Definitions

  • the invention relates to a lifting device for receiving, lifting and / or transporting loads with at least one support arm projecting in an approximately horizontal direction from a height-adjustable lifting frame, the fastening of the supporting arm to the lifting frame via at least one hook-like projecting hanging part and at least one horizontally projecting bolts and openings, slots or the like provided on the opposite part.
  • a forklift attachment is provided on a height-adjustable lifting frame, the centering being carried out by two bolt-like approaches.
  • the attached additional device is fixed with locking hooks.
  • Corresponding support arms are pivotally and displaceably attached to this additional device.
  • a special additional frame is therefore required here, so that an enormous amount of mechanical effort is required to attach the two support arms to the lifting frame. If support arms in a different arrangement or other support arms are to be arranged here, larger assembly work is required or several such additional devices must be available for different areas of application, but which remove one.
  • the locking hooks which form the actual locking mechanism are merely by their own weight include the lifting frame.
  • the arrangement of corresponding springs would also be conceivable, but then additional mechanical parts are then present.
  • the invention has therefore set itself the task of creating a structurally very simple connection between a support arm and the corresponding lifting frame.
  • Lxird proposes that at the end of the support arm facing the lifting frame a support plate is provided which projects perpendicularly to the support arm at right angles to the longitudinal extent thereof, with a section of the lift frame facing the contact plate facing the support plate or at the upper free edge thereof
  • Contact plate a this contact plate on the boundary facing away from the support arm, protruding from an L-shaped profile and a lower part of the contact plate or the lifting frame assigned a pin projecting in the same direction are provided, and on the contact plate or on the the abutment plate facing section of the lifting frame slots, openings or the like. Are provided for receiving the hanging part and the bolt.
  • each individual support arm can be held in the desired position by hanging and corresponding centering, so that no special additional connections in the form of screws or the like are required.
  • different support arms can be used, especially since the replacement and again attach another support arm can go in a very simple manner.
  • such an interchangeable arrangement makes it possible to provide different suspension variants, in order to enable different settings for different shapes or types of the loads to be taken up.
  • Such a construction means that the material required for the support arms is very low. In addition, this also makes storage of various support arms very easy, since they require only a small amount of space.
  • an unwanted loosening of the connection is not possible, since in order to loosen the support arm it would have to be raised at its free, projecting end and would also have to be pulled out in its longitudinal direction.
  • the bolt provided on the support arm or on the lifting frame not only centers the special position of the support arm, but also creates a safeguard against unhooking of the hanging part.
  • FIG. 1 shows a side view of a lifting device
  • Fig. 2 is a front view of the same
  • 3 is a partial front view of a height-adjustable lifting frame of the lifting device
  • 4 shows an enlarged detail from the lifting frame
  • 5 shows a section along the line I - I in FIG. 4.
  • the lifting device 1 is only given as an example, since it can of course be provided in different design variants. It is, for example, one equipped with roles Lifting device that can be moved to the appropriate location by a worker.
  • the lifting frame 2 is raised hydraulically, pneumatically, electrically or also mechanically. Of course, the same arrangement can also be used with motor-driven lifting devices or also with any type of lifting devices which somehow have support arms.
  • support arms 3 are provided in the lifting device, which are each arranged at the end regions with respect to the horizontal extension of the lifting frame 2. These support arms 3 are detachably connected to the lifting frame 2, for which purpose corresponding hooking and centering means are provided on the supporting arms 3 or the adjustable lifting frame 2.
  • hooking and centering means are provided in the mutual contact area between a support arm 3 and the lifting frame 2, the hooking part 4 projecting like a hook and an additional, approximately horiozntal projecting bolt 5 ensures centering of the support arm.
  • Slots 6 and openings 7 are provided on the correspondingly opposite part.
  • a support plate 8 projecting above the support arm 3 at right angles to the longitudinal extension thereof.
  • the hanging part 4 is fastened, which is formed from an approximately L-shaped profile.
  • a pin 5 projecting in the same direction as the hanging part 4 is inserted. Then in the lifting frame 2 the opening 7 corresponding to the bolt and the slot 6 designed to insert the hanging part 4 are provided.
  • the support arm can be very easily attached to the lifting frame 2 and in turn removed, a corresponding fixation being nevertheless ensured in its position of use.
  • the suspension part 4 is initially inserted into the slot 6, whereby the upwardly projecting part 9 of the suspension part engages behind the edge limitation of the slot 6 by moving the support arm upwards, the bolt 5 only in this position of use in the Opening 7 can be inserted.
  • the width of the slot 6 is made the same or slightly larger than the height of the L-shaped hanging part 4. It must also be taken into account here that the insertion must take place in a certain inclined position, since the bolt 5 can only engage in the opening 7 after the insertion of the hanging part 4.
  • the hanging part 4 and the bolt 5 are expediently arranged symmetrically with respect to the plane of symmetry of the support arm, which has an effect in particular through the favorable absorption of the load.
  • the forces acting on a support arm will also always run essentially in the direction of the central plane of symmetry thereof.
  • openings 7 and slots 6 are provided at both end regions, so that two support arms 3 can be attached at a corresponding distance from one another.
  • two or more slots 6 and openings 7 arranged offset from one another are provided at the end regions of the lifting frame 2.
  • the support arms 3 can therefore be hung more or less far apart from one another on the lifting frame.
  • the slots 6 run obliquely to the horizontal, a plane passing through the centers of the slot 6 and the opening 7 representing their common plane of symmetry.
  • the slots enclose an angle of approximately 45 degrees to the horizontal.
  • the support arms 3 can correspond in cross-section to a right-angled, isosceles triangle, the hypotenuse-side boundary surface 10 running parallel to the longitudinal extent of the hanging part 4 and at the same time forming the support surface of the support arm 3.
  • reinforcement strips 11 or reinforcement profiles are fastened, preferably welded, in the area of the slots C.
  • the hanging part 4 and the bolt 5 on the support arm 3 and the slots 6 and the openings 7 are arranged on the lifting frame 2.
  • these parts are interchangeable with each other, so that, for example, the hanging part 4 and the bolt 5 are attached to the lifting frame 2 and a slot 6 and an opening 7 on the support arm 3.
  • a partial change is also possible, for example by attaching the hanging part 4 to the support arm 3 and the bolt 5 to the lifting frame 2, in which case the slot 6 on the lifting frame 2 and the opening 7 on the support arm 3 are provided.
  • the cross section of the bolt 5 can of course be designed in various ways, which of course can also be designed as a rectangular plate part. All other cross-sectional shapes are also conceivable.
  • the arrangement of a hanging part 4 and a bolt 5 is essential and important, the use of the bolt 5 practically securing the operating position of the hanging part 4.
