Abstract
A system to determine the usage of loading dock equipment such as a dock leveler, a vehicle restraint and a barrier gate to provide an output indicative thereof. For each loading dock component mounted at a loading dock in an operable configuration whose operation is to be monitored, sensor outputs are used to provide data accumulated by PLC's located in a control panel associated with the loading dock. When operation of a piece of equipment is initiated the occurrence delivers an output signal to the PLC. A counting circuit accumulates a count of the output signals. The panel has displays in the form of lights and screens and the data maybe read out by means of a hand held unit for display and/or programing or delivered to a remote PC by appropriate cable.
