UP-TOWER SERVICE CRANES

The design and manufacturing of our up-tower cranes, started as an alternative solution to the problems created by traditional cranes for O&M work on onshore wind turbines. The design is based on operational experiences and in close cooperation with our sister company and worldwide O&M service contractor LiftWerx. This new crane technology for WTG maintenance has been specifically designed to work as a temporary up-tower crane for major component repair in a wind turbine nacelle and are mounted on top of a wind turbine.

This alternative solution substantially reduces service risks, costs and time.

Since its introduction in early 2019, this new crane technology has been proven very successful. Based on our extensive offshore experience for decades, we have also developed this new technology for offshore fixed and floating wind turbines.

The complete range of our up-tower cranes are designed as Zero-Emission-Crane™, fully powered by the wind turbine back feed power circuit, and powered and controlled from a single shared control/power unit, saving time (number of lifts) and space up-tower.

The up-tower cranes provide many benefits:

• Safer operations
• Small carbon footprint
• Operations in high wind speeds (12 m/s average & 18 m/s gusts)
• No crop damages  (onshore)
• Low (de)mobilization costs
• No crane hardstand required (0nshore)
• Less costly onshore project delays:
  -> No road permits (2-3 trucks)
  -> No civil works
• Small footprint at tower base (onshore)
• Eliminating large mobile or crawler cranes or large offshore a/o jack-up vessels
