Special Edition Turbine Tower

Product catalog summary

Introduction
The document discusses a successful pilot project by Max Bögl Group in Bischberg, Germany, focusing on innovative wind energy systems using revolving tower cranes for the construction of hybrid wind turbine towers.

Innovative Construction Approach
Max Bögl has introduced a novel method for constructing wind turbine towers using revolving tower cranes. These cranes, developed in collaboration with Liebherr, are designed to extend with the tower sections and can reach a maximum hook height of over 150 meters with a single guy wire connection. This approach allows for effective operation even at high wind speeds of up to 20 meters per second.

Advantages of Revolving Tower Cranes
The revolving tower cranes offer significant advantages, particularly in forest locations, by reducing the required site area to approximately 1,200 square meters. Unlike crawler cranes, which need extensive space for boom construction and removal, revolving tower cranes minimize environmental impact and logistical challenges. They can be transported using standard heavy goods vehicles, unlike crawler cranes that require numerous heavy loads.

Successful Implementation
The pilot project in Bischberg demonstrated the effectiveness of the revolving tower cranes. The cranes successfully hoisted a 70-tonne gondola to a hub height of 140 meters and precisely positioned rotor blades with a diameter of 112 meters. This achievement highlights the technical innovation and efficiency of the Max Bögl Group's approach.

Conclusion
The use of self-climbing revolving tower cranes in wind turbine construction represents a significant advancement in the field, offering flexibility, efficiency, and economic benefits. This innovative assembly technology is particularly beneficial in challenging environments, showcasing Max Bögl's commitment to sustainable and efficient construction practices.
