Bolt Tensioners

Bravis Bolt Tensioners, available in single-stage (TC) and multi-stage (TTC) configurations, are specifically designed to meet the demands of high-performance applications. Made from lightweight aircraft-grade aluminum alloy and special high-strength steel, these tensioners are built for long-lasting durability. The slim, versatile design makes them ideal for use in confined spaces, providing the optimal solution for hydraulic bolt tensioning.

• Optical Overstroke Indicator: Allows for precise monitoring of stroke, ensuring accurate tensioning during operation.
• Hydraulic Unit Rotation: The hydraulic unit can be rotated around 360°, offering flexibility and ease of use in various positions.
• Spring-Assisted Coupling: This feature prevents damage by allowing a spring-assisted connection between the rotating sleeve and hexagonal nut.
• Removable Handle and Carrying Strap: Designed for maximum comfort and safety, these features make transportation and handling easier.
• Parallel-Connected Tensioners: The tensioners are suitable for use with parallel-connected tools, ensuring flexibility in large-scale operations.
• Anti-Rotation Mechanism: Feather key ensures no rotational movement between the tension nut and bolt, guaranteeing precise torque application.

This advanced set of features makes the Bravis Bolt Tensioners highly reliable and efficient in both confined and expansive work environments, ensuring optimal performance in critical applications  such as Wind Turbines foundation bolts, Necelle Joints, Hub and Blade Joints.

We welcome OEM ODM inquiries for bulk order and specially made to order customized Tensioners as per your drawing.
