KoalaLifter climbs the same way a Koala does, it embraces the tower of the wind turbine just like this little animal embraces and climbs the trees. KoalaLifter is able to perform major correctives such as components exchanges (blade and components of the nacelle) and the turbine erection. These variants for maintenance and erection can also be transferred to the offshore market using a wave compensation platform.
KoalaLifter adapts to any type of tower of any height.
Operates with high winds, it is easy to install with an easy dumping system, and it is transported without any special permits. These features give the opportunity to countries where new wind farm projects are feasible.
Blades up to 20 tons, Nacelle components up to 30 tons and turbine erection up to 150 tons.
Component exchange takes 5-6 hours. Turbine erection takes 17 hours. The wind turbine shutdown is shorter than with current methods.
Less tree cutting & civil works because there is no need to create a clearance area to move KoalaLifter. It is transported only in a regular 40’ truck, where current methods need and use up to 40 trucks.
The component always travels with the KoalaLifter equipment. Exchanging the components or erecting the turbine is much safer than using cables.
Controlled by a 300m scope remote control. Only 1 technician is needed on ground level away from the equipment. Safety is guaranteed.
One of the most important advantages of KoalaLifter is the high adaptability of the collars. They are able to copy the shape and diameter of the wind turbine tower thanks to their adaptable friction collars. KoalaLifter is able to climb up the tower using the strength of the tower with winds up to 25m/second reducing the wind turbine downtime. This provides reliability, robustness and safety during the operation.
The climbing process starts tightening the expandable collars of the first section, then the second section, with its expandable collars open, expands towards the nacelle. When this second section reaches its end stroke, its expandable collars gets tightened. At this point, the collars of the first section are opened and the first section gets pulled by the second section. This process is repeated until the equipment reaches the tower tip in order to reach the component that needs to be exchanged.
The whole equipment fits and it is transported in a 40’ standard skeleton trailer. This concept makes it easy to carry KoalaLifter around the world to countries where heavy cranes are not available or very expensive.
It is controlled by a radio frequency remote control. All the work regarding the staff/workers is done on ground level.
