What is KoalaLifter?
KoalaLifter is the most efficient and flexible wind craneless system in the industry. This disruptive self-climbing solution harnesses the strength of the wind turbine tower to support its ascent, embracing the tower with expandable collars, much like a koala clinging to a tree. Suitable for any wind turbine model of any height, KoalaLifter revolutionizes the maintenance landscape. It performs major correctives or even full turbine erections without the need for high tonnage cranes. Its design not only boosts reliability and robustness but also cuts turbine downtime significantly… truly a smart alternative in today’s innovative wind energy market.
Main Benefits
KoalaLifter provides a host of remarkable benefits that transform wind turbine maintenance and erection into a safer and more efficient process. Key figures and facts include:
- 100% Universal: Adaptable to any wind turbine model.
- 25m/s Operation Limit: Efficient functioning even in high winds.
- 70% Less Turbine Downtime: Enables major corrective actions and turbine erections faster than any other method.
- 0% Workforce Risk: Operated remotely to ensure safety.
- 80% Less Contaminating: Requires only one conventional truck instead of a massive convoy.
Innovative Product Line
KoalaLifter offers a diverse range of products designed to meet various operational needs. The KL-N35 is engineered as a nacelle components exchanger capable of handling up to 35 tons of weight, while the KL-N80 increases this capacity up to 80 tons. The KL-Gorilla provides an erecting system complete with a self-rotating crane, and the KL-Offshore is tailored for offshore major correctives or even the construction of wind turbines. With loading capacities that can handle blades up to 20 tons, nacelle components up to 30 tons, and turbine erections up to 150 tons, the product lineup reinforces versatility and high performance… all built to adapt seamlessly to various challenges.
Cutting-Edge Operation and Safety
The operational process of KoalaLifter is both ingenious and safe. It climbs the turbine tower by using adaptable friction collars that mimic the tower’s shape and diameter. The process begins with tightening the expandable collars of the first section. Then, the second section—initially with its collars open—expands toward the nacelle. Once the second section reaches its end stroke, its collars tighten, prompting the first section’s collars to open so that it can be pulled upward. This recursive motion continues until the equipment reaches the tower’s tip. Controlled via a radio frequency remote control with a 300-meter scope, the system ensures that only one technician is needed on ground level, enhancing overall safety and minimizing workforce exposure… making each operation both secure and precise.
Transportability and Global Reach
KoalaLifter stands out for its remarkable transportability and ease of movement around the globe. The entire equipment fits into a standard 40’ skeleton trailer, allowing conventional trucks to handle transportation without the need for special permits. This means that even in regions where heavy cranes are not available or are prohibitively expensive, KoalaLifter can make a significant impact. Additionally, the minimized need for civil works—eliminating extensive tree cutting or creating clearance areas—further underscores its efficiency. The system’s global reach is enhanced by its lightweight design and simplicity, ensuring it can be moved to remote, onshore, and offshore sites with minimal logistical challenges… delivering performance wherever it is needed.
