Abstract
A materials handling vehicle is provided comprising a pair of forks to be inserted in a longitudinal direction of the forks into a pallet having one or more stringers. A pallet clamp device is provided including first and second operating devices, one mounted in each fork for actuating respective punch members into engagement with an adjacent surface on the pallet. Each operating device comprises a module located within a cavity in one of the forks, the module including an actuator, one of the respective punch members, and a linkage structure connecting the actuator and the respective punch member.
Claims27
A materials handling vehicle comprising:
- a pair of forks to be inserted in a longitudinal direction of the forks into a pallet having one or more stringers;
- and
- a pallet clamp device including at least one operating device located in a respective fork for actuating a punch member into engagement with an adjacent surface on the pallet;
- wherein the at least one operating device actuates the punch member in substantially linear movement transverse to the longitudinal direction of the forks;
- and
- wherein the at least one operating device comprises a module including an actuator, the punch member, and a linkage structure connecting the actuator and the punch member, and including first and second pivot connections, wherein the actuator is located between the first and second pivot and is pivotally attached to the respective fork via the first and second pivot connections, wherein at least one of the first and second pivot connections defines a pivot axis that is transverse to the longitudinal direction.
