Railcar Vibrators Offer High Force, Low Weight

Martin Engineering's portable vibrator activates the free flow of bulk materials from closed-top hopper railcars.

This portable vibrator activates the free flow of bulk materials from closed-top hopper railcars. With a high force to weight ratio, the Martin IMP3 impacting railcar vibrator delivers the power required to evacuate compacted bulk materials such as fertilizers, bentonite clay, Portland cement, grain, and other agricultural products.  

The vibrators improve workplace safety with little maintenance and a low cost of ownership. When a railcar is being emptied, the process needs to be fast, efficient, and thorough. Extra time spent unloading, manually cleaning, or sending cars back with material in them can translate into lost profits or increased costs. The higher the force to weight ratio, the more force is delivered to the material, increasing the efficiency of the vibrator.

The IMP3 was purpose-built for unloading dry powdered bulk materials. If vibrators fail, workers may need to resort to unsafe practices to get material flowing again, such as hammering on the cars or attempting to unclog them from the bottom of the hopper.

To avoid these expensive and potentially hazardous scenarios, the IMP3 produces 3000 vibrations per minute (VPM) and 3400 lb of force, which has been compared to a sledgehammer blow 50 times per second. The rapid impacts generate a vibratory wave through the metal hopper of the railcar, loosening adhered material to promote fast and even flow.
