Each of the rails 3 may have a slot 3b. Each of the rails 3 may also have transverse bracing plates 3a as indicated in the figure. The rails 3 are arranged so that the slots 3b of each of the rails 3 is facing each other.The carrier construction 1, 2 comprises several sliding parts 2 and a davit carrier 1. The number of sliding parts 2 being transversely arranged between the rails 3 so that each end 2a of the number of sliding parts 2 protrude into the slots 3a of the rails 3. The number of sliding parts 2 is adapted to slidingly move within the rails 3 in the longitudinally direction of the rails 3. The figure indicates three sliding parts 2. This number may however vary in different embodiments of the invention.The davit carrier 1 of the carrier construction 1, 2 is suspended from the sliding parts 2. The davit carrier 1 and sliding parts 2 may for instance be connected through a bolted connected 1a, 2b. This is indicated in the figure by ears with openings 2b in the number of sliding parts 2 and in corresponding number of ears with openings 1a in the davit carrier 1. The davit carrier 1 may comprise several plates 1b corresponding the number of sliding parts 2. Each plate 1b is suspended from a respective sliding part 2. The number of plates 1b are however mutually connected to form a rigid structure underneath the number of sliding parts 2.The davit arrangement 10 further discloses a winch arrangement 5. The winch arrangement 5 is suspended beneath the carrier construction 1, 2. The winch arrangement 5 is further connected to the davit arm 6 and is thus adapted to be movable related to the carrier construction 1, 2. The winch arrangement 5 is further adapted to be connected to a boat A, B for launching and/or hoisting this to and from a suspended position to a storage position or sea surface.The davit arrangement 10 further comprises a shock absorber 11 in connection with the winch arrangement 5 and davit arm 6 to reduce the impact of forces acting on the davit arrangement 10. The shock absorber 11 is known per se. The davit arrangement 10 further comprised a cylinder arrangement 4. In the figure is arranged a cylinder arrangement 4 on each side of the davit carrier 1. Each of the cylinder arrangements 4 are connected to each of the rails as illustrated in the figure 1.In the following one of the cylinder arrangements will be described in detail. The cylinder arrangement 4 comprises a cylinder 4 attached to the rail 3 through a bracket 8 as indicated in the figure 1. The bracket 8 may be fixedly connected or integrated in the rail 3. The figure indicates that the bracket 8 is arranged at the underside of the rail 3. The bracket 8 represents a fastening mechanism between the cylinder 4 and the rail 3 and may be performed in other ways than through a bracket 8.The cylinder 4 is arranged in parallel with the rail 3. The cylinder 4 is in a distal end 4a connected to the davit carrier 1 through a second bracket 7. The second bracket 7 is further fixedly attached or integrated with the davit carrier 1. The cylinder 4 having at least one further cylinder 4d, 4e arranged within the outer cylinder 4c, the cylinders 4c, 4d, 4e being telescopically and slidingly connected as will be described further related to relevant figures. The number of telescopic cylinders within the outer cylinder 4c is not limited to 2. However, any suitable number is possible.Figure 2 discloses a detailed view of the davit arrangement 10, viewed from behind. The figure illustrates how the different features described above, are connected together. The davit carrier 1 with the davit arm 6 is suspended from the sliding part 2. On each side of the carrier 1, there cylinders 4 are positioned. The cylinders 4 are suspended from the rails 3. The cylinders 4 are further connected in one end to the davit carrier 1 and in a second part to the rails 3 so that the telescopic cylinders 4 may slide the davit carrier 1 in the longitudinal direction.Figure 3-6 shows a detailed view of the cylinder arrangement 4 of the davit arrangement according to the invention, viewed from the side. The davit carrier 1 is arranged respectively in the intermediate position (fig.3-4) and in the storage position (fig.5-6).As seen particular in figure 4 and 6, the cylinder 4 comprises one or more cylinders 4d, 4e arranged within the outer cylinder 4c. The inner cylinder(s) 4d, 4e are thus slidingly arranged within the outer cylinder 4c.As previously mentioned, the outer cylinder 4c is fixedly connected to the rail 3 through the bracket 8. It is indicated in the figures that the outer cylinder 4c is connected a distance from a free end of the outer cylinder 4c. However, the cylinder 4 may be connected in various positions to the bracket 8. It is also possible to connect the cylinder 4 to the rail 3 by other fastening arrangements than through a bracket 8, for instance a direct connection between the rail 3 and cylinder 4.The innermost cylinder 4e is connected to the davit carrier 1 through the second bracket 7 as illustrated in the figure. This connection may also be performed by other connection arrangements that a bracket 7, for instance a direct connection between innermost cylinder 4e and the davit carrier 1.Figure 3-4 illustrates the davit arrangement 10 in the intermediate position. In this position the davit arm 6 and the cylinder 4 is retracted in the most compact position. The inner cylinder(s) 4d, 4e is in this position arranged fully retracted into the outer cylinder 4c.Beneath the davit arrangement, the two or more boats B and A that may be operated by the davit arrangement, is illustrated.Figure 5-6 illustrates the davit arrangement 10 in the storage position. In this position the cylinder 4 is extended in its full length by moving the inner cylinder(s) 4d, 4e out of the outer cylinder 4c. This movement will result in a movement of the davit carrier 1. As a consequence, the whole davit carrier 1 will move inwards, ie in the opposite direction of the davit arm 6. In this position, the boat may be lowered and stored in a parking area directly that is arranged to store the boats that are hoisted from the sea. The boats B, A are illustrating the boats that may be handled by the davit arrangement 10 to the parked/retrieved or launched/hosted.Figure 7-10 shows the functioning of the davit arrangement illustrated by a twopoint davit arrangement.Figure 7 shows the two-point davit arrangement 20 made up by two telescopic arrangement. The figure shows the arrangement viewed in front of the arrangement, ie from the position where the boat(s) are launched into the sea. Each of the telescopic arrangements comprises a davit carrier, sliding parts winch, beams and cylinders similar as described in relation to figure 1-6.Figure 8 shows the two-point davit arrangement 20 viewed from above with two boats A, B arranged beside each other in the storage area beneath the davit arrangement 20.Figure 9 illustrates all the three possible positions of the davit arrangement 10, 20 together in one figure. It is to be noted that this is not a correct image of the davit arrangement 10, 20 as the davit carrier 1 will move inwards when the cylinder 4 being extended. The figure thus illustrates only the different positions of the davit arrangement 10, 20. To distinguish the features arranged in the innermost position and launching position from the intermediate position, the reference number of the winch arrangement and the davit carrier positioned in the storage position have been given the reference number 5’’ and 1’’. The boat, the winch arrangement and the davit arm positioned in the launching position have respectively reference number A’, 5’ and 6’. The features are the same features as the features with numbers 5, 1, A and 6, the difference is the positioning.The figure shows how the davit carrier 1 is moved inwards facing away from the sea area. The boats may by this movement be transported inwards into different storage positions of the boats in the parking area directly. As indicated in the figure 9, the boat B may be lowered onto a boat crib 21 when parked or stored. The figure indicates that the boat A is positioned and parked beside the boat B in a separate and similar boat crib 21 in the parking area. The boat A is arranged at the side facing the sea area.In the launching operation, the boat A is hoisted from the crib 21 by the winch arrangement 5. The boat A is further transported to a launching position. In the launching position, the davit carrier 6’ is extended to the outermost position as shown in the figure. The travelling distance for the boat from A to A’ by the davit arm 6 is defined as the standard davit outreach. In this launching position, the boat A’ is suspended above the sea surface and may be lowered into the sea by the winch arrangement 5' and released from the winch arrangement 5.The davit arm 6 may then be retracted again into the davit carrier 1 until fully retracted. From this intermediate position, the cylinder(s) 4 may extend in the opposite end and move the davit carrier 1 inwards from the position indicated by reference number 1 to reference number 1’’, to position the winch arrangement 5 above the boat B or further inwards as indicated with reference number 5’’ to hoist a boat that is arranged in the parking area. The davit carrier 1 is adapted to move a distance referred to as the extra inboard travel in figure 9.Figure 10 shows the steps repeated for boat B from the storage position to a launching position of the boat B.The procedure will thus be that the one or more cylinder(s) 4 is moving the davit carrier 1 inwards by extending the cylinder(s) 4 as described above. The slidable part 2 attached to the davit carrier 1 is at the same time moved in the longitudinal direction of the beams 3. When the winch arrangement 5’’ is aligned with the boat B, the boat B is secured to the winch arrangement 5’’ and lifted from the crib 21. The cylinder(s) 4 is retracted in the opposite direction, resulting in a movement of the boat B towards the intermediate position where the cylinder(s) 4 is fully retracted. When reaching the intermediate position, the davit arm 6 is extended out from the davit carrier 1. When the davit arm 6’ is fully extended, the boat B’ is suspended above the sea surface. The boat B’ may then be lowered into the sea.By this davit arrangement 1, several boats may be lifted directly from their storage position one by one as described above, and launched to the sea without any intermediate arranging of each of the boats.
