In offshore jack-up platforms used in offshore energy mining and wind power installations, the lifting system assumes the important task of core operation, and its performance directly affects the safety and use of the platform. Hengli relies on rich experience and strong technical strength to develop supporting offshore jack-up platform lifting hydraulic systems and lifting cylinders. Through the optimization of raw materials and product structure, the products are lighter and smaller; through high integration, the product functions Modular and intelligent, to achieve the purpose of improving efficiency and reducing energy consumption; strictly control the inspection and assembly procedures of hydraulic components, and carry out relevant FAT function tests and third-party inspection organization product classification certification to ensure that the entire system is efficient, safe and reliable.
