Hoisting chains are a type of chain specifically designed for lifting operations. They are mainly used for hoisting and moving heavy objects and are one of the core components of lifting machinery (such as cranes, hoists, etc.).

Main Characteristics

- Material: Mostly made of high-strength alloy steel (such as 20Mn2, 35CrMo, etc.), which has high hardness and toughness after heat treatment and can withstand huge tensile forces.

- Structure: Composed of multiple links connected by welding or riveting, commonly in forms like single-loop chains and double-loop chains. Some are equipped with accessories such as connecting hooks and lifting rings.

Application Scenarios

Widely used in industries, construction, logistics and other fields, for example:

- Hoisting large equipment and molds in factory workshops;

- Lifting steel materials and prefabricated components on construction sites;

- Handling containers and heavy goods in ports and docks, etc.

When in use, safety regulations must be strictly followed to avoid overloading and rough operation, so as to ensure operational safety.

Advantages of Hoisting Chains

- Strong load-bearing capacity: Made of high-strength alloy materials, they can withstand extremely large tensile forces and heavy loads, suitable for heavy lifting operations such as hoisting large equipment and steel materials.

- High safety: With a robust structure, they have a low risk of breaking. Some models are equipped with safety catches and other devices to prevent accidental slipping of heavy objects, ensuring operational safety.

- Good adaptability: They can work stably in harsh environments such as high temperature, humidity, and dust, especially suitable for complex scenarios like outdoor areas or industrial workshops.

- Precise transmission: Through the meshing transmission of chain links, the lifting process runs smoothly. Unlike ropes or belts, they do not slip, ensuring accurate lifting and lowering positions of heavy objects.

- Convenient maintenance: Daily maintenance mainly involves regular lubrication, inspection of chain link wear and connection status. Worn parts are relatively easy to replace, with low costs.

Key Points for Using Hoisting Chains

- Proper selection: Choose hoisting chains of appropriate specifications (such as chain link size and strength grade) according to the lifting weight and operating environment, and avoid overloading.

- Regular inspection: Before use, check if chain links are deformed, cracked, or excessively worn, and if connections are firm. Stop use and repair immediately if problems are found.

- Correct operation: Ensure the chain is under vertical force during lifting, avoid slanting, pulling, or twisting to prevent uneven stress on chain links that may cause breakage. No one is allowed under the heavy object.

- Maintenance: Clean the chain regularly and apply special lubricants to prevent rust and excessive wear. Keep it dry during long-term storage and avoid contact with corrosive substances.

- Compliance with regulations: Use strictly in accordance with operating procedures, and do not use it for operations beyond its design scope, such as dragging or impact lifting.
