Dynamic forces and an actual load of a wire rope during its operation

Wire ropes are stressed by static and dynamic forces during their operation. The calculation of the wire ropes is based on their static stress.The dynamic forces are influenced by a higher value of safety. The intensity of the dynamic forces can be determined by a calculation, and by a practical measurement. The measurement was realized by the indicator of tension Talaten . The experimental work were caried out using the tensometric principle. The out-put of the obtained values is a graphical presentation with using a special software on PC. The dynamic forces and loads were measured on the hoisting wire rope. From measured data, the value of dynamic coeficient of rope was determined. The obtained measured values were compared with the results of empirical calculations.The knowledge of dynamic forces of ropes is of great importance for their safe operation, service life and economoc effect for users.
