Definitions
- the present invention refers generally to lifting devices for standardized goods containers, and more closely to a lifting yoke or a lifting frame for handling such containers .
- the present invention refers, for example, to the type of lifting yokes described in Swedish published specification 7407425-3 and comprising a central frame unit which is supported, for example, by a crane or other lifting device, generally by the aid of cables. Extending from the central frame unit are two pairs of substantilly parallel beams , one pair in either direction. The outer ends of the . corresponding beam pairs are mutually connected ty cross-bars.
- the beams extending from the central frame unit are adapted to be extended and retracted in relation thereto for adjusting the mutual spacing between the cross-bars to enable the lifting yoke to be adapted to various container sizes.
- the cross-bars are provided with downwardly extending rotary blocks adapted to be inserted into the upper corner boxes of the containers and locked therein to enable the containers to be lifted.
- At the outer edges of the cross bars there are normally upwardly and downwardly swingable feeler arms guiding the lifting yoke into correct position during lowering towards the containers and thus, causing the rotary blocks correctly to meet the openings of the corner boxes in question.
- the containers are deformed and that the rotary blocks encounter difficulties to meet the holes of all the four corner boxes.
- the adjustment of the lifting yoke is so exact that already displacements amounting to some few milimetres between the four corner boxes may cause the lifting blocks to meet only two or thr-ee of the openings of the corner boxes. In such cases the lifting yoke is blocked so that a lifting cannot be performed. Accordingly, it is desirable that the yoke is slightly flexible in order to be able to compensate for deviations in the spacing between the corner boxes of a container.
- the object of the present invention is to remove the above problems and this object has been reached by a device of the type referred to in the claims from which also what- is especially characterizing the invention is clear.
- Fig. 1 is a schematic upper plane view of a lifting yoke constructed according to the invention
- Fig. 2 is a schematic view, partially in section, through the lifting yoke shown in Fig. 1 showing a preferred embodiment of the invention
- Fig. 3 is a broken, partially sectioned view showing a detail of the invention.
- the lifting yoke 1 shown in Fig. 1 comprises a central frame unit 2 having pairs of side beams 3 , 4 adapted to be extended and retracted in relation to the frame unit 2. At the outer ends said cairs of side beams 3 , 4 are connected by cross-bars 5 , 6 which at their outer ends support devices 7 including lifting blocks and feeler arms.
- the outward and inward shifting of the pairs of side beams 3, 4 is performed with the aid of specific operating arms 8, 9- These are guided in the central frame unit 2 and attached substantially centrally of the cross-bars 5 , 6.
- the operation is performed by the aid of a motor 18 driving one 9 of the operating arms and this movement being transferred to the other operating arm 8 by su i means as chains.
- Feeler means (not shown) mark the various adjusting positions of the lifting yoke which thereby is ad justed to a length corresponding to the length of the container in question.
- FIG. 2 there is schematically shown an arrangement of the resilient mounting. From the cross-bars 5 and 6 there extend operating arms 8, 9 towards and above each other in the same way as in connection with the lifting yoke in acorrdance with Fig. 1.
- a resilient mounting 20 between a looped chain 21 and each operating arm 8, 9 is at the ends of the operating arms.
- the chain 21 runs around two opposite sprocket wheels 22 , 23 one at each end of the central frame unit. One of said sprocket wheels 22 , 23 is driven for the movement of the chain 21 and accordingly for the adjustment of the yoke.
- the resilient mounting 20 is clear from Fig. 3.
- a cross-piece 24 secured by welding.
- Said cross-piece 24 extends from the qperating arm in the direction towards the chain 21 and is in the extending portion provided with a thorough opening 25.
- a rod 26 extends through said opening 25 and each end thereof is connected to the ch-ain 21.
- the rod 26 is threaded and two pairs of nuts 27, 28 are screwed onto the rod one pair on each side of the cross-piece 24.
- Figs. 2 and 3 may be used separately in the lifting yoke or in combination with any known structure.
- the embodiment in accordance with Figs. 2 and 3 is also of the advantage that it is easy to mount in connection with repair or altering of a prior yoke.
- the lifting block still can penetrate into the openings of the corner boxes under the action of the weight of the yoke.
- the inserting ends of the lifting blocks are slightly conical the insertion into the corner boxes in contact with the walls of the openings will produce a tendency towards a shifting of the cross-bars 5, 6 outwardly or inwardly in the longitudinal direction of the yoke.
- spring action in the attachments 20 such a limited moment in the plane of the yoke enables also deformed containers to be lifted without specific rreasures.

Abstract
Joug de levage pour conteneurs et analogues. De tels jougs de levage comprennent une unite de cadre central pouvant etre suspendue dans un dispositif de levage dont l'unite de cadre soutient les traverses (5, 6) pouvant se deplacer vers ladite unite et a partir de celle-ci, les deplacements de ces traverses etant provoques par l'action d'un dispositif par l'intermediaire d'une transmission. Les traverses (5, 6) soutiennent a leurs extremites exterieures des dispositifs comprenant des blocs de levage. Entre l'unite de cadre et chaque traverse (5, 6) sont disposes des bras d'actionnement (8, 9) etendus. Au moins un moyen elastique (20) est compris dans la transmission entre le dispositif (18) et une traverse, le moyen elastique (20) permettant un mouvement limite de la traverse (5, 6) dans le plan du joug par rapport a la position determinee a l'aide du dispositif et de la transmission.
