According to the invention, there is a crane for a conveyor device characterized in that upper and lower trolley spans are provided in the area of the ends of the crane have vertically opposite gaps «and that at least one trolley elevator is present, which carries a part of the trolley track, which of the elevator can be moved between positions in which it bridges one or the other Bahnlüoke so that the crane can be equipped with several hoists, which of one

Go around the Katzbahn to the other.

In an expedient embodiment of the invention, the mentioned Crane in facilities of the aforementioned type; used with several trolleys that can be moved on the trolley tracks.

One possible embodiment of the invention is explained using an example shown schematically in the drawing. It show ι

A loading bridge consists essentially of a tower 1, which carries a transverse high crane 2, the a sin - as shown - outwards over a ship 3 protrudes, while its other end protrudes inwards

Dock 4 is directed. The crane 2 has a lower trolley track with rails 5 and an upper trolley track with rails 6 and is equipped with three trolleys 7, 8 and 9. The crane 2 has at its two ends in the area of the trolleys 7 and 9 (Fig. L) elevators, which are generally designated 2Λ, 2B and are explained in more detail below.

The elevator 2B in which the trolley 7 hangs is with one provided separated Schlentnabschnitt 5A and in the The positions according to FIG. 1 are directly above the rails 6 there are gaps 6A corresponding to the section. The elevator 2A with the trolley 9 carries rail sections 6B, there is a gap 5B in the rails 5 directly below the elevator 2A.

On each trolley 7, 8, 9 hangs a gripper lo, the operated by a hoist on the trolley and controlled from a crane operator's cabin 11.

Starting from the positions of the trolleys 7, 8 and 9 shown in FIG. 1, the working cycle proceeds as follows. The gripper Io of the trolley 8 lifts a load from> the ship 3. As soon as the gripper Io is at a suitable height, the trolley moves to the right in FIG , which in turn unloads it onto a conveyor 15. At the same time, the elevator 2A lowers in order to introduce the rails 6B into the gap 5B and align them with the rails 5, the trolley 9 moves to the right in FIG Continuation of the unloading process actuated. Also at the same time the elevator 2B rises to the rails 5A

to insert in the gap 6ft and to align to the rails 6, eo that the trolley 7 is calibrated in Flg. 1 after line »can move, the elevators 2Λ and 2B take meanwhile Your starting positions according to FIG. 1 are set again and the trolleys 7 and 8, respectively, travel to the elevators 2A, 2B. Dieter Kreielauf continues the unloading process ended 1st.

The function of each trolley 7, 8, 9 can be controlled either in front of the »crane operator or automatically ·

ATE elevators SA and 2B can also be monitored by the crane operators or operated automatically if the trolleys are or are in the elevators leaving. The lifting tool should be appropriate from the Crane operator are operated.

In the embodiment shown, the crane 2 and 2 protrude the upper end of the lower cat tracks to form Abetell possibilities for the trolleys in over the On train 2B out. The outwardly protruding end of the crane 2 is in a known manner about an axis 12 upwards can be swiveled so that it is sufficiently far from the superstructure of the ship is removed when it is berthed takes or leaves it.

The elevators 2A and 2B are formed in a similar manner and therefore only the elevator 2A will be described in detail. This elevator essentially consists of a frame 16, which carries the rails 6B and is guided between pillars 17 during the upward and downward movement, with upper and lower bearing pairs 18, 19 (Pig. 4) the in the PIg. 2 bjBWr 5 d & rgestell ^ th upper and lower positions, the lifting and lowering mechanism, which is generally designated 2o in Fig. 1, has (Fig * 2
