Single-Stage

Single-stage tensioners are versatile and reliable hydraulic bolt tensioners suitable for high load and tight space applications with limited overhead clearance.

Single-Stage

Optimized for use on wind turbines they have been designed for long-life, low-maintenance use, and are suitable for use on single bolts, or grouped together for multiple tightening of bolted joints. Single tensioners are extensively used for slewing rings, power-gen applications, structural and all critical bolting. Single-Stage Hydraulic Tensioners are designed for speed. Fast spring piston retract, geared nut run-down and spring located sockets, improve process time on each tensioning operation. High cycle life, over-stroke protection and the latest seal technology ensure low maintenance operation to keep projects on schedule.
