Gravity alone won’t empty a hopper car loaded with wet limestone, compacted base material, or sticky fines. And the longer you wait, the more time you burn per car across the full train. The NAVCO Railside Railcar Shaker uses controlled vibration to move material that gravity can’t — eliminating bridging, rat holes, and compaction. It’s cut unloading time by up to half in several applications.
