Abstract
A vehicle restraint to be mounted on a loading dock for preventing accidental movement of a vehicle, such as a truck, from the dock during a loading operation. A hydraulic cylinder unit is connected through a flexible member, such as a chain, to a hook-like restraining member. By extending and retracting the hydraulic cylinder unit, the restraining member can be moved between the lower storage position and an upper operative position where it engages the ICC bar of the truck. In addition, a resilient member, such as a gas spring, is operably connected to the chain at a location between the attachment of the hydraulic cylinder to the chain and the attachment of the chain to the restraining member. The resilient nature of the gas spring will permit limited movement of the chain to accommodate vertical float of the ICC bar and truck bed during a loading operation. The restraining member includes an outer section or tip that can be moved inwardly toward the dock by a separate fluid cylinder to snub the tip against the ICC bar to prevent fore and aft rocking of the truck during the loading operation.
