QY50V532 Truck Crane
The QY50V532 truck crane is one of our new generation products developed independently to satisfy market demands. Designed with advanced technology and plentiful production experience of decades in this filed, it offers preeminent performance reaching the international level on lifting height, boom length, working speed and lifting capacity.
Equipped with capacious operating cabin, this truck crane adopts a series of superior devices matched it, such as full slewing system, telescopic boom, hydraulic proportional control system, independently-developed full-width chassis for special purpose with four axles, etc. Additionally, the utilization of 8×4 driving and hydraulic power steering mechanism makes great improvement of driving performance and flexible steering.
Aside from latest hydraulic proportional directional control valve for load feedback and quadruple gear pump, this truck crane also adopts a range of safety devices to match with the hydraulic system, such as relief valve, balance valve, hydraulic lock brake valve, load moment limiter, complete lighting system for night work, etc.
It effectively avoids the overloading of oil pipeline, even breakage of oil pipe to cause serious problems. Furthermore, the machine gets every executive device fully utilized based on the working capacity. It offers higher reliability and safety for operation.
