A maintenance apparatus, in particular for lifting and moving components of a system for processing semiconductor devices. The apparatus comprises a beam and an arm with means for lifting a component, the arm being mounted to the beam via a connecting unit and so as to be pivotable in a horizontal plane, wherein the connecting unit is displaceable along the beam, and wherein the arm is displaceable perpendicularly to the beam, and wherein a load accommodation means is provided on the pivotable arm.

The present invention involves a narrow aisle truck comprising: a vehicle body having length and width directions; wheels assigned to the vehicle body and arranged on two axes running in the width direction and configured to drive and steer the truck; a drive system configured to exert an acceleration torque on at least one of the wheels; a mast extending substantially vertically with respect to the length direction of the vehicle body between the two axes; at least one detection unit to detect at least one state parameter; at least one actuator to cause a movement of the mast relative to the vehicle body; and a control unit to: determine a current state, determine an effect of an actuation of the at least one actuator on the current state, and activate the at least one actuator to reduce a difference between the determined current state and a predetermined target state.

A forklift includes a vehicle body, a fork having a distal end extending in a first direction of a first axis, a mast extending along a second axis intersecting the first axis and holding a proximal end of the fork such that the fork is configured to slide along the second axis, and a first sliding mechanism configured to cause the mast to slide along the first axis such that the distal end of the fork protrudes from the vehicle body.

An adjustable load handler configured to be mounted on lift trucks with different standard type carriages. The handler comprising a frame assembly, a top hook assembly with a securing mechanism for securing the top hook assembly to the frame assembly in a plurality of positions A center manifold is coupled to the underside of the side shift actuator, with hydraulic connections directly into the side shift actuator. Hydraulic lines coupled to the center manifold and to one or more hydraulic components of the loader have sufficient slack so the top hook assembly can be moved between positions without disconnecting any of these hydraulic lines.

A powered forklift assembly is configured to be operably mounted on an over-the-road vehicle to shift a load relative to a chassis of the vehicle. The powered forklift assembly includes a shiftable forklift and a vehicle bed. The shiftable forklift includes an extendable mast and a fork mechanism. The fork mechanism is attached to and is vertically shiftable relative to the mast and configured to support the load.

An industrial vehicle comprising a tag reader, a reader module, and a diagnostic tag, wherein the diagnostic tag is coupled to the industrial truck within a read range of the tag reader. The reader module and the tag reader cooperate to identify the diagnostic tag and individual tags of a tag layout and the reader module discriminates between the individual tags of the tag layout and the diagnostic tag and the individual tags of the tag layout, correlates an identified individual tag of the tag layout with tag data, correlates an identified diagnostic tag with operation of the tag reader, and generates a missing tag signal if the diagnostic tag is not identified or the operation of the tag reader is not within specified operating parameters.

A forklift includes a vehicle and a cargo handling device. The cargo handling device includes a mast, a lift bracket, and a pair of forks that includes claw portions, the forks being separated from each other in a vehicle width direction. The vehicle includes a vehicle main body, and a pair of straddle legs that is provided such that the straddle legs extend to the front side from a lower portion of the vehicle main body and the cargo handling device is interposed between the straddle legs in the vehicle width direction and that supports the mast such that the cargo handling device is movable forward and backward between an advance position and a retreat position, and front ends of the claw portions are positioned behind front ends of the straddle legs when the cargo handling device is at the retreat position.
