Abstract:
1. A lifting arrangement, for launch, retrieval and storage of small floating units on a boat, by carrying out at the same time a pivoting and a translational motion from a railing of the boat when seen in a forwards or in a backwards direction down towards a water surface that surrounds the boat, wherein the lifting arrangement includes lifting arrangement units that act in pairs, each lifting arrangement unit comprising: a frame to be attached to the boat, a link arm system supported by the frame and including a lever, one end of which is united with the frame through a first joint in a manner that allows pivoting and arranged to, through the influence of an actuator, carry out a tipping action forwards and backwards in a vertical plane, an angled lifting arm with a first and a second shank where the first shank is united in a manner that allows pivoting though a second joint with a second end of the lever and where the second shank forms a load-bearing part for the floating unit, whereby the lifting arm is guided during a tipping motion through interaction between a guide that protrudes from the frame and a guide surface formed as a cam curve formed from a downwardly facing surface of the lifting arm.
