Abstract: Add-on device (1) to be attached to a lifting vehicle, having a movable fork arm unit (2) comprising at least one fork arm (3), having at least two units (4) for driving a lateral movement of the fork arm unit (2), in particular each comprising at least one drive chain (6), in particular running in opposite directions, wherein the drive chain (6) is in particular assigned to a respective fork arm (3), having in each case at least one hydraulic motor (11), by which the unit can be driven, wherein the hydraulic motors (11) of two units (4) can be connected in parallel for a lateral movement of the fork arms (3) in the same direction and/or the hydraulic motors (11) of two units (4) can be connected in series for a lateral movement of the fork arms (3) in opposite directions. Method for actuating said add-on device (1).

Abstract: Apparatus for transport of a transport item for arranging at a lifting vehicle, especially at a transportation unit of a fork lifter, especially of a commissioning package, especially with a load lower than about 50 kg, comprising a means for at least temporarily picking up of the transport item by a vacuum means and/or a transportation belt, whereas the vacuum means is to be attached to the transport item essentially in the horizontal, and/or the transportation belt at a lower edge of the transport item, whereas the vacuum means and/or the transportation belt is attached to an pivot arm with a pivot point, which allows a handling of the transport item with the vacuum means and/or the transportation belt, especially a pivoting, especially in a defined pivoting angle, especially about +/?90°, in the horizontal, and/or allows dropping of the transport item, especially in the horizontal.

Abstract: Attachments for floor and yard trucks with a lift mast, especially for fork lift trucks, have a lift carriage (8) which has two side plates (9, 10) and two horizontal beams (12/14, 13) situated one over the other with a clearance (“h”) between them, on which there is held at least one hydraulically powered element from the group: load carrier, “transport securing means,” rotating device, tilting device, pushing device, pulling device, holding device, lifting device, fork shifting device, lateral shift frame (1), each with the corresponding hydraulic drive (14). The front sides of the horizontal beams (12/14, 13) and the rear edges of the side plates (9, 10) of the lift carriage (8) are disposed between two vertical planes defining between them a space (7) wherein the at least one hydraulic jack (14) is arranged and the corresponding control unit (18) is disposed.

Abstract: Disclosed is a lateral shifting system for a floor transport vehicle, which has a lift carriage with a base frame with one upper and one lower hook edge for mounting fork tines and has a lateral shift frame. The lateral shift frame has two horizontal frame members with, on the one hand, cross sections which grasp the edges of the base frame and on the other hand form edges for fork tines, and a double-acting hydraulic driver for shifting the lateral shift frame. To reduce weight, tolerances and difficulty in assembly, the lower horizontal frame member can be swung in back of the bottom edge of the base frame by means of an uptumed cross-sectional extremity, and for a sliding, form-fitting combination of base frame and lateral shift frame, U-shaped antifriction bearings are inserted from the side between the lower edge of the base frame and the lower horizontal member of the lateral shift frame.

Abstract: A support with a through-hole (13) for a plunger (3) and a contact surface (15) for a sealing ring (8), is designed as a sliding body (12) with two .diametrically opposite sliding shoulders, which are inserted in complementary transverse grooves (9, 10) in the end of a cylinder (1). After the sliding body (12) has been inserted, it is held in place in the cylinder by the plunger (3). The sliding body (12) is provided with an annular channel inside the through-hole, in which channel a wiper ring (17) is set.

Abstract: Carrying device for a container with four supporting journals which, by means of a hydraulic actuating device 18, 21, can be locked or unlocked and respectively or with a hydraulic device 8, 9, 10, 11 for the change of the span width. A pumping device 23, 24, 25, 26 which can be actuated by means of a cable line is provided on the carrying device so that, also in the case in which the carrying device is attached to a crane without a pressure medium source, the hydraulic actuating device 18, 21 can be operated for locking and unlocking purposes, and respectively or the hydraulic device 8, 9, 10, 11 can be operated for the purpose of changing the span width.

Abstract: A load carrying arrangement for a lift truck includes two spaced apart hollow upright elongated members which are mounted on a mounting element that is displaceably mounted on the frame of the truck, and at least one load-engaging attachment which has at least one load-engaging portion and two mounting portions introducible into the interiors of the corresponding upright members through the open ends thereof to mount the load-engaging attachment on the upright members and thus on the mounting element. Fixing elements, such as pins or bolts extending through aligned bores in the upright members and in the mounting portions, positionally fix the mounting portions within the corresponding upright members.
