[0002] In the field of road cargo transportation, especially in the open-air transportation of bulk cargo, building materials and the like, covering the truck carriage with a tarpaulin is a necessary operation link to prevent the cargo from scattering, losing and being eroded by rain.

[0003] At present, the vast majority of the industry still adopts the traditional manual laying method, in which operators need to carry heavy tarpaulins to climb to the top of carriages several meters high, and manually perform operations such as unfolding, pulling and positioning. The whole process is low in efficiency, time-consuming and labor-intensive (usually requiring 2-3 people to cooperate to complete, taking more than ten minutes); moreover, there are obvious safety hazards, and working at height is easy to cause operators to slip and fall, resulting in personal injury accidents. In addition, the tarpaulin itself is heavy and has strong wind resistance, making operation particularly difficult in bad weather, and the tightness and standardization of the covering are highly dependent on the experience of the operators, so it is difficult to ensure consistent effects.
