Transport for the purpose of transport

The present invention relates to a vessel for transporting timber and the like, which is able to eliminate the major disadvantages which arise when timber is to be towed as long ferries to a destination. Towing of ferries can usually only take place in calm weather, because the bundles in the ferries can be released from the ferry by the effect of a very small wave, which naturally has both practical and economic disadvantages. In addition, the towing of ferries is very slow, which can lead to production delays at the destination.

The invention is essentially characterized in that the devices for holding the retracted bundles of timber in place are intermediate decks arranged between the sides of the ship and longitudinal parallel bulkheads which divide the ship transversely into a number of spaced cargo spaces. The invention thus provides a timber and similar transport vessel which is easy to load and unload. Because it is virtually independent of weather conditions and is made to travel at a relatively high speed 2 63707, it is clear that it is able to eliminate the disadvantages commonly encountered in towing timber rafts.

The invention is described in more detail in the accompanying drawing, in which an embodiment of an transport vessel according to the invention is described by way of example.

Figure 1 shows the vessel from the side and Figure 2 again from above.

Figure 3 shows the vessel on a larger scale as seen from the rear in different loading positions, and Figure 4 illustrates some perspective details of the vessel in a perspective view.

The vessel 1, which in the construction shown in the figure is substantially shaped as a shipyard, is open at one end, so that bundles of wood goods 2 and the like can be pulled inside it. The other end of the vessel could also be open, so that the bundles of timber 2 therein can be pulled in the same direction as when the vessel 1 is unloaded. However, more generally, ship 1 has only one open end, so the bundles of timber are pulled from it in the opposite direction to the loading direction when the cargo is unloaded.

As usual, the ship 1 can be partially submerged below the surface of the water, whereby bundles of timber 2 floating in the water and the like can be pulled into it to different height levels. Furthermore, since the vessel 1 is equipped with devices 3 with which the bundles of timber 2 can be attached to it in different levels, it is clear that the vessel has a large transport volume. In addition, it is easy to load and unload.

The timber bundles 2 are attached to the vessel 1 on different levels in the intermediate deck 3. They are arranged to prevent the timber bundles 2 from rising to the "surface", i.e. to move out of place when the vessel 2 is submerged as loading continues after one level to the next loading depth.

As can be seen from Figure 4, the intermediate covers 3 consist of movable units which can be locked at least in the positions in which they act as intermediate covers. More specifically, the intermediate covers 3 are pivotally mounted on the vessel 1, so that they can be locked in both the upper and lower positions. The devices required for locking in the lower positions are marked with the number 4, while the locking devices required for the upper positions are marked with the number 5.

According to the preferred embodiment shown in the figures, the vessel 1 is provided with two longitudinal partitions, i.e. bulkheads 6 and 7, between which intermediate decks 3 are arranged. The number of partitions may, of course, vary.

3 63707

At the end opposite to the open end of the vessel, winches or similar devices 8 are arranged for pulling floating bundles of timber 2 or the like onto the vessel. The end of a ship with winches is usually its bow. Winches or similar lifting devices 8 are provided for guiding the intermediate decks 3 pivoted onto the vessel, which preferably use the same winches as for retracting the timber bundles 2. Openable pulleys 9 are used to guide the intermediate decks 3, i.e. the so-called heittotaljoja.

Winches or similar lifting devices 8 are also provided for lifting the towing boat belonging to the vessel 1 to the vessel 1 and lowering it back into the water. The task of the boat is e.g. tow bundles of wood for loading and unloading 2 pallets.

Like the car deck, the ship 1 is equipped with closing hatches at its open or both open ends, so that it cannot be hit by a wave during transport.

As can be seen from Figure 3, the bottom deck of the vessel is lowered so deeply underwater during loading that the parallel bundles 2 can be retracted by the winches 8 arranged on the bow of the vessel 1 floating in the water. When the entire lower, water-filled lid is loaded with bundles 2, the first pivotable intermediate lid 3 is lowered and locked in this lower position.

Po. the deck prevents the bundles 2 from rising when the vessel is re-immersed to load the intermediate deck with the bundles 2 being pulled over it. When all the intermediate decks 3 are fully loaded with the bundles 2 en. using the method, the base 1 is raised so much that its lowest lid remains above the water surface. When the vessel is "immersed" in water, it is filled with water as shown in Figure 3, and when it is lifted upwards, the water flows out of it. Once the vessel has been emptied of water, it is ready for transport, which can be done either with its own machine or with the help of a tug.

Vessel 1 is intended mainly for pulp bundles, but other timber can also be transported on it. A vessel suitable for pulp bundles can be about 100 m long and 25 m wide, in which case it has two Λ partitions. The distance between these is then approximately 7 m, which corresponds to the width of one double bundle.

However, the invention is not limited to the construction described above and illustrated in the figures, but can be modified within the scope of the appended claims.

Claims (2)
