ROSTA oscillating mountings type ABI are maintenance-free elastic rockers for the support or suspension of freely oscillating vibrating equipment with a wide variety of designs and drive systems. They assist the driving forces in the conveying direction and assure good linear guidance of the oscillating part of the machine. The pantograph structure of the oscillating mounting allows large spring deflection under load, which results in low natural frequencies (down to approx. 2.2 Hz) and hence exceptionally high insulation efficiency towards the support structure. The great lateral stability of ROSTA oscillating mountings prevents the wobbling of the screen casing typical of helical spring mountings on passing through the resonant frequency.
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!
ROSTA anti-vibration mounts type ESL are intended for the absorption of medium and low frequency vibrations and are designed to accept compression, tension and shear loading as well as combined loadings. They can be installed in any desired position and are also ideal for ceiling and wall mounting.
