Railcar Vibrators & Shakers, and Hopper Car Gate Openers Railcar unloading sites are notoriously dangerous and dirty, and often a bottleneck at the very beginning of processing the powders or bulk solids needed for production. First, the gates of hopper bottom railcars are jammed shut, and opening them can be long, hard, and unsafe. The tag team of Slow and Dangerous rule the job. Pry bars, come-a-longs, gate openers, and sometimes torches are used. Next, the battle of emptying the railcar begins. Either the hopper car materials won't flow at all or the flow is intermittent. Sledge hammers, rods, air lances, and vibrators ineffective on the material being unloaded are used individually or in concert. Aggravation joins Slow and Dangerous to make the job even harder. Finally, as the material flows from the car, product-dust envelops the unloading site or is windblown to surrounding building or the neighborhood. OSHA and the EPA join the tag team. MARTIN® and WORKMASTER® Railcar Unloading Products enable you to beat the tag team that makes your unloading site unsafe and unproductive.
