698HT Forged Rivetless Chain

Description

The 698HT forged rivetless chain is a premier high-strength industrial solution engineered for the most demanding high-tension overhead conveyor and trolley systems. Built using advanced drop-forging technology and a unique "rivetless" design, the 698HT series allows for rapid assembly and disassembly by hand without the need for specialized tools. The "HT" (Heat Treated) designation signifies that every component — including the center links, side links, and pins — has undergone rigorous induction or through-hardening processes to maximize tensile strength and wear resistance. This makes it the definitive choice for severe-duty industrial applications requiring high-load capacity and maximum structural reliability in continuous-flow production environments.

Manufactured from high-performance alloy steel with precision-controlled forging and heat treatment, Hangzhou Ocean Industry's 698HT chains provide exceptional durability and minimal elongation under stress. Every chain is produced under ISO9001-certified quality management, ensuring the highest standards of dimensional accuracy and material consistency for automotive paint lines, steel mills, and heavy-duty manufacturing facilities worldwide.

Key Features

• Tool-Free Rivetless Design: the unique link and pin geometry allows the chain to be assembled and disassembled manually, significantly reducing downtime and labor costs during installation or maintenance

• High-Tensile Drop Forged Construction: every component is drop-forged from premium alloy steel, providing superior structural integrity and the ability to handle massive shock loads and continuous high-tension operation

• Precision Heat Treatment (HT): all links and pins are heat-treated to a specific Rockwell hardness, ensuring a tough core and a wear-resistant surface that dramatically extends the service life in abrasive industrial environments

• Three-Dimensional Articulation: the specialized link architecture provides excellent flexibility in both horizontal and vertical planes, allowing the chain to navigate tight curves and elevation changes in complex overhead layouts

• Optimal Strength-to-Weight Ratio: designed to deliver maximum tensile strength while maintaining a relatively low weight, reducing the overall power requirements for drive motors and minimizing stress on track components

• Standard Compatibility: the 698HT series is manufactured to international industry standards, ensuring full compatibility with existing 698-series sprockets, trolley brackets, and overhead conveyor tracks

• Advanced Customization Options: available with specialized coatings (such as zinc or chrome plating) and various attachments (pusher dogs, flights, or brackets) to meet the unique operational requirements of your conveying system

Application Range

• Automotive Assembly Lines — high-tension overhead paint lines, body-in-white transfer, and final assembly conveyors

• Steel and Metal Processing — heavy-duty transfer of coils, plates, and cast components through high-temperature zones

• Slaughterhouse & Meat Processing — reliable, easy-to-clean overhead systems for high-volume processing and cooling lines

• Construction Material Manufacturing — curved handling of bricks, tiles, and heavy building products in firing and drying ovens

• Heavy Machinery Production — transfer of large engine parts, transmissions, and industrial sub-sections during assembly

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

• Logistics and Bulk Material Handling — high-capacity overhead sorting systems for oversized freight and industrial containers

• Agriculture & Fertilizer Plants — durable conveying in corrosive and abrasive environments where maintenance access is limited
