•
Stabilization of slopes, dams, dikes and levees.
•
Road construction for the compaction of base course concrete, marginal strip and sub-surface compaction jobs.
•
Road repairs of all types.
•
Building construction for the compaction of concrete and sub-soils in cellars and shed floors.
•
Garden construction and parks for the stabilization of roads and paths.
Description of function
The vibration required for compaction is produced by the ramming system, which is firmly attached to the ramming shoe.
The engine, which is flanged to the crankcase and is held in place by four screws, drives the ramming system over a
gear transmission and a connecting rod. The engine torque is transmitted by means of a centrifugal clutch.
The centrifugal clutch interrupts the flow of power to the ramming system at low engine speeds, thus allowing for a
perfect idling of the engine. The advance movement in forward direction of the rammer is ensured by means of the tilt
of the ramming system.
The engine can be switched off with the throttle control.
The drive engine works according to the diesel principle, and is started mechanically by means of a recoil starter. The
engine is air cooled and the air necessary for combustion is directed through a precleaner and a dry-type air filter.
The guide handle and frame are mounted on the ramming system with a set of shockmounts, therefore assuring a
minimum transmission of vibrations to the hands of the operator.
