Applications

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.

Features

• Fast Spring Piston Retract: Save time between tensioning cycles.
• Geared Nut Run-Down: Achieve rapid initial thread engagement.
• Spring-Located Sockets: Simplify setup and reduce operator fatigue.
• Easy Handling and Positioning: Maneuver the tensioner effortlessly in cramped spaces.
• Hose and Connection Protection: Minimize safety risks and potential damage.
