Belgium based REM-B Hydraulics has developed a hydraulic shackle launch powerpack based on Enerpac’s cordless XC-Series hydraulic pump for connecting and releasing one thousand tonne, eighty five m excessive, offshore wind turbine bases throughout quayside lifting onto a pontoon.

REM-B Hydraulics developed the powerpacks for worldwide metal building company, Smulders. The self-contained, remote-controlled hydraulics powerpacks are a safer alternative to long lengths of hydraulic hoses connected to a quayside pump.
Lifting 85m high fabricated turbine bases from the quayside on to a barge for transport offshore requires shackles to attach the turbine base to a three-point lifting body and crane. Engaging and releasing the shackles is finished using a double appearing valve arrangement powered by quayside pump linked by long hoses. Smulders was looking for a simpler and safer method of engaging and releasing the shackles with out the need for long hoses.
Attached to each leg of the lifting frame, the REM-B Hydraulics’ system removes the requirement for long hoses through the use of a battery-powered, Enerpac XC pump to operate a bi-directional valve connected to a cylinder that moves the pin connecting the shackle. The complete system is contained in a compact metal case with an external aerial linking each unit to a wireless controller. For increased safety, the shackle pins are activated sequentially.
Weighing pressure gauge 10 bar , the Enerpac XC-Series hydraulic pump is provided with an environment friendly electric motor powered by an industrial grade 28-volt, Lithium-Ion battery, delivering distinctive speed and run time and is designed for remote outside locations.
