What is the balance weight of the elevator?

Maybe you have heard the name of elevator weight, but you don't know what this weight is and what it is used for. As the name suggests, this weight is for balancing the weight of the elevator. This device consists of a certain number of weights and a metal frame. There are different types of elevator balance weights such as: metal weights, concrete weights, cast iron weights, lead weights, plastic weights, and galvanized weights. To learn more about its types, stay with us in the rest of the article.

As it was said at the beginning of the article, the elevator balance weight helps the elevator to maintain its balance. This device is composed of a number of weights and a metal frame that is connected to the elevator cabin by a pulley and a steel rope. It should be noted that the weights inside the metal frame are placed in such a way that they are not thrown out in case of falling or stopping suddenly. The main task of the balance weight is to neutralize the weight of the passengers. Static weight of parts, weight of equipment, etc. is In fact, this weight balances the weight of the elevator by neutralizing their weight. In addition, the balance weight creates a tension between the towing wire and the elevator plates, which provides the frictional force necessary to move the towing wires.

This weight, when the elevator moves towards It moves down, it goes up, and when the elevator moves up, it goes down. This event, together with neutralizing the force inside the cabin, creates balance in the elevator. Remember that all elevators must have this weight so that the weight of the elevator is balanced and its vibration is reduced. However, if your elevator vibrates a lot during movement, this weight is definitely not installed correctly and in accordance with its standard tips.

By balancing the elevator box, this weight makes it easier for the elevator motor to raise and lower this box.
This weight puts less force on the cables, which causes to increase the security of the elevator.
In addition to the ease of operation of the elevator motor, this weight also significantly reduces the energy of this motor.
In addition to the mentioned items, the balance weight causes the elevator to move quickly.
This The weight also reduces the amount and amount of energy required by the elevator. Finally, the balance weight makes the elevator easier to control than before.

You may ask how to calculate the balance weight for each elevator after fully familiarizing yourself with this piece. Calculating the number and mass of the weight must be done by experts and skilled people. Because, these people use a special formula to calculate the balance weight of each elevator. In fact, experts calculate the mass and number of weights of each elevator, considering the capacity and weight of the elevator cabin, according to a special formula. do The formula for calculating the balance weight of the elevator is as follows:

The mass of the balance weights = the mass of the cable travel + the mass of the empty cabin and its equipment + 50% of the nominal capacity of the cabin

It should be mentioned that Know that the location of balance weights depends on various factors such as: conditions of the elevator system, elevator shaft, well engineering, etc. It depends. In fact, according to the stated factors, it is possible that the weights behind the cabin, the vicinity of the cabin, etc. be placed.

Expert people must have done calculations related to load bearing before starting the operation of weight placement.
Experienced people must equalize the weight of the elevator cabin with the balance weight of the elevator. Otherwise, if the weight of the cabin is not the same as the balance weight, the elevator standard certificate will not be issued.
Experts must carefully calculate and prepare the required amount and dimensions of the balance weight of each elevator.
