• wherein the core of each hoisting rope is coated with a substantially thin sheath that forms a surface of the hoisting rope,
• wherein the sheath is softer than the core,
• wherein a diameter of the core of each hoisting rope is a diameter of the hoisting rope excluding only the sheath,
• wherein the diameter of the core is greater than or equal to 2.5 mm and less than or equal to 8 mm,
• wherein each of the plurality of rope grooves is of a substantially semi-circular cross-sectional form, and
• wherein each of the plurality of rope grooves is coated.
