The system consists of upper and lower ring beams, hydraulic cylinders, and a PLC control system. Significant improvements under the pre-ballast lifting working conditions.The max lifting capacity of a single pile of the system can reach 10,000 tons, and the maximum operating water depth is 120 meters. It is suitable for all types of truss-leg self-elevating platforms.

Smooth and accurate lifting and lowering, adapt to frequent starts. It has obvious advantages in terms of safety and efficiency.The system uses hydraulic power loading and is equipped with a double-step automatic upper and lower mechanism. By utilizing the synchronous actions of the upper and lower cylinders, it can rapidly improve the lifting and lowering efficiency of the platform. The average lifting and lowering speed of the platform can reach 60mm/min, which can fully meet the platform requirements. The system can adapt to frequent starts and brakes, providing powerful technical support for the frequent lifting and lowering operations of the platform.
