A dock leveler for bridging the gap between a loading dock and the bed of a vehicle parked at the loading dock. The dock leveler is configured for installation on the top of the dock and is designed to rotate from a vertically-stored raised position to at least one lowered, operative position. In some embodiments, the dock leveler can be lowered either for normal operation so that the deck assembly rests on the bed of the vehicle or it can be lowered to accommodate an end-loading condition.

Vertically-storing dock leveler apparatus and method

A dock leveler support frame includes an upper frame member and a substantially vertical frame member connected thereto. The substantially vertical frame member includes both a structural member and a height-adjusting leg assembly. The leg assembly is adjustable via a drive member proximate the upper frame member. Rotating the drive member raises or lowers the upper frame member by altering the distance between the upper frame member and a foot at the lower end of the leg assembly. Ramp attachment points are also provided proximate the upper frame member. The support frame is installed by placing it in a pit with the upper frame member adjacent the curb, and adjusting the leg assembly to level the upper frame member to the curb. Once level, the back frame is secured to the dock, and the drive member may be secured to the upper frame member to prevent counter-rotation.

A loading dock apparatus remote control is provided. Some embodiments of the invention include a zone specific remote control for loading dock apparatus. Some optional embodiments include a selector switch to select which apparatus the single set of controls will control. Other optional embodiments automatically select the apparatus to be controlled by the single set of controls. A method of operating loading dock apparatus using a remote control is also provided.

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.

Support leg system and method for supporting a dock leveler

A dock leveler for bridging the gap between a loading dock and the bed of a vehicle parked at the loading docket. The dock leveler is configured for installation on the top of the dock and is designed to rotate from a vertically-stored position to at least one lowered, operative position. In some embodiments, the dock leveler can be lowered either for normal operation so that the deck rests on the bed of the vehicle or it can be lowered to accommodate an end-loading condition. The docket leveler has a horizontally translatable ramp.

A valve circuit, including a first and second circuit portion, for hydraulically controlling a loading dock vehicle restraint. The first circuit portion permits raising and lowering of the vehicle restraint. The second circuit portion permits extension and retraction of the vehicle restraint. Preferably, the first and second circuit portion are separate and are configured on the same valve block.

An 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.

A counter balance mechanism for a mechanically-operated, vertically-storing dock leveler that can upwardly bias the dock leveler at desired angles of rotation and downwardly bias the dock leveler at other angles of rotation, and neutrally bias the dock leveler at yet other angles of rotation. A method for assisting the operation of a mechanically-operated, vertically-storing dock leveler of desirable simplicity is also provided.

The present invention provides a radiation source module for use in a fluid treatment system. In one embodiment, the module comprises: a substantially elongate first support member having a longitudinal first axis; and a first pair of radiation source assemblies extending from the first support member, each radiation source assembly comprising a radiation source; wherein the first pair of radiation source assemblies is oriented such that a second axis extending through a center point of each radiation source assembly is disposed at an angle with respect to the first axis. In another embodiment, the module comprises a substantially elongate first support member having a longitudinal first axis; and a first column of radiation source assemblies extending from the first support member, and a second column of radiation source assemblies extending from the first support member, each radiation source assembly comprising a radiation source; the first column of radiation source assemblies and the second column of radiation source assemblies disposed adjacent one another.
