Rainhart Soil Compactor Tamping Heads

The Tamping Heads for the Rainhart 662EP Automatic Proctor Soil Compactor provide a versatile solution for laboratory soil compaction testing. Available in multiple configurations for 4" and 6" diameter molds, these interchangeable tamping heads allow laboratories to perform Standard Proctor, Modified Proctor, and specialized state DOT compaction procedures using a single compactor.

Designed for quick installation and convenient changeover, the tamping heads attach directly to the compactor's existing shaft without requiring additional shaft assemblies. Each 3lb tamping head can be combined with an optional 4.5lb supplemental weight to accommodate different testing requirements. This interchangeable design helps laboratories reduce equipment costs, simplify maintenance, and efficiently transition between testing methods.

Key Features

• Designed to perform soil moisture-density testing in accordance with ASTM D698, ASTM D1557, AASHTO T 99, and AASHTO T 180, and Tex-113-E, Tex-114-E & Tex-117-E
• Available in 4" circular face, 4" sector face, and 6" sector face configurations to accommodate different compaction mold sizes and testing methods.
• Each tamping head weighs 3lb and can be configured with an optional 4.5lb supplemental weight for testing procedures requiring additional hammer mass.
• Interchangeable tamping heads attach to a common compactor shaft, allowing quick transitions between testing methods without purchasing additional shaft assemblies.
• Screw-on installation simplifies tamping head replacement, equipment maintenance, and laboratory setup changes.
• Supports Texas DOT testing methods TEX-113-E, TEX-114-E, and TEX-117-E when the appropriate tamping head and supplemental weight combinations are selected.
• Provides a practical and cost-effective solution for laboratories performing multiple soil compaction procedures using one automatic compactor.

Included Items

Each purchase includes one selected tamping head or supplemental weight based on the product variant ordered. Available options include the 6" Sector Face Tamping Head (662-TMP-6S), 4" Circular Face Tamping Head (662-TMP-4C), 4" Sector Face Tamping Head (662-TMP-4S), and 4.5lb Supplemental Weight (662-TMP-SW). Tamping heads and supplemental weights are sold individually unless otherwise specified.

Lab Manager's Tip

Selecting the correct tamping head combination is essential for meeting the requirements of your laboratory's testing procedures. Rainhart identifies the following configurations for common ASTM, AASHTO, and Texas DOT methods:

When switching between Standard and Modified Proctor procedures, verify the complete hammer assembly mass, the appropriate 12" or 18" drop height, and the required number of blows per layer. Inspect the tamping head attachment periodically to ensure secure installation and consistent operation.
