Pesaje de palas de aerogeneradores

Solución gravimétrica para garantizar la calidad de las palas de aerogeneradores

ANYLOAD aplicó la tecnología de tensado líder del sector para desarrollar un sistema crítico que garantiza la uniformidad en la fabricación de palas de aerogeneradores.

Las palas de los aerogeneradores deben estar equilibradas con precisión en peso y centro de gravedad para minimizar los desequilibrios de peso que pueden acortar considerablemente la vida útil prevista de los aerogeneradores. Unas palas desequilibradas pueden ejercer fuerzas desiguales sobre el buje del rotor, lo que provoca desalineaciones y fallos por fatiga de materiales en la caja de engranajes y otros componentes de la turbina.

Desafío

  1. Extreme Blade Weight: Modern wind turbine blades can weigh more than 50 tonnes, requiring a weighing system capable of handling extremely high loads without compromising measurement accuracy.
  2. Critical Balance Accuracy: Even a small weight imbalance of only a few hundred kilograms can generate excessive vibration during operation, accelerating wear on turbine gearboxes, bearings, and other drivetrain components.
  3. Large Structural Dimensions: Wind turbine blades can exceed 100 meters in length, making them difficult to support and weigh accurately using conventional weighing methods while maintaining stable load distribution.
  4. Long-Term Measurement Reliability: Blade manufacturers require weighing equipment that maintains consistent accuracy throughout continuous production while allowing periodic calibration to minimize downtime and ensure long-term measurement performance.

Solución

  1. High-Capacity Wireless Tension Link: ANYLOAD developed a custom wireless tension link specifically designed for heavy wind turbine blade weighing, providing safe and reliable force measurement for loads exceeding 50 tonnes.
  2. Exceptional Measurement Accuracy: The tension link is factory calibrated to achieve a measurement accuracy of ±5 kg at a 50-tonne load, allowing manufacturers to identify and correct even small weight imbalances before blade installation.
  3. Custom Mounting Assembly: A purpose-built mounting assembly with a certified high safety factor ensures secure load transfer while providing stable and repeatable measurements for large blade structures during lifting and weighing operations.
  4. Preventative Maintenance Program: Scheduled recalibration and refurbishment services maintain long-term measurement accuracy, maximize equipment uptime, and ensure consistent weighing performance throughout the production lifecycle.

Conclusión

ANYLOAD’s wireless tension link solution enables manufacturers to accurately weigh and balance wind turbine blades before installation. By detecting even minor weight variations with exceptional precision, manufacturers can reduce drivetrain vibration, extend the service life of critical turbine components, improve operational reliability, and maintain consistent product quality across every blade produced.

Custom load pin load cells integrated into port crane container lifting systems ensure accurate load monitoring and enhance safety during container handling. This integrated solution is applicable to many overhead crane, container, and logistics, and maritime shipping operations.

Liberación rápida Ganchos de amarre

Quick release mooring hooks (QRHs) play a critical role in safely securing vessels at ports, oil terminals, LNG facilities, and commercial harbors. By integrating custom load pin load cells directly into the hook assembly, operators can continuously monitor mooring line tension, prevent dangerous overload conditions, and ensure vessels can be released safely during emergency situations without compromising operational reliability.

Células de carga S-Beam for Race Car Applications

In race car development, accurate force measurement is critical for vehicle setup, performance evaluation, and durability testing. Applications such as brake and clutch pedal force measurement, suspension link monitoring, steering force analysis, and aerodynamic load measurement require sensors that deliver fast, stable, and repeatable data under highly dynamic conditions. ANYLOAD’s S-beam load cells are designed for these motorsport environments, offering high dynamic response, precise force measurement, and robust environmental protection for both track and test use.
