Advantages of crane luffing hydraulic cylinder products produced by Qingdao Micro Precision Machinery Co., Ltd.:

1. Compact structural design and use of high-strength materials ensure the lightweight of the cylinder

2. The design has a wide temperature range (-40℃～+100℃), and can provide higher or lower temperature cylinder customization services

3. Theoretical analysis and finite element calculation of the system ensure that the cylinder has a long service life under heavy load.

4. Mature sealing system ensures that the cylinder does not vibrate or crawl at low speeds.

5. Provide a variety of surface anti-corrosion treatment solutions: Ni/Cr electroplating, ceramic spraying, laser cladding, QPQ, etc.

6. The guide sleeve adopts anti-corrosion technology to ensure that the cylinder can tilt for a long time without the problem of rusting of the guide sleeve.

7. Hydraulic locks, load holding valves, sequence valves, relief valves, pressure measuring joints, etc. can be designed and integrated as required.

8. Working pressure, size specifications, installation methods, etc. can be customized according to customer needs.

9. All specifications of cylinders are designed by professional engineers

10. We use high-quality sealing kits purchased from American MPI, Japanese NOK and Swedish SKF.

11. All materials are processed by skilled workers and advanced CNC lathes

12. All hydraulic cylinders are 100% tested before leaving the factory to ensure that each cylinder meets the requirements

13. The hydraulic cylinder is packed in wooden boxes to ensure that the goods reach the customer safely

14. The product has a one-year warranty and provides lifelong tracking service to solve any problems you encounter during use.
