cantilevered bridge arranged. The weight of the load lift drive mechanism thus generates a counter torque for an operating state in which the bridge boom is in its horizontal operating position is lowered and the loaded trolley next to the sea-side end of the bridge girder stands. In this type of arrangement of the load lifting drive mechanism, an operating state is not sufficiently taken into account, in which the boom is swiveled up, the trolley in the area of the landside bridge section in In extreme cases, even in the area of the land-side cantilevered bridge section - there is wind coming from the sea side loaded the swiveled bridge boom. In this operating state it is used as a tilting edge for stability considerations to take the base of the landside scaffolding disc. Sas around this tilting edge generated the moment of the dead weight of the load lift drive mechanism, which generated around the same tilting edge Moment of the resulting wind power on the swiveled bridge boom, the dead weight of the cantilevered land side Bridge section and, if applicable, the weight and load moment of the land-side cantilevered bridge section around it Tilting edges all work in the same direction and can overturn the crane towards the land.

According to the invention, a remedy is provided here that the Load hoist drive unit attached to the landside scaffolding disc

is arranged.

In a manner known per se, the load ropes can run along the bridge starting from the drive mechanism guided their way along the bridge over pulleys of the trolley and in support rollers of a container mounting frame be reeved and firmly anchored at the waterside end of the bridge; if the bridge is unloaded from the land side the shore-side scaffolding disk can also move the load parts from the engine via pulleys next to the shore-side one Be led at the end of the bridge.

The invention further aims to make it possible for the trolley to still travel onto the landside bridge section even when the bridge section is swiveled up. With regard This aim is further proposed according to the invention that next to the junction axis parallel to the quay wall between the bridge and the scaffolding disc on the quay wall side, load rope guide rollers are arranged, which when the bridge boom is down the track of the trolley are disengaged and take over the guidance of the load hoisting ropes when the bridge boom is swiveled up, in such a way that the trolley can be moved on the landside bridge section.

The disengagement of the rope guide rollers can thereby

bear serene position; these go from across the BrUoke parts of the quay wall-side Gerttstsoheibe. These tensile supports can be articulated on the bridge boom and on the scaffolding plate on the quay wall side and can be designed with knee joints.

A boom adjustment drive mechanism which is used to adjust the boom boom is one of those provided at the beginning Combine tilting moment considerations spatially with the load lift drive mechanism as far as possible; accordingly becomes jib adjustment ropes are run from the jib adjustment drive to plasma trains, which are located between lower blocks on the bridge jib and above the bridge Upper flaps run on the scaffolding disc on the quay wall side.

It is recommended that the broth boom be locked in its folded-up position. To this end you can hang a pendulum-like Yerrlegelungsglled over the bridge on the scaffolding disc on the quay wall side, which in its inoperative position, when viewed parallel to the quay wall, it is in line with the scaffolding panel on the quay wall side.

To make four-sided joints torsion-resistant, one can do the the bridge towering over the Kalmauerelge scaffolding disc Connect to the bridge with stiffening struts, which are located from above and below the bridge run out of the scaffolding disc on the side of the Kalmau and at least approximately in the node axis parallel to the quay wall between the bridge and the landing-side scaffolding disc ends; these stiffening struts can be articulated at both ends be connected to the respective connection parts.

Finally, the invention aims to create a possibility to operate the same container loading crane with different gauges depending on the purpose and place of use to be able to. Accordingly, it is further proposed that the track width of the crane frame should be variable. To the Changing the gauges can be done in such a way that the distance between the scaffolding disks in the longitudinal direction of the bridge makes changeable. For changing the distance between the scaffolding panels there are again two options available: the first option is the landside scaffolding section by changing the length of the stiffening struts attached to different points of the bridge; another The possibility is that the bridge section lying between the scaffolding disks and the stiffening struts can be lengthened are. This latter option deserves at

The trolley 42 Boll at the hoohgesohwenktem Brllokenaueleger 34 remain movable in the subsections 32 and 36 of the Brüoke. For this purpose, as shown in Figures 2 and 4, a pulley 90 is provided, which by means of a Sohwenka: 92 is mounted next to the articulation point 62 of the BrUoken boom 34. When the bridge boom 34 is horizontal, the pulley is 90, as can be seen from Figure 2, swiveled up so that they does not hinder the travel of the trolley 42. In contrast, when the briquette boom 34 is swiveled high, the pulley is swiveled down so that it leads the load lifting cable 51 and that at a height that is unchanged compared to the operating state with a horizontal boom 34. You trolley 42 can therefore continue with the boom 34 pivoted up Drive BrUoken Sections 32 and 36.

The pivot arm 92 has a drive which is not shown. This drive is inevitably coupled with the movement of the bridge boom 34, so that in the horizontal position of the boom 34, the deflection roller 90, as from FIG. 2 is raised, while with the boom folded up, as FIG. 4 shows, the deflection roller 90 their leadership division for rope 51 assumes.

As can be seen from FIGS. 1 and 3, a guide gondola 94 is combined with the trolley 42 let.

Between the frame disks 26 and 26 is, as shown in the Figures 1 and 3 can be seen, a driving level for containers " Means of transport formed; Tracks for rail freight trains, for example, can be laid on this driving level.

As can be seen by comparing Figures 1 and 8, the distance between the scaffolding disks 26 and 28 can be changed and thus the track width of the running rails 16 and 18 Enlarging the track width to the dimension according to Figure 8 are in the Brüokenabsohnitt 32 and in the stiffening struts 86.88 extension pieces 96 or 98 inserted.

In Figure 3 is one of the critical operating states of the Container loading cranes drawn. The folded-up bridge arm 34 is said to be exposed to high wind pressure. This generates a tilting moment around the running rail 16. This tilting moment remains within tolerable limits because the Weights of the drive units 52, 66 are concentrated on the shore-side scaffolding disk 26 and are not themselves in the same Generate effective torque, in contrast to older designs, in which the drive mechanisms inland from the frame plate 36 were arranged.
