Compared with traditional steel and iron weights, high-density tungsten alloy has greater density and better corrosion resistance. This means that using tungsten alloy as a counterweight can achieve the goal of small size and large weight while increasing the service life of the counterweight. More generally speaking, tungsten alloy can maintain the balance, stability and reliability of the crane, thereby improving the safety of the project.
In order to ensure the safety and reliability of the crane during operation, modern cranes are equipped with a variety of safety devices. These devices can protect parts or alert operators in unexpected situations.
Among them, each relief valve in the hydraulic system can prevent the hydraulic system pressure from being too high and avoid equipment damage; the boom amplitude safety device can prevent the boom from being overturned due to excessive boom amplitude; the boom telescopic safety device can control the telescopic speed of the boom. , to avoid accidents caused by too fast expansion and contraction; the height limit device can limit the height of the hook to prevent the hook from being too high and causing collision with surrounding objects; the leg locking device can ensure the stability and safety of the leg during operation The lifting weight indicator can display the weight of the hook in real time to avoid overload operation; the lifting characteristics table can provide information such as the weight and size of different materials for easy reference by operators.
In the past, cranes often used cement blocks or iron blocks as counterweights. However, due to their poor corrosion resistance and small specific gravity, these traditional counterweights are gradually being phased out and replaced by high-specific gravity tungsten alloys. According to industry insiders, high specific gravity tungsten alloys have higher strength and corrosion resistance, as well as greater density and longer service life. These advantages make tungsten alloy the most suitable crane counterweight material to replace cement blocks.
