In accordance with one embodiment of the present invention, a side loading attachment (40) for use with a forklift truck (70) having a pair of forwardly extended forklift forks (70F). The attachment (40) comprises a pair of hollow sleeves (42) to receive the forklift forks (70F). A support frame (41) is welded to the hollow sleeves (42). A sliding bracket (43) is slidably mounted to the support frame (41). A rotatable shaft (45) is rotatably mounted to the sliding bracket (43). A tiltable frame (44) is pivotally mounted to the rotatable shaft (45). An elevating carriage (46) is slidably mounted to the tiltable frame (44). A pair of load forks (40F) are mounted to the elevating carriage (46) whereby the load forks (40F) can be rotated and shifted to either side of the forklift truck (70) and can be elevated and tilted to deposit or retrieve a palletized load (30) to either side of the forklift truck (70) in a narrow aisle operation.

A swivel base is provided on a trolley so as to be able to swivel around a vertical axis, and a fork can be slid in a horizontal direction between an advanced position and a retracted position by a sliding mechanism capable of moving up and down along a pillar erected on the swivel base. Thus, it is possible to realize a configuration in which an empty-box skid is loaded in one direction and unloaded in another direction by means of the swiveling swivel base, without employing a configuration in which a plurality of members is supported so as to be able to swivel around different vertical axes. A movable range of the sliding mechanism (a movable range of the fork) in a vertical direction is therefore not significantly limited, and a transfer position of the empty-box skid in the vertical direction can be set to a lower position.

An industrial truck is described, such as a tri-lateral sideloader, comprising a truck body, wheels connected to the truck body by wheel suspensions, a mast, a plurality of operating components designed to carry out operating functions of the industrial truck, a control unit designed to actuate the operating components, and a detection apparatus designed to detect an operating parameter and/or a parameter of the environment. Here, the industrial truck further comprises a prediction unit designed to predict the occurrence of vibrations on the industrial truck based on data provided by the detection apparatus and to provide prediction data to the control unit. Based on the prediction data, the control unit is further designed to adapt the actuation of at least one of the operating components and/or to actuate an apparatus for reducing vibrations such that the vibrations predicted by the prediction unit are reduced.

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 guide-roll arrangement for guiding movement of a first member relative a second member of a lift-truck, comprising a roll pin having opposing first and second ends, wherein the first end comprises a recess; and a roll supported on the roll pin; and a sliding element arranged in the recess, said sliding element comprising opposing contact and sliding surfaces, wherein a support piece is arranged in the recess and comprising a contact surface for supporting the sliding element, wherein the contact surface of the sliding element is supported on the contact surface of the support piece and wherein one of the contact surfaces of the support piece and the sliding element is concave and the other is convex.

A loading frame includes a rectangular u-shaped frame with an opening at one side, forks extendable and retractable between the closed side and the open side of the U-shaped frame, loading frame wheels on one arm of the U-shaped frame, and a truck interface on the other arm of the U-shaped frame. The loading frame wheels and truck interface support travel of the frame in a direction other than the direction of travel of the forks between the open and closed sides of the U-shaped frame.
