A counterweight is a weight used to increase its own weight to maintain balance. Counterweight iron is a process in which the metal is melted into a liquid that meets certain requirements and poured into the mold, and the castings with predetermined shape, size and properties are obtained after cooling, solidification and cleaning.Counterweight iron is one of the basic processes in modern mechanical manufacturing industry. Counterweight iron is an early metal hot working process, which has a history of about 6000 years.

Counterweight plays a role in maintaining balance. Its weight is added according to the strength of the car itself. If it is too heavy, it may cause the strength damage of the car when hoisting. Some large tonnage crane counterweights are removable. When hoisting small tonnage, you can hang less or no counterweight. However, when hoisting large tonnage, we must hang all counterweights, and even add extra lifting devices.
When one side of the crane cantilever or one side of the weight, it needs to be counterweight on the other side, the weight commonly used are cement and iron.
Depending on the balance of each hub, so the counterweight is also different to ensure that the hub is balanced and unshakable when it rolls.
