HM15LC, HydraMax Hydraulic Topside Bolt Tensioners, M90 - M100 Maximum Thread Range

Enerpac HM15LC is a robust load cell from the HydraMax series of hydraulic topside bolt tensioners, engineered for high-load tensioning of large-diameter bolts (M90–M100) in topside applications on standard flanges such as ANSI, API, and Norsok L005 compact flanges. Offering 30% greater load capacity than traditional tensioners, this model features a long 15 mm stroke for fewer cycles, over-stroke protection via relief valve, and a quick-release bridge for efficient setup, ensuring precise, uniform bolt loading at up to 1500 bar with enhanced safety through a captive socket and anti-slip grip, ideal for oil & gas, power, and heavy industrial maintenance.
