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.

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.
