MVH-120GH — GENERAL INFORMATION
Definition of Plate Compactor
The Mikasa MVH-120GH is a walk-behind, reversible plate
compactor design for the compaction of sand, clay 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 soil 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 MVH-120GH produce low amplitude
high frequency vibrations, designed to compact granular soils.
The resulting vibrations cause forward motion. The engine and
handle are vibration-isolated from the vibrating plate. The heavier
the plate, the more compaction force it generates.
Reversible Vibratory Plates
Reversible vibratory plates have two eccentric weights that allow
a smooth transition for forward and reverse travel, plus increased
compaction force as the result of dual weights.
Due to their weight and force, reversible plates are ideal for
semi-cohesive soils.
Frequency/Speed
The compactor's vibrating plate has a frequency range between
2500 to 6000 vpm (vibrations per minute). The forward and
reverse travel speed of the compactor is approximately
75 feet/minute (23 meters/minute).
Engine
The Mikasa MVH-120GH Plate Compactor is equipped with a
Honda air-cooled, 4-cycle, gasoline engine.
Controls
Before starting the MVH-120GH Plate Compactor, identify and
understand the function of the controls and components as
indicated in Figure 1.
