Ploog Mechanical Soil Compactor

The Ploog Mechanical Soil Compactor automates Standard and Modified Proctor specimen preparation by controlling hammer blows, rotating the mold after each blow, and stopping automatically when the preset blow count is reached. The system accommodates both 5.5lb and 10lb compaction configurations and compensates hammer lift as specimen height increases during compaction, providing consistent and repeatable soil specimen preparation.

Key Features

• Meets ASTM D558, D559, D560, D698 and D1557 requirements
• Supports AASHTO T 99, T 134, T 135 and T 180
• Automatic mold rotation after each blow
• Programmable electronic blow counter
• Automatically stops at completion of selected blow count
• Supports 5.5lb hammer with 12" drop
• Supports 10lb hammer with 18" drop
• Hammer lift compensates for changing soil height
• Front-access hammer changes simplify maintenance
• Start/stop function operates independently of counter

Included Items

• Ploog Mechanical Soil Compactor

• One 4" compaction mold
• One 6" compaction mold

Typical Applications

Standard Proctor testing, Modified Proctor testing, moisture-density relationships, soil-cement specimen preparation, CBR-related preparation, DOT soils laboratories, geotechnical testing, and earthwork QC/QA.

Lab Manager's Tip

One of the strongest features of the Ploog package is how complete it is out of the box. With both 4" and 6" molds and the hardware needed to configure Standard and Modified compaction, the lab does not need to build the basic Proctor setup one accessory at a time.
