4-inch Sector Face Tamping Head
The Rainhart 662-TMP-4S is a 4-inch sector face tamping head designed exclusively for use with the Rainhart 662EP Proctor Soil Compactor. As part of a versatile system, Rainhart tamping heads provide a simple and reliable solution for performing a wide range of soil compaction tests. This specific head is required for conducting tests compliant with TEX-114E and TEX-117E standards.
The Rainhart Proctor Soil Compactor System
Recognized as one of the most advanced and versatile soil compactors in the industry, the Rainhart 662EP is engineered for high-volume labs that demand efficiency, accuracy, and low maintenance.
Unlike conventional compactors where the mold rotates, the Rainhart system features a revolving tamping head that moves around a stationary specimen. This signature circular pattern automatically adjusts to the specimen's height, delivering precise blows and eliminating the need for manual adjustments between layers. This innovative design leads to more accurate, repeatable results and significantly shorter cycle times.
All Rainhart tamping heads are fully interchangeable and attach to a single shaft, removing the need for costly additional components when switching between test types.
Key Features & Benefits:
- Versatile Compatibility: The 662EP compactor system meets numerous standards, including ASTM D698 & D1557, AASHTO T99 & T180, and accommodates various state-specific methods like TxDOT TEX-113E, TEX-114E, TEX-117E, and FLDOT FM 5-515.
- Fully Automatic Operation: A user-friendly programmable counter allows for simple "set it and forget it" operation. Just load the mold, start the counter, and the machine automatically stops after imparting the desired number of blows.
- Rapid Changeovers: Effortlessly switch between Standard and Modified Proctor testing (12" to 18" drops) or swap out tamping heads with the simple screw-on design.
- Simplified Maintenance: Designed for easy repair, every part on the compactor can be replaced using common hand tools, minimizing downtime.
- SCA Compatible: The Rainhart Proctor is the only soil compactor compatible with the Soil Compaction Analyzer (SCA) for advanced data collection and analysis.
- Comprehensive Accessories: A full suite of accessories, including various tamping heads, molds, perforated base plates, and finishing tools, is available to meet all your soil compaction testing needs.
