ABSTRACT:
Safety supporting devices to automatically securely maintain the rearwardly tilted elevated condition of the cargo dumping box of overland drayage vehicles are provided. The safety supporting device comprises an elongated multi-teeth rack freely pivotably depending from the dump box rearward portion and automatically securely engageable with a detent rigidly mounted to the vehicle chassis. The rack and detent combination maintains the selected degree of dump box rearward tilt. When it is later desired to allow the dump box to descend, vehicular personnel actuatably withdraw the rack from the detent, including desirable optional provision for remotely controlled withdrawal initiatable from the drayman's station e.g. the operator's cab of a dump truck.
