These traction elevators have the wheel directly attached to the electric motor. Gearless traction elevators have a very high travel speed i.e. up to 2000 ft. per minute and can travel a great distance.
Guide rails are part of the inner workings of most elevator and lift shafts, functioning as the vertical, internal track. The guide rails are fixed to two sides of the shaft; one guides the elevator car and the other for the counterweight.
The guide shoe is a slidable nylon block between the elevator guide rail and the car. It is called guide shoe. It can fix the car on the guide rail so that the car can only move up and down.
Elevator emergency automatic rescue device (also known as ARD) is a special device installed in an elevator which is only used during an event of a power failure or blackout in a building.
Elevators also have electromagnetic brakes that engage when the car comes to a stop. The electromagnets actually keep the brakes in the open position, instead of closing them. With this design, the brakes will automatically clamp shut if the elevator loses power
