Some Problems of Uneven Load Distribution in Wire Rope of Multirope Friction Drives

Some selected problems concerning unequal load distribution in wire ropes used with the multi-rope drives have been presented in the paper. By means of a simplified analysis of stresses in wire ropes a considerable effect of axial loads on the lifetime of wire ropes has been shown. Some methods used in practice have been described for determining the loads in wire ropes. From some exemplifying load distributions the most frequent reasons of an unequal load distribution has been given.
