Product Description

Hoisting Crane Mobile Crane 70 ton Truck Crane QY70KH with Lifting Height 62.5m

More excellent performance
1. The optimizing layout of the machine makes the stress of the main bearing carriers more reasonable, and the lifting performance is higher than the products with the same tonnage.
2. Apply the mature jib technique which integrates plug-in boom head, embedded boom block, and special telescoping mechanism, which makes the jib more stable and reliable.
3. Optimize the stress design. Adopt the box-type outriggers which have larger span, stronger rigidity, and better stability.
More reliable quality
4. Adopt the classic K series jib telescoping technique, working safer and more reliable.
5. Make the most complete safety device system in the industry, ensuring the lifting safer and more reliable.
6. The comprehensively upgraded brake system adopts double circuit air pressure design. Multiple systems ensure the brake safety of the truck during travel.
7. The new power steering mechanism adopts hydraulic power design, which makes the steering light, flexible, and precise, and ensures the safety of the truck.
8. The intensity and rigidity of the rotary table and frame structure with high rigidity are completely coordinated.
9. The perfect integration of the design and structure realizes the automation of welding, which is more reliable.
Easier to operate
10. The high efficient and energy efficient load sensing hydraulic system is sensitive to operate and precise to control, having good slight mobility.
11. Optimize the control levers, which is easier to operate.
12. The cab adopts orthodrome front windscreen, having wider operating views.
Easier to maintain
13. The optimizing design of the pipeline traces makes the layout more scientific and reasonable, greatly reducing the dismantling and installing time of the pipelines and the maintenance expense.
14. Completely upgrade the electrical system. Adopt anti-creep connector clips, greatly prolonging the service life of the parts.
15. Adopt K series rope anti-disorder technique, improving the lifting efficiency, reducing the labor intensity, and prolonging the service life of the steel rope.
16. The telescoping steel wire rope oriented and protective device avoids the steel wire rope out of the track and broken.
17. Fully covered walking plate supplies a platform for the maintenance, and effectively protects the parts of the machine.
More energy-efficient and environmental friendly
18.  Adopt double industrial automation control engine, featuring strong power and energy efficiency.
19. Under the economical mode, it can meet the engine power requirement of the normal lifting work. Under the high power mode, it can meet the requirement of the high challenge and high efficient lifting work.
20. Adopt the high power radiator, avoiding the system from bad cooling, solving the problem of oil overheating, and prolonging the service life of the hydraulic oil.
21.  Adopt the advanced matching technique, which makes the design more scientific. It can reduce the consumption of the mechanism, prolong the service life of the machine, and has high residual value.
 

QY70KH Truck crane is widely used for the lifting operations in general engineering projects, such as construction site, urban renewal, communication and transportation, ports, bridge, oilfields and mine, and complex working environments.

 

* 48 m super boom, stronger performance in high-frequent use working conditions

Five-section boom of 48 m has the lifting performance of 8% over the cranes in its class and 10-15% higher when the boom is partially and fully extended and used frequently.

 

* Optimal power transmission system

Off-road specialized four-axle G-class chassis with low speed large torque power transmission system equipped, features higher climbing capacity at lower speeds and job site transfer capacity at higher speeds, i.e. maximum grade ability 41% and a maximum travel speed of 90 km/h.

 

* Exclusive control technology of simultaneous movements, more efficient

G1 generation double-variable pump along with after-valve compensation load-sensitive system contributes to fine control of lifting operation, smooth operation and industry-leading working efficiency, leading to economical, efficient and precise control.

 

* High grade electrical protection, more reliable operationImproved electrical system reliability: waterproof and dustproof inserts, high temperature-resistant corrugated pipes, special wire harness closure sleeves and rubber sleeves are used, excellent dust protection, protection level up to IP67.
