What is the balance weight of the elevator?

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, the static weight of the parts, the weight of the 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 necessary frictional force for the movement of the towing wire. This weight goes up when the elevator moves down and goes down when the elevator moves up. 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.

If this weight is installed correctly and in compliance with the standard tips, it has countless advantages, some of which include the following: By balancing the elevator box, this weight makes it easier for the elevator motor to raise and lower the box. This weight exerts less force on the cables, which increases the safety of the elevator. In addition to the ease of operation of the elevator motor, this weight also significantly reduces the amount of energy of this motor. In addition to the mentioned cases, the balance weight causes the elevator to move quickly. This 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.

Now that you are fully familiar with this weight and its benefits, you may ask if there are different types of this weight? Yes, this weight has different types based on gender, weight and dimensions, some of which include the following:

One of the oldest types of balance weights is the concrete type, which has two models that include the following: Concrete weight with plastic coating Concrete weight with galvanized sheet coating Concrete balance weights have different types in terms of dimensions, such as: 57, 67, 77, 87, 97, 107. Each of these dimensions are used according to the type of weight frame.

The second type of balance weight is the lead type, whose density is much higher than other weights. This weight, like the concrete weight, has different dimensions and people can order it in different dimensions based on their needs.

The third type of balance weight is the cast iron weight, which is much more expensive than the concrete weight. This weight is very suitable when people need a thin weight with a heavy weight for a space with a small well. This weight, like the others, has different dimensions that are produced according to people's needs

In the past few years, people often used plastic weights to balance elevators because they were cheap. But, over time, due to various reasons such as: new standards, people no longer use this weight. Today, galvanized weights are often used instead of plastic weights. This weight is first placed in a steel frame and then fixed and screwed with the help of a machine. At the end, a galvanized cover is drawn on this frame. Galvanized weights also have many dimensions that are produced according to the needs of each person.
