Description
NAVCO Overhead Railcar Shakers are designed to facilitate the unloading of bulk materials from open-top hopper railcars at transfer terminals and points of use. NAVCO Overhead Railcar Shakers utilize applied vibration technology to efficiently drive energy into the railcar, resulting in the release of the bulk material, and assuring fast, safe, and complete unloading of the railcar. Typical applications include the unloading of:
- Aggregates and sand
- Coal
- Mined ore and minerals
- Coke
- Biomass
The heavy-duty industrial design of NAVCO Overhead Railcar Shakers makes them the right choice for the most difficult railcar unloading challenges. At the heart of the railcar shaker is a short shaft modular vibrating drive. The vibrating drive is directly coupled to the AC drive motor powering the shaker. The direct-drive technology eliminates the need for the constant adjustment and slippage of the old belt drive standard.
The power train of the shaker works to lift and drop the massive chassis approximately 1/8 inch per cycle. The impulse developed when the shaker contacts the railcar on the downstroke of each cycle initiates and maintains material flow for the most stubborn materials. The NAVCO Overhead Railcar Shaker features a rugged, stress relieved construction that provides many years of low maintenance service in harsh environments. NAVCO’s unique control packages enable operating adjustments to be made in real-time for specific application challenges.
NAVCO Overhead Railcar Shakers feature:
- Heavy steel construction normalized prior to assembly for stress relief and long life
- Modular sealed gear box exciter drive with close coupled bearings for low shaft deflection and long life
- Direct coupled cardan drive shaft – eliminating belt replacement or tensioning maintenance issues
- Bolted modular components allow easy access for maintenance or replacement
- Variable frequency drive allows simple operating adjustments to changing unloading conditions
Additional Benefits
- Increases worker safety
- Reduces labor costs
- Faster unloading of even the most stubborn material
- Low maintenance, long service life
