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.

When removing the entrusted (towed) vehicle from the site, the obstacle removal vehicle generally adopts two methods: towing and supporting. Towing is to use the arm of the wrecker to lift the vehicle and drive it. Towing is often referred to as "hard towing", which is to use the obstacle removal vehicle to be towed by the trailer.

Obstacle removal vehicle is a special engineering vehicle designed to ensure smooth roads, and is an important equipment for traffic management in prosperous urban areas and highways. It can quickly, timely and safely remove accidents, faults and illegal vehicles on the road, and dredge special vehicles for road traffic.

The full name of the obstacle removal vehicle is road obstacle removal vehicle, also known as trailer, road rescue vehicle and towing vehicle. It has multiple functions such as lifting, pulling, lifting and towing. The obstacle removal vehicle is mainly used for road fault vehicles, urban vehicles against rules and emergency rescue. Obstacle removal vehicles are mainly divided into: trailer connected type, trailer separated type, one trailer type, flat plate one trailer type, multi-function obstacle removal vehicle and hydraulic automatic clamping type.
