Description

Lifting system with wire rope on top of two-storey caravan

technical field

The utility model relates to a lifting system with a steel wire rope on a support type double-deck caravan.

Background technique

With the development of the economy and the improvement of people's living standards, the application of RVs has gradually entered the lives of ordinary people. Existing RVs generally have a single-layer structure, which obviously feels insufficient space. Even if there is a double-layer structure, the upper layer is not high enough and only beds can be provided to meet sleeping needs, and it is impossible to stand and walk. If it is designed as a double-layer RV with the upper layer able to meet people's normal life, the total height will reach 5 meters, and it is inconvenient to walk on highways and urban roads.
