Stresser P7

The Elematic Stresser P7 is a single stressing machine for pre-stressing strands during the production of prestressed precast concrete products such as hollow core slabs.

Stresser P7-16

Prestressing force 160 kN
Stroke 500 mm
Strand size 9.2-12.7 mm
Weight appr. 350 kg


The Stresser P7-16 consists of a wagon with a hydraulic unit, a hydraulic jack suspended from a balancer on a pole and a remote control. The hydraulic unit is fitted with a manometer to measure the stressing force.

For products with long strands, several pulling cycles maybe needed. The unit must be calibrated before starting production.


Like all Elematic machinery, safety features are built in. The Stresser P7 features a pressure regulating valve to limit the pre-stressing force and to make the process safer. It meets the EC Machine Directive requirements and comes with thorough, clear operator, maintenance and safety manuals in the required language.
