The truck crane is a device for lifting, returning and lifting cargo by hydraulic lifting and telescopic system. It is usually assembled on the cargo, generally consisting of cargo chassis, crane, operating device, hydraulic system, device and hydraulic support. It consists of legs, etc. It has many functions such as lifting, freight transportation, etc. According to the boom, it is divided into folding arm with hanging arm and straight arm with hanging; according to the tonnage, it is divided into 2 tons, 3.2 tons, 5 tons, 6.3 tons. 8 tons, 10 tons, 12 tons, 16 tons; according to the chassis: Dongfeng truck crane, liberation truck crane, Auman Futian truck crane, heavy crane, etc. as a kind of lifting and transportation Efficient lifting and transportation equipment, with the advantages of fast, flexible, efficient, convenient, loading and unloading transportation as a crane. Due to the high cost of foreign labor, it emphasizes work efficiency, and the construction basically does not use manual loading and unloading.
Dongfeng truck-mounted cranes have flexible market and mature technology, and have broad market prospects in the international market. At present, foreign truck-mounted cranes have formed diversified product functions, serialization of series, performance (electromechanical and hydraulic gas) integration, etc. The product structure of the multi-directional system is not only used for ordinary lifting operations, but also widely used in various industries such as aerial work, bridge maintenance, high-altitude wiring and inspection. At present, the main enterprises that produce cranes abroad are Sweden HIAB, Austria. PALFINGER company, Italy FASSI company, etc. are all distributed in Europe. The product structure of the crane with the crane is folded arm type, with "multi-joint" and "collapsible", almost all of which are wired remote control and wireless remote control. Optional components, high product convenience and operability. The maximum lifting capacity has exceeded 60, the boom length has exceeded 30, and the maximum lifting torque has exceeded 1KN. The production of cranes in Japan and Korea is also relatively developed. The telescopic boom structure is the main domestic crane industry overview.
