Reducing cost with crane less solutions

Cranes have always been a critical asset in the wind industry to perform various service activities at the main components. The availability of cranes was defining wind park location, turbines capacity and ground conditions needed for the installation, service and maintenance. Due to constraints of using a conventional crane at some of the wind parks, Liftra has been developing a self-hoisting crane solution for gearbox and generator exchange, delivered in a 40’ container that can reach any place on the earth including remote countries or islands. During this presentation, we will show the “Elsterheide case”: the 10 Vestas V90 were erected above ancient lignite mines in 2005. The condition of the ground became so poor that no traditional crane could access the turbines any longer.
