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;
