Drag Conveyor Chains

Constromech’s Drag Conveyor Chains are engineered for horizontal and inclined conveying of abrasive, hot, and heavy bulk materials — such as ash, cement, clinker, coal, and minerals — within a sealed and controlled system. Whether your system requires a Single Strand Chain for compact conveyors or a Double Strand Chain for high-capacity, high-torque applications, we offer fully forged, case-hardened chain solutions built for long service life with minimal wear and zero compromise on performance.

Technical Highlights & Construction Features

FeatureTechnical Detail
Chain ProfileDrop-forged single/double strand links with wide shoulders for torque stability
MaterialAlloy steel with refined microstructure; hardened for abrasive and thermal resistance
Heat TreatmentQuenched and tempered; case-hardened to 40–50 HRC for high wear performance
Pin SystemPrecision-ground pins with positive locking and shock-load tolerance
Flight AttachmentWelded or bolted scrapers in flat bar, T-head, or U-type configuration
Pitch PrecisionTight tolerances reduce misalignment, noise, and premature elongation
Breaking LoadChains 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
