The diameter of the rope and traction sheaves is determined, among other things, by the German TAS mining standard, which covers technical requirements for shaft and inclined haulage systems. This requires the ratio of the sheave diameter to the rope diameter to be greater than or equal to 80, so TKF has chosen a sheave diameter of 4,320 mm for
