The Suppressor Housing
The suppressor housing is located at the top of the machine. It is designed to absorb the vibration
generated from the vibrator gearbox. The suppressor housing consists of up to 12 rubber elastomers.
It is not required to operate with all 12 elastomers. The wick drain crew may remove pairs of elastomers
from both sides. Operating with a reduced amount of paired elastomers will allow the machine to run
smoother. Each elastomer delivers one ton of line pull for each inch of travel.
(
WARNING!
Hard
pulling for long periods of time will heat and damage the elastomers. The heat generated from
constant heavy line pull will destroy the chemical bond between the rubber and mounting
plate which will cause the elastomer to fail.)
When engaged in hard extracting, break every 15
minutes to allow elastomers to cool. Do not operate if

BOTTOMDRIVE
The suppressor housing mounts to the bottom of the leads with four pins located at
the top of the machine. The mandrel passes through the housing into the four
double sprockets and then through the center of the vibro. The outer suppressor
housing does not shake. The inner suppressor, along with the sprocket drive and
mandrel, will vibrate up and down if the vibro is turned on.
