Forged link duplex Chain

Description

The forged link duplex chain is an ultra-heavy-duty conveying solution engineered for industrial applications that exceed the load capacities of standard single-strand chains. Featuring a reinforced dual-link (duplex) configuration and manufactured using advanced drop-forging technology, the duplex series provides nearly double the tensile strength and shock resistance of single-strand forged chains. This high-capacity architecture is specifically designed for extreme-load scraper conveyors, bulk material handling systems, and heavy-duty industrial elevators where structural integrity and maximum pull-out resistance are critical for continuous operation in severe-duty environments.

Manufactured from premium alloy steel with rigorous precision at every stage of the forging and heat treatment process, Hangzhou Ocean Industry's forged duplex chains deliver exceptional durability and minimal elongation under stress. Every chain is produced under ISO9001-certified management, ensuring the highest standards of dimensional accuracy and material consistency for mining, steel production, and heavy manufacturing facilities worldwide.

Key Features

• High-Capacity Duplex Architecture: the reinforced dual-link design significantly increases the overall tensile strength and load-bearing surface area, allowing for the transport of massive product weights over long distances

• Precision Drop Forged Construction: every component is drop-forged from high-grade alloy steel, creating a dense grain structure that offers superior resistance to fatigue, deformation, and link fracture under extreme tension

• Advanced Induction Heat Treatment: all links and pins undergo precision-controlled hardening processes to achieve maximum surface hardness on wear areas while maintaining a resilient, shock-absorbing core

• Superior Impact and Shock Resistance: the dual-strand configuration and forged material properties allow the chain to absorb massive shock loads from heavy material drop-on and frequent start-stop cycles in severe-duty lines

• Enhanced Lateral Stability: the wider duplex profile provides increased stability and prevents chain twisting or tilting, ensuring smooth and consistent movement through complex industrial conveyor paths

• Optimized Strength-to-Weight Ratio: designed to deliver extreme tensile strength while maintaining a highly efficient weight profile, reducing the overall power requirements for drive motors and minimizing stress on sprockets

• Custom Surface and Material Grades: available in various finishes and specialized alloy steel grades to withstand corrosive, high-temperature, or highly abrasive industrial environments such as mining and foundries

Application Range

• Heavy-Duty Scraper Conveyors — extreme-load transfer of bulk minerals, ash, and coal in power plants and mining operations

• Steel and Metal Processing — high-tension conveying of heavy coils, plates, and cast components through severe-duty zones

• Bulk Material Handling — high-capacity transport of sand, gravel, and aggregate in construction and quarrying facilities

• Heavy Machinery Assembly — transfer of large industrial sub-sections, engines, and transmissions across large-scale plants

• Foundry & Casting Operations — secure movement of massive molds and hot castings through severe-duty processing stages

• Industrial Elevators — high-strength vertical lifting of bulk heavy products where standard chains cannot support the total load

• Waste and Recycling Systems — reliable conveying of heavy industrial scrap, metal waste, and oversized recycled materials

• General Extreme-Load Conveying — any industrial line requiring the combined strength of forged steel and a duplex-strand configuration
