Abstract: A wheel restraint includes a wheel chock that is manually movable between a retracted position clear of a wheel of a vehicle at a loading dock and an operative position to block the path of the wheel. In the retracted position, the chock can be manually moved freely along a track that is mounted to a driveway of the dock. When the chock is manually moved from its retracted position to its operative position, a locking feature automatically restricts the movement of the chock relative to the track. When the chock is manually moved back to its retracted position, the locking feature automatically disengages. Although the wheel chock is connected to a track, most of the force exerted by the wheel against the chock is transmitted directly from the chock to the driveway.

Abstract: A safety system for a truck loading dock with an elevated platform provides an alarm that warns of a hazard at the loading dock such as a forklift operating inside the truck or a falling hazard that may exist due to the dock door being open while a truck is not present at the dock. In cases where a dock's open doorway is protected by a barrier that can be opened or closed, the alarm can be de-activated by closing the barrier. In some embodiments, the safety system includes a remote body sensor that detects when someone or something is near the doorway. In response to the body sensor, a second, more pronounced alarm can warn of more imminent danger where someone on the platform may be too close to an open doorway when a truck is not present.

Abstract: Vehicle restraint systems are disclosed herein. An example vehicle restraint system includes a base to be positioned adjacent a loading dock and a wheel chock to be positioned on the base. An actuator is coupled to the base and moves the base relative to a wall of the loading dock in a linear direction between a release position and a holding position when the wheel chock is coupled to the base. In the release position, the wheel chock disengages from a wheel of a vehicle positioned at the loading dock. In the holding position, the wheel chock frictionally engages the wheel of the vehicle to restrict movement of the wheel away from the loading dock.

Abstract: A wheel restraint for restraining a vehicle at a loading dock includes various features such as, a wheel chock supported by a spring loaded articulated arm with a spring that can be selectively tightened or released, a sensor that detects whether the chock is solidly against a base plate or floor, a bi-directional pivotal joint between the articulated arm and the wheel chock to ensure that the chock can sit squarely on a mating base plate, a wheel chock that meshes with a hydraulically actuated base plate, pivotal or otherwise movable backstops that prevent a wheel chock from sliding out of position, and a base plate cleaning system. The cleaning system might include a vehicle-actuated brush, fluid spray nozzles, electric heater and removable cover plates.

Abstract: A dock leveler includes a vehicle-engaging pivotal lip extending from the front end of a pivotal deck, wherein the lip has one or more unique features that provide a smooth transition for forklifts traveling between the lip and a trailer bed upon which the lip is resting. The smooth transition minimizes jolting and vibration of the forklift and its driver as the forklift wheels pass over the leading edge of the lip. The special features of the lip may include one or more of the following: a curved traffic-bearing surface terminating at a sharp or blunt leading edge, a traffic-bearing surface that includes both flat and curved sections, a multifaceted traffic-bearing surface that approximates a curved surface, a rubber or plastic shock absorbing element, an articulated nose piece at the lip's leading edge, and a main lip plate that is coplanar with the deck's traffic surface (i.e., zero crown angle).

Abstract: A hydraulic system for operating dock levelers, vehicle restraints, and other types of loading dock equipment includes one or more features that prolong the life of the hydraulic fluid. A hydraulic reservoir with a desiccant filled breather cap or a hermetically sealed pliable reservoir minimizes the hydraulic fluid's exposure to condensation and atmospheric moisture. The system can be used for prolonging the life of both biodegradable and- non-biodegradable hydraulic fluids. In some embodiments, the system includes an acceptably biodegradable fluid having a combination of properties that makes the fluid particularly suitable for loading dock equipment.
