Abstract: Apparatus for use in a loading dock area to prevent any wheeled apparatus from accidentally falling off the loading dock. The leveler includes a ramp for supporting a load between a truck and a platform and also used to actuate a barrier, the barrier is operatively connected to the ramp through a plurality of links. The invention operates through the position of the ramp in relation to the platform top surface. When the dock leveler is in the stored position the ramp is at a 90.degree. angle to the dock leveler top surface. In this position the linkage has rotated the stop such that it protrudes above the surface of the deck. Thus forming the barrier so that no wheeled vehicles could accidentally roll off the end of the dock. When the dock leveler is below a level position, the linkage no longer acts to supports the barrier, so that the barrier falls back to the surface of the dock leveler, no longer forming a barrier.

Abstract: A knock-down pallet truck utilizes a tubular construction as its fork assembly (43) such that each fork is separately removable from the carriage. Each light-weight fork (43) includes a pair of spaced apart tubular members (39) joined at a tip (41) and affixed to a pair of rigid connection splines (36) which are detachably affixed to a receptacle unit (18, 19) on the body (14) of the pallet truck.

Abstract: A rider truck lift utilizes a see-through mast assembly and a forwardly positioned rider compartment to improve visibility of the load for the operator. The rider compartment is accessible from either side of the truck and comprises a low-rise deck which allows for one-step ingress and egress. A pseudo-tricycle wheel arrangement provides for a tandem articulated rear wheel steering assembly that reduces tire wear and improves maneuverability.

Abstract: A dock leveller for releasable securement to a loading dock installation is disclosed. The dock leveller comprises a main frame with a ramp hinged to the main frame for swinging movement. Securement devices are provided for releasably securing the dock leveller to the dock installation. The securement devices comprise at least one latch for connecting the main frame to the dock installation. The arrangement of latches is such to fix securely the dock leveller to the dock for withstanding traffic over the ramp.

Abstract: A lip construction for pivotal connection to the ramp of a dock leveller is disclosed. The lip comprises upper and lower rectangular steel plates providing front and rear lip edge portions. Means is provided for securing the lip rear edge portion for pivotal connection to a dock leveller ramp. The steel plates are bent along their lengths to define first and second lip portions which are slightly angled relative to each other. The lower plate extends slightly outwardly of the upper plate front portion, where the upper plate is secured along its front portion to the lower plate extension. The upper plate is also secured to the lower plate along the first lip portion. This arrangement places the upper plate of the second lip portion in compression and corresponding lower plate in tension when a load is applied to the lip during use.
