Il supporto oscillante tipo ABI-HD è la versione "Heavy Duty" della famiglia di supporti AB delle sospensioni per i vagli ROSTA. Ad esempio il tipo ABI-HD 50-2 offre il 40% in più di capacità di carico rispetto alla versione standard AB 50-2 (14.000 invece di 10.000 N) grazie a una frequenza naturale leggermente superiore (f = circa 2 HZ invece di 2,3 HZ)
The ABI-HD screen mount is the ideal suspension for mining- and aggregate screen working under variable charging capacities and are less sensitive on possibly occurring overload situations. Furthermore, due to the high load capacity, these mountings are also predestined for screens submitted to impact loading situations (e.g. charged by front-end loaders).
All ABI-HD oscillating mountings are in stainless steel (AISI 304) and interchangeable with the blue AB-HD oscillating mountings!
