Definitions

  • the present invention relates to a method and an arrangement pertaining to side-lift yokes for hanling mutually stacked empty containers from the sides thereof.
  • the side-lift yokes used to handle two mutually stacked containers comprise, in principle, a horizontal frame which includes vertical carrier beams at respective ends thereof. Mounted centrally of the frame is a truck-lift coupling that can be lenthened or shortened in accordance with the container length.
  • Respective carrier beams include support surfaces which are brought into engagement with the container sides, and a top-mounted locking hook for insertion into the upper locking opening of the bottom container.
  • the two containers can thus be lifted and transported with the aid of a truck-lift through the medium of the side-lift yokes.
  • the document EP 0 638 512 which is state of the art according to Art 54(3) EPC, shows a carrying device for picking up two containers placed on top of the other.
  • the containers may have shifted in a direction transversely to the side surfaces provided with the holes 6 into which the insert ends 25 and 21 are inserted.
  • Such a displacement may be set off by pivoting of the coupling arm 19 about the pivot pin 20, whereby the coupling means 16 and 23 can slightly move in a direction perpendicularly to the surfaces of the containers provided with the openings into which the insert ends must be inserted.
  • FIGs 9 and 10 such a movement of the coupling means 16 and 23 is limited by stops 26 and 27 cooperating with the coupling arm 19. (Fig. 9 and 10).
  • An object of the present invention is to facilitate the handling of two mutually stacked empty containers and to shorten container handling times. This object is achieved by means of the method of claim 1 and of the side-lift yoke of claim 2.
  • Fig. 1 illustrates a known side-lift yoke which includes an inventive arrangement
  • Fig. 2 s a side view of the side-lift yoke
  • Fig. 3 is a more detailed view of the inventive arrangement and shows the arrangement in a movement phase
  • Fig. 4 illustrates the inventive arrangement in another movement phase
  • Fig. 5 illustrates the twist-lock principle by way of explanation only.
  • Fig. 1 thus illustrates a known side-lift yoke comprised of a horizontal frame 1 and a lifting device 2 which is located in the centre of the frame and which is used to couple the yoke to an automative vehicle, such as a truck or the like.
  • the yoke further comprises vertical carrier beams 4 which are mounted on the ends of beams 3, these beams being telescopically movable in the frame 1.
  • Each carrier beam 4 includes a respective upper and lower support surface 5 which are intended to abut the longitudinal sides of the container when locking the side-lift yoke.
  • the side-lift yoke is also provided with a locking device 6 at the top of each carrier beam 3, this locking device being described below in more detail with reference to the actual invention.
  • the side-lift yoke as such is known to the art and will include a suitable hydraulic system among things, and will not therefore be described in more detail here.
  • the inventive locking device is shown in more detail in Figs. 3 and 4.
  • the reference numeral 7 in Figs. 3 and 4 identifies the upper corner of a corner-reinforced lower container and the bottom corner of a corner-reinforced upper container which rests on the lower container.
  • the inventive locking device comprises two mutually independent and horizontally movable cylindrical locking bolts 8, each having a head 9 which is elongated when seen in cross-section of the bolt. Respective locking bolts 8 are moved horizontally by means of a hydraulic cylinder 10, which is connected to the locking bolt 8 with the aid of a piston and piston rod 11. Respective locking bolts 8 can also be twisted through 90° with the aid of a hydraulic cylinder which includes a piston and piston rod, together referenced 12.
  • This piston rod is mounted excentrically at the inner end of the locking bolt 8, and functions to twist the bolt through 90° as aforementioned.
  • the hydraulic cylinder 12 is connected to a bracket 13 which is connected to the locking bolt 8 and which together with the hydraulic cylinder 12 is operative in moving the bolt 8 when said bolt is manoeuvered by the hydraulic cylinder 10.
  • the locking bolt 8 with its undercut, elongated head 9 forms what is generally known in the art as a "twist-lock”.
  • the corner reinforcements at respective corners of each container include elongated locking openings 14 on each upper side of each container.
  • Fig. 5 illustrates one such locking opening in a container 7 schematically and shows a locking bolt 8 and its head 9 inserted in the opening.
  • the elongated head and its opening-adapted shape enables the head to be inserted into the locking opening 14.
  • the locking bolt When the locking bolt is twisted, the head will grip behind the defining edges of the locking opening 14 and therewith lock the bolt to the container, and in the illustrated case lock the container to the side-lift yoke.
  • Fig. 3 shows a lower container 7 and an upper container 7 which rests on top of the lower container 7 and which when stacking the containers has been placed out of longitudinal alignment and, although not evident from the drawing, may have also been placed out of lateral alignment with the lower container.
  • the vertical carrier beams 4 of the side-lift yoke have been placed against the bottom container 7, the two locking bolts 8 being fully retracted inwardly of the side surface 5 during this operation.
  • the truck driver handling the side-lift yoke is able to move the upper locking bolts 8 outwardly of the support surface 5 and into the bottom locking openings 14 of the upper container 7, whereafter the bolts 8 are twisted through 90° so as to lock the upper container to the side-lift yoke.
  • the truck driver is now able to move the upper container 7 both laterally and longitudinally with the aid of the side-lift yoke, so as to bring the upper container into full alignment with the lower container, as shown in Fig. 4.
  • the invention thus enables the upper container to be brought into correct alignment with the lower container and the containers thereafter locked together, with the aid of the side-lift yoke. This has not earlier been possible, and it has previously been necessary either to ensure that the containers are stacked while in precise alignment with one another or to bring the upper container into alignment with the lower container in some way or another.
  • the invention thus provides for simple and speedy handling of mutually stacked empty containers.
