Advantages of H78A chain：

The H78A Cast Link Chain is a high-strength industrial cast link and transfer chain designed for heavy-duty conveying, drag, and material handling applications. Its cast sidebars and heat-treated steel pins deliver superior durability, excellent wear resistance, and long service life under continuous operation.

This chain is widely used in forestry, lumber conveyor systems, steel mills, mining, and other demanding industrial environments where conventional roller chain wear rapidly fails.

Heavy Duty Design – Built for drag, transfer, and conveyor applications with concentrated loads
Cast Malleable Iron Sidebars – High resistance to wear and impact damage
Heat Treated Steel Pins – Improves strength and fatigue performance
Stable Performance in Harsh Environments – Suitable for abrasive, dusty, and high-load conditions
Interchangeable with Standard “H” Class Chain – Can replace similar chains without changing sprockets in many cases
Versatile Usage – Works well in forestry, hefty material handling, and production conveyors

Brand Reputation: JINQIU CHAIN, as a prominent chains manufacturer, we offer a complete range of lumber conveyor chains. They combine high strength,durability and fatigue resistance to suit demanding applications.

Quality & Performance: This chain transmission industrial chain boasts an impressive high tensile strength, ensuring it can withstand heavy loads and demanding applications in manufacturing plants and construction works.

Price & Value: We offer customization services to meet the specific needs of our clients. This includes OEM and ODM support, allowing us to tailor the product to their requirements. Whether it's a trial order or a large quantity, we can accommodate various customization requests.

Supply Chain: The chain is suitable for various applications, including sugar mill, and can be used in different industries, making it an ideal choice for businesses with diverse needs, as requested by the customer.

● Mining Industry

Cast pintle chain are widely used in the mining industry, especially in the conveying and processing of ore. The ore is usually very heavy and rough, and the use of cast hinge chains can provide strong load-bearing capacity to help transport the ore from the mine to the processing station or transportation point.

● Cement Industry

In the cement production process, cast pintle chains are used to transport various raw materials such as limestone, clay, coal, etc. As these materials are often heavy and coarse-grained, Cast Pintle Chain can provide sufficient strength and wear resistance to ensure smooth material transportation, even in high temperature environments.

● Steel Mill Industry

In steel production, cast pintle chain are used to transport heavy materials such as raw materials, furnace charges, steel and scrap. Cast chains can withstand high temperatures and heavy loads and are particularly suitable for the high-temperature smelting process in steel plants and the subsequent handling, cooling and distribution of steel.

● Wood Industry

Wood processing plants often use cast pintle chains when transporting and handling logs, wood cutting blocks or wood waste. These chains can not only handle heavy materials, but also adapt to the high humidity environment and corrosion problems common in wood processing.
