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.


  • 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.

duo tensioners offer a range of options and features, including special threads, special load requirements, twin or single port configurations, protective handle, special bridge for tight clearances, swivel connections, cycle counter, gear drive nut run-down, spring piston return, misalignment compensation, and ARMOURMAX anti-corrosion, anti-wear coating.

- Multi-stage hydraulic bolt tensioners are designed for applications requiring sequential tensioning, allowing controlled tightening of bolts in multiple stages.

- Hydraulic tensioners operate by using hydraulic pressure to extend a piston, applying tension to the bolt. Multi-stage tensioners allow for sequential tensioning, improving control and accuracy.

The load loss factor in bolt tensioning refers to the reduction in tension force over time due to various factors, such as material relaxation, joint settling, and external loads. It quantifies the loss of preload in a bolted joint, impacting the joint's overall integrity.

Bolt tensioning is essential for achieving and maintaining the required clamping force in bolted joints. Proper tensioning ensures joint integrity, preventing issues like leakage, gasket damage, and joint failure. It enhances safety, reliability, and the overall performance of the assembly.
