China Suppliers Factory - Crane Manganese Steel Chain G80 for Industrial Lifting Applications
Working Principle
The working principle of the lifting chain is to drive the chain to rotate through an electric motor, causing the hook to move up and down. Specifically, the hook is connected to the motor through a chain. When the motor starts running, the chain begins to rotate, and the hook rises or falls accordingly, thereby achieving the lifting or lowering of goods.
⚙️Components and functions of lifting chains
A lifting chain is usually composed of an electric motor, a chain, and a hook. The electric motor provides power, the chain is responsible for transmitting power, and the hook is used for hanging and lifting goods. These components work together to ensure that the lifting chain can efficiently and safely complete the lifting operation.
Scope of Use
The main uses of lifting chains include lifting heavy objects, towing, and bundling. As an accessory for electric hoists, chain hoists, group hoists, etc., lifting chains are commonly used to lift heavy objects. In addition, lifting chains can also be used for traction and bundling, with specific application scenarios as follows:
🏗️Purpose of lifting: The lifting chain plays a crucial role in cranes and is an essential lifting device. By adjusting the length of the chain, it is possible to adapt to lifting requirements at different heights, thereby improving work efficiency and expanding the scope of work.
🔗Traction purpose: The lifting chain can be used to pull heavy objects, especially when moving or dragging heavy objects, the lifting chain can provide sufficient tension and stability.
📦Binding purpose: In some cases, lifting chains can also be used to bind heavy objects, ensuring their stability and safety during transportation or storage.
In addition, the grade and material of the lifting chain have a significant impact on its performance. For example, lifting chains of grades 80 and 100 are refined through complex processes such as polishing, blackening, dipping, electroplating, and spraying and have high strength and corrosion resistance, making them suitable for various working environments.

Frequently Asked Questions
Q What is the working principle of a lifting chain?
A lifting chain operates by using an electric motor to drive the chain in a rotational motion. The hook, connected to the motor via the chain, rises or lowers as the chain rotates, enabling the efficient lifting and lowering of goods.
Q What materials are used to manufacture crane chains?
Our crane chains are manufactured using G80 manganese steel raw material (20Mh2). The material undergoes multiple heat treatments including high temperature quenching and tempering, resulting in high strength, excellent toughness, and superior corrosion resistance.
Q What are the main applications of lifting chains?
Lifting chains are widely used for lifting heavy objects, traction, and binding purposes. They are commonly applied in metallurgical and construction industries, port terminals, factory operations, and construction projects. They serve as essential accessories for electric hoists, chain hoists, and group hoists.
Q What grades of lifting chains are available, and what are the differences?
Lifting chains are available in grades such as Grade 80 and Grade 100. These grades differ in strength and load-bearing capacity. Higher-grade chains undergo more complex processes including polishing, blackening, dipping, electroplating, and spraying, offering greater strength and enhanced corrosion resistance for demanding working environments.
Q Can lifting chains be customized to specific requirements?
Yes. We offer abundant inventory with diverse specifications and widely used standard materials. Custom matching is fully supported to meet specific customer requirements in terms of size, length, grade, and surface treatment.
Q What surface treatment is applied to the crane chain?
The crane chain undergoes a rolling light surface treatment process. The welding joints are smooth, and the chain goes through quenching treatment to ensure a stable structure, smooth surface, and long service life across various working environments.
