QY50KD truck crane is the product with high reliability inheriting classical and advanced technology about design and manufacture
truck crane of many years and based on mature technology. Special truck crane chassis designed and manufactured by our company,
all covered working surface and classic K-series appearance outline are equipped.
The operations of crane are very simple, convenient and flexible. It is widely use for lifting operation and installation work in
urban renewal, transportation, ports, bridges, oilfield, industrial and mining enterprises, etc.
Truck crane is widely used for the lifting operations in general engineering projects, such as construction site, urban renewal,
communication and transportation, ports, bridge, oilfields and mine, and complex working environments.
* 5-section boom of 44m with U-type profile is adopted; the max. lifting load is 50 t; the max. lifting height is 59.5 m; all
capacities take the lead in its class.
* The machine is designed to be high temperature resistance, so it can continuously work without downtime in ambient temperature
of 45ºC. The whole vehicle is also waterproof and corrosion resistant. The reliability and service life of parts are greatly
improved.
