Description

The present invention relates to lifting equipment for ships according to the preamble of claim 1.

5 -

Today, boats use winches or similar wire-operated lifting devices to lift and lower an inflatable boat or other small boat. They are cumbersome to use and require at least two people to raise or lower the auxiliary boat. In addition, an auxiliary boat today often has to be stored on a deck where it takes up a lot of space.

It is an object of the present invention to obviate the above drawbacks. The lifting device according to the invention is mainly characterized in that the lifting arms are two on top of each other and that the lifting arms are attached to the upper and lower ends of the vertical supports.

20 The auxiliary boat can be driven directly to the • •:: ·· platform in the system and lifted by an electric motor. With the apparatus according to the invention, it is possible to raise and lower the auxiliary boat alone. In addition, the auxiliary boat may be stored on a platform in which: 1 2 · '· it does not take up space on the deck.

In the following, the invention will be described in more detail by means of a prefix with reference to the accompanying drawing, which shows a lifting apparatus according to the invention. ***** ··· • »• · • · e 30 The hoisting equipment has a base 1 on which the auxiliary boat can be driven. The base 1 consists of two gentle V-shaped shapes. 1.L1 • · «e from the frame beam 2, which also has a sloping V-shaped: 1 ·. ·« · Vertical support 3. In addition, the base 1 has two • f | · ·. ··· selective supports 4 the front of the base and rear edges when viewed in the direction of the frame beams 2 • 35.

The base 1 is raised and lowered by four lifting arms 6, ^ 5 of which always two are superimposed and fastened to the same vertical support 3 by means of a screw and a nut. The lifting arms 6 are attached, at one end, to perforated, vertical fastening beams 7, by means of which the equipment is fastened to the stern of the boat from the holes 8 at the upper ends of the beams 10. The fastening beams are bent gently towards the stern of the boat.

The lifting arms 6 are in the shape of a gentle V downwards. The upper lifting arms 6 are supported on each other by intermediate supports 15 9. Correspondingly, the lower lifting arms are supported on each other. In addition, there are vertical supports 10 between the upper and lower lifting arms. The intermediate supports 9 are supported by angled brackets 11. The lifting arms are moved by an electric motor 12 by means of a rotatable threaded screw 13 fixed to the upper end of the second mounting beam.
