At large-scale equipment hoisting sites, the scene of the main crane lifting heavy components with strong power is remarkable, and the chain hoist, as an auxiliary tool, is actually a key force in ensuring operational safety. It has become the "golden partner" of the main crane due to its lightweight, portable, and precise control advantages, playing an important role in equipment adjustment and safety protection.

The posture calibration before lifting the equipment is the primary task of the chain hoist. Large components such as generator sets and pressure vessels often have difficulty maintaining horizontal alignment due to center of gravity offset. At this point, the operator will hang hand pulled hoists on both sides of the component, adjust the height of the component to the optimal lifting angle by alternately pulling the chain, and avoid shaking caused by uneven force during the lifting of the main crane. This precise control ability is difficult to replace by large machinery.

During the lifting process of the main crane, the chain hoist plays the role of a "stabilizer". When components move in the air, wind or inertia may cause them to sway. Operators can control the posture of components in real-time by tightening or loosening the chain of the chain hoist, preventing collisions with surrounding equipment. Especially when working in narrow spaces, the chain hoist can help the main crane achieve "millimeter level" positioning, ensuring precise alignment and installation of components.

When using a chain hoist, it is necessary to strictly follow the load limit and regularly check the wear of the chain and hook. It is the combination of rigorous operation and tool advantages that makes the chain hoist an important support for ensuring safety and efficiency in large-scale lifting, silently guarding the smooth completion of every operation.
