Tower Crane Concept
What is a Tower Crane?
A compact self hoisting add-on crane
solution that makes it possible to lift
the main components during
installation and service on a WTG,
without the need of a conventional
mobile crane.
Why use a Tower Crane?
• Conventional mobile cranes are
expensive and in short supply
• Some components can be installed
with the tower crane. This reduces the
period of time in which a conventional
mobile crane is needed.
• …and eliminates the need for a
conventional mobile crane during
exchange of main components.
11 V112-3.0 MW – Product Management, February 1, 2010
Tower Crane Features
Advantages, Tower Crane versus conventional mobile crane
• Easier mobilization – fewer truck loads needed
• Quicker mobilization of crane
• Crane operated from nacelle or ground → operator always close to load
• Crane oscillation follows WTG → less sensitive to wind
Which components will the Tower Crane be able to lift(*)?
• Gearbox
• Gearbox high speed stage
• Main shaft and bearings
• Blades
• Generator
• Hub
• (*) list may differ from platform to platform
12 V112-3.0 MW – Product Management, February 1, 2010
Tower Crane Roadmap
• The Vestas Tower Crane will be applied as an internal tool by
Vestas Service.
Targeted platforms:
• V90-3.0 MW
• A tower crane is developed and being tested. It will be used for
change of major components, i.e. gearbox repairs.
• V82-1.65 MW, V90-3.0 MW, V112-3.0 MW and 2 MW platform
• A common cross-platform tower crane is under development.

Why is this a highly competitive turbine?
….That’s why!
36 V112-3.0 MW – Product Management, February 1, 2010
A large rotor diameter and a unique new blade

• maximizes output while causing the least possible
load to the turbine
• results in 55% larger swept area than the V90 rotor
• is less sensitive to dirt and salt, minimizing
production disturbances
The result: a steep power curve with high
production already at low and medium wind speeds
