FIELD: life tests of various hydraulic cylinders. SUBSTANCE: stand includes bed frame with lever and hydraulic cylinder for change of lever inclination angle articulated on this bed frame. Hydraulic cylinder under test is articulated with lever and with tractive hydraulic cylinder through movable support mounted on lever. Tractive hydraulic cylinder is also connected with lever. Each hydraulic cylinder is placed is operation by means of independent pumping station controlled with the aid of logic unit by parameters of working process of hydraulic cylinder under test. EFFECT: enhanced reliability of estimation of service life of hydraulic cylinder under test. 6 dwg
