发明名称 Motor vehicle and boat trailer
摘要 An automobile/boat trailer for transporting an automobile with a boat supported above the automobile. Four corner vertical support columns are mounted on a trailer having standard rails for supporting an automobile. A boat trailer cradle is mounted so as to be vertically slidable along the support columns. Cables are attached to the trailer cradle and pass over pulleys secured to the top of each column. The cables are secured at their other ends to a winch for raising and lowering the boat cradle. Safety locks are provided for preventing the lowering of the boat cradle if the cables fail to support the cradle.
