Elevator and elevator rope

An elevator without a machine room, the elevator comprising:

• a hoisting machine;
• a set of hoisting ropes;
• a traction sheave that comprises a plurality of grooves;
• a counterweight;
• an elevator car;
• counterweight guide rails;
• and
• elevator car guide rails;
• wherein the hoisting machine engages the set of hoisting ropes via the traction sheave,
• wherein each of the hoisting ropes has a substantially circular cross-section,
• wherein each respective hoisting rope of the hoisting ropes comprises steel wires of circular, non-circular, or circular and non-circular cross-section, twisted together to form strands,
• wherein the strands of each respective hoisting rope are twisted together to form the respective hoisting rope,
• wherein a thickness of each of the hoisting ropes is greater than or equal to 2.5 mm and less than or equal to 8 mm,
• wherein each of the hoisting ropes individually contacts one of the plurality of grooves,
• wherein the hoisting ropes support the counterweight moving on the counterweight guide rails and the elevator car moving on the elevator car guide rails,
• wherein a cross-sectional area of the steel wires of the hoisting ropes is greater than 0.015 mm2 and less than 0.2 mm2,
• wherein the strength of the steel wires of the hoisting ropes is greater than 2300 N/mm2 and less than 2700 N/mm2, and
• wherein a speed governor rope is thicker in diameter than the hoisting ropes.
