The one or more rope pulleys may be provided with one or more rope grooves. Each rope groove may have a groove bottom and groove sides. At least one rope pulley may have a coating adhesively bonded to it. At the groove bottom, a thickness of the coating may be at most about 3 mm. At the groove bottom, the thickness of the coating may be substantially less than half a thickness of the at least one hoisting rope running in the one or more rope grooves. At the groove sides, the thickness of the coating may be at most about 3 mm. The coating may be thicker at the groove bottom than at the groove sides.
