The Safe Load of Winding Ropes in Large Koepe Hoists - An Assessment Based on Nondestructive Testing

The ropes of Koepe hoists in mines are subjected to static and dynamic stresses. Further stresses result from the structural geometry of the rope drive and from the climatic conditions in the shaft. These stresses on the ropes cause wire breaks, corrosion, wear and slackening which reduce the load capacity of the ropes in the course of their service life. These various forms of damage occur either individually or in combination.
