A head pad assembly for a loading dock includes a back plate having a forward end and an opposing rear end proximate to a wall of the loading dock. A compressible pad positioned above and extending across an opening to the loading dock is coupled to the back plate. A hinge element provides pivotal rotation of the back plate and pad between an upper position and a lower position, wherein the lower position is configured to engage and seal the compressible pad against a roof surface of the trailer. An actuator assembly is configured to rotate the back plate and pad from the upper position to the lower position. In one embodiment, the back plate comprises a plurality of head pad subassemblies pivotably joined with a flexible hinge so as to allow vertical rotation of one subassembly relative to an adjoining subassembly when the head pad is actuated.

A convex wheel chock includes a contact surface generally facing a vehicle tire, a support element connected to the contact surface to transfer a tire load from the contact surface, and a base portion coupled to the support element to provide structural support to the wheel chock and transfer the tire load to a ground surface. The contact surface includes a convex surface to be engaged by the tire, extending generally upwards from the base portion to the support element, and a concave extension surface joined to an upper end of the convex surface.
A dock bumper for a loading dock includes a rear mounting plate for use in securing the dock bumper to a loading dock wall, a front contact surface configured to engage a vehicle backing into the loading dock, and an elastomer spring block positioned between the rear mounting plate and the front contact surface. The elastomer spring block includes an elastomeric material defining a pattern of geometric cavities. The geometric cavities are configured to provide a progressive spring rate in a longitudinal direction relative to the loading dock.

An air moving device includes an outer casing comprising an outer diameter, an inner portion defining a flow path, an inlet portion defining an inlet cross-sectional area, and an opposing outlet portion defining an outlet cross-sectional area. A motor assembly is disposed within the outer casing, and a hub and blade assembly is secured to a shaft on the motor assembly. The air moving device further includes a de-swirl vane package. The package includes a plurality of de-swirl vanes disposed in the flow path. The blades are characterized by one or more resonant frequencies, and a potential excitation source of the blade resonant frequencies is a flow path obstruction comprising a plurality of objects substantially equally spaced about the circumference of the flow path. The flow path obstruction is characterized by a periodic frequency. The periodic frequency differs from the blade resonant frequencies by a safety margin of at least 20%.
A head pad assembly for a loading dock includes a frame structure secured to a loading dock wall and a head pad portion coupled to the frame structure. The head pad portion is positioned above and extends across an opening to the loading dock and is moveable between an upper position and a lower position.
