Zoomlion 55 Ton Truck Crane Qy55V532 Qy550V

Features of Zoomlion 50 ton New truck cranes (QY55V532)

QY55V532truck crane is a new-generation and high-performance product. Its performances such as lifting height, boom length, working speed and lifting capacity have achieved advanced international level.

The truck crane, with spacious cab and luxurious equipments, adopts full slewing system, telescopic boom, hydraulic proportional control system and self-made full-width special purpose chassis with four axles. 8× 4 drive and hydraulic power steering mechanism provides the crane with good driving performance and flexible steering.

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 to makes full use of the working capacity of each actuating mechanism. Thus the reliability and safety of the crane are increased.

The safety devices: Load moment limiter, and the complete lighting system
