In a horizontal plane, the frame (4) is U-shaped, the ar (4a) outer part (4b) of which works in conjunction with the wheels (6,7) belonging to the rear load-supporting axle. The inner parts (4c) of the arm have a part connecting them which works which a wheel (5) belonging to the front steearable axle. - The support (8) for the boat is raisable and lowerable by means of a hydraulically activated piston and cylinder unit (13). Likewise the support for the aft of the boar is raisable and lowerable by means of hydraulically activated piston and cylinder unit. The boat support (8) comprises an arm (10) rotatably orientated around a rotary axis (11), the end area (10a) of which facing away from the rotary axis supports a support plate (8a) or similar. |
