The electrically operated mechanical compaction process provided by the automatic soil compactors eliminates the need for tedious hand compaction methods, resulting in significant time savings. The device includes two rammers with different stroke lengths, making it suitable for conducting all normal compaction operations required in soil testing laboratories. The rammer possesses a circular face with a 50mm diameter that can easily be adjusted to 2.6kg or 4.9kg weight. Additionally, the drop is adjustable to either 310mm or 450mm. This apparatus is a reliable and efficient solution for soil compaction testing, providing accurate results in a timely manner.
