Continuous Hydraulic Jacking System

The GustoMSC hydraulic jacking systems are of the positive engagement type, using double-acting hydraulic cylinders. The systems based on the pin-in-the-hole principle operate on smooth circular legs which minimize wave, wind, and current forces both in elevated, transit, and installation conditions with their beneficial hydrodynamic and aerodynamic characteristics. The circular leg guides in the hull and jack-house ensure proper guidance of the legs with hardly any wear. For protection against mechanical damage and environmental hazards, the jacking system is enclosed inside a jack-house.

For lifting speed requirements of over 0.4 m/min the patented Continuous Hydraulic jacking system has the advantages of the classic single-acting system however it equals the speed and operating efficiency of a rack & pinion jacking system. Controls allow for full automatic jacking. The system has proven itself and set the benchmark in the wind turbine installation market where daily fully loaded jacking operations are the norm.

The system design is arranged such that in case of a defect the jacking operations can be continued at reduced speed.
