CNCJ-72FW CNCJ-80K – GENERAL
INFORMATION
Definition of Tamping Rammer
The CNCJ-72FW CNCJ-80K 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 of force of the CNCJ-72FW CNCJ-80K levels and uniformly compacts voids
between soil particles to increase dry density.
Circular motion is converted to create impact force. The CNCJ-72FW CNCJ-80K 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 CNCJ-72FW CNCJ-80K 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 CNCJ-72FW CNCJ-80K 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 CNCJ-72FW CNCJ-80K Tamping Rammer identify and understand the
function of the controls. See Figure 1.
