Transfer Rooftop Chains are available in two types: “H” Class Transfer Chain and Combination Transfer Chain. “H” Class Transfer Chain includes those numbered H78A, H78B, H130, H131, and H138. All “H” Class Transfer Chain is available only in riveted construction. “H” Class Transfer Chain numbered H 78A, H 130, and H 131 is made with peaked roofs. Chain numbered H 138 and H 78B has flat roofs. The Combination Transfer Chain includes those numbered C55A, C55B, and C55D. It is available only in riveted construction with peaked roofs.

“H” Class Transfer Rooftop Chain is most often intended for operation in troughs, in two or more parallel stands on transfer conveyors, with only the bevel tops of the links projecting about the guides. This permits loading and unloading to be done transversely. The name “camelback chain” is used for this class of chain because of its ability to carry heavy concentrated loads, handle bulk material, and transport products. In industry, a rooftop transfer chain is the choice material to carry and transport lumber, boxes, barrels, crates, packages, barrels, bars, and so on.
