Elevator with small driving sheave wrap angle

The invention discloses an elevator with a small driving sheave wrap angle. The elevator with the small driving sheave wrap angle comprises a car, a counterweight, a tractor, a driving sheave, at least one guide wheel and a hoist rope, wherein the driving sheave is configured on an output shaft of the tractor, the hoist rope winds the driving sheave and the guide wheels, and two ends of the hoist rope are connected with the car and the counterweight respectively. The elevator is characterized in that a wrap angle of the hoist rope on the driving sheave is controlled within 90-120 degrees, the ratio of the diameter of the driving sheave, the diameter of each guide wheel and the diameter of the hoist rope is smaller than 40. Compared with an existing elevator, the elevator has the advantages that output torque of the tractor is small; space of a machine room of the elevator can be effectively reduced, relative height of the tractor and the guide wheels is decreased; for the elevator without a machine room, by the wrap angle of a traction sheave and suspension ratio of the elevator, noise and vibration are reduced.
