Drag Conveyors

Move Material Efficiently with Hapman Drag Conveyors and the Industry’s Most Durable Chain

Hapman drag conveyors move material over distances ranging from 20 to 200 feet or more. These conveying systems are equipped with the industry’s most durable chain, built with an exclusive drop-forged, case-hardened formula that produces a hard exterior coupled with a softer, malleable core. This combination gives our conveyor chain the highest level of abrasion resistance while reducing the risk of stress and breakage.

Drag Chain Conveyors

Engineered with the specific features required for each individual application. Conveyor size, flight selection, single- or dual-chain layout, housing, diverting discharge ports, high-temperature components and other key options will be evaluated by our design team and included as necessary to effectively move all of your material.

En-Masse Drag Chain Conveyors

Conveying with En-Masse Drag Chain Conveyors gives you the ability to move large volumes of material in virtually any direction or layout. The flexibility in engineered design means we can provide the optimum conveyor layout to achieve all of your bulk material handling and operating goals.

Size to capacity ratio – A typical belt conveyor uses 20-25% of available conveying space to move bulk material. A typical drag or paddle conveyor uses 45-50% of available conveying space. En-Masse Drag Chain Conveyors use 90% of the available conveying space to effectively move material.

Ability to handle product in many conveyor configurations – Horizontal, inclined, vertical, L-path, Z-path and looping are all possible with an En-Masse Drag Conveyor.

Ability to convey over long distances – En-Masse Drag Chain Conveyors can effectively move material an average of 200 feet (61 meters) or more.

Engineered for a wide range of bulk material handling – From ash to zinc, the design of an En-Masse Drag Conveyor allows for large volumes of material to be moved efficiently and effectively.

Additional Options

  • Impact and Wear Resistance – The chain in our Drag Chain Conveyors is case-hardened with a strong ductile core. This engineered balance between exterior hardness and a malleable interior provides the right wear resistance without becoming brittle.
  • Fatigue – Our chain design proportions the steel where needed and features dropped-forged steel alloy links constructed to avoid premature wear.
  • Bearing Surfaces and Finish – Our bearing and surface finish process significantly limits joint articulation wear with precision machining and tight tolerances.
  • Manufacturing Techniques – We maintain strict dimensional tolerances and documented quality control procedures. We select the proper alloys for the application and have a proven system in place to verify production according to established standards.
  • Flight Attachment Method – Our flight assemblies are welded and bolted for superior durability, even in severe conditions.
  • Chain Weight and Pitch – We develop, design, and engineer our chains specifically for En-Masse drag conveying operations in order to achieve the appropriate strength-to-weight ratio for maximum longevity.
