US Type "A" chains are used... on the American continent.
However, they have not been adopted by many European manufacturers.
Their use is therefore mainly limited to equipment and machines designed or built according to US standards.
Les plaques de la série "H" sont beaucoup plus épaisses, ce qui confère à ces chaines une résistance à la fatigue très nettement supérieure (+ 35 à 45% environ) et une capacité à transmettre de fortes charges dynamiques sans déformation.
