Product Details
Ring Chain Structure: Core Guarantee for Load-Bearing Capacity and Stability The ring chain (commonly known as "circular link chain") of the Truss Lifting Stage Hand Hoist is a key component for force transmission. Its structural design directly affects the safety and stability of stage hoisting operations, with specific characteristics as follows: Precision Forging Process: The chain of the Truss Lifting Stage Hand Hoist is made of high-strength alloy steel (such as 20Mn2, 23MnCrNiMo, etc.) through cold heading, forging, and heat treatment (quenching + tempering). The fillet transitions of the links are precision-ground to avoid stress concentration. This process ensures the surface hardness of the links reaches HRC 40-45, with a tensile strength of ≥800MPa. It can not only bear static loads from heavy equipment such as stage trusses and lighting fixtures but also withstand dynamic impact forces generated during hoisting (e.g., inertial loads during sudden braking). Laminated Link Design: The links of the Truss Lifting Stage Hand Hoist adopt an "overlapping" meshing structure, where the inner and outer arc surfaces of adjacent links fit tightly, increasing the contact area by more than 30% compared to ordinary chains. This design not only reduces gaps during transmission and minimizes hoisting (measured to be ≤2° when unloaded and ≤1° when loaded) but also distributes local stress to prevent excessive wear at a single point, extending the chain's service life (capable of withstanding ≥10,000 cycles of hoisting under normal maintenance).
