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
fits 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 flow 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, filter, and lubricator.
•
Always disconnect air line before maintenance.
