May 2, 2019 – Enerpac, a specialist in heavy lifting technology and high-pressure hydraulics, announced the HM-Series HydraMax and updated GT-Series Hydraulic Topside Tensioners for bolt tightening. Both product series are engineered to achieve accurate bolt-load in single or multiple tensioner configurations, delivering bolt tensioning with performance on critical joints.
The HM-Series HydraMax tensioners are designed to generate high-bolt loads associated with compact flanges, overcoming dimensional restraints with 15 load cells for bolts from ¾-in. to 4-in. and M20 to M100 – covering all standard sizes with multiple load cell options. The HM-Series is designed to fit all standard flanges, including ANSI, API and compact flanges based on Norsok L005.
The HydraMax tool can be used in almost every industry and in a number of different applications. HydraMax HM-Series features include:
- Quick release bridge offering faster turnaround for different applications
- Long-stroke capability of 15mm (9/16-in.) reducing actuations and over-stroke conditions
- Twin ports for connection of multiple tools
- Mechanical over-stroke prevention or over-stroke relief valve with spring return
- Piston stroke indicator
- Anti-slip grip for handling
- Captive socket to eliminate falling object risk
In addition to launching the HydraMax Bolt Tensioners, Enerpac is also updating its GT-Series Topside Bolt Tensioners. The GT range offers a captive socket system that prevents the socket from falling or being separated from the tool. A GT7 (M100-M105) tensioner has been added, expanding the series to seven GT load cells and bridges to accommodate bolts from ‚Öù-in. to 4-in. and M16 to M105.
Additional GT-Series features include:
- 7 load cell & bridges
- Detachable and rotational bridge
- Full bridge window
- Piston stroke indicator for operator awareness to prevent tool over-stroke
- Anti-slip grip for handling
- Twin ports for linking multiple tools to provide even tensioning
