Fixes to common electric vibration equipment issues


Top-quality electric vibration equipment is an engineered solution that must be installed and operated properly (according to the manufacturer's instructions) in order to obtain maximum benefits.

In continuing efforts to ensure that users get the most out of its products, VIBCO Vibration Equipment shares with you some of the most frequent installation missteps and, of course, what you can do to fix it if any of these issues apply to your electric vibration application.

The top five most common electric vibration equipment performance issues are:


Vibration equipment is drawing high amps and kicking the breaker.


Vibration equipment is burning out after just a short time in operation.


Performance or useful life of replacement vibration equipment is significantly lower than previous equipment.


Vibration equipment fails shortly after being repaired.


Vibration equipment makes a humming noise, but does not run properly.



Most frequently, these performance issues are caused by one of the following mounting "missteps." For complete instructions on how to mount VIBCO electric units, please refer to the company's online manual.

1. The electric vibration equipment is mounted directly to the bin or hopper rather than to a mounting plate and mounting channel.

Mounting directly to the bin or hopper can cause the bin or hopper to crack, can cause damage to the vibration equipment, and can cause a high amperage draw. It is critical for vibration equipment to be mounted to a plate and channel.

2. The electric vibration equipment is mounted to just a plate or just a channel.

It is extremely important to mount vibration equipment in the manner recommended by the manufacturer. Vibration, while an effective material flow aid, can be a destructive force if it is not isolated properly. Using a mounting plate alone, or a channel alone, may not be sufficient to secure and isolate the vibration force exerted by the equipment. For best results, use a channel iron and mounting plate together.

3. The electric vibration equipment has been mounted in an incorrect position.

Electric units should be mounted perpendicular to the channel iron, and the mounting plate should be checked for warping and shimmed, if necessary, to achieve a tight seal. Any looseness or "give" will prevent the vibration force from being properly isolated. A sufficient length of channel should be used to distribute the force throughout the bin or hopper.

4. The welding, shimming and/or bolting of the vibration mount is problematic.

Mounting channel should be stitch-welded to the hopper or bin, with no welds on the corners of the channel. Welding on the corners of the channel can lead to bin damage and unit failure. All bolts should be tightened down securely to prevent slippage and all shims should be positioned to keep the mounting plate flat.

Your vibration mount is critical to maximizing the benefits of your equipment. To learn more about this topic, contact VIBCO at 800-633-0032.
