Abstract: An example wheel restraint includes a wheel chock that is manually movable between a retracted or release 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 release 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 release 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 release position, the locking feature automatically disengages. Although the wheel chock is connected to a track, much of the force exerted by the wheel against the chock can be transmitted directly from the chock to the driveway.

Abstract: A wheel restraint for restraining a vehicle at a loading dock includes a wheel chock suspended from a tether. The tether hangs from an overhead beam such that the wheel chock can be swung down and underneath the vehicle and placed directly in front of a wheel of the vehicle. A pin can be used to help hold the chock to an anchor that is fastened to a driveway of the loading dock. The orientation of the pin and the anchor holes in which the pin can be selectively inserted prevents the chock from tipping back and makes the restraint more tolerant of dirt, ice and other contaminants. In some examples, an offset between the beam and the wheel results in the tether urging the chock toward the anchor.

Abstract: To help hold a (trailer) bed of a truck or trailer steady at a loading dock as the truck is being loaded or unloaded of its cargo, a yieldable vehicle brace exerts a substantial, but limited, reactive force upward against the trailer's rear impact guard to resist the trailer's downward movement. In some embodiments, the brace holds the trailer bed stationary up to a certain load limit and provides the trailer bed with a controlled or dampened descent when the load exceeds that limit. In some cases, the reactive upward force exerted by the brace increases with the downward velocity of the trailer bed. The reactive force can be created by one or more pressure relief valves, hydraulic fluid passing through a flow restriction, a brake, a spring, or various combination thereof. Some embodiments of the brace include provisions for accommodating horizontal movement of the rear impact guard.
