Abstract: A method and device allowing a driver of a handling machine of the forklift type to position and introduce, in complete safety, the forks of the machine under a load to be handled. A light-beam that projects a luminous mark onto the load to be handled informs the driver of the relative position of the forks with respect to the load to be handled. The light-beam is activated and adjusted depending on the different steps of handling and inclination of the forks, which, for their part, are identified solely on the basis of the measurement of the acceleration acting on the forks. The device, which is installed quickly and protected effectively against collisions, has a high degree of operational autonomy. It improves working conditions and reduces product losses.

Abstract: A pallet jack is disclosed that comprises a left tine, center tine, and a right tine. The center tine is about 2 times the width of each of the left and right tines, though other widths of the center tine can also be implemented.
