A fork lift apparatus is mounted on a truck for picking up a load, placing the load in a traveling position on the truck, and for unloading the load. The apparatus comprises a lift frame, a shaft, a pair of spaced arms secured to the shaft, a cross member spanning between the distal ends of the arms distal and carrying the forks. The cross member is rotatable relative to the support arms. A pair of drive hydraulic cylinders rotates the shaft and thus moves the arms and the load between a loading/unloading position in which the load may be placed on the forks and the traveling position so that the load may be transported by the truck. A self-leveling system is provided for maintaining the load in a substantially level position as it moves between its loading/unloading and traveling positions.

An Automated Guided Robot (AGV) system designed for carrying, storing and retrieving inventory items to and from storage shelves. The AGV (100) can move between warehouse shelves and reach to the inside of a shelf without turning. The AGV (100) is equipped with a material handling device (130). The material handling device (130) comprises a lateral device that is configured to move in a lateral direction either to the right side or to the left side. The movement of the lateral device can be either rotational or translational. The material handling device (130) further comprises a retractable device that retracts or extends in a direction perpendicular to the lateral direction. The retractable device allows the material handling device (130) to extend into the storage shelf to fetch or place an inventory item.

A materials handling vehicle including a power unit supported on wheels, and a mast assembly supported on the power unit. The mast assembly includes four or more telescoping sections defined by pairs of laterally spaced rails. An operator compartment is supported on the mast assembly for vertical movement relative to the mast assembly and includes a front wall defining a side of the operator compartment adjacent to the mast assembly. The laterally spaced rails have a height that is generally equal to the height of the front wall. A dash is located adjacent to the operator compartment.
