The KATA – Pull-out instrument is used to perform extraction tests on metal components pre and post-inserted into concrete, with the aim of estimating the mechanical resistance of material. The KATA series Pull-out Extraction test instrument is classified as a “semi-destructive” test as, during test performance, a part of the element material being investigated is “torn” together with the dowel. The mechanical characteristics of concrete are therefore assessed measuring the force necessary for extraction of the previously inserted dowel. The test is performed connecting the test dowel to a hydraulic jack which, when pressurised, “extracts” it. The force measured by the pressure gauge is then analysed and compared with correlation curves to determine material resistance.
The Pull-Out test KIT is made with high quality, resistant materials to allow for use in difficult operating environments. The instrument is composed of: Manual use in difficult operating environments. The instrument is composed of: Manual 700Bar pressurisation unit, 0-400 Bar 0.1 Bar digital pressure gauge, 10Ton 50MM tear cylinder, 160MM – 220MM* contract ring, Pull Pin with ball joint, hard carring case
