A dock leveler with a pivotal deck includes a stop mechanism that provides the deck with a positive stop at the deck's vertically stored position without the deck's actuator having to be fully extended. With the actuator being less than fully extended, the stop mechanism and actuator can exert opposing forces that help prevent the deck from rocking back and forth as the deck settles to its stationary, upright position. In some cases, the stop mechanism is part of a combination stop-and-lock mechanism that includes a locking device for temporary providing a redundant or alternate lock that prevents the deck from descending unexpectedly while the dock leveler is being serviced or repaired.

Stop and lock for a vertically storing dock leveler

A wheel-activated vehicle restraint for use at a loading dock includes a wheel-blocking barrier that is selectively locked to a frame by a latching mechanism that engages an inverted gear rack. Components of the latching mechanism are arranged to prevent spreading apart upper and lower members of the frame members. The latching mechanism includes an alignment device that helps ensure that the teeth of a latching member positively engages the teeth of the gear rack, thus preventing the teeth from coming together peak-to-peak. An upper rail of the wheel restraint's frame includes a contoured leading edge that smoothly guides the lift of the wheel-blocking barrier from its stored position to its wheel-chocking position. A wheel support is used to prevent a vehicle's mud flap from getting pinched between the vehicle's wheel and a trigger assembly of the wheel restraint.
