The present disclosure is based on the application of the Chinese Application No. 201101114304.9, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present disclosure relates to the field of fire protection equipment, and in particular to a fire truck.

Background technique

Fire trucks, also known as fire trucks, are used exclusively for fire fighting or other emergency rescue. Among them, the high fire truck is a special vehicle for high-altitude rescue or fire-fighting operations. It has a special chassis and a boom on the chassis, which can lift a certain height to meet the rescue needs of high-altitude fires or other emergency situations. Moreover, in order to enrich the function of lifting the fire truck, the end of the boom is usually provided with a demolition device to break the obstacles in the rescue process and facilitate the rescue.
