The fewer the number of idler wheels, the longer the life of the elevator tow rope will be, and at the same time, there will be less noise from the collision of the idler and the tow. The placement of the counterweight along the axis of the idlers will also be effective. The shorter the axis of the idlers, the better the quality of the elevator movement. This placement will also be effective in the angle of the idler axis. The smaller the angle of the idler axis relative to the axis of the elevator car rail, the better the quality of the elevator will be. Another factor that will affect the quality of the elevator is the balance of the elevator car or the precise placement of the cabin rails. When designing, attention should be paid to the balance of the cabin. The more the axis of the rails is in the center of gravity of the cabin, the more favorable the movement will be. Therefore, in some cases, in high-speed elevators, balance weights are used for the cabin to balance the elevator car.Some points about elevator design were mentioned, by observing which the quality of the elevator will be more desirable. The second factor that is very important in the quality of the elevator is the installation of the elevator. When laying rails, it is very important to be careful in adjusting the head ties of the elevator rails. In order for the head ties to be adjusted correctly, the brackets must first be installed and aligned vertically, and then the rails must be laid. If the brackets and rails are installed at the same time, the welding and its tension will cause errors in the rail laying, which will cause shocks in the path of movement. In addition, in this type of rail laying, the brackets cannot be aligned vertically, and this will cause the ties to be either inward or outward.Welding should not be used in the installation of any of the elevator items because welding stress causes errors in the installation of the elevator, and bolts and nuts should be used in the installation of the doors so that the doors can be adjusted more accurately

Using high-quality parts such as motors, control panels, doors, and rails can greatly affect the quality and lifespan of the elevator. The coordination of the motor with the panel drive is very effective in smooth and vibration-free movement. Elevator doors, which play the most role in elevator failure, are of great importance in elevator failure, so you must be careful in choosing doors. Fortunately, in our beloved Iran, quality doors are produced and available Simataksun products  An example of high-quality elevator doors

The suitability of the rails with the speed of the elevator is very important, so when purchasing rails, a rail that is suitable for the speed of the elevator cabin should be used. Using poor quality rails will cause vibration and shock during movement, so it should be kept in mind that purchasing a quality elevator will require proper initial design, precise implementation, and the use of quality parts. The first and second factors will cause optimal movement, and the third factor will be effective in both movement and the life of the elevator
