Abstract:

A laser lighting assembly, mounted on a forklift, will be projecting a light beam parallel to and in the same plane as a fork, which itself is parallel to a floor or ground level. Until the forks are parallel to the floor or ground level the laser light will not be continuously on. When an operator of the forklift is adjusting the forks to be level, and then parallel to the floor or ground level, as the level positions are being approached, the laser light appears in a blinking sequence with the off periods initially being longer and then becoming shorter as the level positions are approached. Then when the level positions of the forks are reached the laser light is on full time. In addition, a laser light beam is provided which projects as a planar beam of light to match the planar location of both of the projecting forks of the forklift, and the operator then, if necessary, adjusts his or her controls of the forklift to insure the forks will also be in the same planar location of the fork receiving volume of the loaded pallet while remaining parallel to the floor or ground level.
