Zusammenfassung:The utility model relates to an elevator, in particular to a traction-type elevator. The traction-type elevator with multiple gear ratios comprises a machine room, a car, a counter weight, a traction machine and a speed control system which is arranged in the machine room, wherein the traction machine is connected with the car through the speed control system and is a gearless traction machine; the speed control system adopts a pulley block system; and the gearless traction machine is connected with the car through the pulley block system. Due to the adoption of the technical scheme, the traction-type elevator adopts the pulley block system and the high-efficient and energy-saving gearless traction machine, thus effectively reducing vibration noise during use, improving the efficiency of the whole elevator and effectively saving energy.
