Gearless Traction Elevators are built specially to be the most efficient option for high-rise buildings. This elevator has its wheel attached onto the electric motor to directly rotate the drive sheave. This results in a swift ride with speeds that reach up to 2,000 feet per minute and can reach travel heights up to nearly 2,000 feet.
The best way to distinguish a gearless traction elevator from a geared traction elevator is where the wheel is attached. The geared traction elevator will have its wheel attached to the AC or DC motor.

Some benefits of the gearless traction elevator include:
- Low energy consumption
- High electric motor durability
- High reliability
Functionally, the gearless traction elevator is designed to carry a full passenger load and accelerate to its highest speed without disturbing any passengers with a jerky stop. The minimum time that this elevator needs to slow to a stop is 4.5 to 5.0 seconds. This engineering ensures passengers a smooth ride and quick travel to their destination floor.
