Ship landing structure

The ship's landing steps usually extend at the level of the ship's superstructure deck, from the upper deck on the ship's side down to the berth. If the ship has a suitable superstructure deck with a height of 6 ... Θ m from the main deck, it is possible to leave the ship even during low tide along these steps without special measures. After all, the ship's side height in cargo is usually of the same order of magnitude more than 0.5 m as berth heights during high tide, and the tide height variation rarely exceeds 6 m. If there is no suitable superstructure, which is normal, especially in 15 small ships under 150 m long, the tide as the landing descends below the quay level to build a new multi-man connection to the quay after the old demolition; when the water rises again, a counter-20 action is necessary. This is necessary in order for the ship's loading / unloading to continue uninterrupted, but it is otherwise desirable for the ship and the berth to remain connected.

The present invention eliminates said drawback. It provides a continuous connection from fixed steps on board to the upper level of landing steps on the side of the ship. It is characterized by the features further defined in the claim.

Figure 1 shows the situation during high tide as seen from pier 30 and

Figure 2 is a situation during low tide when viewed from the ship.

Figure 3 shows a sled according to the invention: a) from behind, b) from the side and c) from above.

35 During high tide, the situation is normal. The connection between the deck 5 of the ship and the berth 6 takes place along the landing steps 8 at the height of the deck or side edge, as shown in Figure 1, from the upper deck 9 65745 on the side of the ship.

Figure 2 shows a situation during low tide essential to the invention. The landing stairs 8 and their upper platform 9 rest on the pier 6. The upper level is ascended by fixed steps 7 in the ship 5.

Fig. 3 shows an embodiment of the structure according to the invention, which enables the upper level of the descent stairs to rise from the height shown in Fig. 1, relative to the fixed stairs, upwards during low tide.

10 The thighs of the fixed steps are made of a U-rail 2, to the other flange of which the steps are attached, the u-chutes point towards the center line of the step, so they can be used as guide gutters for eight wheels 4 of the carriage 1, four of which allow the carriage 1 to move the other four, first, block at this plane of the sled and, second, only allow translational movement parallel to the centerline of the sled at this plane. The upper level of the landing steps is connected to the carriage by a rigid shaft 3 and any supports required by the shaft. The upper plane can thus move translationally with respect to the fixed steps and only in the direction of the thighs of these steps.
