Up-tower cranes offer solutions to the problems created by traditional cranes. These alternative solutions will reduce mobilization costs, avoid delays due to high wind speeds and road permits, minimize ground pressures, and decrease the overall footprint as compared to using traditional cranes on the ground.
This crane series for up-tower WTG maintenance has been specifically designed to work as temporary up-tower crane for major component repair in a wind turbine nacelle and are placed on top of a wind turbine.
The up-tower cranes provide the following benefits:
