GENERAL INFORMATION
DEFINITION OF TAMPING RAMMER
The Multiquip MTX70HF 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 MTX70HF levels and uniformly
compacts voids between soil particles to increase dry
density.
Circular motion is converted to create impact force.
The MTX70HF 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 MTX70HF is equipped with an 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 MTX70HF uses an oil bath lubrication system. Always
check the oil level through the oil level sight glass at the
rear of the tamper foot.
