While offshore wind power is being vigorously developed, whether it is wind turbine or foundation installation, it is inseparable from the wind power installation equipment that transports it to the wind farm site. Also, equipping with lifting equipment and positioning equipment suitable for various installation methods. Hengli has extensive experience in offshore engineering applications, and can provide one-stop solution, including design, production, installation, and global services. In our hydraulic system solution for wind power installation ships, the supporting hydraulic cylinder of the lifting mechanism adopts customized high-strength alloy structural steel, which greatly reduces the weight of the cylinder and improves the strength of the structure. The excellent sealing system enables the internal leakage to reach ≤3ml/24h and guarantees a longer service life.

And we are also designing an auxiliary cylinder to install a displacement sensor externally, which can achieve precise control of the position.    In addition, because the hydraulic cylinder of the lifting mechanism is used in a highly corrosive environment, the long-term exposure of the piston rod can easily cause the surface to be corroded, which can easily cause problems such as scratches on the sealing ring and oil leakage of the hydraulic cylinder. Hengli uses plasma spraying or supersonic flame spraying to spray ceramic coating on the surface of the piston rod to achieve the purpose of improving corrosion resistance and wear resistance.
Hengli has comprehensive global services to help wind power installation equipment complete installation operations quickly and accurately even in bad weather and sea conditions.
