XC-Series Battery-Powered Hydraulic Pump
Challenge
Steel construction company Smulders manufactures offshore wind turbine tower bases. They wanted a better way to lift the 1000 tonne, 85m high, turbine bases from the quayside onto pontoons for shipping. More specifically, they needed a simpler and safer method of engaging and releasing the shackles without using long hoses trailing down to the quayside.

Solution
The engineering team at Belgium-based REM-B Hydraulics developed a system to engage and release the shackles on a three-point lifting frame. Self-contained units were developed for attaching to each leg of the lifting frame. Within each unit is an Enerpac XC-Series cordless battery-powered hydraulic pump, and a bi-directional valve connected to a cylinder. The cylinder is activated by the hydraulics, which moves the pin connected to the shackle. External aerials on each unit connect to a remote wireless controller. For increased safety, the system allows the shackle pins to be activated sequentially.
Benefits
- Simplified the use of shackles
- Reliable and efficient method provided improved lift safety
- Remote operation – units controlled from a safe distance
- No long hydraulic hoses – reduced trip hazard
- No power cable required – reduced trip hazard
