ABSTRACT:
A steering device for decreasing a turning radius of a pallet jack includes a ground engaging member connected to a support member of the pallet jack between a main wheel and an extensible wheel. The load supporting member of the pallet jack is positionable between a raised position and a lowered position. A first turning radius of the pallet jack is defined by the distance between the main wheel and the extensible wheel. While the extensible wheel engages the ground when the support frame is positioned towards the raised position, positioning the support member towards the lowered position engages the ground engageable member with the ground causing the extensible wheel to disengage the ground. The main wheel and the ground engageable member then define a second turning radius which is less than the first turning radius.
