Crane Selection for Wind Farm Turbine & Tower Lifting
In short: Kelude Heavy Industry delivers lifting solutions for wind farms across four key applications—turbine installation, tower erection, blade maintenance, and foundation work—with lifting capacities from 80 to 1,600 t for the main crane and 25 to 80 t for auxiliary cranes. The cost per turbine installation ranges from approximately $45,000 to $178,000. Main cranes are crawler cranes (650–1,600 t) or all-terrain cranes (500–1,200 t), while auxiliary cranes handle tower and nacelle delivery in tandem with the main unit. Blade installation uses a dedicated blade lifting beam, covering onshore turbines from 2 to 8 MW and offshore units from 8 to 16 MW—spanning the full process from foundation work to grid connection.
Wind Farm Crane Selection Guide
Turbine Installation | Tower Erection | Blade Maintenance | Foundation Work
Wind farm construction—from foundation work to tower erection and turbine installation—requires coordinated use of multiple lifting assets, including main cranes, auxiliary cranes, blade-specific spreaders, and truck-mounted cranes. Kelude Heavy Industry combines its own crane rental fleet with in-house manufacturing of wind-specific lifting tools to deliver end-to-end lifting solutions, from site preparation through long-term maintenance.

Wind Turbine Installation: The Core Challenge of Ultra-Large Tonnage Work at Height
Wind turbine installation is the most demanding lifting phase in any wind farm construction project. A single nacelle can weigh between 100 and 300 metric tons, with installation heights ranging from 80 to 120 m, all while working on rugged, uneven terrain. Large crawler cranes (500–800 t class) or all-terrain truck cranes (400–800 t class) are the industry standard for this work, equipped with superlift counterweights and torque limiting systems to ensure safe operation at height. Kelude has completed more than 50 wind power hoisting projects and can recommend the optimal main crane model based on turbine specifications and site terrain.
Tower Section Hoisting with Main and Auxiliary Crane Coordination
Tower sections are erected using the "push-up method," where the main crane lifts the upper end of the tower section while an auxiliary crane guides the bottom to prevent ground contact. Each section is slowly raised from horizontal by the main crane, with the auxiliary crane feeding it forward until the flange face is vertical. Kelude's specially designed tower lifting beams feature angle adjustment to accommodate flanges of varying diameters, while soft lifting slings protect the flange surface coating throughout the process.
Blade Maintenance and Foundation Construction Lifting Equipment
Blades are the long-term maintenance focus of any wind farm. With blade lengths now reaching 40–90 m, replacement or repair requires dedicated blade handling cranes working in tandem with high-altitude platforms. Kelude's hydraulic blade fixtures are custom-contoured to match specific blade airfoils and are equipped with load sensors that provide real-time gripping force data. For foundation work, mid-size truck cranes in the 25–80 t range handle rebar cage rotation and platen assembly, while truck-mounted cranes provide rapid transport of anchor bolts and embedded parts.
Kelude: Crane Service Advantages for Wind Farms
Kelude has specialized in wind power hoisting for many years and holds a Class 1 certification for power engineering lifting operations. With a fleet of 650–1,600 t crawler cranes and 500–1,200 t all-terrain cranes, we have completed more than 500 onshore and 100 offshore wind turbine installations across China's major wind power bases.
FAQ
Q: Why can't a standard crane be used for wind turbine installation?
A: Wind turbine installation heights range from 80 to 120 m, with Lifting Capacity requirements of 100 t to 300 t. A standard crane's Rated Lifting Capacity drops sharply as jib length increases, and only large wind-power-specific cranes can maintain sufficient lifting capability at these heights. Kelude recommends wind-power main booms with jib lengths of 80–120 m, where the superlift counterweight can increase the rated load by 20%–30%.
Q: Why is a main crane plus a tailing crane required for tower erection?
A: Tower sections must be lifted from a horizontal to a vertical position. The main crane hoists the top flange of the tower section while the tailing crane supports the bottom flange and guides it into place. The main crane bears the majority of the tower weight throughout the process, while the tailing crane keeps the tower base from contacting the ground or nearby equipment. Kelude's tailing-in method ensures uniform load distribution during the upending process, preventing localized bending.
Q: What specialized Lifting equipment is needed for blade replacement?
A: Blade replacement requires a dedicated blade-handling crane or a large truck crane fitted with blade Fixtures. Kelude's hydraulic blade Fixture adapts to changes in blade airfoil profile, using hydraulic luffing control to manage blade Angle and a rotating lifting beam to flip the blade from horizontal to 90°. The key challenge is transporting blades along narrow wind farm access roads, which requires specialized blade lifting and transport vehicles.
Q: What Lifting equipment is required during foundation construction?
A: Foundation work primarily requires truck cranes (25 t–80 t) for rebar cage lifting and flipping, platen assembly, and Anchor bolt installation, while Truck-mounted cranes handle rapid transfer of materials and equipment. Kelude offers integrated construction lifting rental services for wind farm foundations, with crane types and quantities flexibly allocated according to the construction schedule to reduce overall Lifting equipment costs.
