Product Details
As the Theatrical Hand Chain Hoist , the material selection and strength performance of the chain directly determine the reliability of the equipment under special stage working conditions.
Precision Selection of High-Strength Alloy Steel: The material of the chain for Theatrical Hand Chain Hoist is not ordinary steel, but strictly selected low-alloy high-strength structural steels such as 20Mn2 and 30CrMo. The advantages of such steels are as follows: - 20Mn2 steel has a relatively high manganese content. After forging and heat treatment, its tensile strength can reach 800-1000MPa, and it has good hardenability, which can ensure that the chain is not easy to deform when bearing heavy objects. - 30CrMo steel, due to the addition of chromium and molybdenum elements, not only has higher tensile strength (up to 900MPa or more), but also has excellent high-temperature strength and impact toughness. Even in the environment where the local temperature rises due to long-term irradiation of stage lights, it can still maintain stable load-bearing performance. The material selection of Theatrical Hand Chain Hoist fundamentally meets the complex requirements of "high frequency, heavy load, and multi-environment" in stage hoisting.
