As one of the important parts of the crane, the counterweight block is mainly used to maintain the balance of the crane. The material of the counterweight block of the crane is preferably made of high specific gravity tungsten alloy as the raw material. Although the production cost and price of tungsten alloy weight is higher than that of lead and iron, it has stronger practicability, longer life, relatively long service life, low replacement frequency and reduced cost. Its advantages mainly include the following three:
One is due to the good compactness of tungsten alloy weights. The density of the counterweight is high, which can effectively reduce the volume of the counterweight, reduce the volume, and improve the space utilization rate of the mechanical equipment.
The second is that the material of the tungsten alloy counterweight has good chemical stability and corrosion resistance, which means that the counterweight can have a long service life even if it works in the open air for a long time, and does not need to be replaced frequently. Wear-resistant, durable and corrosion-resistant.
Third, the high specific gravity tungsten alloy is environmentally friendly and pollution-free, and will not cause serious pollution to the natural environment.
