Technical Highlights & Construction Features
Chain Profile
Drop-forged single/double strand links with wide shoulders for torque stability
Material
Alloy steel with refined microstructure; hardened for abrasive and thermal resistance
Heat Treatment
Quenched and tempered; case-hardened to 40–50 HRC for high wear performance
Pin System
Precision-ground pins with positive locking and shock-load tolerance
Flight Attachment
Welded or bolted scrapers in flat bar, T-head, or U-type configuration
Pitch Precision
Tight tolerances reduce misalignment, noise, and premature elongation
Breaking Load
Chains proof-tested up to 3.2× rated working load
Single vs. Double Strand Chain – What’s Right for You?
Single Strand Drag Chains
Ideal for low to medium-load conveyors with tight spatial configurations.
- Compact and economical
- Smooth operation at moderate speeds
- Lighter construction — easier maintenance
- Recommended for ash, gypsum, and limestone systems
Double Strand Drag Chains
Built for extreme-duty performance in wide conveyors or high-capacity systems.
- Doubled link rows for higher load distribution
- Handles large volumes of hot clinker, coal, slag
- Greater torque transmission and scraper width
- Used in clinker coolers, bottom ash, and mining conveyors
Application Advantages
Suitable for fully enclosed conveying — reduces dust, spillage, and environmental exposure
Low elongation rate — less downtime for retensioning or adjustment
Compatible with Constromech and OEM sprockets and shafts
Available with flight wear pads, high-temp bushings, and abrasion-resistant options
Scraper designs tailored to material flow behavior and conveyor layout
