Martin Engineering has introduced a portable vibrator that activates the freeflow of bulk materials from closed-top hopper railcars. With one of the highest force-to-weight ratios available in the marketplace, the Martin IMP3 Impacting Railcar Vibrator delivers the power required to evacuate compacted bulk materials such as fertilisers, bentonite clay, Portland cement, grain and other agricultural products.
Extremely high quality standards for the design deliver superior equipment reliability and long service life, allowing the competitively priced units to improve workplace safety with very little maintenance and low cost of ownership.
'When a railcar is being emptied, the process needs to be fast, efficient and thorough, because extra time spent unloading, manually cleaning or sending cars back with material in them can translate into lost profits or increased costs,' explained Marty Yepsen, Business Development Manager - Railcar Products, Martin Engineering. 'The higher the force-to-weight ratio, the higher the force delivered to the material, increasing the efficiency of the vibrator.'
The IMP3 is 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 3,000 vibrations per minute (VPM) and 3,400 lbs (1,542 kg) of force, which has been compared to a sledgehammer blow 50 times per second. The rapid impact generates a vibratory wave through the metal hopper of the railcar, loosening adhered material to promote fast and even flow.
