Professional manufacturer of one-stop supporting products for industrial and mining accessories.
The three-ring chain for mining accessories is an important component used to connect transportation vehicles on narrow-gauge railways on the surface and underground in mines.
Material and Process
Material: Generally, there are two types of materials: forged and welded. The forged three-ring chain is made of high-quality steel, formed through multiple forgings, such as 20 manganese vanadium, 25 manganese vanadium, 40CrMo, etc., which have high strength and good toughness.
Process: The whole forged mining three-ring chain is made from a single piece of material through nine forgings, including processes like upsetting, drawing, flattening, and initial shaping. Compared to welded chains, the continuous performance of the fiber structure of the whole forged mining three-ring chain is better, and its impact, tensile, and bending properties are all higher than standard requirements.
Specifications and Models
Common specifications include φ32×50×165, φ32×60×140, 22150, 26118, 28120, 30120, 30130, 34147, 38*145, etc.
Function and Advantages
Function: Mainly used to connect mining cars with each other, allowing multiple mining cars to form a train, facilitating the transportation of coal, gangue, materials, etc., on the tracks.
Advantages: Using a three-ring chain to connect mining cars can reduce the likelihood of damage to steel wire ropes, increasing the safety and reliability of the transportation process. The three-ring chain undergoes strict production processes and quality inspections to ensure it can withstand large tensile and impact forces, adapting to the complex and harsh working environment of mines.
