Definitions

  • the invention relates to a lifting arrangement and a lifting method.
  • a lifting device In connection with a lorry, for example, a lifting device is used, by means of which the lorry's load is moved onto the bed and off the bed. The lifting device is moved with the lorry's hoist.
  • the lifting device may have forks which are utilised when handling cargo pallets, for example.
  • the lifting arrangement features a lifting device which may be hooked up to a hoist.
  • the lifting device comprises a frame, forks as a lifting member and a quick clamp. With the quick clamp, the forks may be attached to the frame of the lifting device and detached from the frame of the lifting device.
  • the lifting arrangement has at least one further lifting member, this at least one further lifting member also being attachable to the frame of the lifting device and detachable from the frame of the lifting device with the quick clamp in question.
  • the lifting device may be used to handle various pieces and products without any need to make modifications to the hoist or the frame of the lifting device, or to use a different kind of hoist or lifting device for the handling.
  • the at least one further lifting member may be one or more of the following: a bucket, grab, claws, or round bale claws.
  • the quick clamp is fixedly attached to the frame of the lifting device.
  • the quick clamp may be attached to a lower part of the frame of the lifting device, and the lower part of the frame is removably fixed to another part of the frame and turnable in relation to the other part of the frame.
  • the frame of the lifting device may have a top part, oriented obliquely upwards, and the quick clamp may be oriented in the same direction as the top part of the frame when forks, for example, have been attached to the quick clamp. In such a case, the lifting device stays well balanced.
  • a bottom part of the frame may be turned in the opposite direction, in relation to the aforementioned, whereby it is easy to grasp an item from above with the grab or claws.
  • a lifting device 1 is shown.
  • the lifting device 1 has a frame 2, forks 3, and a quick clamp 4.
  • the forks 3 are one example of lifting members of the disclosed lifting device 1.
  • the forks 3 may be attached to the frame 2 of the lifting device 1 and may also be detached from the frame 2 of the lifting device 1 by means of the quick clamp 4.
  • the quick clamp 4 may be fixedly attached to the frame 2 of the lifting device 1.
  • the forks 3 or another lifting member may be detachably hooked up to the frame 2 of the lifting device 1 without using a hammer or another tool.
  • the quick clamp 4 allows an easy and fast attachment and detachment of forks 3 or another lifting member to and from the frame 2 of the lifting device 1.
  • the quick clamp 4 may also be referred to as a quick coupler.
  • the frame 2 has a frame top part 2a and a frame bottom part 2b.
  • the frame top part 2a has a portion oriented obliquely upwards, and a portion oriented downwards.
  • the portion of the frame top part 2a oriented obliquely upwards may be, for example, 500 to 1000 mm long.
  • the total height of the lifting device may be 1000 to 2000 mm, for example.
  • the lifting loop 5 acts as a coupling member to hook up the lifting device 1 to the hoist.
  • the lifting loop 5 or another coupling member may also be adapted in the vicinity of a corner in the frame top part 2a, for example.
  • the lifting loop 5 or another coupling member may also be stepwise or slidingly moved in relation to the frame top part 2a.
  • the frame bottom part 2b is fixed to the downward oriented part of the frame top part 2a.
  • the frame bottom part 2b and the frame top part 2a may be connected to each other so that the parts are easy to detach from each other.
  • the downward oriented part of the frame top part 2a and the frame bottom part 2b may be tubular parts, for example, adapted one inside another.
  • the tubular parts may be provided with holes, for example, through which a locking peg or locking pin may be adapted to interlock the tubular parts.
  • the tubular parts may be round or angular, such as square.
  • the part to be fitted as the inner part may be a solid bar instead of having a tubular structure.
  • the quick clamp 4 is located on the frame 2 so that it is oriented towards the obliquely upwards oriented part of the frame top part 2a.
  • the lifting device 1 when being lifted by the hoist, stays controllably balanced.
  • Figure 2 shows a situation where the forks 3 are removed from the frame 2.
  • another lifting member may be put in their place.
  • This another lifting member may be a conventional bucket, a four-action bucket, grab, claws, or round pale claws.
  • the frame bottom part 2b may be disconnected from the frame top part 2a. After detachment, the frame bottom part 2b may further be turned in relation to the frame top part 2a.
  • the quick clamp 4 can be installed so that, for example, it is oriented away from the obliquely upwards pointing part of the frame top part 2a. Thereby a grab or claws may be connected to the quick clamp 4. Consequently, it is easy to grab a large piece from above by means of the lifting member.
  • hydraulic hoses may be adapted in connection with the frame 2.
  • the lifting device 1 may thus be used to operate lifting members requiring hydraulics.
  • the hydraulic hoses may be attached to hose brackets adapted in connection with the frame bottom part 2b, for example.
  • the hoist may be a stationary hoist or a hoist adapted in connection with a vehicle.
  • Figure 3 shows a vehicle 6, such as a lorry, having a hoist 7 connected to it.
  • an accessories box or enclosure 8 may be adapted, where various lifting members may be placed. So, the lifting members can be stored in connection with the vehicle 6, and they can be transported with the vehicle 6.
  • the lifting arrangement can therefore be used in diverse manners without the need to make changes in advance to the lifting device or lifting members used in connection with it.
  • the accessories enclosure 8 is adapted below a cargo space 9, such as a bed.
  • the accessories enclosure 8 forms a fixed and safe storage solution, separate from the cargo space 9, for the accessories needed for loading, lifting, and/or binding, for example.
  • the hoist 7, for its part, is adapted between the cargo space 9 and a cabin 10 of the vehicle 6.
  • the structure of the accessories enclosure 8 are seen in closer detail in Figures 4, 5, and 6 .
  • the accessories enclosure 8 has two storage tubes 11. At their first ends, the storage tubes 11 are fixed to a support 12 by welding, for example. At their second ends, the storage tubes 11 may be open. In such a case, the lifting parts of the forks 3, for example, may be inserted inside the storage tubes 11 to store and transport the forks.
  • Figures 4 and 5 illustrate that a lifting device, for example, from which a lifting member has been removed, so the frame 2 of the lifting member and the quick release 4 therein may be adapted in the accessories enclosure 8 on top of the storage tubes 11.
  • the support 12 is adapted around a pivot pin 13. By its top end, the pivot pin 13 is fixed to a top plate 14 and, by its bottom end, to a bottom plate 15. The top plate 14 and bottom plate 15 are fixed to a fastening plate 16.
  • the accessories enclosure 8 is fixed to the body of the vehicle 6 by means of the fastening plate 16.
  • the fastenings may be carried out by welding, riveting, bolt/nut fastening, and/or another appropriate fastening manner.
  • the storage tubes 11 and support 12 may be turned around the joint 13a formed by the pivot pin 13, as illustrated in Figure 5 by the arrow A.
  • the storage tubes 11 may be turned in the longitudinal direction of the body of the vehicle 6 and locked in place. This position may also be referred to as the transportation position.
  • the accessories enclosure 8 is, for example, turned transverse in relation to the vehicle 6 body and locked in place. This position may also be referred to as the usage position.
  • the accessories are then easy to take out of the accessories enclosure and use them. Once the accessories have been put into use, the accessories enclosure 8 may be turned back in the direction of the vehicle 6 body for the time they are being used. After use, operation is naturally the reverse.
  • pivot pin 13 and joint 13a In the attached drawings, the location of the pivot pin 13 and joint 13a are shown as reference, only. The pivot pin 13 and joint 13a may be located closer to the fastening plate 16 than shown in the attached drawings. The closer to the fastening plate 16 the pivot pin 13 and joint 13a are located, the less twisting and other stress will be conveyed to the structures, such as the top plate 14, bottom plate 15, and fastening plate 16. Thus, the structures may be formed simpler and lighter.
  • the accessories enclosure 8 is longitudinal, so the storage tubes 11 are longer than the total width of the accessories enclosure 8.
  • the accessories enclosure 8 may also be formed without a tubular structure, that is, the accessories enclosure 8 may be box-like. Even then, the accessories enclosure 8 may be longitudinal and in the transportation position adapted to be parallel to the longitudinal direction of the vehicle 6 body.
  • the forks 3 and/or lifting device When, for example, the forks 3 and/or lifting device is adapted in the accessories enclosure 8, as shown in Figure 4 , and the accessories enclosure 8 turned in the longitudinal direction of the body 6 to the transportation position, the part of the forks 3 on the quick clamp 4 side and/or top part 2a of the body 2 of the lifting device may extend into the space between the cargo space 9 and cabin 10. They may thus be side-by-side with the hoist 7.
  • the accessories enclosure 8 disclosed may be used to store and transport any accessory.
  • the lifting device stored and transported in the transportation enclosure need not be provided with a quick clamp or detachable lifting members.
  • the lifting device may therefore be a conventional lifting device that may have, for example, a fixed lifting member.
