DE3837726A1 - Process for the loading of heavy cargo by means of a heavy-cargo loading bridge having more than one raising and lowering device - Google Patents

Abstract

The process, for which a patent is applied, for the loading of heavy cargo by means of a heavy-cargo loading bridge is characterised in that, in a loading bridge, by means of two or more raising devices working independently of one another, the raising and lowering cycles during the transfer of cargo to be raised, especially of containers during loading and unloading, can be shortened and the horizontal transport of the load can be carried out separately from the raising and lowering operations. The apparatus for carrying out the process allows a further shortening of the work cycles during the loading and unloading of heavy loads, in that one or more transport vehicles for the horizontal load movement can convey the heavy load independently of the raising and lowering devices. A further shortening of the work cycles becomes possible in that the further raising devices or transport vehicles, impeding the travel route of a raising device or of a transport vehicle, can be moved away and, after the vehicle having priority has passed, can be returned to the travel route.

Description

The present invention relates to a method for Loading heavy goods with a heavy goods loading bridge. Such loading bridges are also used for loading and unloading container used in ports. Because of the below different dimensions of the ships to be loaded or unloaded the loading bridges have high supports. Resulting from this themselves when loading and unloading containers from ships also large lifting heights.

The lifting heights are also influenced by the fact that one Transhipment of heavy goods from ships at low and high tide can make it noticeable.

The heavy goods loading bridges work with a lifting and Lowering device, all of which are required for handling Performs operations one after the other. These are:

• 1. Coupling a container from the feeder vehicle
• 2. Lift the container to the transport height
• 3. Move the entire lifting and lowering device with hanged container over the ship to be loaded
• 4. Lower the container and align it with the stack space
• 5. Put on the container
• 6. Unlock the container
• 7. Lift the empty carrying device called the spreader Lifting and lowering device to the transport height
• 8. Empty travel of the entire lifting and lowering device with the Spreader over a feeder vehicle
• 9. Lower the spreader and align using one to move container
• 10. Coupling the container e.g. on the feeder vehicle

The procedure is the same when unloading ships applied.  

The drivers of lifting and lowering devices on heavy goods Loading bridges are trying to change the handling times for one Heavy load, e.g. to lower a container by: Horizontal travel already during lifting and lowering from the point of lifting to the drop point, or vice versa, initiate. As a result, however, the load in particular can Wind swaying, leaving the exact handover point or receiving point for a container by swinging out with the associated loss of time must be targeted.

Another disadvantage of this handling method with today's heavy-duty loading bridges are that the entire lifting and lowering device with the suspended load must be transported horizontally. Thereby you take lower driving speeds, higher energy consumption luste for accelerating and decelerating the loaded He loading and lowering device and thus greater wear in purchase. In addition, the driver's workload is the Lifting and lowering device with this working method in the Ver same very large.

The disadvantages described can be with the now presented Method for loading heavy goods with a heavy goods Loading bridge with two or more independently of each other working lifting and lowering devices in a loading area bridge must be fixed because the horizontal transport of the The load from the pick-up point to the transfer point is then separated from the Lifting and lowering can take place.

This procedure allows a large decoupling of the operations to be carried out when handling containers Lifting, transporting and lowering when you go to the horizontal transport independent transport with tel operated.

The described invention is therefore based on the task de, the disadvantages of a known loading bridge for heavy goods, in particular containers, as well as the Handling performance and reliability of a loading bridge  to increase significantly. According to the invention, the task solved in that the necessary for an envelope Work steps largely decoupled and therefore also through the use of electronic data processing better become partially automated.

The decoupling of the required for the handling of heavy goods Such steps are solved according to the invention that more than one on a heavy lift dock Lifting and lowering device can be used simultaneously can. The advantage of such a solution is that par a lowering cycle can be carried out all the time during the lifting cycle can, which initially results in comparable working heights and speeds double the delivery rate when lifting and lowering. Because the job of each The lifting and lowering device no longer also the horizontal transportation is with a shortening of the time for that Align when lifting and when loading count because the lifting and lowering devices are aligned stay. Because there is no swinging of the load by hori zonal acceleration and deceleration of the entire He loading and lowering device can also be done by this expect an improvement in turnaround times.

Another advantage of using more than one Lifting and lowering device in a heavy goods loading bridge can be expected that the wear in the system components can be reduced because of the dynamic force te significantly reduced.

As a rule, when handling heavy loads in the ha the working heights of the load-receiving side and load deposit page of different sizes. The described invention was hence the underlying task, the different Times of the work cycles on the load side and on the load drop side by an independently executable Compensate for horizontal transport of the load. According to the invention the object was achieved in that one or more  Transport vehicles for horizontal load movement independently of the lifting and lowering devices the heavy load between can transport the pick-up point and the drop point. Since these transport vehicles also without spreader and device device for lifting and lowering loads they are comparatively light. This is also the reason Total weight when loaded is much smaller than during transport of a container with a manned lifting and lowering device tung. As a result, the energy consumption for the horizontal transport as a further advantage also shorter Travel times attainable. Accordingly, the wear on the track and structure become comparatively smaller. As Another advantage is when using independent Transport vehicles according to the solution according to the invention available that the horizontal transport unmanned and full can be automated.

Another solution according to the invention provides the vehicle to train ge for heavy-duty horizontal transport that the heavy load taken over stands up and does not hang. In Such a solution ensures that the load is not through the influence of acceleration and wind in the pen deln what can be another advantage for the Ar safety and to shorten the horizontal travel times can be cited.

An embodiment of the invention is in the drawings and shown in an attached model photograph and is described in more detail below.

Show it:

Fig. 3 is a model photograph of the arrangement according to FIG. 1 with two functioning lifting and lowering devices and an independently moving transport vehicle.

A solution according to the invention for the method for loading heavy goods with a heavy goods loading bridge, in particular containers, is due to the structure of the loading bridge supporting structure 1 on rail carriages 2 , which can be moved by the wheels 3 on a rail track 4, the entire loading bridge Ver , reached. The Tragkon construction of the heavy goods loading bridge supports a loading boom 5 , which can be angled upwards in the main boom area 6 in order to allow ships of different heights to pass through for ship loading and unloading. In the one presented solution according to the invention, the loading boom has two rail travel routes 7 and 8 . On the rail track 7 there are two lifting and lowering devices 9 and 10 for heavy loads in the solution presented. The lifting and lowering device 9 works in the presented solution on the land side, while the device 10 is arranged on the water side.

The construction of a lifting and lowering device corresponds the already known constructions. This is first ensures that existing design documents, construction parts and spare parts can be used. An advantage when building a heavy goods loading bridge with inclusion Known lifting and lowering devices, it is also that these can also be used conventionally if this is for Example for repair work on a device or on Transport vehicle would be required. However, it is after the Another solution according to the invention conceivable, cheaper Constructions for lifting and lowering devices on the ground to develop less stress in the company.

The lifting and lowering devices 9 and 10 carry the drives and mechanical equipment for lifting and lowering containers. The so-called spreaders 11 and 12 are used to couple the containers to the lifting and lowering devices. The spreaders can be used in the known construction forms and can also be adapted to different container sizes.

The rail track 8 is provided in the solution according to the Invention for one or more horizontal transport vehicles 13 . A horizontal vehicle takes a container from a lifting and lowering device and conveys it via the loading arm 5 to a further lifting and lowering device, which takes over the container supplied in this way and lowers it to the unloading point, for example in a ship 14 . Already during the horizontal transport of the container, the onshore lifting and lowering device 9 can lower its spreader again in order to pick up another container from the load pick-up point, for example a rail vehicle 15 guided under the lifting and lowering device 9 , loaded with a container charge.
