    摘要： A dock leveler for a truck loading dock includes a pivotal deck that is raised by an inflatable actuator. The actuator includes a pliable upper section that when inflated has a generally vertical cylindrical shape that can provide a heavy deck with substantial columnar support. The actuator also includes a relatively rigid base that is sealingly joined to the pliable upper section such that upper section and the rigid base define an inner chamber of air. A blower for inflating the actuator can be installed inside or outside the actuator. In some embodiments, a valve system reverses the airflow so that the blower can forcibly deflate and compress the actuator up against the bottom of the deck so that the area underneath the actuator can be cleaned.

    摘要： 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.

    摘要： Two embodiments of a slope extension are disclosed herein for use with a vehicle restraint. In each embodiment, the vehicle restraint is adapted to releasably secure a parked trailer or other vehicle to an adjacent structure, such as a loading dock, and includes a carriage assembly which is adjustably mounted in proximity to the adjacent structure for movement relative to a roadway, and a restraining member which is operatively attached to the carriage assembly. In operation, each embodiment of the inventive slope extension interacts with the carriage assembly to avoid a "dead lock" condition wherein the carriage assembly is obstructed from moving downwardly toward the roadway.

    摘要： Vehicle restraint including a support mounted adjacent a loading structure. A carriage is supported from the support and has a generally horizontal portion extending over the roadway, the horizontal portion being operatively engageable with the vehicle bar over a vertical range. A vertically elongate barrier is supported from the carriage and is disposed remotely from the upright loading structure, the barrier being mounted for generally vertical movement with respect to the carriage between an inoperative vehicle-released position wherein the barrier is disclosed below the horizontal portion, and an inoperative vehicle restraining position, wherein the barrier extends vertically a fixed distance above the horizontal portion to define a vehicle bar capture distance along the horizontal portion.

    摘要： Dock leveler safety supports are disclosed herein. An example dock leveler disclosed herein 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. The deck to be 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 the deck between a secured position and an unrestrained position. The first deck obstruction in the secured position configures the dock leveler in the service configuration. The first deck obstruction in the unrestrained position configures the dock leveler in the working configuration. The first deck obstruction in the secured position to block movement of the deck toward the lowered cross-traffic position and the first deck obstruction in the unrestrained position to permit movement of the deck toward the lowered cross-traffic position. A first connector to couple the first deck obstruction to an obstruction actuator. The first connector including a rod, a sleeve to telescopically receive the rod, and a spring held in compression between the rod and the sleeve.

    摘要： Dock leveler safety supports and related methods are disclosed. An example method includes raising a front end of a deck above a platform, where the front end is elongate in a lateral direction and the front end extends laterally between a first side and a second side of the deck. The method includes manually pulling a first deck obstruction in the lateral direction out from the first side so that the first deck obstruction extends out over a perimeter of the platform. The method further includes lowering the front edge of the deck until the first deck obstruction descends upon and engages the platform.
