US Patent 7976032 Pallet jack apparatus

The pallet jack apparatus provides lateral fork adjustment between the two forks, each having a forwardly disposed pivoted wheel for added fork support. The lateral fork adjustment is controlled by the horizontal control lever on the stem. The lateral fork adjustment is via a motor with pinion gear which directly drives the first and second fork gears. The apparatus further provides height adjustment for the forks via the vertical control lever on the stem. The control levers are positioned within the handle interior of the oblong circular handle which guards against inadvertent control movements while providing superior leverage for positioning the apparatus.
