Belgium primarily based REM-B Hydraulics has developed a hydraulic shackle release powerpack primarily based on Enerpac’s cordless XC-Series hydraulic pump for connecting and releasing 1000 tonne, 85 m high, offshore wind turbine bases throughout quayside lifting onto a pontoon.

REM-B Hydraulics developed the powerpacks for worldwide metal development company, Smulders. The self-contained, remote-controlled hydraulics powerpacks are a safer alternative to lengthy lengths of hydraulic hoses connected to a quayside pump.
Lifting 85m high fabricated turbine bases from the quayside on to a barge for shipping offshore requires shackles to attach the turbine base to a three-point lifting body and crane. Engaging and releasing the shackles is completed utilizing a double appearing valve arrangement powered by quayside pump related by long hoses. Smulders was on the lookout for a simpler and safer method of participating and releasing the shackles without the necessity for lengthy hoses.
Attached to every leg of the lifting body, the REM-B Hydraulics’ system removes the requirement for long hoses through the use of a battery-powered, Enerpac XC pump to function a bi-directional valve connected to a cylinder that moves the pin connecting the shackle. The whole system is contained in a compact steel case with an external aerial linking each unit to a wireless controller. For elevated ไดอะแฟรม , the shackle pins are activated sequentially.
Weighing 9.9 kg, the Enerpac XC-Series hydraulic pump is supplied with an efficient electrical motor powered by an industrial grade 28-volt, Lithium-Ion battery, delivering exceptional speed and run time and is designed for remote out of doors locations.
