Hydraulic Safety Interlock Guard Tensioner

A Riverhawk-exclusive patented safety system for tensioning flange connections on GE turbines — engineered for single-user operation with full containment of all components.

Hydraulic Safety Interlock Guard Tensioner

Product Overview

The Hydraulic Safety Interlock Tensioner is a Riverhawk exclusive product designed with patented developments. It is a safety system made for tensioning flange connections on GE turbines. The HSIG guard clamps securely to the flange to absorb the energy and fully contain the tool in the event of a failure.

The hydraulic interlock prevents the tool from being used if the guard is not correctly and firmly attached to the flange. No other hydraulic bolt tensioner in the world provides the protection and peace of mind that the HSIG provides.

Designed with safety and performance in mind, the Hydraulic Safety Interlock Guard is a modular tensioner that is engineered for single-user operation and provides full containment of all components during the tensioning process.
