DE19623164C2 - Inland watercraft - Google Patents

Description

The invention relates to a watercraft for inland waters according to the preamble of the main claim.

The handling of general cargo in and out of an inland ship or a barge is usually used by means of a port crane system in the vertical direction carried out. The turnover speed is here essentially by striking the Transportbe container and the traversing speed determined. On large inland waters such as the Rhine and angren waters has an extensive container traffic is established and there is one in the ports appropriate infrastructure in the form of container bridges.

Recently, the so-called RoRo technology has changed introduced for special applications that game for car transports, truck trailer transport and  Heavy goods transport is applied. Drive in the process the motor vehicles with their load on access ramps directly into the hold, stay there during transport on the inland water and fah upon arrival at the destination out. A fundamental problem of roll on roll off technology (RoRo) are the access ramps there they can only have a limited inclination. Each the smaller the watercraft, the more take the access ramps away from the hold.

A generic watercraft is from the Engli magazine "Ship & Boat International", issue 2, March 1984, pp. 15 and 16. That water Vehicle has a front flap that is used for unloading of vehicles on the loading area through two cylinders is folded down. With the help of the cylinder and the bow flap the bow of the watercraft is raised, to create a permanent connection to the jetty fen.

The watercraft of this type has several disadvantages on. The lifting of the ship is done by the rotatori cal movement of the flap accomplished, so that the Swivel axis of the loading ramp and its storage very ho hen must withstand forces, this requires high constructive effort. Since when lifting by means of Flap very unfavorable leverage conditions exist, this can shorten the length of heavy ships Flap or an extremely complex version is required other. Another disadvantage is an excessive opening trees of the bow using the flap. This means one for loading and unloading the vehicles "Ascent and descent" for those in the picture shown off-road vehicle is not an obstacle provides, but is unsuitable for container freight.

The invention has for its object a gat tional watercraft so that with heavy loads can be loaded and unloaded nen.

This task is done with a generic water vehicle by the characteristic features of the Main claim solved.

The fact that a separate lifting device for lifting the hull in the area of the loading ramp is provided, the loading area of the water ride Stuff about the water line approximately according to the height the jetty can be raised so that the piece well-transporting motor vehicles over the drawer can drive directly into the loading space. Thereby becomes no room for one in terms of their inclination limited access ramp consumed. In contrast to Container bridges are relatively minor construction measures the port facilities necessary and it can also be the same more watercraft are loaded and unloaded at an early stage, making the cost of the handling process significant be lowered. The necessary measures can be taken any number of berths can be provided.

With the extendable on a fortified embankment The watercraft on the Drive along the embankment somewhat towards the shore. If necessary, ver can be used on fixed pier facilities to be waived.

By the measure specified in the subclaim is an advantageous training and improvement possible.

The invention is set out in the description below explained in more detail.

In the hull of a watercraft for Bin A loading space is provided in open waters spans essentially the entire ship and in trucks with containers, for example be included. The loading area of the cargo hold is below the waterline. The watercraft is provided on its bow with a flap that the La the room closes to the front. The flap is folded down bar, forming a loading ramp.

For the loading or unloading process, the Watercraft can be raised at its bow so the flap forming the loading ramp can be folded down can roughly match the height of the pier Right.

For this, the watercraft is equipped with an over hydrau extendable chain undercarriage provided that for loading and unloading to raise the bow of the Ship can be extended and on one supports the firm ground of a fortified embankment. There at the rear of a tractor or the like. Fixed being held. With the chain undercarriage it is possible Lich, with the bow raised towards the Move the bank until the flap that opens is above the Waterline lies. Over the loading ramp and the befe Whoever is on the bank can now load and unload the ship the. The crawler track must be calculated so that the ship back into the open water after loading can be brought.

In the example shown, the flap is at the bow of the Watercraft provided, of course, can  the flap should be arranged at the stern.

Claims (2)
