Dongfeng Flatbed Carrier Loading Platform Car Tow Truck

The supporting arm and lifting arm of the obstacle removal vehicle are all made of high-strength steel plates, which are formed by bending. Carbon dioxide automatic protective welding only allows two welds, with few welds, small deformation, high precision and strength, and ultrasonic weld detection. Carbon dioxide shielded welding and argon arc welding are adopted for the welding of the obstacle removal vehicle. The weld length is more than 300 mm. Automatic seam welding is adopted to make the weld surface smooth and beautiful.

Heavy duty is a remarkable feature of the development of the obstacle removal vehicle technology. With the adjustment of China's heavy truck tonnage, the construction of China's western development, South to North water and West to East gas transmission, the spread of the Olympic construction and the start of the construction of the Shanghai World Expo, the improvement of road conditions, the development of the transportation industry, and the development of highway transportation towards high-speed, intensive, specialized and containerized, will inevitably lead to the rise of the heavy truck industry (including dedicated heavy trucks). As an obstacle removal vehicle to ensure smooth roads, non condensing vehicles must also be heavy-duty to meet the needs of heavy vehicles for obstacle removal.

It is often said that 3 tons, 5 tons, 8 tons, 20 tons and other specifications of obstacle removal vehicles actually refer to the level of bearing capacity of the chassis used by this type of obstacle removal vehicle. It has a certain relationship with the total mass of the towed vehicle in terms of capacity, but there is no inevitable connection. The larger the tonnage, the greater the operating capacity of the obstacle removal vehicle.

According to the structural type, the obstacle removal vehicles are generally divided into four series, namely, lifting separation type obstacle removal vehicles, lifting linkage type obstacle removal vehicles, flat type obstacle removal vehicles and ordinary type obstacle removal vehicles. Among them, there are two types of lifting separation type obstacle removal vehicles, namely, boom rotating obstacle removal vehicle and non rotating obstacle removal vehicle.
