Abstract
A pallet jack includes a base and a pair of tines extending from the base. The pair of tines including a first tine and a second tine. A load wheel supports an outer end of each of the pair of tines. Each load wheel is configured to move toward and away from the respective tine to raise the tine off a floor on which the load wheel is supported. The first tine including a support surface configured to selectively be a lowermost surface of the tine to facilitate lateral displacement of the first tine.
Claims19
A pallet jack comprising:
- a base;
- a pair of tines extending forward from the base, the pair of tines including a first tine and a second tine, wherein the first tine is selectively movable laterally toward and away from the second tine;
- a first arm pivotably secured to the first tine and pivotable about an axis perpendicular to the first tine;
- a first load wheel mounted at forward end of each of the first arm and supporting an outer end of the first tine;
- a second load wheel supporting an outer end of the second tine;
- wherein each of the first load wheel and the second load wheel is configured to move toward and away from the respective tine to raise the tine off a floor on which the wheel is supported;
- a first push rod in the first tine, the first push rod coupled to the first arm, wherein movement of the first push rod parallel to the first tine causes the first load wheel to move toward or away the first tine;
- and
- the first tine including a first side wheel mounted proximate a rear end of the first arm, the first side wheel configured to selectively be a lowermost surface of the first tine to facilitate lateral displacement of the first tine.
