The Vestas Tower Crane


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.


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


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.

V112 - 3.0 MW Offshore IEC S

Product Presentation


V112 – 3.0 MW Offshore IEC S

• Superior Cost of Energy Performance

• Designed for Reliability and Endurance

• Superior Serviceability

Why is this a highly competitive turbine?

….That’s why!

design

• 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

Highly Competitive Annual Energy Production
