ABSTRACT:
A load position sensing device for load carriers, such as the fork lift of a fork lift truck, wherein the load carrier includes vertical support means and horizontal load-carrying means extending forwardly therefrom, comprising a plate mounted pivotally onto the vertical support means of said load carrier and movable toward and away from the vertical support means in the direction in which the horizontal load-carrying means extends, spring means biasing the plate away from the vertical support means, position sensing means to detect when the load is within a proper range or too close to the vertical support means, and indicator means to communicate the position sensed to an operator of the load carrier whereby potential damage to loads of frangible goods is minimized.
