Manufacturer
Changsha Zoomlion Heavy Industry Science & Technology Development Co., Ltd
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.
New sliding design for bracing support, side hydraulic luck
Side hydraulic luck, avoiding heavy crash during the operation, ensures security.
Anti-slew steel wire
Longevity of service for the anti-slew steel wire, ensures the security of the lifting.
Moment Limiter and Display
Automatic moment limiter has the function of self testing and alarming.
Major boom head and slider
1、Hexagon major boom adopts low alloy and high strength structure steel
2、The slider with national patent, flexible operation, logical strength distribution. Strong lifting capability.
Hydraulic Motor
1、Supercharged inter-cooled engine, capable for working at place over 4500 meters altitude.
2、International dominant variable amplitude mechanism, to make the mast close or leave the machine in parallel.
3、Three section, foldable, box shape design mast, with outstanding intensity and strength.
4、The hydraulic system is efficient, energy saving, accurate on the ratio operation, load transmission, load sensitivity control.
