by a clutch associated with the winch. For large upward movement, the winch automatically restarts to pull the carriage up to meet the new height of the bar. An optional ICC bar deflector mounted at the base of the dock, along side the carriage, wedges underneath an exceptionally low ICC bar as the truck backs into the dock. The deflector guides and lifts the low bar above the actuator to prevent premature and uncontrolled extension of the restraining member.
