XCMG 75 ton heavy electric hydraulic truck crane QY75K

XCMG 75 ton truck crane model QY75K, Max lift capacity: 75 ton

  • QY75K
  • XCMG
Quantity:

Description:

QY75K is XCMG designed 75 ton truck crane, it is with XCMG designed and produced truck chassis with full wide cab, drive/steer is 8X4X8. All axles steering.

It is with 5 section boom and 2 section lattice jib.

Main features:

1. Advanced boom system

With 5 telescopic arms, optimized U-shaped cross-section, high-strength steel, boom lifting performance in the domestic industry has always been a leading position. Embedded arm, reducing the torsion when the lifting, the next bend, and the slider and the arm point of contact or line contact and so on; plug-in slider to increase the effective length of the boom, can effectively avoid local loss Steady phenomenon occurred.

 

2. The use of hydraulic control system, the operation more stable, reliable and comfortable

The new hydraulic control system design, work efficiency, good heat balance, homework more comfortable and easy to maintain. The lifting system, the winch brake pressure oil from the stable oil source control opening and closing, can be a good match the main valve, balance valve, brake between the three opening and closing characteristics, to avoid hoisting jitter, down, reverse and other failures The

 

3. Combined balance weight and mechanical fastening device

Through the combination of balanced weight combination of multiple modes, the whole machine running state weight to meet the different areas of road driving regulations. The balance of heavy machinery can be fixed to meet the balance of different combinations of mutual fixation, while the frame and the use of multi-point support fixed way, place more convenient and convenient, while ensuring that the balance will not vibrate driving, flip, travel more Efficient, stable and reliable.

 

4. Independent research and development of the full load sensitive technology, smooth operation, good micro-movement

The use of load-sensitive filtering technology can make the system from the load pressure changes and changes in oil pump flow to achieve the requirements of the user speed control to provide system control, but also can reduce the energy consumption of the hydraulic system to reduce the system heat, System life.

 

5. Dedicated telescopic technology to improve the active safety of telescopic system

By the national patent of the boom telescopic control technology, so that the boom automatically in accordance with the provisions of the order of the extension and contraction control, to avoid misuse caused by the cylinder bending, boom broken, improve operational safety. By the national invention patent telescopic cylinder anti-bending technology to avoid the core tube bending, improve the safety of the use of core. Telescopic cylinder balance spool, to avoid balance spool oil, to prevent the retraction of the cylinder.

6. The front axle uses pneumatic disc brake

 

Increase the braking performance, enhance the braking stability, reduce the brake abnormal sound. Simple structure, high reliability, greatly improve the safety of the front axle brake; brake reflection sensitive, adjust the brake clearance is simple, user-friendly maintenance, maintenance costs, the use of low cost

 

7. Full bridge steering system

The use of multi-axis multi-mode steering system technology, the use of a wide range of conditions, steering flexibility increased significantly. Can achieve a small turn, crab, rear axle lock three steering mode, the road, site adaptability.
