The Automatic Soils Compactor is supplied with interchangeable rammer feet and has two stroke lengths which means that it can be used to carry out all normal compaction operations required in soil testing laboratories.

It is capable of both light and heavy compaction using either 101mm or 152mm diameter compaction moulds. The height of drop of the 2 inch (50.8mm) rammer can be set either at 12 inches (305mm) or 18 inches (457mm) as per requirements. The automatic compactor is provided with a standard rammer weighing 5.5lb for conducting light compaction and its weight can be increased to 10lb for heavy compaction test by attaching additional rods supplied. When using the 101mm diameter mould the rammer carriage is locked in one position and the total area of the mould is compacted in about 25 strokes. The Number of strokes can be programmed through the thumb wheel switches with digital display. A selector switch is provided on the control panel for selection between 101mm or 152mm diameter mould.

For 152mm diameter moulds the rammer carriage shifts radically by 25mm to give out 8 blows within the diameter of 101mm and 17 blows between 101mm and 152mm diameter. This sequence is repeated till the rammer completes 56 blows and the machine automatically stops.
