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.

Claims (21)

1. A container yoke for lifting of at least one container, comprising:

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 for engagement in, and locking to, the corner boxes of a container,

characterized

in that cables are arranged to displace a respective travelling beam into the desired position in the frame of the container yoke,

in that the cables, for displacement of a travelling beam, are arranged to be simultaneously reeled up and unreeled with the aid of one and the same cable drum,

in that both cable drums of the container yoke are arranged to be driven by a common actuator,

in that the cables are fastened to the end portion of a respective travelling beam via spring-loaded cable tensioners, and

in that at least a part of the cables runs between the travelling beam and the frame and that at least another part of the cables is disposed above the frame.

2. The container yoke as claimed in claim 1 ,

characterized

in that the actuator is an electric motor.

3. The container yoke as claimed in claim 1 ,

characterized

in that the cable drums arranged to rotate synchronously via a common axle.

4. The container yoke as claimed in claim 1 ,

characterized

in that the cable tensioner is arranged to eliminate any slack in the connected cable with the aid of a preloaded spring.

5. The container yoke as claimed in claim 1 ,

characterized

in that the cables for each travelling beam are arranged to be reeled or unreeled via a single cable drum.
