Abstract
A lift for a fork tine assembly includes a generally upright frame having at least one handle grip portion at a rearward portion thereof. The handle grip portion is fixed relative to the frame. A lift mechanism is secured to the frame. The lift mechanism is capable of attaching to and raising and lowering at least one fork tine. A plurality of wheels support the frame. The at least one fork tine may be part of a first fork tine assembly that can be selectively removed from the lift and replaced with a different configuration fork tine assembly. An optional shelf is provided on the frame for convenience but may be pivoted out of the way when not in use.
Claims9
A method for operating lift assembly including the steps of:
- a) selectively connecting a first fork tine assembly to a lift, wherein the first fork tine assembly includes a pair of first fork tines connected to one another by a first cross-beam, the first fork tine assembly further including a first push rod within each first fork tine connected to a first wheel pivotably connected to the first fork tine;
- b) lifting and moving at least one pallet with the first fork tine assembly;
- c) after said steps a) and b), removing the first fork tine assembly from the lift;
- d) after said step c), selectively connecting a second fork tine assembly to the lift, wherein the second fork tine assembly includes a pair of second fork tines connected to one another by a second cross-beam, the second fork tine assembly further including a second push rod within each second fork tine connected to a second wheel pivotably connected to the second fork tine;
- and
- e) lifting and moving at least one pallet with the second fork tine assembly.
A method for operating lift assembly including the steps of:
- a) selectively connecting a first fork tine assembly to a lift, wherein the first fork tine assembly includes a pair of first fork tines connected to one another as a single unit, the first fork tine assembly further including a first push rod within each first fork tine connected to a first wheel pivotably connected to the first fork tine;
- b) lifting and moving at least one pallet with the first fork tine assembly;
- c) after said steps a) and b), removing the first fork tine assembly from the lift;
- d) after said step c), selectively connecting a second fork tine assembly to the lift, wherein the second fork tine assembly includes a pair of second fork tines connected to one another as a single unit, the second fork tine assembly further including a second push rod within each second fork tine connected to a second wheel pivotably connected to the second fork tine, wherein the first fork tine assembly has a fork tine configuration that is different from the second fork tine assembly;
- and
- e) lifting and moving at least one pallet with the second fork tine assembly.
