Product Details

The chain of the theatre hand hoist plays a crucial role in stage lifting operations. Its performance directly affects the safe operation and service life of the equipment, and the characteristics of rust and corrosion resistance as well as smoothness and wear resistance are core advantages achieved through elaborate design and technological processing.

The smooth and wear-resistant characteristics of the theatre hand chain hoist chain have also undergone careful refinement. After surface treatment, the surface roughness of the chain can be controlled below Ra0.8μm, and the contact area between chain links increases by more than 15%. When the chain meshes and drives with the sprocket, the friction coefficient is reduced to below 0.12, which effectively reduces the mechanical wear between them. This smooth characteristic can also reduce the probability of dust and oil adhesion. For daily cleaning, it only needs to be gently wiped with a soft cloth dipped in a special cleaning agent, which greatly simplifies the maintenance process. At the same time, the smooth surface is more conducive to the uniform distribution of lubricating oil, forming a stable oil film, which further reduces friction loss. This enables the theatre hand hoist chain to maintain flexible operation during long-term and high-frequency use, avoiding lifting obstacles caused by jamming or sticking, and ensuring the stable and efficient lifting process of stage equipment. Whether it is quickly adjusting the position of lighting or accurately hoisting audio equipment, this smoothness and wear resistance can provide a solid guarantee for the stable operation of stage machinery.
