S-333 Automated Soil Compactor
This Automated Soil Compactor provides uniform, consistent and safe compaction. Quality results.
Applications
- Mechanical compaction of soil and soil-cement mixtures in the laboratory.
- Proctor, CBR and LBR samples

Benefits
- Soil layers are uniformly compacted, every time.
- Conformity to ASTM and AASHTO standards for hammer drop height is assured because the hammer lift compensates for changing sample height.
- Display shows number of layers and blow counts per layer to prevent common causes of operator errors. Blows can be pre-set in memory and automatically stop the machine.
- Drop heights and weights can be changed easily to accommodate alternate test requirements. 12 inch (std.) or 18 inch. Order separately.
- Changing hammer drop height is simple and very quick — just insert a couple of spacers and you’re ready.
- Rotating base accepts molds from a variety of manufacturers.
- Works with standard, CBR and LBR molds.
- Safety operation — fully enclosed drive mechanism, locking mechanism to prevent the hammer from falling when the machine if OFF, and emergency shut-off button.
