Vehicle restraint with security device

摘要

A vehicle restraint for preventing movement of a vehicle from a parked position has a frame mountable at a loading dock to position a vehicle restraint mechanism operably coupled to the frame. The vehicle restraint mechanism has a restraining member with at least one hook movable between a lower inoperative position where said restraining member is out of contact with a vehicle to be restrained and an upper operative position where the restraining member contacts said vehicle and prevents movement from a parked position. A source of power, such as an actuator moves the restraining member upward to the operative position by having linkage coupling the source of power to the restraining member. A resilient member is coupled to the linkage and biases the restraining member into engagement with the vehicle. A security member is movable from a stored position to a blocking position preventing movement of the linkage in one direction thereby preventing the restraining member from lowering into the inoperative position and a spring member biases the security member into engagement with the linkage to prevent downward movement of the restraining member.
