Over the years we have been working on many different design & construct projects. This has resulted in a variety of lifting and rigging tools and equipment, like Transition Piece lifting tools, tailing and upending frames, Monopile grippers, lifting beams, spreader bars and Anode Cage lifting tools. These tools are often intensively used by our...
Onshore windturbine in need for a manual installed light weight crane
The new YawHookTM technology allows 800 kg lifts to be performed without the need for a traditional crane on the ground.
The challenge: design a crane which can assembled by hand in onshore windturbine nacelles
LiftWerx asked Eager.one to design a foldable crane that can be mounted and moved manually. The crane needs to be able to lifts 800 kilogram, from 100 m height with a 2.5 m radius.
Eager.one’s engineers came up with the idea to use light weight “trusses”. By putting the trusses together by hand the mast is erected. The crane’s boom is attached by means of a pin in the middle of the mast, allowing the boom to slew with wheels around the mast.

Calculating optimize storage in the onshore wind turbine
Once erected the crane can remove roof panels, exchange yaw drives and lift larger crane systems (like the LiftWerx HeliHook) into the nacelle.
Green engineering
Because of using light weight materials and an electric crane which lifts larger cranes into the turbine, there is no need for traditional cranes.
“It was great being a member of the design team for this tool.”
