Advantages of H78B chain：
The H78B Chain is a heavy-duty cast link conveyor chain designed for highly concentrated load transfer and material handling applications. Its robust cast steel construction and reinforced rooftop profile make it ideal for use in transfer conveyors, lumber handling, stackers, and trough systems operating under abrasive and continuous conditions.
Heavy Duty Construction – Engineered for rooftop and transfer conveyor systems carrying concentrated loads.
Cast Link & Reinforced Sidebars – Cast steel sidebars with high wear resistance for prolonged service life.
Rooftop (Camelback) Profile Design – Provides a stable top surface for conveying lumber, boxes, barrels, and similar loads.
Heat Treated Components – Heat treated pins improve overall strength and fatigue resistance.
Reliable in Abrasive Conditions – Suitable for tough industrial, forestry, and material handling operations.
Interchangeable with Standard H78B Chains – Compatible with equivalent chains from major manufacturers.

● 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.
