Applications
Applications Utilizing Compact Design and High Pre-Load:
Wind turbine blade bearing bolts: Tightening large-diameter bolts on wind turbine blades requires significant pre-load for optimal performance and safety. Multistage tensioners provide the necessary force in a compact design, ideal for accessing confined spaces within the nacelle.
Heavy machinery assembly: In construction equipment, mining vehicles, and other heavy machinery, high-pre-load connections are crucial for structural integrity and component reliability. Multistage tensioners deliver the required force within tight working areas.
Pipelines and pressure vessels: Flange connections in high-pressure pipelines and vessels sometimes require pre-load beyond the capacity of single-stage tensioners. Multistage models provide the necessary force without excessive tool size or cumbersome equipment.
Nuclear power plants: Maintaining secure bolted connections in critical components within nuclear power plants demands precise pre-load and compact tools for access. Multistage tensioners cater to these needs with their high-force capabilities and maneuverability.
Advantages of Multistage Tensioners:
Greater pre-load capacity: They can achieve significantly higher pre-load compared to single-stage tensioners, making them suitable for demanding applications.
Compact design: Their unique multi-stage configuration provides high force within a smaller footprint, ideal for confined spaces or limited access areas.
Controlled application: They offer precise control over pre-load, ensuring accurate and consistent tensioning even on large-diameter bolts.
Versatility: They can be used with various bolt sizes and configurations, making them suitable for diverse applications.
Improved safety: The controlled and accurate pre-load application minimizes the risk of bolt over-tightening and potential failures.
Considerations for Multistage Tensioners:
Complexity: Compared to single-stage models, they may require more specialized training and maintenance due to their intricate mechanisms.
Cost: Their higher pre-load capabilities and advanced features generally lead to a higher price point compared to simpler tensioners.
Space requirements: While more compact than some single-stage models, they may still require additional space for setup and operation compared to manual tools.
