A maintenance and retrieval cart is provided for use with a push back storage rack having a plurality of nested trays riding on a pair of inclined rails. The maintenance and retrieval cart can be utilized to permit the safe and efficient inspection, maintenance and repair of push back rack systems, and to provide access to racking bays to enable an operator to clear jams. The maintenance and retrieval cart comprises a base with a safety rail secured thereto. The base is supported on an undercarriage which facilitates movement along the inclined rails. A drive mechanism is operatively connected to move the cart along the inclined rails.
The present invention relates to a trailer safety stand for temporarily supporting a conventional trailer having a landing gear, wherein the stand comprises a pedestal having a top for engaging the underside of the nose portion of a trailer and a bottom for engaging the ground; means for adjusting the height of the pedestal; a locking device for fixing the height of the pedestal; and means for actuating and de-actuating the locking device. In one embodiment of the present invention, the means for actuating and de-actuating the locking device is a lever that is pivotally connected to the pedestal at a first point along the lever and connected to the locking device at a second point along the lever. When a force is applied away from the pedestal at a third point along the lever, the locking device is actuated and the height of the pedestal is fixed. When a force is applied toward the pedestal at the third point along the lever, the locking device is de-actuated and the height of the pedestal is adjustable.

Loading dock bumper with replaceable metal faceplate
A bumper assembly for use at a loading dock comprises a resiliently compressible pad protected by a readily replaceable metal faceplate. The bumper assembly has certain metal components that move relative to each other as the bumper assembly is compressed by a vehicle backing into the dock. Those metal components are spaced apart from each other to avoid metal-to-metal frictional wear. In some cases, the compressible pad has internal cavities that help reduce the extent to which the core bulges under compression.
