<p>The invention concern a lifting arrangement, intended for the launch, retrieval and storage of small floating units on a boat, by carrying out at the same time a pivoting and a translational motion in a forwards or in a backwards direction. For easy and safe handling a floating unit at a leisure boat, it comprises a frame (6) intended to be fixed attached to the boat, a link arm system (5) including a lever (10), which through a joint (17) allows pivoting and through the influence of a control and actuator means (13), carry out a tipping action forwards and backwards, an angled lifting arm (12) with a first (12') and a second (12") shank, whereby the lifting arm (12) is guided during the tipping motion through interaction between a guide (20) that protrudes from the frame and a guide surface formed as a cam curve (21 ) formed from a downwardly facing surface of the lifting arm.</p> |
