    摘要: A dock leveler having safety supports includes a deck movable relative to a platform between a raised position and a lowered cross-traffic position when the dock leveler is in a working configuration, where a first lateral edge and a second lateral edge of the deck are proximate the platform when the deck is in the lowered cross-traffic position and the deck residing at least partially in a pit when the front edge of the deck is in the lowered cross-traffic position. A front edge of the deck is above at least one of the lowered cross-traffic position or the raised position and inhibited from descending toward the lowered cross-traffic position when the dock leveler is in a service configuration. A first deck obstruction is movable relative to a deck between a secured position and an unrestrained position, where the first deck obstruction in the secured position configures the dock leveler in the service configuration and the first deck obstruction in the unrestrained position configures the dock leveler in the working configuration. The first deck obstruction extends farther beyond the outer perimeter of the deck when the first deck obstruction is in the secured position than when the first deck obstruction is in the unrestrained position.

    摘要: Restraints for restraining a vehicle at a loading dock are described. An example restraint described herein includes a brace movable between a holding position and a release position. A first portion of the brace engages a supporting portion of the vehicle and a second portion of the brace engages a non-movable location at the loading dock to restrain the vehicle relative to the loading dock when the brace is in the holding position. For the holding position, the first portion of the brace moves in one direction underneath the vehicle to engage the supporting portion and the second portion moves in a second direction underneath the vehicle to engage the non-movable location. The first and second portions retract to allow the vehicle to move relative to the loading dock when the brace is in the release position.

    摘要: 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.

    摘要: Example dock levelers installed at a vehicle loading dock include pivotal or otherwise vertically adjustable deck plates with special coatings on the deck's upper surface. In some examples, the coating improves traction and addresses various thermal issues, such as condensation and thermal strain between a polymeric coating and a steel deck plate. In some examples, when indoor and outdoor air create a temperature differential across opposite faces of the deck, the coating is designed such that a median temperature of the temperature differential occurs near an interface where the coating bonds to the steel plate's upper surface. In some examples, the coating includes particles of different sizes and colors embedded within and covered by a polymeric base material. As traffic abrades the coating, the different colored particles become exposed at different levels of wear, thereby providing a visual signal indicating when the coating needs to be touched up or replaced.
