ZOOMLION 70 ton truck crane QY70V552 price in heavy construction Weichai engine

Product Description

Lifting capacity

1. Continuously overall promotion makes our lifting capacity of crane be improved once and once again

2. 43 m main boom , two section jibs (9.5m . 16m)

3. Optimized central slewing position increases the lifting capacity of the crane over rear

4. Large outrigger span improves the working stability of the crane greatly

5. Adopt internationally advanced structure analysis and calculation methods to develop the lifting capacity of crane deeply 6. Leading boom manufacturing process in trade.

ZOOMLION 70V truck crane, integrating many years’ design and manufacturing experiences and different kinds of high-tech, is a new generation product with high performances, developed independently by our company in accordance with market trend and consumers’ demands. Main technical specifications, such as lifting height, boom length, working speed, lifting capacity, all have arrived the international advanced technical level. The complete vehicle makes a global purchase of complete set of products.
This truck crane is a full slewing, electro-hydraulic proportional control truck crane with telescoping booms. It has the characteristic of economic, excellent performance, flexible working etc. The boom can telescope freely with two working conditions of outrigger full-extend and half-extend. It adopts full-width cab four axles special-purpose chassis made by our company, which is with wide vision, comfortable seats, hydraulically powered steering makes operation convenient and maneuverable. This special-purpose chassis is eight-by-four drive.
Since this truck crane adopts latest load feedback electro-hydraulic proportional reversing valve and dual pump system, the executive body of it can give full play to its working performance. Operation rod can realize the combination motion of boom and jib hoisting, derricking, slewing and telescoping, which is highly increased the crane working efficiency. It has the characteristic of easy and flexible operation, stable working and stepless speed adjustment etc. Various safety devices in hydraulic system, such as safety valve, counterbalance valve, hydraulic lock, brake valve etc., which can avoid accident caused by breakage of oil pipe due to overloading. The control system applies concentration line technology and has fault self-diagnosis function with the full LCD screen, which can timely display the problem pressure and provide fault settlement method.
Besides, there are various safety devices, such as moment limiter, hoisting height limiter and all the necessary illuminator, which can ensure safety & reliable operation and night work.
This crane’s structure is novelty, is the combination of physique elegance, line shape and color beauty.
