Type AB-HD

  • Description:

    The oscillating mounting type AB-HD is the “Heavy Duty” version in the AB mount family of the ROSTA screen suspensions. For example, the AB-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 AB-HD screen mount is the ideal suspension for mining- and aggregate screen working under variable charging capacities and are less sensitive to 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 AB-HD oscillating mountings are also available in stainless steel (AISI 304) and interchangeable with the blue AB-HD oscillating mountings!
