Abstract
A walkie/rider pallet truck is provided comprising a power unit; a set of forks associated with the power unit; a platform associated with the power unit and defining a location upon which an operator may stand; and a restraint system comprising a pivotable restraint structure. The restraint structure is movable to one of a walkie position, a rider-driving position and a quick-exit position.
Claims20
A walkie/rider pallet truck comprising:
- a power unit;
- a set of forks associated with said power unit;
- a platform associated with said power unit and defining a location upon which an operator may stand;
- and
- a restraint system comprising a pivotable restraint structure, said restraint structure being movable to one of a walkie position, a rider-driving position and a quick-exit position, wherein the quick-exit position is located generally vertically above the walkie and rider-driving positions.
A walkie/rider pallet truck comprising:
- a power unit comprising a drive/braking system;
- a set of forks associated with said power unit;
- a platform associated with said power unit and defining a location upon which an operator may stand;
- a controller to control the operation of said drive/braking system;
- a restraint system comprising a pivotable restraint structure, said restraint structure being movable to a quick-exit position;
- and
- sensor apparatus to sense when said restraint structure is in said quick-exit position and generating a corresponding quick-exit position signal to said controller, said controller generating a brake command signal to said drive/braking system in response to receiving said quick-exit position signal from said sensor apparatus.
A walkie/rider pallet truck comprising:
- a power unit comprising a drive/braking system;
- a set of forks associated with said power unit;
- a platform associated with said power unit and defining a location upon which an operator may stand;
- a controller for controlling the operation of said drive/braking system;
- a restraint system comprising a pivotable restraint structure, said restraint structure being movable to one of a walkie position, a rider-driving position and a quick-exit position;
- and
- sensor apparatus to sense when said restraint structure is in said quick-exit position and to generate a quick-exit position signal to said controller.
A walkie/rider pallet truck comprising:
- a power unit;
- a set of forks associated with said power unit;
- a platform associated with said power unit and defining a location upon which an operator may stand;
- and
- a restraint system comprising first and second pivotable members, each of which is movable to one of a walkie position, a rider-driving position and a quick-exit position, wherein the quick-exit position is located generally vertically above the walkie and rider-driving positions.
A walkie/rider pallet truck comprising:
- a power unit;
- a set of forks associated with said power unit;
- a platform associated with said power unit and defining a location upon which an operator may stand;
- and
- a restraint system comprising first and second pivotable members, each of which is separately movable about a substantially vertical axis between a stowed position and a rider-driving position and further separately movable about a substantially horizontal axis between the rider-driving position and a quick-exit position.
