FIELD: strength tests. SUBSTANCE: unit has base made in form of two flat parallel plates 1 and 2. Four cases 3 are mounted between the plates along inversely perpendicular axes. Hydraulic cylinders 4 provided with rods 5 are mounted inside any case by means of collet conical bushings. Internal conical surface of the bushing is matched with external surface of hydraulic cylinder 4. Screws and nuts are intended for movement of hydraulic cylinders at axial direction. Hydraulic cylinders are fastened and space between them and collet conical bushings 6 is adjusted by means of nuts. Hydraulic cylinders are connected to hydraulic pressure source in pairs through control units. Rods 5 of hydraulic cylinders are connected with gripping devices 16 inside which the tested specimen is mounted or member of construction. EFFECT: improved reliability; improved efficiency. 4 dwg
