Abstract: Technology generally directed to operation of loading dock equipment such as vehicle restraints, dock levelers, overhead doors/openers, barrier gates, lights, and linked or unlinked control systems is disclosed herein. The disclosed technology may be employed to power electrical loading dock systems from batteries and/or alternative power sources, including “green” power sources. For example, the technology may be employed at new, temporary, and/or mobile facilities having any number of loading docks where reliable commercial power may not be readily available. Further, the technology may also be employed at warehouses in remote and/or developing areas where electrical infrastructure is not available and/or reasonably priced. The technology may be embodied as methods, apparatuses, manufactures (e.g., computer- and/or processor-readable storage and/or other mediums), and/or the like.

Abstract: An open-end or box wrench with a ratcheting socket wrench at the opposite end of the wrench handle. The ratcheting socket wrench may be either fixedly or pivotally attached. In one embodiment of the invention, a socket is permanently affixed to the ratchet mechanism. In another embodiment of the invention, a drive member for releasable attachment to sockets is permanently affixed to the ratchet mechanism. In either embodiment, the ratchet mechanism is preferably reversible.

Abstract: An indexible tool (for example, a wrench) in which the handle of the tool stays in a constant horizontal plane with respect to the horizontal plane of the head of the tool and the tool has locked and unlocked positions through a movable splined pin connecting the head and the handle of the tool.
