Definition of Tamping Rammer
The Mikasa MT-86D tamping rammer is a powerful compacting
tool capable of applying a tremendous force in consecutive
impacts 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.
The impact force of the MT-86D levels and uniformly compacts
voids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MT-86D
tamping rammer develops a powerful compacting force at the
foot of the rammer. To maintain optimum performance, proper
operation and service are essential.
Construction of Tamping Rammer
The Mikasa MT-86D Tamping Rammer is equipped with an Robin
air cooled, four cycle gasoline engine. Transmission of the power
takes place by increasing the engine speed to engage the
centrifugal clutch.
Rammer Gearbox and Spring Cylinder
The Mikasa MT-86D uses an oil bath lubrication system. Always
check the oil level through the oil level sight glass at the rear of
the tamper foot.
Controls
