Crawler Crane(QUY50A)
Introduction of Crawler Crane(QUY50A):
Crawler Crane(QUY50A) is designed and developed independently in absorption of foreign advanced technology and combined with China domestic work conditions. It features hydraulic drive, full swing and lattice boom, and also the first one adoption of pilot proportional control in China domestic crawler cranes. This crane is easy operation, stable travel and reasonable arrangement in structure. The maximum lifting capacity is 50t, boom length 13m~52m, jib length 9.15m~15.25m. This crane is suitable for lifting and installation job in construction site, mine, factory and dockside. Optional mechanical grab is available for earth moving and stacking work.
The imported engine with original packing has strong power, and can meet the requirements of high-efficient work.
- Precise matching design with advanced energy conservation control can reduce the oil consumption of the machine.
- Low emission meets the Europe II standard.
- The adoption of new cooling fan and large-scale silencer lowers the noise of the machine.
- The adoption of the advanced turbocharging technique increases the highland adaptability of the machine.
- Automatic preheating system improves the working capacity in the low temperature.
- Unique fan cover with the shape of hopper opening greatly improves the air supply of the engine and the radiating capacity of the system, guaranteeing the successive high-efficient work of the machine.
- Restart prevention system effectively avoids the misoperation, and improve the use security of the machine.
