Zoomlion 12 Ton Truck Crane QY12D431
Feasures
The QY12D431 truck crane, which is developed independently to adapt to the market demands, is a new-generation and high-performance product integrating our company many years' manufacturing experience with advanced technologies. Its performances such as lifting height, boom length, working speed and lifting capacity have achieved advanced international level.
The truck crane, with spacious cabandcompact decoration, adopts full slewing system, 4-section telescopic boom sections, unique manual proportional control system and self-made semi-width special purpose chassis with three axles. 6× 4 drive provides the crane with good driving performance and flexible steering. The engine complies with the National Stage III emission standard.
The system with latest load feedback hydraulic operated proportional directional control valve and quadruple gear pump, and the safety devices fitted in hydraulic system, such as relief valve, balance valve, hydraulic lock and brake valve etc., prevents the oil line from overloading and the accidents caused by oil pipe breakage and makes full use of the working capacity of each actuating mechanism. Thus the reliability and safety of the crane are increased.
Wide cab
Five-segment U section boom
Single cylinder luffing and double-winch
Manual mechanical control
Spacious and luxury streamline cab
U boom system
Constantly optimize the boom section, completely releasing the carrying capacity of the plates, which makes the lifting more reliable and safer.
Compact boom head
Extend the jib length, which can extend the working radius to the most.
Hydraulic pipeline
The pipeline adopts high-precision cold drawing steel pipe, matching with the cutting ferrule, which is good looking and easy to maintain.
Operating cab
It has large space and wide views. The control levers and instrument buttons are at hand.
Torque limiter
The colorful LCD display of the torque limiter can shows all the important operating information.
Engine
Reasonable matching, energy efficiency and environmental protection, and strong power meet the economical running of the required power.
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.
