The Industrial Vibrators from Global Manufacturing, Inc. work best when applied to an industrial hopper or bin as it unloads. They're also highly effective when unloading materials that comprise small plastic parts or electronic components such as grain or corn in agricultural applications - or even pills in a pharmaceutical plant.
The vibration breaks the static bonds that often build up between your product and the walls of the container. It also shakes loose the particle-to-particle friction in bulk solids like powders, aggregates and sand.
Industrial Electric Vibrators
Quiet Thunder® Electric vibrators, single-phase, three-phase models, 12-Volt, and 24-Volt models are rotary vibrators. They use an electric motor to rotate shaft-mounted unbalanced weights to produce vibration. The speed of the rotation and the size of the unbalanced weights determine the force pound output.
Rotary electric vibrators are non-impacting. When properly installed, it transfers the vibration through the hopper wall or truck bed to the material inside, without flexing the structure. Rotary vibration causes displacement of the material away from the hopper wall, allowing the material to slide from the hopper.
Frequency and force of the vibration restores material flow. Electric vibrators are much more quiet and efficient than pneumatic or hydraulic rotary vibrators. They are especially useful where air or hydraulic power sources are not available and where quiet operation is necessary.

Quiet Thunder® Electric Vibrators AC Models
Quiet Thunder® Electric Rotary Vibrators operate on alternating current (AC). They are especially useful where air or hydraulic power sources are not available. A major advantage of electric vibrators is they are extremely quiet.
The only noise is the hum of the electric motor. Global's QT and DEG Series electric vibrators are available in 2-pole (3600 RPM), 115, 230, & 460 voltages, 60 Hertz, and single or three-phase AC current. Single phase vibrators are only available in 115 Volt.

Quiet Thunder® Electric Vibrators DC Models
The 12 and 24 Volt CEG Series Rotary Vibrators operate on direct current (DC). Global has 12 and 24 Volt Vibrators, either continuous duty or intermittent use. DC vibrators are especially useful where air, hydraulic, or AC power sources are not available.
A major advantage of DC Electric Industrial Vibrators is they are extremely quiet; the only noise is the hum of the electric motor. The CEG Series DC Vibrators are an excellent choice for Dump Trucks, Feed Hoppers, Seed Tenders, Hopper Trucks, Fertilizer Spreaders, Concrete Pump Trucks, Salt Spreader Hoppers and many more.
The largest CEG DC Vibrator can handle a load up to 41,820 pounds (19,000 kg). Use multiple vibrators on a single hopper when the load is greater than 41,820 pounds (19,00 kg).
For example, to restore flow to a hopper or truck bed of 86,000 pounds (39,000 kg), use two CEG DC Vibrators. If unloading a truck bed, you may size down according to what it left in the bed after it is dumped. But if you turned the vibrator on with a full load, you must size vibrator for the full load.

Industrial Hydraulic Vibrators
Our Hydraulic Design Series rotary industrial vibrators use an external hydraulic motor to drive the shaft mounted eccentric weights (the “unbalance”) to produce vibration. Because of their separate motor these vibrators can produce substantial force with moderate frequency.
Hydraulic motor driven vibrators are larger and produce significantly more force than some of our other vibrator models. The largest Hydraulic Design Series Vibrator can handle a load up to 355,000 pounds (161,000 kg) at a flow of 15.1 gpm (57 lpm). Use multiple vibrators on a single hopper based on the dimensions of the hopper and material weight.

Advantages of Hydraulic Motor Driven Rotary Vibrators
- Rugged Construction - Ductile iron housings and lightweight hardened aluminum covers.
- Vibrator Component Alignment - All manufactured equipment contain slight alignment variations due to manufacturing tolerances. Global’s Design Series vibrators have an unique drive coupling design, to compensate for typical alignment variations that exist when two shafts are connected (motor shaft and vibrator shaft). The coupling keeps the vibrational stress off the motor shaft seal. This prevents the motor from leaking because if the motor shaft is allowed to vibrate it would slowly destroy the seal making it ineffective. Some competitive vibrators use the conventional ‘shaft-in-a-shaft’ design; the drive motor shaft slips into the vibrator shaft. This design works only if both shafts remain in perfect alignment regardless of operating conditions. This arrangement often causes motor shaft flexing and fretting within the vibrator shaft, which leads to premature motor failure and a worn out vibrator shaft.
- Drive Coupling Assembly - The drive coupling allows the motor shaft and vibrator shaft to operate as an "assembly", preventing fretting and stress from misalignment or expansion. Any misalignment or expansion wear takes place in the inexpensive and easily replaced coupling rather than in the motor or vibrator shaft. This superior design protects the motor shaft, vibrator shaft, bearings and seals from the vibration of the unbalanced weights. The result is better performance, no leaks, longer service, and reduced operating costs.
- Bearings - All bearings are sealed to keep grease in and contaminants out. Our unique oil lubrication system in the D7 and CC7 models helps extend the life of the bearing. The coupling design isolates the unbalanced load from the motor, so the motor bearings see only a balanced load, extending bearing life. Grease lubrication is also available.
- Hydraulic Motor Shaft Seal is isolated from the unbalanced load by the unique coupling design, extending the life of the seal and preventing hydraulic leaks.
- High Efficiency - Durable, Bi-rotational Hydraulic Motor.
- Hydraulic Motor Repair Kits available to return the motor to like-new condition.
- Easy Repair and Maintenance - designed for easy change-out of bearings, motors, couplings, and other components to refurbish Design Series vibrators to like new condition. Bearings, o-rings, retaining rings, etc. are standard, commonly available parts.
- High Amplitude, Moderate Frequency vibration.
- Versatile - Easy to control force and frequency by adjusting flow of the hydraulic oil.
- Available in Permanent Mount and Portable Clamp-on Mount. Clamp-on vibrators use square head set screws with concave cup points for positive self-locking and vibration resistance.
- Produces Uniform, Directional Flow.
Industrial Pneumatic Vibrators
There are many types and sizes of Rotary and Piston air vibrators. Global Manufacturing’s Customer Service team can assist you in the selection of the best type and size of industrial pneumatic vibrator for your particular application.
Usually, the smaller the structure, with a bulk flow problem, the smaller the air vibrator you need. Also, industrial vibrators work in harmony. If the application calls for 1000 force pounds to solve the flow problem, two vibrators generating 500 force pounds each will work.

Pneumatic Rotary Vibrators
Rotary air vibrators produce a sinusoidal wave of energy that is used to restore flow to bulk materials. Compressed air turns an 'unbalanced' weight, ball, roller, or turbine wheel to produce this sinusoidal wave of energy, which produces the vibration. The larger the "unbalance" and the faster it turns, the greater the centrifugal force produced.
When properly mounted, the vibration is transferred through the hopper wall to the material inside, without flexing the structure. Also, proper mounting disperses the rotary vibration over a large area producing uniform material flow. As the material vibrates, it is displaced from the hopper wall.
The sinusoidal wave reduces the friction between the wall and the bulk material, allowing gravity to restore material flow. Rotary vibrators are non-impacting. Since rotary vibration is directional, material will be encouraged to flow toward the rotating 'unbalance'.

Pneumatic Piston Vibrators
Piston air vibrators, also called linear vibrators, produce shock waves of energy much like an automatic sledgehammer. Piston vibrators use the impact action produced by the oscillating piston to flex the bin wall. This flexing action loosens material stuck to the wall, thus restoring material flow.

Advantages of Pneumatic Vibrators
- Most factories have available air to use.
- Easy to install - no electrician needed.
- Hassle Free - very forgiving of a poor mount.
Pneumatic Rotary Railcar Vibrators
Rotary vibrators, especially high-speed models, unload fine particulate bulk solids, such as limestone fines, more efficiently than piston impacting vibrators. The high speed ‘liquifies’ the material. After unloading, the vibrator may become wedged in the railcar pocket.
The best way to dislodge the vibrator is to use our unique Hammer Strike Plate. Operators often use a large hammer and hit the vibrator, causing damage. The GBMX Bracket features a heavy-duty strike plate, which extends below the railcar bracket. The hammer blow is directed to the strike plate and not to the vibrator.
