INTRODUCTION
The Bartell tamping rammer is designed to give strong impact power despite its compact and
lightweight class. It is used to compress various types of soil. This machine serves as the front
line to pound loose soil to achieve the required compact density ratio for further construction
work.
DEFINITION
OF
TAMPING
RAMMER
A tamping rammer is a compaction machine that moves at a regulated frequency in a
predominantly vertical direction by an explosion pressure so as to produce a high impact force
to achieve high-density ratio of the compacted material.
STRUCTURE
This machine can be split into two distinct components, the upper body and lower body. The
upper component consists of the Power Source, Clutch, Connecting Rod, Operating Handle
and Fuel Tank that connects through the Shock Absorbing Rubber to the body. The bottom
component consists of Spring Cylinder (Sliding part), Foot and Bellows that covers the sliding
part.
POWER
TRANSMISSION
An air-cooled 4-stroke single cylinder gasoline engine is used as the power source for these
machines. The engine produces a rotary motion to the shaft that is copulated to the centrifugal
clutch.
The centrifugal clutch engages by running up the engine. Once it is engaged, power is
transmitted to the pinion, which in turn causes the gear to rotate. Henceforth, the reduction in
rpm is achieved. The gear is connected to a crankshaft, which converts the rotary motion into a
back and forth linear motion for the connecting rod. This action causes a compressive force to
the pairs of strong coil-springs between the ground and the connecting rod. Hence, the tamping
action begins. The weight of the machine and strong compressive spring force synergistically
produce powerful impact force at the foot.
APPLICATIONS
The tamping rammer is lightweight and small in size, yet able to deliver a strong impact force.
The machine’s usage can be categorized as the following:
A.
Construction
-
Compaction of backfill around foundation and forms
-
Compaction of sub-grades underneath footings
-
Base preparation for concrete work such as slabs, curbs and gutters.
B.
Utilities
-
Base preparation for pipelines
-
Compaction around and over pipelines
