FIELD: transport.
SUBSTANCE: invention relates to elevator unit components. Component of elevator pulley (24) comprises at least one set of cable (22) and said pulley. In compliance with proposed versions, said pulley features preset shape and size for interaction with at least one cable in said elevator system. Wear coefficient of coating (27) applied on said pulley makes less than 2.0×10-10 mm2/N. In compliance with second version, coating material is selected from the group consisting of cobalt alloys containing chromium, molybdenum, cobalt-phosphorus and nickel-tungsten alloys.
EFFECT: higher wear resistance.
