2. Applications, Warnings,
Structure and Power Transmission
Applications
Plate compactor is the machine that compacts the ground and it intends to make the surface smooth, by transmitting vibration through vibrating plate, which power generated from single rotor in vibrator case.
This machine is suitable for making the ground surface smooth, such as leveling the soil and beaching, finishing
the asphalt paving.
Warning about incorrect applications and techniques
This machine is hard to move forward on a soil with much water (especially clay soil). It is not suitable for such
application. This machine is difficult to level a ground include big stones due to insufficient compacting force. Plate
compactor is mainly applied for compacting surface smooth and it is not effective for jobs that requires heavy
compaction. In case of compacting ground deeply into lower layer, it is recommended to use Tamping Rammer,
Vibro Compactor or Vibration Roller of which compacting force is rather effective. Please use this compactor for
compacting surface on soil, sediment, beaching and asphalt. It is not recommended for use this machine for the
other applications.
Structure
The upper part is made up of Power source, Handle, Belt Cover, Water Tank for sprinkling and Guard Hook which
are fixed by Engine Base. The Engine base is fixed on Vibrating Plate by Shock Absorbing Rubber. The lower part
is made up of Vibrating Plate and Vibrator Unit that has an Eccentric rotary shaft built in. The power source is
transmitted from the centrifugal clutch on engine output shaft to the Eccentric rotary shaft through V-belt.
Power transmission
Air-cooled Single Cylinder Engine is amounted as power source and Centrifugal Clutch is fixed on engine output
shaft.
Centrifugal Clutch engages by running up the engine and engine R.P.M. is reduced to suitable number for
compacting. The rotation of engine is transmitted from V-pulley integrated with Clutch Drum to Vibrator Pulley
through V-belt.
Vibrator Pulley rotates Eccentric Rotor Shaft that is contained in Vibrator Case. The generated vibration created
from Eccentric Rotor is transmitted to Vibrating Plate.
Vibration of Vibrating Plate carries the machine forward; the vibration with the weight of the machine makes the
compaction of the ground possible.
