New Oscillating Mount from Lovejoy
December 25, 2003— [photo] The ROSTA AB oscillating family from Lovejoy is an upgrade of the heavy-duty AB mounts in order to perform lighter operation with the same type of shock absorption.
According to the company?s press release, the new mount eliminates resonance by compensating for the resonance shaker screens experience during startup and shutdown.
The mount was created specifically for free oscillating screens and shaker conveyor suspensions with drive frequencies below 12 Hz. Two series of connected ROSTA double rubber suspensions are comprised in the mount and offer an isolation rate of 98% toward sub frame and building structure with a natural frequency of 3.6?3.2
