• Ship double jib crane

Double jib cranes are known which are used in mobile loading systems. Besides one is immediate slewing crane arranged on a movable underframe another slewing crane at a greater height on its own, arranged on the chassis, supported substructure. The upper crane or its substructure rests on a column whose axis goes through the fulcrum of the lower crane, which is built around it so that it can rotate independently of it and which it only serves as a Leadership serves "

This is intended to ensure that the cranes do not interfere with one another in their rotating range. The known cranes can work independently of each other. However, using both cranes to lift a load together creates difficulties with regard to the lifting and swiveling movement. There is also the part that the center of gravity of the system is very high due to the elevated position of one crane (DoP.542 45o) ₀

It is also known a loading device, especially for sea and inland ports, which consists of a loading bridge consists, on which a turntable is arranged, which in turn carries one or more slewing cranes. Here you can

the cranes arranged on the rotating axle also uv; ei in opposite directions Directionally working double link or simple luffing slewing cranes.

These well-known double slewing cranes have the roof part that each crane needs its own crane thawing system and its own counterweight (DBP 8o1 7o6) _{or similar}

The innovation avoids the disadvantages of the known double slewing cranes. The invention has set itself the task of building a double heavy-duty crane so that the Crane superstructures and the counterweights are omitted as far as possible »Nonetheless, the individual cranes should be independent of one another work or together for ^ e- or unloading be used by larger loads.

The innovation concerns a ship's double jib crane with two pivotable crane jibs that are arranged around a common vertical axis and pivotable about horizontal axes at their ends. The invention consists in the fact that the crane jibs can be pivoted at their pus ends around a vertical axis on one Turntable are mounted, which od with a mast with a cross member, trestle is.

The innovation solves the problem according to another embodiment in that the crane jibs at their pus ends each a vertical axis are pivotably mounted on a turntable, which is penetrated by a mast firmly connected to the ship is, which carries a cross member for attaching the hoist ropes, the cross member to the same extent as the turntable is pivoted.

The innovation results in the advantage that a simple arrangement of a double slewing crane is created, with each

In the embodiment according to Fig. 1, the substructure 1 is one Double slewing cranes on deck 2 of one not in detail The ship shown is arranged between the two hatches 3 and 4. A rotary disk 6 is mounted on the substructure 1 via a spherical rotary joint 5. The rotary ball joint 5 is of this type designed so that it transmits the tilting moments exerted on the turntable 6 to the substructure 1. Both sides of the vertical Pivot axis 7 of the turntable 6, the crane booms 8 and 9 are mounted, the vertical pivot axes 1o and 11 at Embodiment 1 are at the same distance from the pivot axis 7 »Two small ones are used to support the crane booms 8 and 9 Turntables 12 and 13, which are also connected to the turntable 6, for example, via rotary ball joints 14, 15 can, so that the forces and moments exerted on the turntables 12 and 13 can be transferred to the three-disc 6 "

The turntables 12 and 13 carry displacement brackets 16 for the horizontal pivot axes of the crane booms. The turntables 12 and 13 and the turntable 6 are via drives not shown in detail, such as turntable pinions or hydraulic Part-turn actuators, driven. The drives can be shifted in the turntable 6 and are independent of one another.

Fixedly connected to the turntable 6 is a mast 17 »which is accordingly is also rotated by the turntable 6 when pivoting The mast 17 carries a cross member 18 ^ at its upper end which can be pivoted vertically on both sides coaxially with the axes 1o and 11 Has consoles for holding rollers 19, via which the lifting and luffing cables 8a, 9a for the crane booms 8 and 9, respectively can be guided.

Instead of the rope luffing mechanism, other types of luffing mechanism can also be used.,

Fig. 3 shows the possibility of how the two crane booms 8 and 9 can pivot and work independently of one another ^{from the position shown in solid lines into position 8 'and 9 1 shown in dashed lines.} The turntable 6 can be brought into a position that is most favorable for the work of the individual cranes 8 and 9.

Fig. 4 shows the double crane with the crane jibs 8 and 9 in the working position, in which the double crane with the double Payload, based on the load capacity of the single crane, is working. Here the individual slewing mechanisms are the crane booms 8 and 9 shut down. The pivoting takes place via the rotating mechanism, not shown, which is arranged below the turntable 6. the Lifting and luffing mechanisms of the two single cranes 8 and 9 are in this Case operated synchronously by a crane operator.

The embodiment shown in Fig. 5 differs from that shown in Fig. 1 in that instead of the Rope luffing mechanism a hydraulic luffing mechanism is used. The mast 17 carries a cantilever arm 21 on both sides, in one Universal joint 22 or, in a similar embodiment, a hydraulic one Working cylinder 23 carries. The cardanic suspension 22 is arranged coaxially to the axis 11.

The cranes shown in Fig. 6 differ from those previously described in that the pivot axis 1o of the crane boom 8 is coaxial with the pivot axis 7 of the turntable. In contrast, the pivot axis 11 of the crane boom 9 is arranged laterally. The lower end 24 of the crane boom 8 is fork-shaped and surrounds the mast 17. Around the foot end of the mast 17, which is firmly connected to the turntable 6, a circular ring disc / is pivotably mounted on both sides the horizontal bearings for the fork-shaped foot end 24 of the crane boom 8 carries. The circular ring disk 25 is also provided with a drive not shown «

The pivot drive of the crane 8 can now be coupled to the pivot drive of the turntable 6 in such a way that when the turntable 6 is pivoted, the crane boom 8 is pivoted in the opposite direction by the same amount, so that it practically stops. This has the advantage that the crane boom 8 is completely independent of the rotary movement of the turntable 6 during operation _e

The ropes of the crane boom 8 are at point 26 on the mast 17 over posted a swivel castor chair 27. The ropes of the crane boom 9 are also via a swiveling roller chair 27 posted, which is shifted on a one-sided traverse 18 firmly connected to the mast 17 »

Fig. 7 shows an embodiment in which the Hast 17 is firmly connected to the substructure 1. The turntable 6 is perforated and the transverse traverse 18 is displaced vertically pivotably on the box 17. The transverse traverse 18 is driven synchronously with the turntable 6 via a swivel drive not shown

The embodiment of Figs. 8 and 9 differs from that according to Fig. 1 initially in that the mast 17 is designed as a cabbage mast and is penetrated by a mast 28, which also the turntable 6 is penetrated in a corresponding opening and is firmly connected to the substructure 1. The hollow mast 17 in turn carries a cross member 18 on both sides for attaching the ropes for those displaced on the turntable 6 Crane boom 8 and 9o The one firmly connected to the substructure 1 Mast 28 can now be used to attach the ropes of a loading boom 29, for example for lifting particularly heavy loads can be used «» This loading boom 29 is shifted on the turntable 6 over a horizontal axis 3o so that it can be tilted. The hanging and hoisting ropes 31, 32 are guided over the rollers 33. The pulleys 33 are pivotable about a vertical axis Head piece 34 relocated. The lifting and luffing ropes of the loading boom 29 can be wound onto the winches of the double slewing crane.
