[0036] Once the rescue vehicle arrives at the accident scene, the lifting cylinder's jacking rod will lift the lifting arm, and the hook can be used to lift damaged parts or move the accident vehicle to the outside of the road to complete the clearing work.
[0037] The replacement parts can also be lifted by the boom, providing better maintenance conditions for the malfunctioning vehicle and enabling it to return to operation as soon as possible.
