Guide rail/In-car equipment

The guide rail is what allows for the safe and precise movement of the car and counterweight.
This rail offers a path for the elevator to ascend and descend. The component which comes into contact with the guide rail and the car is called the guide shoe. The guide shoe reduces friction through the application of lubricant. Roller guides, which have more friction-reducing functionality, are used for high-speed elevators.
