ABSTRACT:
A laser lighting assembly, or another type of a directed high intensity collimated beam of light assembly, mountable on a forklift, or like purpose lifting and carrying equipment, to project at least one light beam, which is always directed parallel to and in the same plane as a fork or pair of forks, which are movably mounted on the lifting and carrying equipment for being raised and lowered. The projected light beam, during operations of the forklift, reflects from a changeable spot location on a load to be lifted, which is supported on a pallet, or is supported on a like fork receiving structure. When the fork is being either raised or lowered to be inserted, for example, in a fork receiving volume of a pallet, an operator of the forklift is observing the changeable spot location. When the changeable spot location is no longer reflecting from the load, and, in effect disappears, as the light beam projects into a fork receiving volume below the load, then the operator knows he or she has the fork, or pair of forks, or a like projecting support, positioned at the same elevation of the fork receiving volume. Thereafter, when the lifting and carrying equipment is moved forward, the fork accurately moves into the fork receiving volume, and no portion of a fork touches any portion of the load supported on a pallet, or on another like fork receiving load supporting structure, whereby the supported load is kept free of any possible damage to be otherwise possibly caused by a contracting fork.
