Railcar & Truck Openers, Vibrators & Unloader.png

Railcar unloading sites are notoriously dangerous and dirty. Often they also form a bottleneck at the very beginning of the processing of powders or bulk solids. First, the gates of hopper bottom railcars are jammed shut. Opening them can be a challenging, time-consuming chore. Pry bars, come-a-longs, gate openers, and sometimes even torches are required. Next, comes the task of emptying the railcar. Either the hopper car materials won't flow at all or the flow is intermittent. Sledgehammers, rods, air lances, and vibrators are all employed. Too often, all are ineffective on the material you're attempting to unload. Finally, as the material flows from the car, dust envelops the site. The wind carries it to nearby buildings or the surrounding neighborhood. Now OSHA and the EPA are potentially involved in your operation.

Fortunately, it doesn't have to be like this. We at AIRMATIC can provide you with the products that will make your unloading site safer and more productive than it's ever been.
