The main components of the imported hydraulic system (balance valve, multi-way valve, oil cylinder, etc.) are used to provide effective and reliable guarantees for the entire process of towing.
Plasma CNC cutting machine, CNC wire cutting machine, and shearing machine are used to cut materials to ensure high precision of the plates, and various specifications of metal structural parts are produced. Gas shielded welding (automatic or manual welding), assembly line assembly, and multiple inspection and testing lines are used to test each assembly or special mechanism of the towing vehicle to ensure that the factory products meet various design requirements;
The new technology of foreign towing vehicles is adopted, with full computer graphic design, reasonable structural design, and convenient use and maintenance. It is a common structural model among towing vehicles.

All welding parts of the vehicle are completed on the fixtures and fully positioned, thus ensuring the quality and process requirements of the product, reducing the weight of the vehicle and increasing the lifting and loading capacity.
All steel components are pickled to prevent the components from rusting for a long time, thus greatly extending the service life of the parts;
The plate cutting of metal structural parts adopts contour cutting, CNC plasma cutting, and shearing machine;
The support arm and the boom are all made of high-strength steel plates, which are formed by bending; carbon dioxide automatic protection welding, the boom only allows one weld, with fewer welds, less deformation, and high strength, and the valve is tested by ultrasonic welds; the machining, welding, and assembly of all finalized products are completed on the fixtures and fixtures, thus ensuring the quality and interchangeability;
All welding adopts carbon dioxide protection welding and argon arc welding, the weld length is greater than 300mm, and automatic welding is adopted, which not only ensures that the weld strength is not lower than the parent material strength, but also makes the weld surface smooth and beautiful.
