Abstract
A container yoke for lifting of at least one container, including a base frame, two travelling beams, which are telescopically displaceable in the base frame and on whose outer end portions are arranged transverse beams provided with locking members, so called twist locks, for engagement in, and locking to, the corner boxes of a container. The container yoke includes cables arranged to displace a respective travelling beam into the desired position in the frame of the container yoke. The cables, for displacement of a travelling beam, are simultaneously reeled up and unreeled with the aid of one and the same cable drum. Two cable drums of the container yoke are driven by a common actuator, and the cables are fastened in the end portion of a respective travelling beam via spring-loaded cable tensioners.
Claims5
