Steel wire ropes and traction/deflection sheaves are generally considered a "commodity ". This is in away correct, considering that steel ropes have been produced for over 175 years, but from another point of view there are several aspects that need to be carefully considered. In the beginning of the lift industry, great care was devoted to the checking of specific pressure between ropes and sheaves [5], and also to the linearity of the reeving arrangement. Not only was this, but also the number of start per hour and rope speed were taken into consideration to assess the maximum value of the specific pressure. It seems that in the recent years such requirement has been withdrawn as it is perceived as "old fashioned", and the new harmonized standard removed completely any explicit reference to the Specific Pressure calculation. With the result that today very hard working condition are in service for both ropes and sheaves and consequently shorter life time have to be expected from them. The aim of this paper is simply to analyze the working condition between ropes and sheaves and pointing out the importance of some issues like specific pressure, deflection angles, sheaves rotated by 90°, etc.
