Bolt Tensioner

Bolt tensioners are essential tools used in industrial applications for applying accurate and consistent tension to bolts. The SL-TA Self-resetting bolt tensioner and SL-GT Hydraulic bolt tensioner are two specific types within this category. The SL-TA Self-resetting bolt tensioner is designed to automatically reset after each use, making it efficient and convenient for repetitive tensioning tasks. On the other hand, the SL-GT Hydraulic bolt tensioner utilizes hydraulic pressure to apply precise tension, ideal for applications where accuracy is paramount. Both types offer reliable and efficient solutions for achieving proper bolt tension in various industrial settings.

SL-HT Wind Turbine Tensioners

Hydraulic tensioning is the ideal method for tightening bolted connections. Hydraulic tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical connections. At SOLY, we’ve been building hydraulic tensioners and nuts since 2007.

The SL-HT tensioners are a purpose designed range of tools to suit all applications in wind turbine manufacturing and operations. These tensioners offer a reliable and consistent method of simultaneously tensioning multiple joints and have an integrated fail safe design to enhance workplace safety.

Designed for special needs such as small space, large load, long life and fast speed, meeting ENISO898:1999 standards;
