Euro Press Pack CMF#NJ Cylinder – Spring Return


The Euro Press Pack CMF#NJ is a spring return cylinder designed for use in verifying and testing studs in barriers and guard rails. It is necessary to verify the strength of the studs through traction tests during the installation and the usage in order to verify the integrity of the material and its adherence to the concrete. To this purpose the Euro Press Pack CMF#NJ system is specialised to fulfill simple and efficient tensile strength tests.

The system comes provided with a quick female coupler combined with a hydraulic pump and an instrument to measure the force applied on the stud while testing. If calibrated as a measurement instrument it can be used also for calibration certificated tests. Depending on the application, the set can be equipped with ancillaries for  traction of M16, M20 and M24 studs. The cylinder is activated by a PNP130[G] or PN131[G] hand pump and a flexible hose SN20M with a male coupler. The hole on the hollow ram cylinder allows the appropriate tie-rod to  screw it on the stud. Extending the piston of the cylinder, a tensile force, proportional to the pressure generated by the pump, is exerted on the stud. Pressure gauge accurately measures the pressure exerted upon the studs for accurate control and results when testing.
