Definition of Tamping Rammer

The Mikasa MT-74F tamping rammer is a powerful compactingtool capable of applying a tremendous force in consecutiveimpacts to a soil surface. Its applications include soil compactingfor road, embankments and reservoirs as well as backfilling forgas pipelines, water pipelines and cable installation work.

The impact force of the MT-74F levels and uniformly compactsvoids between soil particles to increase dry density.

Circular motion is converted to create impact force. The MT-74Ftamping rammer develops a powerful compacting force at thefoot of the rammer. To maintain optimum performance, properoperation and service are essential.

Construction of Tamping Rammer

The Mikasa MT-74F is equipped with an air cooled, four-cyclegasoline engine. Transmission of the power takes place byincreasing the engine speed to engage the centrifugal clutch.

Rammer Gearbox and Spring Cylinder

The Mikasa MT-74F uses an oil bath lubrication system. Alwayscheck the oil level through the oil level sight glass at the rear ofthe tamper foot.

Controls

Before starting the MT-74F Tamping Rammer identify andunderstand the function of the controls. See Figure 1.
