A Netter customer in the shipping and transport industry was experiencing difficulty in thoroughly emptying hopper cars of ash upon delivery. Because ash tends to retain some moisture, it was forming clumps and sticking to the inside of the car. Frequently, workers would have to dislodge the ash manually, which is time consuming and risky, or the trains would simply return without completely emptying the car.
The customer purchased an NHW 7000 hydraulic vibrator and, using a front loader, applied the vibration to the hopper car while it was being unloaded. This shook the ash off of the sides and bottom of the car, allowing it to fall freely out of the car. As a result, the car is emptied faster, and because it is emptied thoroughly, it can be re-filled completely, allowing more material to be delivered with each trip.
