By the early 1980s, various pavement construction machinery had formed a complete range of serialized products. After that, although new models emerged from time to time, the main development feature was continuous improvement and enhancement of local components of existing machinery. This was mainly manifested in the extensive adoption of hydraulic drive technology and electronic technology to achieve mechatronics, improve the degree of automatic control, improve the mechanical operation performance and comfort, improve the construction quality, and reduce environmental pollution. During the use of pavement construction equipment, it needs to be transported. In the prior art, a towing device is mostly used for the transportation of the equipment.
