I. Introduction
You have purchased a GCL-4400/GCD-4400, GCL-5000/GCD-5000, GCL-5500/GCD-5500, or GCL-6500/
GCD-6500 High Frequency vibrator manufactured by Global Manufacturing, Inc.®They are excellent
roller style high frequency pneumatic vibrators used on forms for concrete consolidation. The GCL model
ts the standard cradle lug brackets commonly used on concrete forms. The GCD models are bolt-on for
a more permanent mount, although they can also be attached to portable brackets.
For optimum performance, cycle the vibrator on and off. Vibrator act as a friction reducer and once the
bulk solid is set into motion, gravity does the rest. Do not operate the vibrator on an empty hopper as
this may cause structural damage to the hopper. Operate vibrators only when discharge gates are open.
Vibration will compact the material inside the structure if the discharge gate is closed.
Vibration has two important elements – Frequency and Amplitude. Frequency is the speed (RPM) or the
number of vibrations per minute. It is controlled by the air ow to a pneumatic vibrator. Amplitude is
the unbalance or amount of force produced by the eccentric weight. The faster the eccentric weights turn
the more force output generated. Force and frequency work together. It is not necessary to use a lot of
force when you have adequate frequency.
• Follow all mounting instructions.
• Always use a safety cable or chain for support.
• Do not operate vibrators when structure is empty.
• Do not operate vibrators when gate is closed or conveyor is stopped unless consolidation of
material is desired.
• Wear ear protection for 90+ decibel levels.
• Do not operate the pneumatic vibrators above 100 p.s.i.
• To prevent explosive hazard, do not use combustible gases to drive the pneumatic motor.
• Do not use hydrocarbons (fuel or kerosene) as a lubricant or de-icer.
• Always operate pneumatic vibrator with a regulator, lter, and lubricator.
• Always disconnect air line before maintenance.

II. Installation Procedures
The key to successful
vibration is a proper mount
because rotary vibration
resonates the material
inside the structure, when
the vibrator is mounted
correctly. Rotary vibrators
should appear motionless
and make minimal noise.
Do not mount the vibrator directly to the
structure wall. Use a channel iron stiffener for
proper mount rigidity and as the transducer of
the vibrational energy.
Channel Irons - Size & Mounting
Install channel iron at least two-thirds the height
of the sloped portion of the hopper, but not less
than 6 feet (1.83 m) in length and the width not
less than the base width of the vibrator. See
chart below for recommended channel sizes. Do
not install more than one vibrator on the same
channel iron or use a channel iron shorter than the
recommended length. A short channel may ex
the bin wall.
Attaching the vibrator to the channel iron.
Stitch weld nuts to the back of the channel iron
or the channel iron may be drilled and tapped to
accept the mounting bolts. An alternate method is
to cut a second channel iron slightly longer than
the footprint of the vibrator. Stitch weld the second
channel iron to the rst. Do not weld the ends.
Mount the vibrator to the second channel iron.
Stitch weld the channel iron vertically to the
sloped portion of the bin wall. Weld 3 inches
(7.5 cm), skip 1 inch (2.5 cm), weld 3 inches (7.5
cm), etc... Leave 1 inch (2.5 cm) un-welded on
the ends and corners. This allows the vibration to
dissipate out the ends of channel without causing
stress cracks to the hopper or bin. By doing so,
should the weld fail, the entire mount will not fall
off. Do not mount the channel iron horizontally.
Secure the vibrator to the channel iron with
SAE coarse thread grade 8 plated bolts with
lock washers or an adhesive such as Loctite®
262. Tighten bolts in a sequential process. At least
two passes are required in most situations. Give
all bolts the same torque value. Grade 8 bolts can
handle more torque than standard bolts. If Loctite®
is not used, retorque the bolt after the vibrator has
operated for a few minutes and check tightness
often. If Loctite®is used do not retorque the bolts
as this will break the Loctite®bond.
Attach a safety cable to a stronghold (not the
channel iron mount), which is higher than the
mounted vibrator and capable of holding the
vibrator’s weight.
Install a channel iron that is at least two-
thirds of the height of the sloped portion of
the hopper but no greater than 10 feet (3 m).
Important!
Caution!
Mounting GCL cradle lug model - Stitch weld a
GCL Bracket to the back of the channel iron. Do not
weld the ends. Mount the vibrator in the bracket by
sliding the foot into the GCL Bracket, lowering the
latch bolt into the ngers on the vibrator housing,
and securely tighten the nut.

III. Mounting Locations
Install a channel
iron stiffener on
the outside of the
sloping wall 1⁄3the
distance above the
discharge opening.
Multiple Vibrators
Use more than one vibrator when the diameter or
width of any wall is greater than 12 feet (3.66 m).
Always mount the vibrators on different planes.
Two Vibrators on Round or Square Hoppers
Install channel iron stiffeners 180° apart. Install
one vibrator on the outside of the sloping wall 1⁄3
the distance above the discharge opening. Install
the second vibrator on the outside of the opposite
sloping wall 2⁄3the distance above the discharge
opening.
Two Vibrators on Rectangular Hoppers
Install channel iron stiffeners on opposite sides of
the long walls. Install one vibrator on the outside of
the sloping wall 1⁄3the distance from the discharge
opening. Install the second vibrator on the outside
of the opposite sloping wall 2⁄3the distance above
the discharge opening. When only one wall slopes,
mount both stiffeners on it. Equally space the
stiffeners on the wall. Place one vibrator 1⁄3 above
the discharge opening on one channel iron and the
other vibrator 2⁄3above the bin’s discharge opening
on the second channel.
Three Vibrators
Install channel iron stiffeners mounted 120° apart.
Install the rst vibrator on the outside of the
sloping wall ¼ the distance above the discharge
opening. Install the second vibrator on a separate
channel iron at ½ the distance above the discharge
opening. Install the third vibrator on the remaining
channel iron at ¾ the distance above the discharge
opening.
Installation on Chutes and Flow Pipes
Mount channel iron stiffeners vertically or in the
direction of material ow. Center the channel if the
chute is less than 6 ft (1.83 m) in width. If the
chute is greater than 6' in width, use two vibrators
on separate channel irons. To maximize each
vibrator’s radius of inuence; center each channel
iron in each half of the chute. Each channel iron
should be located ¼ of the chute width from the
edge and ½ of the chute width apart. (e.g. –
a chute 8'wide, the channel iron locations would
be 2'from each edge and 4'apart.) When wall
thickness is less than ⅛", additional reinforcement
may be required.

Installation on Railcars
Place GCL vibrator in a GCL-GBMX Bracket or a
GCL-GBM Bracket. The vibrator on the bracket slides
into the standard railcar bracket on the hopper car.
If two vibrators are used on one railcar, use an air
regulator to run them at different speeds.
Placement on Channel Iron
Orient the direction-of-rotation of the unbalance
(roller weight) so that it turns in the direction of
material ow. Position lug bolt on the high side
(uphill side) of the channel iron.
Mounting on Truck Bed
Weld GCL bracket to an independent channel
iron. The GCL vibrator inserts quickly into bracket.
Locate the channel iron as close as possible to the
material flow problem area.
Securing Vibrator to GCL Bracket
Attach the vibrator to the cradle lug bracket by
placing the tab at the base of the vibrator under
the bar on the end of bracket. Rotate the vibrator
towards the bracket until it is fully seated. Rotate
the bracket bolt until it ts between the two ngers
on the vibrator housing and secure it using the
cradle lug nut. Use a standard open-end or box
wrench to tightened. Repeated tightening with an
air wrench will eventually cause excessive wear to
the ngers on the vibrator housing.

IV. Operation
Global High Frequency External Vibrators are
pneumatic with dual rollers. Their ease of operation
and low maintenance is due in part to the fact that
these vibrators contain no bearings or motors.
The vibrator may run continuously at speeds
up to the rated running conditions shown in our
performance data. Use a ball valve or solenoid
valve to turn the vibrator on and off. A regulator
provides constant speed control even as the plant
air pressure varies.
Install a filter, regulator, gauge, and lubricator in
the air line within 10 to 12 feet (3 - 3.7 m).
Filtration
Do not connect the vibrator directly to plant air. Use
a 64 micron filter. Drain the airline filter regularly
and examine the element for signs of clogging.
Regulation
Operate the vibrator on ltered, regulated, lubricated
air between 40 - 80 psi (2.8 - 5.5 bar) at 45 - 60
cfm (21 - 28 Lps).
Lubrication
Use a lightweight lubricant. Replenish the airline
lubricator as required and set to give the following
drop rate minimum. Will operate in temperatures
of 32° F (0° C) to 250° F (120° C).

Pipe and Hose Connections
The vibrator has a barb tting to accept a ¾"
I.D. hose. Clamp the hose securely to the tting
with a Band-It, Punch-Lok®, or a similar clamp. A
worm driven clamp is not recommended since the
vibration may cause the clamp to loosen and allow
the hose to blow off the fitting.
The table below shows the recommended hose size
according to the amount of air required.

If the vibrator will be moved or disconnected
frequently, a hose whip is recommended (see
illustration below). The whip is a short piece of hose
(12" - 18") atttached to the shaft with a clamp.
Attach a quick coupling, such as a Dixon®hose
coupling, to the free end of the whip. Add a ball
valve to the plant air line to shut off the air before
disconnecting the quick coupling.
V. Assembly & Disassembly
For proper vibration operation, it may be necessary
to change the direction of rotation or the position
of the vane. Both the GCD and GCL models are
disassembled and assembled in the same manner.

Disassembly:
Note 1: The vibrator shaft is pressed into the
side plates. The side plates have a slip t in
the housing.
1. Remove the four ⅜" hex bolts and lock washers
from each side plate.
2. Opposite the air inlet, using a press, carefully
press against the backside of the shaft. This
will push out the (exhaust) side plate and the
shaft (as one assembly). Protect the air inlet
connection. The inner and outer rollers will
come out with the shaft. Remove blind side
plate if necessary.
3. Lift air vane from shaft. Inspect side plates,
shaft, and vane for wear. Any grooving on the
side plates or noticeable wear on the inner
roller, shaft, or vane requires component
replacement.
Assembly:
It is important to keep in mind the mounted
orientation of the vibrator. The vane and side plates
must be properly positioned to place the vane on
top of the shaft to give the proper direction of
rotation when mounted.
Note 2: Below is an exploded view of the GCD
vibrator. Notice the position of the blind side plate,
which has three slots milled halfway through
the plate, and the exhaust side plate, which has
three slots milled all the way through the plate.
The slots of the side plates must be directly
across from each other. These plates must be
positioned with the grooves in the vane facing
away from these three slots.
1. Assemble the shaft. Press or tap the keys into
the keyways in the shaft. Place the vane in the
shaft so that the grooves in the vane will be
facing away from the three milled slots of each
side plate. See page 11 for orientation of vane.
2. Exhaust side plate installation: Using the key as
a guide, align the shaft/key with the keyway on
the exhaust side plate. Press air inlet end of the
shaft into the exhaust side plate until it stops.
3. Install the exhaust side plate/shaft assembly
into the vibrator housing. Be sure its orientation
will place the vane on top of the shaft and
give the desired direction of rotation when the
vibrator is in the mounted position. Align the
bolt holes in the side plate with the threaded
holes in the vibrator housing. Install the hex
bolts and lock washers with Loctite® 262 and
tighten the bolts to 33 ft·lb torque (44 Nm).
4. Make sure all foreign material is out of the
vibrator housing and the rollers. Place the
rollers on the shaft inside the housing. Place
smaller roller inside the larger roller.
5. Press the blind side plate onto the end of the
shaft and into the vibrator housing. Align the
bolt holes and the keyway of the blind side
plate. Install the hex bolts and lock washers
with Loctite® 262 and tighten the bolts to 33
ft·lb torque (44 Nm).

VI. Vibrating Wet Concrete
Concrete Consolidation by vibration is achieved by
adding a mechanically-induced combination of force
and frequency allowing those forces to act on the
freshly-poured concrete within the vibrator's area
of inuence. The proper combination of force and
frequency will ensure that the concrete will retain
its homogeneity while allowing the entrapped air to
escape through the surface. A frequency of 9,000
– 12,000 vibrations per minute initiates resonance
in (or “excites”) the cement, causing the ultra-ne
cement particles to release the extremely small
air pockets that have adhered to the cement, so
that the mortar lls in all of the spaces around the
aggregate. Vibration evenly distributes the cement
and aggregates resulting in a more dense and a
smoother concrete nish.
When enough of the entrapped air has risen to the
surface to achieve concrete consistent with the
intended strength of the mixture, the vibration is
complete. In practical terms, it is neither possible
nor necessary to remove all of the entrapped air in
the consolidation process.
How to Select an External Vibrator
There is not an exact method or science when using
external vibrators for concrete consolidation. Mixes
vary, and therefore, consolidation procedures and
preferred vibrator styles vary. “Experts” become
experts through trial and error. What makes every
application different is that the mixes will vary due
to the slump, any chemical additives, aggregate
sizes/shape, cement content, consistency of the
mixture, weather conditions, and even the type of
form work used. Following these general rules may
be helpful in selecting the number and placement
of external vibrators for effective concrete consoli-
dation.
In selecting External Vibrators, the contractor
should initially consider the workability of the
concrete and the rigidity of the forms. Plastic
concrete (slump > 3") responds better to high
frequency vibration, while stiffer mixtures
(slump < 3") require higher amplitude vibration to
initiate uidization. While properly-sized external
vibrators can be successfully used on virtually any
concrete formwork, using a too-powerful vibrator
on lightweight forms can cause damage to the
formwork. This has caused some contractors to
mistakenly believe that external vibrators cannot
be used on lightweight concrete formwork.
Vibrator Selection
Depending on specic conditions, external vibrators
with speeds between 3,000 and 12,000 rpm may be
suitable for form vibration. However, because the
natural resonant frequency of Portland Cement is
between 9,000 – 12,000 rpm, pneumatic vibrators
are often the only equipment capable of delivering
this necessary frequency.
After determining the approximate combined
weight of the formwork and concrete to be vibrated,
the contractor should select a vibrator producing the
amount of force specied by the table below. It will
often be necessary to use more than one vibrator
to produce the total amount of force required.
Note: If specific density of the concrete is
unavailable, use a standardized weight of 150 pounds
per cubic foot (2,400 kg / m3) for approximation.

Tips for using External Vibrators for
concrete consolidation:
Proper placement of the external vibrators is critical
to ensure that the vibration is distributed over the
desired area of the concrete. Depending on the
concrete consistency, density of embedments and
the quality of the mounting, External Vibrators
produce an Area-of-Inuence determined by the
force and frequency of the vibrator and the duration
of the vibrating time.
The following guidelines for spacing External
Vibrators have been developed, but contractors
should determine specic spacing requirements
for each project to ensure complete coverage of
vibration and successful consolidation.

Vibrating times for external vibrators may be
longer than for immersed internal vibrators. Most
operators will initially vibrate for approximately
two minutes per lift, and increase or decrease
vibrating times as needed. Note that the same
criteria should be used to determine when the
consolidation is complete (no air bubbles at the top
surface, a thin lm of mortar on the top surface
and a stabilization of the speed of the vibrator).
Pour concrete into the forms in evenly dispersed
layers (lifts). Do not exceed a 20" lift height
otherwise the weight of the concrete can prevent
the entrapped air from escaping. Operate vibrators
in conjunction with each lift until the concrete is
fully consolidated. As each subsequent lift is placed,
locate additional vibrators for operation (or move
them from the previous level). Some operators
prefer to operate the previous lift’s vibrators for
a short period of time to promote “knitting” of the
two layers together.
Important!
If the thickness of the concrete to be consolidated
is greater than the area of inuence of the vibrator,
or if a higher-quality nished surface is required on
both sides, the contractor should locate alternate
vibrators on opposite form walls. For instance, the
rst vibrator is placed on the front wall and the
next is 5' (1.5 m) away but on the back wall. See
illustration below.
Alternating the vibrators on a concrete form
In some cases, when the thickness of the concrete
to be consolidated is extraordinarily large,
contractors may choose to use Internal Vibrators
in the center section, with External Vibrators used
simultaneously along the outer edges.
Forms should be well made to withstand the
strains of vibration.
1. If using wooden forms, use screws instead of
nails (which may back out with vibration).
2. Forms need to be well braced to prevent bulging.
3. Joints need to be closely t to prevent leaking.
4. Monitor forms during placement of concrete.
Tighten as needed.

Examples of Mounting External Vibrators
The vibrator is mounted directly to the form wall.
Without a channel iron, the force output is
concentrated where the vibrator is attached,
causing the wall to ex and may cause stress
cracks. The vibration is not evenly distributed
resulting in a poor concrete nish.
The vibrator is mounted on a channel iron, which
acts as the transducer of the energy. The vibration
is evenly distributed along the length of the channel
iron, which results in an excellent concrete nish.
Excellent Mount
Excellent Mount Do not weld the channel iron to horizontal
stiffeners. Cut out the channel to t over stiffeners.
Poor Mount = Poorly Finished Concrete Excellent Mount = Superior Finished Concrete

VII. Vibrator Orientation
Whenever possible, mount the vibrator with the
shaft in the horizontal position.
To ensure proper direction-of-rotation, the GCL
vibrators are assembled for either a hopper or a
concrete form application. This only applies to the
GCL due to the way it sits in its bracket. To reverse
direction of rotation, the shaft and side plates must
be removed and swapped, so that, the shaft air
inlet is on the opposite side of the housing. Always
observe vane and exhaust port orientation. See
page 7, Note 2).
The direction of rotation is determined by looking
at the side plate with the hose barb and exhaust
slots. The air enters the vibrator through the shaft
and pushes up the vane. (The vane is opposite the
keyway in the shaft.) The slots in the vane force
the air to one side only. The air carries the inner
roller with it as it travels around the shaft to get to
the exhaust slots. If the vane is facing the wrong
direction the air will have a direct path to the
exhaust without having to circle the shaft. If the
vane is not on the top of the shaft, but instead on
the side or bottom, the weight of the roller will not
press the vane back into the shaft and the vibrator
may not start.
