Rotary heavy duty cranked link chains chains were developed primarily for chain drive applications involving extremely large loads or particularly adverse operating conditions. Chains of the type are especially resistant to violent shocks, wear and severe operating conditions, and have as a result enjoyed increasing achievement in an array of applications recently.
For the most part, rotary chain dimensions are standardized under ISO 3512, ANSI B 29.10 and DIN 8182. One significant advantage of rotary chains is certainly that their links are constructed to the same design, making it simpler to lengthen or shorten the chains when required. 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 can be found in naturally hardened metal or special tempered steel, according to the expected mechanical load. Chains put through extremely high loads are fitted with induction-hardened pins, making them not only quite challenging, but also providing them with the highest possible degree of surface hardness.
