The ASCMA (now the American Chain Association), recognizing the need for a complete standard providing intercoupling and direct replacement of chains of different manufacture, established this Standard utilizing the minimum number of chains to meet requirements of industry for the chains widely used in conveyor and elevator applications.
The “H” type mill chains (B29.14M) are a derivative of the malleable detachable chains and were developed to meet the demands of heavier duty service.
These chains were developed principally for the lumber and pulp and paper industries for drives, transfer, and drag conveyors. They are also well adapted to elevator service of moderate speeds and loads.
Interchangeability between chains of various manufacturers is important with the widespread usage of these chains.
