METHOD AND CRANE CONNECTION FOR CARRYING LOADS AND UNLOADING

The invention relates to a method for performing controlled loading and unloading from a cargo space, in particular a ship's cargo space, wherein the cargo is moved by means of a mobile boom crane comprising a pivoting means for rotating the boom about a vertical bar and one frame is positioned above the cargo space and the pivoting device and the downwardly facing crane pivot frame 15 are moved on said frame in a horizontal direction.

The invention further relates to a lifting arrangement implementing the method.

20 It is known in the art as port cranes to lift cranes on the rails next to the ship with a pivoting device on the hull so that the crane booms can be • •: 1 ·· in different directions. At the end of the boom are the fastening ropes ·· «· ... · and the lifting hook depends on the ropes. Cargo 25 is difficult to handle due to a suspended lifting hook and: .2 stopping cargo movement for precise positioning ··· * ··· 1 takes time.

• · • m: "Bridge cranes with long horizontal • · * · 2 · 1 30 beam, which are positioned high enough in support structures • · V.2 in the transverse direction ··· · ..., are still known ... · In the horizontal The beam is fitted in the direction of the beam: 3: the movable trolley on which the lifting hook depends on the lifting straps • The disadvantage of this type of crane is that 2 3 2 118595 loads are slow because both the trolley and the horizontal beam Also, stabilizing the load rocking for precise si-5 alignment is difficult and time-consuming.

EP 359975 A1 discloses a crane assembly in which the horizontal frame of the crane is located above the cargo space. Below the frame is attached a pivoting device, from which a boom extends, at the end of which the lifting device is pivotably movable above the cargo space and the unloading field. The hoist includes a rope hoist, which enables vertical movements of the load.

DE 19518618 A1 discloses a crane assembly in which a horizontal beam located above the cargo space is provided with a boom swivel frame and a boom extending downward from it. Loads may be moved between unloading and cargo spaces on the ground, but loading over the ship's side 20 is not possible by maintaining the crane in a constant position in the horizontal beam.

With the method of the invention, controlled loading and • · * · *. to perform the discharge, the above-described calculations are solved • ♦ ... The problems with the 25-tile transfer and the method of the invention are characterized in that the pivoting body is moved * · «· in said body substantially above the edge of the cargo space and the pivoting body is used to rotate the boom, ···. that the end of the boom is movable between the cargo • space and the unloading / loading field.

• · · • · ·.

The crane assembly according to the invention is characterized by ·· *: *. · That the pivot frame can be moved substantially over the cargo area edge and the pivot frame 3 5 118595 allows the boom to be rotated, that the end of the boom is movable between the cargo space and the unloading / loading field.

Advantages of the method according to the invention are that the crane allows the cargo to be moved without a significant sway of the load along a defined lifting path. Thus, the transfer of cargo takes place quickly without the delays caused by the removal of the sway 10. Cargo lifting and handling is also accomplished with very little crane movement when the boom swinging device is positioned over the edge of the ship's cargo space where it can be stationary during the transfer of many loads. This results in 15 efficient loading operations, reducing the risk of cargo damage, and improving safety and productivity at work. The operation of the crane and its frame design allows the crane to be covered immediately above the horizontal beam. The roof structure may be partially or completely connected to the crane frame-20 structure. In this case, all loads can be loaded even in the rain.

In the following, the invention will be explained in more detail with reference to the accompanying drawing, in which: * * * Figure 1 shows the crane and the cargo space of the ship as seen from the ship's mouth.

Fig. 2 is a top view of the crane.

Figure 3 shows the crane moving along the edges of the cargo hold; ** Installed as an image.

··· • · **: * '3o • · v: Figure 1 is a port crane according to the invention, with columns 1 and 2 positioned such that column 1 is in the same direction. and the opposite carrier pillar 2 is located at a distance greater than the breadth of the ship on one side, established at the bottom of the sink 4 118595. Thus, the loaded vessels can be guided between the pillars There are several pillars 1 and 2 on each side and are rails placed near the top of the pillars so that the horizontal beam 4 as a whole can be supported on rails in the direction of the ship.

Alternatively, the rails are located both in the harbor area 10 14 and on the other side of the ship, and the horizontal beam 4 with its vertical support columns 1, 2 is driven as a unit in the ship's direction at various points in the ship's cargo space. Both of the above solutions apply to the displacement of the horizontal beam 4. But if, according to the invention, it is desired to cover the loading site so that the roof structure 15 (Fig. 1) at least partially utilizes the vertical columns 1 and 2, a better coverage result is obtained by the solution that the vertical columns 1 and 2 are solidly formed.

A third possibility of moving the crane is shown in Fig. 3, in which the crane is movable by means of wheels 17 on the edges 3 of the ship's cargo space 13. Horizontal beam 4 rests on vertical ··· frames 16.

25 ·· ♦: V According to the invention, the boom 7, 8 of the crane is fastened to the horizontal beam 4 so that the pivoting body 6, which is able to pivot about the vertical axis, protrudes downwards from the horizontal beam 4. At the lower end of the pivot body 5 • · '·; ** 30 is attached a first boom 7 which is movable • · V,! slit by means of the cylinder 9 and the extension of the boom 7 is still a second boom 8 which is moved by the cylinder 10. la. Also, the telescopic extension boom may come in question • i: * ·. · To replace the other boom 7 or 8 or be fitted with an extension * · 5 118595. The pivoting device 6 is mounted on the horizontal beam 4 via a separate movable carriage, whereby the pivoting device 6 and at the same time the pivoting center of the pivoting body 5 can be moved to the desired position in the horizontal beam 4.

When, in the loading situation, the turning body 5 is driven along the horizontal beam 4 above the edge of the ship's cargo space 13, a very advantageous loading movement is obtained either from field 14 to cargo-10 or vice versa. The pivot frame 5 can be held in place in the horizontal beam and is pivoted only to orient the boom between the lifting and lowering positions. By guiding the booms 7 and 8, the cargo 11 can be moved directly to or away from the cargo space by means of a gripper 12 or the like 15 attached to the end of the boom 8.

Figure 2 is a top plan view of a crane assembly. The boom 7, 8 must be turned, for example, at an angle a when loading Figure 2. In preferred loading, the angle α is 60 to 20 1 80 °.

Naturally, the pivoting device 6 has a pivoting body 5 rotatable about its vertical axis at all angles. With a crane assembly similar to Figures 1 and 2, 9 · 25 can be controlled by a remote control, eg ship 9 9! ···. from one side sufficient for one person to steer, as he / she 9 · can see well both the cargo compartment 13 and the field 14. · 11 transmission speeds can be many times higher than the • 99 9. ***, which is transported on a wire hanging 999 Λ 30 hook.
