Definition of Tamping Rammer

The Mikasa MT-74FA 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-74FA levels and uniformly compacts

voids between soil particles to increase dry density.

Circular motion is converted to create impact force. The MT-74FA

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-74FA is equipped with an air-cooled, 4-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-74FA 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

Before starting the MT-74FA Tamping Rammer, identify and

understand the function of the controls. See Figure 2.
