What is the difference between geared and gearless elevators?

1. Geared traction elevators have fair installation and maintenance costs, and low energy consumption, and 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).
Gear-less traction elevators have a high initial cost, medium ongoing maintenance costs, and use energy a bit more efficiently than geared traction elevators.
2.Geared traction elevators are capable of travel speeds up to 500 feet per minute. The maximum travel distance for a geared traction elevator is around 250 feet.
Gear-less Traction Elevators have the wheel attached directly to the motor.  Gear-less traction elevators are capable of speeds up to 2,000 feet per minute and they have a maximum travel distance of around 2,000 feet so they are the only choice for high-rise applications.

Elevator gearless traction machine Advantages

— The floor to floor flight times are quicker and offers almost unlimited travel.
— Gearless traction car speeds are typically much faster than those of Geared traction applications. Geared traction cars can move at 500 fpm (2.5 m/s) or less and gearless traction cars move at speeds of 500 to 1,600 fpm (2.5 to 8.1 m/s).
— A wide range of capacities for both passenger and freight applications
— Because of the motor design, the gearless application deveHOP higher torque and runs at lower RPMs giving the gearless machine a long lifetime.

Elevator gearless traction machine Disadvantages

— The material cost and the installation time are substantially higher when compared to a geared traction elevator application.
— There are structural building considerations, since the loading forces are larger for the gearless application.
— Elevator maintenance cost is generally higher (compared to geared elevators).
