At least one rope pulley may include a solid surface including a plurality of rope grooves configured to receive at least one hoisting rope. Each rope groove may generally conform to a semi-circular shape and may include a groove bottom and sides. The at least one rope pulley may include a coating adhesively bonded to it. The coating may directly contact the at least one hoisting rope. A coating thickness may be less than or equal to about 3 mm. At the groove bottom of each rope groove, the coating thickness may be substantially less than half a thickness of the at least one hoisting rope. The coating may cover the groove bottom and sides of each rope groove.
