Abstract:
1. A range finding device mounted on a forklift comprising: an emitter of range determining signal; said range determining signal reflects from workpiece pallet load of product; a detector to accept said reflected signal; a processor to analyze sent and reflected signal to determine the range between said emitter and said workpiece pallet load; said range determining information is transmitted from said processor to a distance display device; said distance display device, said emitter, said receiver, and said detector are mounted on said forklift; said forklift has attached tines of a known length; said distance display device informs the forklift operator of the actual distance/range between the floor perpendicular fork and said pallet load so that the operator will know if penetration depth in a base hollow of the pallet load is less than said known tine length and therefore said load can be safely moved.
