Boat trailer for motor vehicles has buoyancy bodies at the back, inflated for launch and withdrawal of trailer from water

摘要

The trailer has a carriage (1), and a boat is held on it via winch and holder at the front, and slip roller pairs at the back. One or more inflatable buoyancy bodies (4A,B,5A,B) in the rear area of the carriage extend under it when inflated. In transportation direction, the bodies are held on horizontal pivot levers (40A,50A) on the plane of the carriage, while in loading/unloading position, they are pivoted down and backwards, and are held by the levers, which are now in vertical position. The buoyancy bodies are connected via a valve (33) to a compressor (3). This is connected to an electric motor, which in turn is connected to the electrical system of the towing vehicle.
