Railside Car Shakers

The NAVCO Railside Car Shaker is a permanently mounted vibration system designed to speed the loading and unloading of bulk material from railcars. The high-amplitude / low frequency vibratory energy developed by the drive mechanism has proven most effective in producing positive and complete material movement. The Railside Car Shaker is effective in loosening material from the railcar walls during unloading and in material densification during loading. The Railside Car Shaker facilitates a more “complete cleanout” of the railcar, reducing “carryback” material, and reducing average transportation costs in return.

The Rolling Railside Car Shaker extends to contact and shake the railcar as it rolls by (railcars do not need to come to a stop during operation). The unit features a contact surface made of composite slider blocks reinforced with heavy duty mechanical tubing to withstand the rigors associated with contacting moving cars and to provide maximum service life.

Both the stationary and rolling models are available in pneumatic or electric. They may also be operated from a remote location.
