It is a walking type crane, also known as auto crane. Lifting motor is widely used in transportation, construction, oil fields, mines, docks and the Department of defense, is particularly applicable to the goods scattered, narrow space, cargo lifting height in construction site. Automobile crane is a variety of construction important device that is widely used, which reduces the labor intensity, save manpower, reduce construction cost, improve the efficiency of construction, ensure project quality, achieve construction mechanization plays a very important role Automobile crane is a variety of construction important device that is widely used, which reduces the labor intensity, save manpower, reduce construction cost, improve the efficiency of construction, ensure project quality, achieve construction mechanization plays a very important role.
