Popis: The paper present theoretical studies and practical determinations in machines operating in dynamic mode fatigue. After expiry of the normalized lifetime of lifting equipment (overhead cranes, cranes, etc.). arises determination of residual functioning so that under normal safety to function at a normal operating capacity or diminished but not more than 15-20%. For exemplification is considered the investigation of a high gantry crane, MPT 20/5 – 20/4/4 m. In conclusion, after our determinations, the machine can operate with kinematics parameters set initially, but with reduced nominal load of 133 kN, i.e. approx. 13 t, and the lifetime of approx. 7.5 years.
