Hydraulic Bolt Tensioner FAQ
What maintenance does a Hydraulic Bolt Tensioner require?
Regular maintenance should include checking hydraulic connections for leaks, inspecting the tensioner body for cracks or wear, and replacing seals every 12 months or 500 operations (whichever comes first). Always store the Hydraulic Bolt Tensioner in a clean, dry environment and protect it from impact damage.
How do I select the right Hydraulic Bolt Tensioner for my application?
Consider these factors: bolt size and grade, required preload force, available working space, and operating environment. Our HT-200 model suits smaller bolts (M12-M24), while the HT-2000 handles large flange connections (M64-M100). For extreme environments, we offer special models with enhanced corrosion protection.
Can I use one Hydraulic Bolt Tensioner for multiple bolt sizes?
Yes, but with limitations. Our universal adaptor kits allow a single Hydraulic Bolt Tensioner to accommodate different bolt sizes within its capacity range. However, we recommend dedicated tensioners for critical applications to ensure maximum accuracy and prevent cross-threading issues.
