<p>The trailer for carrying heavy weights and large plates can be folded when it is empty. It consists of a rigid fixed platform to support the load, a super-structure and a hook for lifting it. The superstructure, that ensures the stability of the load, can be folded away on to the platform when the trailer is empty. The hook can be used for lifting the trailer when it is folded as well as when full.</p> |
