<p>The present invention relates to a device at a trailer (1), especially a boat trailer (10), which includes a chassis (1a) supported by wheels (1b) and a coupling device (1f) in the front for connecting the trailer (1) to a towing vehicle. A two-armed lever consists of arms (2a, 2b) which form an angle with each other and is pivoted in an axis of rotation (3) which is oriented transversally at the back of the trailer. The first arm of the lever (2a), which mainly points forward from the axis of rotation (3) has a length that exceeds or falls below the length of the other arm (2b) of the lever. The two lever-arms comprise parallel arm elements (2a1, 2b1; 2a2, 2b2), whose ends are connected to the ends of the axis of rotation and which at their outer ends are linked by transversal beams (2a3, 2b3). A winch tower (6) with a winch (1d) is provided at the front end of the trailer. The wire (1e) of the winch is adapted to run over the outer ends of the lever-arms (2a, 2b) and in its end is provided with lifting means for the object.</p> |
