Rotary heavy duty cranked link chains chains were developed mainly for chain drive applications involving extremely large loads or particularly adverse operating conditions. Chains of this type are particularly resistant to violent shocks, wear and extreme operating conditions, and also have as a result enjoyed increasing success in an array of applications recently.
Generally, rotary chain dimensions are standardized under ISO 3512, ANSI B 29.10 and DIN 8182. One significant advantage of rotary chains is definitely that their links are all built to the same design, making it simpler to lengthen or shorten the chains when necessary. They have another benefit over regular roller chains – all links are at the mercy of the same degree of wear.
ELITE rotary chains with cranked links are fitted with cotter pins. The chain plates are available in naturally hardened metal or special tempered metal, according to the expected mechanical load. Chains put through incredibly high loads are installed with induction-hardened pins, making them not only quite challenging, but also giving them the highest possible level of surface hardness.
