WHERE OUR PROVEN BOLTING SOLUTIONS SET THE STANDARD IN CRITICAL APPLICATIONS

TorcUP offers a specialized range of industrial bolting solutions and bolt tensioning technology specifically engineered for the unique challenges of wind turbine assembly and maintenance.

KEY MACHINERY AND APPLICATION POINTS

Critical Bolting Applications

Bolting solutions are applied across the entire structure of a wind turbine, from the ground up:

Foundation and Tower: Includes foundation bolts, tower bolts, and the critical tower-to-nacelle connections.
Nacelle and Powertrain: Key points involve generator couplings, gearbox bearings, and main bearings.
Rotors and Control: Essential for blade bearings, blade-to-hub bolts, hub-to-nacelle connections, and yaw bearings.
Installation Support: The TX-4 hydraulic wrench, equipped with a 2 3/4" ratchet link, is utilized for lifting trunnions on GE-9E and 7E turbine bases, applying 1200 lbf-ft of torque.

Preferred Tooling and Technology

The wind industry utilizes a mix of hydraulic, battery, and tensioning tools to meet strict technical specifications:

Bolt Tensioning Technology: Designed for the demanding requirements of wind turbines, these tensioners are available in single, multi-stage, and foundation configurations. They feature a 1500 bar rating, automatic piston retraction, and a safe failure design.
Hydraulic Series (TU/SQ/TX/TXU): These tools provide a wide torque range from 45-58,000 lbf-ft with +/- 3% repeatable accuracy. They are recognized for having only three moving parts, which reduces the cost of ownership.
Battery-Powered Series (VT/Volta): Preferred for their freedom and flexibility in the field, these tools handle torques from 120-3000 lbf-ft and are ISO 17025 certified.
