New Topside Hydraulic Bolt Tensioners

Our new HM-Series HydraMax Topside Hydraulic Bolt Tensioners are designed to overcome the dimensional constraints and bolt load requirements of compact flanges. HydraMax Tensioners fit all standard flanges, including ANSI, API and Norsok L005 compact flanges. The tensioner’s compact size and high bolt load capacity allow a maximum number of bolt diameters to be covered with a minimum number of tools.

The HydraMax Bolt Tensioners are field proven tools. HydraMax Tensioners have been the most recognizable tensioner in Hydratight’s bolting portfolio for more than a decade. In January, 2019 we began merging two leading bolting companies; Enerpac and Hydratight into a single company. The HydraMax Tensioners are among many of the Hydratight tools which will be added to Enerpac’s product line.

GT-Series Bolt Tensioner Update

In addition to launching the new HydraMax Bolt Tensioners, we will also be updating our GT-Series Topside Bolt Tensioners. A new GT7 tensioner will be added to our GT tensioner range. The seven GT load cells and bridges will now cover bolts from 5/8" to 4” & M16 to M105. The GT range will benefit from a captive socket system that will prevent the socket falling or being lost from the tool.

Features - HydraMax HM-Series

  • Fifteen load cells cover bolts from ¾” to 4” & M20 to M100 – covering all standard sizes with multiple load cell options
  • Quick release bridge – faster turnaround for different applications
  • Long stroke capability of 9/16" (15mm) – reduces number of actuations
  • Twin ports – enables user to link multiple tools
  • Stroke indicator – for operator awareness to deter tool over stroke
  • Anti-slip grip – for more secure handling
  • Captive socket – eliminates falling object risk
  • HM06-HM15 equipped with spring return – faster retraction reducing cycle times

Features - GT-Series
