- Single acting design with spring assisted return
- High grade alloy steel construction
- Nitrocarburised piston
- Maximum piston stroke indicator
Product Overview
The SBT imperial range of hydraulic bolt tensioners is designed primarily for topside operations and features spring assisted return hydraulic piston which reduces bolt tensioning cycle times considerably. Once the hydraulic pressure is released, the tensioner piston automatically starts to retract, thus removing the need to manually wind down the threaded puller. The range currently comprises of 22 models, suitable for standard size bolts from 1¼” to 4” diameter.
- Capacities from 457 to 2649 kN
