Up's and down's of lifts

 

Ashika Agrahari

Are you afraid of going into a lift? If yes, then read this article to know many things about the lifts, and I hope that you start going into the lifts after reading this.

The lift, also called as the elevator works just like a well with the pulley system which helps us to draw water from the well. When you see a well, you firstly see a rope that is tied up with a bucket and passes through a wheel which has a hole in the centre and gets a stick passed through it (as in the picture). Then it can be very easy to draw water from the well by just pulling the rope.

Similarly, elevators also work like the well’s pulley system. The only difference is that the pulley of a well uses our muscular energy whereas an elevator uses sophisticated mechanisms for handling the weight of people in the elevator.

The elevator has a metal box (where we stand) that is connected to a strong and tough metal rope. This rope passes through a sheave (plays the same role of wheel in a well). The sheave is operated by an electrical motor. There is a machine room in the shaft where the motor and other parts of the elevator are kept. The shaft is the path where the elevator moves. There is a drive unit which is responsible for the movement and speed of the lift. So, if the elevator stops suddenly or has a slow start, it is because the drive unit is not working properly. In the machine room there is a control unit or a control panel. When we press any button, the signal first goes to the control unit and then the control unit gets it translated through the system and tells the motor whether to move up or down. Once the elevator reaches its destination, there's a signal sent to the control room to stop and let the passengers exit. Guide rails are generally made of steel, and they have a T shape. They are put vertically in the shaft to direct and guide the course of the elevator counterweight and elevator car. Even if the rope is snapped, the elevator would not fall as elevators have passive, automatic, built-in braking system

There are 3 main types of elevators which are commonly used, those are:

1. Traction elevators with machine room
2. Machine room less (MRL) Traction elevators 
3. Hydraulic elevators

Hydraulic elevators are functioned by piston and fluid. This kind of elevator does not use a pully system as the wells have. 

Traction Elevators with machine room is also used in Ganga Vertica. And DO YOU KNOW? That there are 14 lifts in our GV. Traction Elevators with machine room is also used in Ganga Vertica.

I hope that you know a lot about the elevators.
