As a key load-bearing component of Stage Lighting hand chain hoist, the material used in the chain and its own strength performance are directly related to whether the equipment can operate reliably in the special working environment of the stage.
Performance Enhancement through Multi-Process Forging:
The manufacturing of chains for stage hand chain hoists is not a simple steel processing, but a combination of processes including forging → heat treatment (quenching + tempering) → precision forming to achieve a leap in performance:
- The forging process applies high pressure to the steel, refining the internal metal grains, densifying the structure, eliminating defects such as pores and cracks in the raw materials, and ensuring the uniform distribution of the chain's load-bearing capacity.
- Quenching (heating the chain to 800-900°C and then rapidly cooling it) enables the steel to form a hard martensite structure, significantly improving surface hardness and wear resistance.
- Tempering (low-temperature heating at 200-300°C) can eliminate the internal stress after quenching, preventing the chain from breaking due to excessive brittleness, while retaining sufficient toughness to ensure it is not easy to break under sudden impacts (such as accidental shaking of stage props).
After this set of processes, the comprehensive mechanical properties of the Stage Lighting hand chain hoistchain reach a balance - being both "hard and wear-resistant" and "flexible and impact-resistant", perfectly meeting the requirement of "both stability and toughness" in stage hoisting.
