Rotary heavy duty cranked link chains chains were developed primarily for chain drive applications involving extremely heavy loads or particularly adverse operating conditions. Chains of this type are particularly resistant to violent shocks, wear and severe operating conditions, and also have as a result enjoyed increasing achievement in a wide range of applications in recent years.
Generally, rotary chain dimensions are standardized under ISO 3512, ANSI B 29.10 and DIN 8182. One significant advantage of rotary chains is usually that their links are all built to the same pattern, making it simpler to lengthen or shorten the chains when necessary. They have another advantage over standard roller chains – all links are at the mercy of the same level of wear.
ELITE rotary chains with cranked links are fitted with cotter pins. The chain plates can be found in naturally hardened steel or special tempered metal, according to the anticipated mechanical load. Chains subjected to incredibly high loads are fitted with induction-hardened pins, making them not only extremely tough, but also giving them the highest possible degree of surface hardness.
