ABSTRACT:
A motor driven carriage includes nozzles for directing a cleaning solution to the inside of a trailer on an inward trip and means for stopping movement of the carriage as it approaches the front wall of the trailer. The return cleaning trip is delayed until the rinse water has cleared the cleaning solution from the supply hose. Several alternative dock arrangements are described whereby the carriage-mounted cleaning system may be used for cleaning trailers backed up to opposite sides of the dock, for trailers driven along-side the dock, or for cleaning a plurality of trailers each backed up to the same side of an elongate dock. The heating water and rinse water supply, storage and heating systems of the invention are described, as are the systems for permitting recirculation of water with the various dock arrangements. Finally, a system is described which permits diversion of water draining from the trailers, a feature which is especially valuable if a pre-rinse of dirty trailers is desired or required by the nature of the materials transported in the trailer prior to cleaning.
