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： A dock leveler for a truck loading dock includes a pivotal deck that is actuated by an inflatable column assembly. The inflatable column assembly includes a pliable tube that when inflated has a generally vertical cylindrical shape that can provide a heavy deck with substantial columnar support. The shape and orientation of the column assembly is such that the lengths of the pliable tube's seams are minimized. A pliable fabric sheet held in tension against the underside of the deck provides a generally flat, broad surface against which the pliable tube can push as the inflatable column assembly pushes the deck upward. A footed pallet underneath the pliable tube can be banded to the deck during shipment. After installation, the pallet can be readily lifted for cleaning the pit floor underneath the pallet.

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.

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.
