In 2012, China National Heavy Duty Special Vehicle Corporation formulated the task index of 3000 engineering vehicles and 600 tractors with long heads to achieve mass production of 30 new construction vehicles and long-haul tractors. Process preparation.
In order to form the batch production capacity of 30 construction vehicles and long-haul tractors, the technical department of China National Heavy Duty Truck Co., Ltd. actively designs and adapts the workshop workshop equipment, interior assembly trolleys for 30 construction vehicles and long-haul tractors. . After scientific planning, careful design, positive innovation, repeated verification and many improvements, the improvement of the tooling design for the 30 construction vehicles and long head vehicles was finally completed in mid-January 2012. In the recent validation of small-scale production of 30 engineering vehicles, these tools meet the production requirements and have stood the test. 
Heavy truck tractors are equipped with a newly developed long-distance car cab and engine with independent intellectual property rights. All front axles are equipped with disc brakes. The frame uses high-strength steel plates and can be equipped with AMT mechanical automatic transmission.
