When in operation for example in aerial ropeways, cranes or mines the ropes run over rollers and are deflected by sheaves. On the one hand the rope is subjected to tensile and bending loads and to torsion, and on the other hand additional stresses occur due to the helix-shaped structure of the rope. Running ropes of ropeway plants, cranes and mines have a finite service life. For this reason safe operation is only possible when the ropes are tested regularly and damage which necessitates the replacement of the rope is recognised reliably and in time before a hazardous operating state is reached. The authors describe the development of a visual inspection tool which simultaneously images a length of rope from fours sides. The data may be stored and reviewed at a later time to allow a thorough inspection and record of the external condition of the rope. (8 refs.)
