  • a needle roller bearing 25 acts between the plate 24 and a ring 26 which rests on the plate 9 and which surrounds the swivel 8 circumferentially.
  • An axial bearing 27 rests over the upper part 26A of the ring 26, and bears a support 28 connected to the plate 23.
  • Two slide arrangements 18 disposed at a mutual distance from each other and adapted to the under-frame of a pallet 4 are designed to be operated synchronously with each other, for example by means of a drive coupling 29.
  • a drive arrangement 30 for effecting the extension of the telescopically extensible slide members 20-21 in the desired arbitrary extension direction towards and away from setting-down locations 33-36 for pallets 4 may consist of a plurality of toothed wheels 37 which roll against each other and which are divided into an upper and a lower set of toothed wheels 30A and 30B respectively.
  • the toothed wheels 37 in the upper set 30A are mounted rotatably on the intermediate slide member 20 and co-act at one side with a toothed rack 38 or a similar elongated wheel-engaging running track which is mounted on the top slide member 21, by rolling along the latter, and co-act on the opposite side with a similar toothed rack 39 which is mounted on the base slide member 19.
  • the toothed wheels 37 co-act with a toothed rack 40, etc. mounted on the intermediate slide member 20.
  • the toothed wheels 37 in the set 30B are driven by means of a drive wheel 41 which is connected via a shaft 42 to the drive coupling 29, which may consist of a bevel mitre gear which co-acts with a worm gear 43 connected to a drive motor 44 designed to effect the extension of the outer slide member 21 into the desired position, preferably a piston motor, which is fluid-operated.
  • the base slide member 19 is mounted on the baseplate 23 via a bracket 45 and on the baseplate 23 there is a drive motor 46 which is preferably a fluid-operated piston motor. Via a bevel gearing system 47 the motor 46 is connected to a toothed wheel 48 which is mounted on a shaft 49 and which co-acts with the inside of a toothed ring 50 rigidly connected to the plate 9 of the frame.
  • a drive motor 46 which is preferably a fluid-operated piston motor.
  • a bevel gearing system 47 the motor 46 is connected to a toothed wheel 48 which is mounted on a shaft 49 and which co-acts with the inside of a toothed ring 50 rigidly connected to the plate 9 of the frame.
  • the two drive motors 44.and 46 are connected via supply and return lines 51A, 51B and 52A, 52B respectively to their respective ducts 53-56 which open into the upper end 8A of the swivel 8 and which extend out from the swivel 8 through a top cover plate 57 which is firmly screwed on the swivel 8 and follows the rotary movements of the swivel when the load-moving arrangement 6 is rotated relative to the frame 5.
  • the said ducts 53-56 extend preferably axially through the swivel 8 to their respective channel 58-61 extending peripherally round the circumference of the swivel 8, which are sealed off from each other and surrounded by the said ring 26.
  • supply and return lines 62-65 respectively extend out and are each connected to their respective channel 58-61.
  • the drive arrangement 16 on the lifting column 2 can be connected to the said pressure source, and control valves for effecting supply and draining of fluid to and from the drive motors 15, 44, 46 respectively as desired will also expediently be provided, for example on the lifting column 2.
  • the said peripheral channels 58-61 are designed to communicate with each other in pairs so that one channel of a pair of channels can be connected to the pressure source while the other channel of the said channels can be connected to a slide drive arrangement 44 or 46.
  • Supply of pressure fluid for example into the supply line 62, means that a channel 58 is filled with fluid which flows through the swivel 8 in the duct 53 to the supply line 51A for the motor 46.
  • the gearing 47 is then actuated by the motor 46 to transmit rotary movement to the toothed wheel 48, so that the slide arrangement 6 is rotated around the bearing 8, etc. in a rotary direction over an unlimited distance, since there are no lines which can become twisted and thereby prevent continued rotation.
  • Draining of the fluid via the line 63, the channel 60 the duct 54 and the line 51B from the motor 46 means that the motor 46 is actuated to rotate the slide arrangement 6 in the opposite rotary direction to that described above, into the desired position. This enables the slide arrangement 6 to be rotated unrestrictedly to any of the setting-down locations 33-36, around the bearing 8.
  • Supply of fluid, for example via the line 64, the channel 59, the duct 55 and the line 52A to the motor 44 means that the motor 44 actuates the gearing 29 to rotate in either rotary direction, for example in the direction 66.
  • the larger toothed wheels 37 in the set of wheels 30B is thereby caused to co-act with the toothed rack 40 and drives the rack 40 with the associated intermediate slide member 20 in the direction 67.
  • the larger toothed wheels 37 in the set of wheels 30A are thereby caused to roll away over the toothed rack 39 by the extension of the intermediate slide member, so that the toothed rack 38 with the associated outer slide member moves in the same direction 67 as the intermediate slide member 20.
  • the slide arrangement 6 can be raised by actuation of the motor 15.
  • the invention makes it possible to save space in materials handling, full automation in production is facilitated, the many degrees of freedom provide a considerable selection range in confined spaces, and it is possible to handle all standard types of pallet.
  • the invention is not limited to the embodiment described above, but it may be modified within the frame of the following Patent Claims.
