Definitions

  • the invention relates more particularly to a lifting and tilting device for a dust cart by means of which dustbins are emptied into a receiver which is closed at the back by a front plate swingable about a horizontal axis, this front plane swinging together with the dustbin into the opening of the receiver during part of the tipping movement. Tipping back, lowering and putting down the empty bin then takes place in reverse sequence of movements.
  • the usual kind of device used on a dust cart for lifting and tilting a dustbin have a swingable arm which is mounted on the housing of the receiver and on which a lifting carriage for the dustbin is mounted to run or slide in the longitudinal direction.
  • These known devices have disadvantages.
  • the guide elements and the guide path on the lifting carriage or its swingable arm are constantly exposed to the risk of considerable soiling when in operation and are therefore found in practice to wear rapidly.
  • the swingable arm must be of length such that it provides a sufliciently long path of guidance for the lifting carriage, with the result thatthereis only a slight ground clearance, i.e. in the position of rest there is only a small vertical distance between the bottom and the ground. This is a disadvantage especially in the case of heavy dust carts because these require a relatively long vertical path for the movement of the springs of the vehicle while on the other hand the swingable arm must extend downwardly so far that even when the dust cart is empty, the lifting carriage must beable to move below the suspension devices on the dustbins.
  • this problem is solved in that the lifting and tilting framework is attached with its guide linkage to the lower part of the swingable arm such that in its upper end position, where its height with respect to the receiver is predetermined by the emptying process which consists in merely tilting it, its rear surface bears against the swingable arm, and the lifting and tilting framework has a lifting device which is independent of the tilting device which acts on the swingable arm.
  • the swingable arm can be relatively short; in practice so short that it no longer projects beyond the lower part of the dustbin as is inevitably the case with the swingable arm of the usual lifting and tilting devices.
  • the ground clearance which depends on the position of the lower end of the swingable arm, is thereby considerably increased, and particularly the risk of accident inherent in the hitherto known devices, due to the part of the arm projecting below the lifted dustbin, is eliminated.
  • the lifting and tilting frame bear-s with itsrear surface against the swingable arm when the dustbin is in the raised position, it provides a very firm, resistant and positive connection between the dustbin and the swingable arm in which there are no hearing or guide elements subject to special wear and 'tear or forceful impacts.
  • the firm connection between the lifting and tilting frame and the swingable arm provides a secure and clearly defined starting position of the lifted dustbin for the tilting movement'whi-ch follows the lifting movement.
  • the contact between the rear of the lifting and tilting frame and the swingable arm also provides a secure and accurate transmission of the tilting movement from the swingable arm to the dustbin without the use of special locking devices, this transmission being ensured during the entire process of swinging the bin into position and swinging it back again.
  • the contact of the rear of the lifting and tilting frame with the swingable arm can be cushioned and thus damped against the transmission of impacts, which was, of course, extremely difi'icult if not impossible in the known moving or sliding guides of a lifting carriage on the swingable arm.
  • the lifting device may comprise 'at least one pneumatically or hydraulically actuated cylinder and piston arrangement which is attached with its top end to 'the swingable arm and its lower end to a
  • this lifting cylinder, or system of lifting cylinders need no longer be adjusted so accurately to the path of movement of a lifting cylinder, and theerfore the means for pivoting the cylinder 'or piston rod can be simpler in construction and more resistant than in the known lifting cylinders for a lifting carriage.
  • the swingable arm itself may advantageously be set back in its lower part, which carries the bearings for the guide linkage, against the upper part which serves as abutment for the lifting and tilting frame.
  • the links thereby always remain within a certain angular range with respect to the swingable arm and the lifting and tilting frame, which ensures that the force of the lifting cylinder of cylinders will act at a suitable angle.
  • the torque exerted on the links by the lifting cylinder results also, in the raised position of the dustbin', in a considerable horizontal component of force with which the lifting and tilting frame is pressed against the swingable ann. This component of force represents the minimum pressure which is further enhanced by the action of gravity on the dustbin when it is swung into position and back.
  • the special design of the swingable arm provides the further advantage that the lifting cylinders arranged at the side .of the arm can extend substantially parallel to it.
  • the swingable arm, the lifting cylinders, the linkages and the lifting and tilting frame thus form a compact unit which is a special advantage in operation.
  • the gripping of the the suspension device of the dustbin by the suspension 1 hooks of the lifting and tilting frame may also be efiected in that the lifting and tilting frame is slightly pressed downwards for that purpose and the suspension devices most part of the movement of the lifting and tilting frame may be inserted into at least one lifting cylinder for this purpose.

  • FIGURE 5 is a detail side elevation of a third embodiment of the invention, showing part of-the swingable arm with the raised lifting and tilting frame in vertical section.
  • the embodiments shown comprise an apparatus for emptying a dustbin 1 into a dust cart, in which the dustbin 1 is first raised from the ground and then emptied by tilting it into a receiver and then swung back from the receiver and put down again on the ground.
  • the I receiver is provided for this purpose withtwo side walls 2 and a front plate 3 which can be swung inwards and which covers the' rear opening of the receiver and is swingable on the lower part of the receiver about a horizontal axis.
  • the apparatus for lifting and tilting the dustbin com- 4 prises a swingable arm 4 which-is mounted bymeans of a fishplate 4b so that it is swingablescoaxially in the front plate 3. Approximately along its lower third, the arm is reduced in thickness, andin its lower part-5 it is set back towards the rear wall of the dust cart or the receiver. part forms the solid continuous'swin'gable arm 4. carries This lower part 5 which together with the upper i two parallel pairs of links 8 and 9 which are arranged above one another and swingably mounted at 6 and 7 frame 12 which is constantly kept by them in a position parallel to the arm 4, at least to the upper part of the arm 4.
  • the lifting and tilting framework 12 comprises a frame or support 13 the length of which is adjusted to the upper part of the swingable arm 4 (see FIGURES 3 and 5).
  • the width of the frame .or support 13 may be slightly greater than-the upper part of the arm 4 and if desired it may be provided with flanges toextend overthe arm.
  • the frame or support 13 may carry a supporting cushion with which it bears against the upper part of the arm 4. It is still more suitable to arrange the cushion 4a on the upper part. ofthe arm 4.
  • the lifting and tilting frame 12 may, like the known lifting carriages, be equipped in its upper part with suspension hooks 15 for the dustbin and below these with a supporting stirrup 16 and at its lower end with an abutment 17 for the. dustbin.
  • the stirrup 16 maybe covered with a slightly harder rubber and the abutment 17 with a softer rubber. It is especially advantageous to provide the abutment 17 with a replaceable three-layered 7 cover in which the lowermost layer is formed by a metal plate, the middle layer by a layer of rubber vulcanised on to the metal plate and the uppermost layer by a soft rubber sheet.
  • la pair of lifting cylinders 18 are provided which are pivoted at their upper end, at 19, to. the swingable arm whilst their piston rods. ar pivoted at 20 approximately at the middle of the lower pair of links 9.
  • the point of contact 20 on the lower. pair of links9 can to a large extent be selected according to the particular requirements.
  • a closure plate 21 Attachedto the upper part of the arm 4 is a closure plate 21 against which the eyelets 22 of the dustbin 1,. which are suspended in the suspension hooks 15, press from below when the lifting and tilting frame 12 is in its uppermost position. This effectivelycloses the suspension hooks 15 and secures the eyelets 22 against slipping out of the hooks 15.
  • the position of rest of the swingable arm 4 and its end position with respect to the backward swinging movement is determined in the usual way by'an abutment buffer 24 on the rear wall of the vehicle.
  • the buffer 23 may be adjustable to compensate for any variation in the level of the apparatus which may be necessitated by the;.par ticular vehicle used.
  • the apparatus operates as followsz'v As shown in FIGURE 2, thedustbin 1 to be emptied is first placed behind the lifting and tilting device.
  • the .main control valve (of any known pneumatic or hydraulic control systemfor' such devices) the pistons of the lifting cylinders 18 are first supplied with pressure fluid from below and thereby the two pairs of links 8 and 9 are pulled upwards orswung, about their pivots 6 and 7 respectively until the frame or support 13 of the lifting and tilting framework 12 bears against the cushioning 4a-on the rear surf-ace of the upper part of the arm 4. Due to the continued pull exerted by the lifting cylinders 18, the lifting and tilting device 12 isheld in firm abutment against the upper part4a of the arm 4.
  • a spring 25 may be inserted into the lower part of at least one of the lifting cylinders 18, as shown in FIG- URE 4, so that the pairs of links 8 and 9 are held in a yielding fashion below their lower end position.
  • the above-described operation of the apparatus is then merely modified by an initial and a final movement by hand, as follows: when the dustbin 1 has been placed behind the lifting and tilting device, the lifting and tilting frame 12 is pressed downwards in the direction of the arrow 26 by means of a handle to be attached to it, and the dustbin is inclined slightly forwardly in the direction of the arrow 27 so that its eyelets 22 are situated above the suspension hooks 15. If the lifting and tilting frame 12 is then released, the suspension hooks 15 are placed into the eyelets 22 from below by the action of the spring 35. The procedure described above can then be continued. When empty dustbin 1 has been put down, the lifting and tilting frame 12 should then be pressed downwards slightly by means of its handle, and the dustbin 1 should be tilted slightly backwards so that the suspension hooks 15 are released from the eyelets 22.
  • the lifting and tilting frame 12 can be held in its raised position with respect to the arm 4 by providing a swingable locking hook 28 on the lower part 5 of the arm 4, which hook fits over a locking bolt or transverse rod 29 of the lower pair of links 9. In normal operation, this locking hook 28 is held in the inoperative position by a spring fitted or other securing means 30.
  • the locking hook 28 may be so designed that in its inoperative position it automatically fits over the bolt or the transverse rod 29 when the links 9 are swung upwards. In such a case, locking can be effected by merely releasing the hook 28 from its holder 30 before the lifting cylinders 18 are put into operation. However, the lifting cylinders 18 must be put under hydraulic pressure to release the locking arrangement, the pressure in the cylinders removing the load on the 6 hook 28 so that the hook can be lifted from the locking bolt or rod 29 and introduced into its holder 30.
  • An apparatus for lifting and tilting containers comprising, in combination:
  • a power-operated lifting means comprising an elongate cylinder :and piston device connected to the arm and to the frame to effect movement of the latter from the lowered to the raised position thereof independently of the pivotal position of the said tilt arm,
  • said cylinder and piston device being disposed substantially in the same plane containing the tilt arm for all pivotal positions of the latter.
  • said linkage means comprising a plurality of link members
  • a spring means is provided in the cylinder of the lifting means, to cushion the lifting and tilting frame in the lower range of its movement.
  • a stop means is provided on the tilt arm, for limiting downward movement of the lifting and tilting frame
  • the tilt arm has a set-back lower portion to which the guide linkage means connects
  • the upper portion of the lifting and tilting frame has hooks for engagement with a projection on the container
  • said tilt arm having a clamp plate on its upper portion for engagement with said container projection when the frame and container carried thereby are in the raised positions.
  • a releasable lock means are provided on the tilt arm, for locking the lifting and tilting frame in its raised position on the arm.
