1.0 INTRODUCTION
Overview
The aim of the HydraMax® Bolt Tensioning
System is to quickly and accurately apply a
pre-determined load to a nut and bolt assembly.
It has been primarily developed for use where
safety, speed, ease of operation and reliability
are paramount.
The Enerpac HydraMax® Bolt Tensioner has
been designed for the controlled and accurate
application of a pre-determined load to a nut
and bolt assembly.
In use, HydraMax® Bolt Tensioners are
attached to the stud bolts of a joint assembly; in
either a uniform or alternating arrangement, as
required by the application to be tensioned. The
HydraMax® Bolt Tensioner can also be used for
a single stud bolt application.
HydraMax® Bolt Tensioners are to be used as
part of a complete hydraulic system, alongside
an electric pump and hose arrangement.
The series can be used on a wide range of bolt
size and pressure requirements.
