Roller Railcar Vibrators
Our line of pneumatic roller railcar vibrators offers a full range of frequency and force. With only three internal moving parts, these hopper railcar vibrators have an extended life and require minimal maintenance.

HOW IT WORKS: Air pressure activates the multi-slotted vane on two rollers (one within the other) which creates multiple vibrations on each orbit; this produces a powerful force at a high frequency.
KEY FEATURES:
- This series of roller railcar vibrators and shaker solutions is the industry standard for hopper railcar unloading.
- Mounts easily to most standard wedge brackets for use with hopper railcar pockets.
- There are no bearings, seals, or O-rings.
- 3 moving parts (vane, roller-vane, inner/outer roller) provide for simple, long-wearing vibration requiring minimal maintenance.
- Shaft, roller, and endplates are hardened and ground to assure high performance and reduced wear.
- Frequency ranges between 2000 and 9000 vpm depending on the type of railcar vibrator and air pressure applied.
- It produces a powerful output force ranging from 1000 pounds up to 7500 pounds.
