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.
Claims18
A pallet jack comprising:
- a base;
- a pair of tines extending from the base, the pair of tines including a first tine and a second tine, wherein the first tine is selectively moveable toward and away from the second tine;
- a load wheel supporting an outer end of each of the pair of tines, wherein each 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;
- and
- 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.
A method for operating a pallet jack including:
- a) moving a first tine away from a second tine while the first tine is supported on a floor by a support surface lower than a first load wheel below an outer end of the first tine;
- b) after step a), deploying the first load wheel such that it contacts the floor and such that the support surface does not contact the floor;
- and
- c) after step b), moving the first load wheel away from the first tine to raise the first tine relative to the floor.
A method for operating a pallet jack having a first tine and a second tine, the first tine having a first load wheel therebelow, the second tine having a second load wheel therebelow the method including:
- a) moving the first tine away from the second tine while the first tine and the second tine are supported on a floor by support surfaces lower than the first load wheel and the second load wheel;
- b) after step a), deploying the first load wheel below the first tine and a second load wheel below the second tine;
- and
- c) after step a), moving the first load wheel away from the first tine to raise the first tine relative to the floor and moving the second load wheel away from the second tine to raise the second tine relative to the floor, such that the support surfaces no longer contact the floor.
