Machine Room Elevators

These traction elevators have a gear box which is attached to the electric motor and turns the hoist sheave and moves the rope. Geared traction elevators are driven by either Direct Current (DC) or Alternating Current (AC) and their maximum speed is up to 500ft per minute. This speed is lower than gearless traction elevators but higher than many other types of elevators. Moreover, these elevators are capable of travelling to a maximum distance of 250ft. Geared traction elevators have fair installation and maintenance costs, and low energy consumption. While their speed is slower than gearless elevators, geared elevators offer advantages in terms of energy efficiency as they use less power to turn the pulley(sheave). Furthermore these elevators have have the ability to lift loads up to 13,600kg.
