MVC-77 SERIES — GENERAL INFORMATION
Definition of Plate Compactor
The Mikasa MVC-77 Series is a walk behind, plate compactor
designed for the compaction of sand, mixed soils and asphalt.
This plate compactor is a powerful compacting tool capable of
applying a tremendous force in consecutive high frequency
vibrations to a soil surface. Its applications include compacting
for road, embankments and reservoirs as well as backfilling for
gas pipelines, water pipelines and cable installation work.
Vibratory Plates
The vibratory plates of the compactor produce low amplitude
high frequency vibrations, designed to compact granular soils
and asphalt.
The resulting vibrations cause forward motion.The engine and
handle are vibration isolated from the vibrating plate.
Frequency/Speed
The compactor's vibrating plate has a frequency range between
5,800 vpm (vibrations per minute).The forward and reverse travel
speed of the compactor is approximately 23 meters/minute (75
ft./minute).
Engine
The Mikasa MVC-77 Series Plate Compactor is equipped with
either a Honda or Robin air cooled, 4-cycle gasoline engine.
The engine drives an eccentric weight at a high speed to develop
a compaction force.

7. Compactor traveling speed may drop on soils which contain
clay, however there may be cases where traveling speed
drops because the compaction plate does not leave the
ground surface easily due to the composition of the soil.To
rectify this problem do the following:
z Check the bottom plate to see if clay or
equivalent material has been lodge in the
plate mechanism. If so, wash with water and
remove.
z Remember the compactor does not work as
efficiently on clay or soils that have a high
moisture content level.
z If the soil has a high moisture level, dry soil
to appropriate moisture content level or carry
out compaction twice.
