Patent ID: 8585108

Claim:
Container yoke ( 1 ) for simultaneous lifting of two containers ( 2 , 3 ) placed one after the other, comprising a base frame ( 4 ), outer cross beams ( 7 , 8 ) arranged on the base frame ( 4 ) and provided with lock members ( 9 ) for engagement in, and locking to, the outer end portions of the two containers ( 2 , 3 ) facing away from each other as well as at least two essentially centred saddles ( 10 , 11 ) arranged at the base frame ( 4 ) and provided with twinlift boxes ( 14 , 15 ) having additional lock members ( 9 ) for engagement in, and locking of, the two containers ( 2 , 3 ) at the end portions thereof facing each other, the lock members ( 9 ) of one of the saddles ( 10 ) locking one of the containers ( 2 , 3 ) and the lock members ( 9 ) of the other saddle ( 11 ) locking the other container ( 2 , 3 ), and that search levers ( 21 , 22 ) are arranged to aim the locking members ( 9 ) at, and bring them into engagement with, the corner boxes ( 23 , 24 ) of the containers, characterized in that the twinlift boxes ( 14 , 15 ) are coupled and articulately mounted to each other and to the base frame ( 4 ) by means of a system of parallel levers comprising a lower transverse stay ( 20 ) for the movement of the twinlift boxes ( 14 , 15 ) transverse to the longitudinal direction of the base frame ( 4 ), that the lower horizontal transverse stay ( 20 ) is provided with at least one fixed holder-on ( 25 , 33 , 34 ), that at least one actuator ( 27 , 28 , 32 ) in the base frame ( 4 ) is arranged to, during the steering-in phase, avoid mechanical contact with the lower horizontal transverse stay ( 20 ) and let the holder-on ( 25 , 33 , 34 ) and thereby the lower horizontal transverse stay ( 20 ) swing/float freely transverse to the longitudinal direction of the base frame ( 4 ), and that the actuator ( 27 , 28 , 32 ) is arranged to, during the lifting phase, engage mechanically with and press against said holder-on ( 25 , 33 , 34 ) in order to produce a mechanical movement of the lower horizontal transverse stay ( 20 ) and thereby the saddles ( 10 , 11 ) and the containers ( 2 , 3 ) into a desired position in relation to the base frame ( 4 ), for instance in order to attain a centering of the saddles ( 10 , 11 ) and the containers ( 2 , 3 ).
