Mavi Maquinas Vibratorias has delivered a new type of car-shaker for 70 tons fertilizer railcars, called SmartShaker®. This kind of equipment will be used by Bunge Fertilizers in Brazil railcar unloading operations. A programmable electronic device allows to establish the vibration period to fully unload the cars. As construction characteristics are different (there are four types of 70 ton cars in operation) and every type responds differently to applied vibration, operators simply choose the type of car on a panel and automatically, after the car-shaker is positioned, the vibratory cycle starts according to its programmed time and frequency, automatically lifting off after the end of this procedure.

Cycle time and vibration frequency are fully adjustable. Furthermore the centrifugal force can be mechanically adjusted to optimize the unloading operations. No special drive is required as normal three-phase electrical motors have beeen chosen.
