A tower crane taller than 241 m installs wind turbines

Theo Interesting EngineeringZoomlion’s LW3600-240NB giant tower crane is specifically designed for the next generation of ultra-tall wind turbines. According to the company, the machine can lift up to 240 tons and reach heights of over 241 meters, allowing for the installation of some of the largest onshore wind turbines. The crane’s lifting capacity is equivalent to lifting 200 small cars to the top of an 80-story building.

The wind power industry continuously increases the size of turbines to capture more energy and improve the economic efficiency of the project. Current onshore turbines often have shaft heights above 150 m, and some new generation turbine models are approaching the 200 m mark.

Theo CPGlarger turbines produce more electricity but also pose many challenges. The process of transporting and assembling rotor blades, turbine engine nacelles and tower body sections weighing hundreds of tons requires increasingly specialized lifting equipment. Traditional crawler cranes can do this job but require a large assembly area and long setup times.

According to Zoomlion, LW3600-240NB targets the high-capacity wind power market with super-tall towers. One of the main advantages of the device is the relatively small installation area, requiring only an operating area of ​​35 x 55 meters, and the soil bearing capacity (the ability of the soil to bear the maximum load without failure or excessive settlement) of 0.18 MPa, which reduces the need for site preparation. This crane can support the installation of wind turbines with capacities greater than 10 megawatts and shaft heights over 200 m, a segment that is expected to expand in the future.

At altitudes above 200 m, strong winds can put great pressure on both the crane structure and the part being lifted. To ensure stable operation, Zoomlion’s tower cranes use a low load ratio design and high-strength clamping rings to enhance wind resistance and sturdiness. The system can withstand winds level 10 on the Beaufort scale (equivalent to 89-102 km/h). Some other equipment includes dual cylinder synchronous lifting technology that improves safety and an intelligent digital control system that monitors operations throughout the life of the crane.

In addition to wind farms, Zoomlion shares that the LW3600-240NB crane can be used in large-scale infrastructure projects, including bridge construction, power generation facilities, chemical plants and industrial buildings.

In the context of the current global energy crisis and shortage, wind power is becoming one of the leading strategic solutions that countries are focusing on strongly developing. According to the Global Wind Energy Council, installed wind power capacity will reach a record 165 gigawatts (GW) in 2025, up 40% over the previous year. Current wind power technology trends focus on Optimize scale and performance with The birth of generations of super-large turbines with capacities from 15 MW to more than 20 MW, with rotor diameters of about 200-250 m to maximize power output per tower.
