Abstract: A system for restraining a vehicle, such as a truck having a pair of separated tires mounted on an axle, positioned at a loading dock. A member is movable from a stored position near or under the loading dock to an operative position under the vehicle and located between said separated tires. A pair of restraining elements are mounted on the movable member and are movable from a stored position between the tires to an outward extended position where each of the restraining elements engage a respective one of said pair tires. A mechanism, such as an hydraulic system, is mounted to said member at one end and to a fixed point at the other to move the member to a position under the vehicle. The pair of restraining elements is moved to the outward extended position by action of the moving mechanism for the member or by movement of a sensor that contacts a tire.

Abstract: A chocking device for securing a vehicle at a loading dock having a guide rail mountable to a driveway and a carriage movable on the guide rail. A drive mechanism, which may be hydraulic or electric is employed to advance the carriage from a stored position to a position proximate to a wheel of the vehicle. A chock assembly is pivotedly mounted on the carriage and is movable by the drive mechanism from a retracted position to an engaging position. The chock assembly comprises an arm having a sensor bar to contact one portion the wheel and a chock plate movable in response to contact of the sensor against the wheel to contact another portion of the wheel and block movement of the vehicle. A lock assembly is mounted on the guide rail for movement thereon, and is moved by the drive mechanism into contact with the chock plate to restrain the chock plate in the extended position.

Abstract: A dock leveler and installation thereof having a bumper assembly to protect the deck and the lip of the leveler. In one embodiment the dock leveler comprises a pivotable deck and a lip attached to the deck at one end thereof. A bumper is operably connected to the deck and moveable with the deck. The bumper is selectively moveable to protrude beyond the end of the deck to protect the dock leveler from impact. In another embodiment a dock leveler installation comprises a loading dock having a front face. A dock leveler is mounted at the loading dock and has a pivotable deck and a lip attached to the deck at one end thereof. A bumper is operably connected to the front face beneath the dock leveler and projecting in front of the lip when the lip is in a pendent position.

Abstract: A vehicle restraint employs a 4 bar linkage to lift a restraining member to a position that engages a vehicle thus restraining it at a loading dock. The linkage is upwardly biased to hold the unit in an engaging position and may be retracted by using any of a number of mechanical techniques such as hydraulic electric or pneumatic power. The 4 bar linkage transfers all loading on the unit from the ICC to the frame thus isolating any driven members from overloads. A secondary hook mounted to the 4 bar linkage is pivotally spring loaded to limit vehicle travel away from the dock and to extend the capture range of the device in the case of ICC's bars that are damaged or mounted at non-standard positions at the rear of the vehicle.

Abstract: An adjustable bumper system for use at a loading dock which has a dock leveler having a deck pivotally mounted to a portion of the dock. The dock leveler has a lip pivotally attached to one end of said deck. The bumper system has a pair of support members each mounted to a portion of the dock. The support members may be pivotally mounted and extend along sides of the deck of said dock leveler. The support members may also be mounted to the dock face and move vertically. Dock bumpers are mounted to each support member and are positionable between two different vertical positions as the support member is moved. The dock bumpers project outward from the dock beyond the pendent lip and are adjustable to engage the rear of vehicles having different heights.
