The oscillating mounting type ABI-HD is the "Heavy Duty" version in the AB mount family of the ROSTA screen suspensions. For example the ABI-HD type 50-2 offers 40 % more load capacity compared to the standard version AB 50-2 (14′000 instead of 10′000 N) by a slightly higher natural frequency (f = approx. 2,7 Hz instead of 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!
