Abstract
Abstract A crane for loading and unloading a containership and for transferring the containers between the ship and land vehicles is equipped with normally stationary hoists on the portions of its beam which are above water and above land respectively. The containers lifted by one hoist and lowered by the other are transferred between the hoists on the platform of a carriage traveling horizontally on the crane beam and automatically controlled by limit switches. Two carriages and two hoists on the land side of the crane can normally be served adequately by one hoist on the sea side of the crane without interference if the two carriages travel on different levels, and the hoist on the land side cooperating with the higher carriage is farther removed from the hoist on the sea side than the other hoist on the land side.
