The invention relates to a transfer plant, especially for loading and unloading ISO containers from container ships at seaports, comprising a vertical support which is propped up on the land side and on which a horizontal extension arm is braced. Said horizontal extension arm, along which a horizontal conveying device can be displaced, protrudes across the ship that is to be unloaded on the sea side. The horizontal conveying device cooperates with hoisting and lowering devices which pick up and put down the containers. The aim of the invention is to create a redesigned transfer plant and a method for loading and unloading containers, preferably ISO containers, from container ships in seaports, which allow the transfer rate to be significantly increased and consequently the lay times of the container ships at the pier to be substantially reduced. Said aim is achieved by disposing at least two horizontal conveying devices () on the horizontal extension arm (), which can be displaced independently of each other along said horizontal extension arm () between the hoisting and lowering devices () that are located on the land side and the sea side. In addition, intermediate storage devices (), into which the containers can be placed and from which said containers can be picked up by the hoisting and lowering devices () that are located on the land side and the sea side and the horizontal conveying devices (), are disposed on the horizontal extension arm in the area of the hoisting and lowering devices () that are located on the land side and the sea side.

Transfer plant and method for loading and unloading containers from container ships

A lifting device for containers comprises at least one hydraulic cylinder arranged on a support frame with a piston and piston rod and at least two, spaced-apart horizontal guiding cross-bars. Lengthwise displacement of the piston rod is transformed into a synchronous upward and downward movement by at least one angle lever pivoted on the support frame. The at least one angle lever comprises two lever arms, one of the lever arms being connected to the piston rod and the other of the lever arms being connected to one of the guiding cross-bars. The guiding cross-bars are connected to a load receiving device for the container and are guided on vertical support pillars of the support frame at both ends for lifting and lowering the container.

Lifting device for containers

An empty container store for the temporary storage of empty ISO containers, in particular in fully automatic container terminals of sea ports or river ports includes a gantry bridge crane which spans the empty container store. The gantry bridge can be moved on an elevated craneway and has a traveling crab which can be moved thereon in the longitudinal direction thereof. A vertical lifting column is fastened to the traveling crab for lifting and lowering a load receiving means for the empty container. The load receiving means includes a spreader on a spreader support which is arranged on a spreader carriage which is guided on the lifting column by rollers on a spreader support.
