This video shows construction at a mountain wind farm: segmented hoisting and jointing of precast concrete wind turbine towers. Tower segments are prefabricated in sections at the factory, transported to the site, and hoisted and assembled one by one like building blocks. The crane lowers each segment slowly while workers position themselves on top of the segment to align, straighten, connect and secure it. Applied Technical Principles and Construction Equipment The hoisting and jointing of concrete tower sections is based on the core principles of concentric axis alignment and tight flange contact. Main equipment includes mobile cranes, total stations, hydraulic torque wrenches and high-strength bolt assemblies for tower connection. Construction Process The segmented hoisting and jointing of concrete wind turbine towers consists of these core stages: - Preparation Stage: Re-survey the tower base flange, verify base flatness and the position of embedded anchor bolts to meet hoisting specifications. - Lifting and Transfer Stage: The crane lifts a single tower segment steadily and moves it above the foundation. - Alignment and Centering Stage: Lower the segment gradually. Workers on top adjust orientation, match flange bolt holes and ensure the tower stays vertical and concentric. - Tightening and Locking Stage: Once aligned, fasten the high-strength bolts in sequence to ensure tight contact between the two flanges. - Inspection and Completion Stage: Check verticality and bolt preload, make fine adjustments, and finish jointing for this segment. Core Functions and Advantages - Suitable for mountainous terrain: Segmented precast towers are easy to transport on mountain roads and adapt to complex site conditions at mountain wind farms. - Durable structure: Concrete resists weathering and fatigue, enduring strong winds and temperature changes in mountain areas over the long term. - Fast assembly: Factory prefabrication plus on-site splicing eliminates cast-in-place work and shortens the construction schedule. Key Construction Points - Axis centering: Strictly control tower verticality and flange gaps to meet precision requirements for wind turbine installation. - Controlled bolting: High-strength bolt preload must comply with standards to prevent loosening during operation. - Working-at-height control: The tower top is a high-risk working zone; fall protection must be implemented to prevent falls. Safety Precautions Safety control takes priority for all operations. Check wind speed before hoisting; suspend lifting work in high winds. Workers aloft must wear safety harnesses and hard hats at all times. Mark off a hoisting exclusion zone and keep unauthorized personnel out.
