Definitions

  • the invention relates to a lifting device for lifting and lowering freight containers, swap bodies or the like of trucks.
  • a corner fitting is a hollow body formed of strong, flat steel sheet surfaces, wherein individual ones of these surfaces have an opening with the cross-sectional area of a flat oval.
  • the usual latch for a corner fitting is often referred to as a "twist lock”.
  • the bolt is inserted through this part of the bolt with a frontal, hammerhead-like widening through an opening on a surface of the corner fitting and rotated about its longitudinal axis by 90 °.
  • the principle is including a meaningful development in addition to the AT 392 047 B shown.
  • lifting devices are used, one of which is docked to the corner fittings of the container.
  • the lifting devices first lift the container so far that the load vehicle passing underneath can drive away; then the container is lowered by the synchronized moving lifting devices to the ground.
  • the lifting devices have to telescopically movable into one another hollow sections, which are normally driven by an internally disposed hydraulic cylinder relative to each other movable.
  • a disadvantage of this method of attachment of the diagonal strut to the connector is that the process of attachment is difficult to perform. Alone by the arm of the person performing the already relatively heavy diagonal strut in an elevated position must be moved very accurately, as in the region of its longitudinal center horizontally projecting bolt must be inserted into a horizontal bore on the connector from the side of the container. Another disadvantage is that the diagonal brace can easily fall to the ground with little clumsiness while handling the connector - which is not only annoying, but also quite a risk of injury.
  • a third disadvantage is that the support of the diagonal strut on the connecting part against pivoting movements in planes which are normal to the adjacent container wall, is only very little stable.
  • the main task underlying the invention is to make the releasable attachment between diagonal strut and connector so that it can be closed without great difficulty and without great skill. Another object is that unwanted falling down of the diagonal brace during the attachment process to be able to exclude as far as possible at the arranged on the container connection part.
  • a third task is to fix the diagonal strut on the connecting part more stable against relative pivotal movement in all lying normal to the adjacent container wall levels than is the case according to the prior art.
  • connection part 2 As in Fig. 1 clearly visible, bridges the multi-part diagonal strut 3 with its main profile 3.1, the angle between the lateral horizontal lower frame profile and the vertical frame profile of the corner of the container 4 to which the corner fitting 4.1 is attached.
  • the main profile 3.1 and the connection part 2 cross each other.
  • the main profile 3.1 rests on a support part 2.1 of the connection part 2.
  • the connection part of the support part 2.1 extends not only on the side facing away from the container of the lateral surface of the main profile 3.1 up, but also with a wall 2.3 on the side facing the container side of the lateral surface.
  • the main profile 3.1 is held on the support part 2.1 of the connection part not only against downward movement, but also against slipping normal to the container wall.
  • the flank 3.3 with which the diagonal brace 3 rests on the support part 2.1 of the connection part 2, is formed in the present example by a main section 3.1 of the diagonal brace 3 attached bearing part 3.5 and the front-side connecting part 3.2.1 to a side profile 3.2 of the diagonal brace.
  • the flank 3.3 is aligned in the manner described above. Alone by such aligned, from the lower surface of the main profile protruding edge is already achieved that after the diagonal strut was placed with its lower longitudinal portion on the support part 2.1 during assembly, this can only slip up to the edge of 3.5 and then on Pad part is only more pivotally movable. Holding against this turning requires little power and no skill.
  • the attachment of the diagonal strut on the support part 2.1 of the connecting part 2 is also improved so that a backup against lifting of the diagonal strut is formed upwards.
  • the support part 2.1 is formed as a circular cylindrical pin with the container wall normal orientation.
  • a bearing part 3.5 is rigidly fixed to this pivotally a connecting part 3.2.1 is attached, which is rigidly connected to the front side of a secondary profile 3.2 of the diagonal strut.
  • the pivot axis is after fully assembled diagonal strut at least approximately normal to the adjacent container wall.
  • the secondary profile 3.2 is thus pivotal from a storage position in which it rests on the upper part of the main profile 3.1 in an "operating position". In “operating position” it runs approximately from the support part 2.1 at the opposite side of the lower section of the main profile side of the connecting part 2 obliquely down to the lower edge of the container.
  • the lower longitudinal region of the main profile 3.1 facing edge 3.3 of the pivotally mounted on the bearing part 3.5 to the main profile 3.1 3.1.1 3.2.1 extends down to the support part 2.1 diagonal brace with a portion 3.3.1 down as the cross-sectional area of the bolt, which the support part 2.1 of the connection part forms.
  • the flank area 3.3.1 is slightly inclined in the pivoting plane relative to the radius line to its pivot axis in such a way that further outward areas are further forward in the pivoting movement of the sub-profile 3.2 of the storage position in the operating position.
  • the bearing part 3.5 has a projecting from the lower surface of the lateral surface of the main profile 3.1 extension, which has a the upper longitudinal part of the main profile facing edge 3.5.1, which together with the edge 3.3 adjacent to the main profile 3.1 side profile 3.1 in the direction parallel to the pivot axis of the secondary profile 3.1 limit a downwardly open V-shaped cutout.
  • the bracket of the diagonal brace can also be explained so that the flanks 3.5.1 and 3.1.1 together narrow a forceps jaw, which is when pivoting the side strut 3.2 in the operating position to the bolt, which forms the support member 2.1 on the connection part, closes.
  • each one of a vertical and a horizontal leg existing bracket 3.4 is fixed, which can engage under a lower boundary surface 4.2 of the lower longitudinal profile of the container.
  • the pivot axes of the bracket are at least approximately parallel to the pivot axis of the secondary profile on the main profile.
  • a second support strut 3.6 extends - also pivotally fixed at both ends - between a point just above the lower end of the auxiliary profile located in the operating position 3.2 and tabs 2.2 on the side profile facing the side of the connection part.
  • the tabs 2.2 which form the fastening point on the connection part 2, are further away from the container wall than the attachment point of the support struts to the diagonal struts.
  • the tabs 2.2 are further with a considerable vertical distance below the support part 2.1. This ensures that the pressure force of the support struts 3.6 causes a force of the mounting bracket 3.5, which has a horizontally acting on the container 4 component and a vertically upward component.
  • the lateral boundary surface of the corner fitting 4.1 that is, the surface on which the connection part 2 abuts via the so-called twistlock connection, is often slightly overhangingly inclined in some designs.
  • the lateral boundary surface of the corner fitting 4.1 that is, the surface on which the connection part 2 abuts via the so-called twistlock connection, is often slightly overhangingly inclined in some designs.
  • the latch 5 is usually formed as a twistlock latch.
  • the support screws 6 are aligned parallel to the latch 5. They are each with a threaded bore 2.5 in the corner fitting 4.1 facing surface of the connecting part 2 into engagement.
  • the connection part facing surface of the corner fitting 4.1 has at the point where the end face of the support screw 6 meets him, no breakthrough; ie after the support screws are screwed through the threaded hole 2.5 in the connection part 2, they press on further screws connector and corner fitting away from each other. Since these are held together on the bolt 5, they are pivoted against each other.
