Abstract: The present magnet holder and magnetic sensor bracket provide a robust, easily repaired magnet-and-sensor system. The axle extending through the holder and bracket is easily aligned in a shaft collar in the holder by an interlocking keyway. A slot extending through the collar allows deformation of the split collar to accommodate over-rotation without damage to the collar. The magnet assembly in the holder is held in place based on magnetic attraction, allowing both easy assembly and replacement. Likewise, the potential sensor attachment methods allow easy, rapid fabrication and replacement using assemblies with split sensor channels and retaining rings.

Abstract: The present invention is a vehicle restraining hook. The hook includes a shank extending between an axle interface and a hook bend. The hook bend comprises an inner hook surface extending between the shank and a hook tip. The inner hook surface comprises at least a primary bend and a secondary bend, and in some cases a tertiary bend. Each of the primary bend and secondary bend comprises two planar surfaces, while the tertiary bend comprises a curved surface. These surfaces interact with a RIG bar to generate a force rotating the hook up and ensuring that it maintains contact with the RIG bar.

Abstract: A method and apparatus for supporting a dock leveler in a manner to reduce the effects of free fall and stump-out. The apparatus includes the use of a retractable support leg. The method includes maintaining the support leg in a support position and retracting the support leg under certain conditions.
