A transport device for transporting a cryopump includes a bogie that includes a front wheel and a rear wheel, a mast that extends from a front side of the bogie in a height direction, a raising and lowering unit that is supported by the mast and that has a changeable height, a guide rail that extends forward from the raising and lowering unit, an arm that is supported by the guide rail and that is slidable in a front-rear direction, a cargo platform that is provided at a tip part of the arm and that holds the cryopump, and a counterweight that is provided on a rear side of the bogie.

A materials handling vehicle is provided comprising a power unit, a mast assembly and a fluid supply system. The mast assembly is coupled to the power unit. The mast assembly comprises a weldment, a movable element and a ram/cylinder assembly coupled to the movable element to effect movement of the element. The fluid supply system includes manifold apparatus and at least one fluid line coupled to the manifold apparatus and the ram/cylinder assembly. The manifold apparatus provides pressurized hydraulic fluid to the ram/cylinder assembly via the fluid line to raise the movable element. The manifold apparatus is mounted to the mast assembly.

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.

The present invention relates to an industrial truck (10) comprising a truck body (12) having a longitudinal direction and a width direction, a mast (20) which extends substantially vertically from the truck body (12), an active position control system (22) which is adapted to effect a relative movement of the mast (20) relative to the truck body (12), at least one support member (28) which extends between a first attachment point (24) on the truck body (12) and a second attachment point (26) on the mast (20), and a support element adjustment system (30) which is adapted to adjust a length of the support element (28) when the mast (20) moves relative to the truck body (12) so as to compensate for the resulting relative displacement of the second attachment point (26) relative to the first attachment point (24). The invention further relates to a method of operating such an industrial truck.

A material handling limitation device for a forklift including an engine and a material handling device is provided. The material handling limitation device includes a vehicle speed sensor configured to output a signal corresponding to a vehicle speed of the forklift, an accelerator sensor configured to output a signal corresponding to an operation amount of an accelerator pedal, and a processing circuitry configured to calculate the vehicle speed based on the signal from the vehicle speed sensor, execute a vehicle speed limiting process that limits the vehicle speed based on at least the vehicle speed, and execute, in a case where an anomaly related to the vehicle speed limiting process has occurred, a traveling process that controls a rotational speed of the engine based on the signal from the accelerator sensor and a material handling limitation process that limits operation of the material handling device.

Apparatus and associated methods relate to a rearward mast forklift chassis. In an illustrative example, the rearward mast forklift chassis may include a fixed mast extending along a longitudinal axis positioned behind an axle of the front wheels of a forklift. The rearward mast forklift chassis may include a forklift device extending over the axle of the front wheels coupled to the fixed mast. The rearward mast forklift chassis may include an operator region located behind the fixed mast. The rearward mast forklift chassis may include a forklift device including a forklift positioned in front of the axle of the front wheels pivotally coupled to a tilt swivel and coupled to a tilt cylinder configured such cylinder may extend and/or retract to adjust an angle of the forklift. Various embodiments may advantageously improve efficiency, load stability, weight distribution, and safety.

A vehicle including a propulsion mechanism operable to propel the vehicle for travel thereof; a base coupled to the propulsion mechanism; an upright movably coupled to the base, whereby the upright can be movable upwardly and downwardly relative to the base; and an engagement element movably coupled to the upright, whereby the engagement element can be movable upwardly and downwardly relative to the upright. As to particular embodiments, the inventive vehicle can be configured as a forklift. Following, the engagement element can be configured as a fork having one or more prongs suitable for engaging with a load, whereby the forklift may be useful for lifting and transporting the load from one location to another location.
