ABSTRACT:
An apparatus for loading containers onto and unloading containers from ships, in which the ships receive the containers at locations of varying height, comprises a quayside carrier framework and a travelling carrier system fitted on the carrier framework, with a horizontal track on which at least one container-receiving crane trolley may travel. The travelling carrier system is mounted on the carrier framework for variation in height, with at least one power appliance being provided for the height displacement of the travelling carrier system. The travelling carrier system is supported by a rigid support member which is connected to the carrier framework by a lower link rod system and an upper link rod system. The link rod systems define a parallelogram linkage which is deformable by the power appliance provided, to enable the lifting and lowering of the rigid support member while maintaining the predetermined orientation of the rigid support member in space during its lifting and lowering.
