Standard Hydraulic tensioner

We develop hydraulic tensioners for you to perform precise and uniform tightenings or assemblies. A wide range of standard or special tensioners, applicable for mechanical assembly, equipment under pressure or civil engineering, is at your disposal.
Owing to its small dimensions (due to the use of a 1500 bar high pressure), the standard range allows you to perform types of the bolt tightenings. For any specific application, we propose an engineering appropriate to you needs.

Submarine (underwater) tensioners

Next to our range of standard hydraulic tensioners we have developed a tensioner for Off-shore applications
This Submarine range combines the advantages of thermal properties of an hydraulic tensioner and an easy use in difficult conditions (visibility, environment, …)
For all specific applications we offer a study appropriate for your needs.

Compact tensioner

With the aim of developing very heavy tightening strains in the smallest size possible, we offer this range of compact tensioners.
Because the puller and the hydraulic part are made in one piece, the simple and quick use of these tensioners is ideal for special applications.

Hydraulic nut

The hydraulic nut allows the assembly tightening with a high precision and in the shortest time.
It replaces the conventional nut and has a mechanical mecanism to maintain the load after the hydraulic stressing up.

For all specific applications we offer a study appropriate for your needs.

Hydraulic tensioner for civil works

The DUPERRIER INDUSTRIE company has developed for civil engineering, most particularly for prestressing anchor bars, formwork and provisional installations (incremantal lunch), a wide range of hydraulic tensioners to install and remove bolted joints.
The public works range offers a large span of tightness, applying double effect tensioners of small dimensions (due to the use of a 1200 bar high pressure) with a 50 mm long travel, for a quick and easy use as a result of their light weight.
For any specific application, we propose an engineering appropriate to you needs.
