Abstract
A pallet lift includes a pair of outer tines movable between an expanded position spaced outward away from inner tines and a retracted position adjacent the inner tines. The inner and outer tines are supported by wheels at locations spaced away from the lift mechanism. A pallet includes a plurality of nestable feet that open outwardly of the pallet to reduce the footprint. A second pallet includes a side wall extending downward from side edges of the pallet to define an opening adjacent outer feet.
Claims20
A pallet lift comprising:
- a lift mechanism;
- a pair of tines connected to the lift mechanism, the pair of tines movable between a retracted position a first distance apart from one another and an expanded position spaced a second distance apart from one another, wherein the second distance is greater than the first distance, wherein the pair of tines are movable in a lateral direction from the retracted position to the expanded position;
- and
- at least one outer wheel supporting each of the pair of tines, wherein the pallet lift is capable of lifting each at least one outer wheel off a floor on which the pallet lift is supported while the tines are being moved to the expanded position from the retracted position, wherein a widest lateral dimension of a footprint of the pallet lift is wider when the pair of tines are in the expanded position than when the pair of tines are in the retracted position.
A pallet lift comprising:
- a lift mechanism;
- a pair of tines secured to the lift mechanism, the pair of tines movable between an expanded position spaced a greater distance from one another and a retracted position spaced a lesser distance from one another;
- and
- at least one outer wheel supporting each of the pair of tines, wherein the pallet lift is capable of lifting each of the tines to lift the at least one outer wheel off a floor while the tines are being moved to the expanded position from the retracted position, wherein the pair of tines are movable in a lateral direction from the retracted position to the expanded position and wherein a widest lateral dimension of an overall footprint of the pallet lift is wider when the pair of tines are in the expanded position than when the pair of tines are in the retracted position.
A method for adjusting a pallet lift between a retracted position in which a pair of tines are a first distance apart from one another and an expanded position spaced a second distance apart from one another, wherein the second distance is greater than the first distance, the method including the steps of:
- a) while each of the pair of tines is parallel to a floor on which the pallet lift is supported, lifting an outer wheel supporting each of the pair of tines off of the floor by lifting each outer wheel relative to the respective one of the pair of tines;
- b) while the outer wheels are lifted off the floor after said step a) and while the pair of tines are parallel to the floor, moving the pair of tines between the expanded position and the retracted position, including moving the pair of tines away from one another from the retracted position to the expanded position, wherein a widest lateral dimension of an overall footprint of the pallet lift is wider when the pair of tines are in the expanded position than when the pair of tines are in the retracted position;
- and
- c) after said step b), lowering the outer wheels to the floor, wherein the pair of tines remain parallel to the floor during said step c).
