Hopper Car and Hopper Trailer Shakers
Hopper Car and Hopper Trailer Piston shakers work like high-speed sledgehammers, noisy but effective, pounding against the wall of the car bin at high frequency to agitate the material inside. Use this shaker only where there are no noise restrictions, vibration duration will be brief, and where easy movement from bin to bin is important.
NOTE: The PCS-3 Hopper Car and Hopper Trailer Shakers can be modified to comply with force and design requirements set for the ACF “center-flow” hopper car, Contact us for details.
