4in Circular Face Tamping Head for Proctor Soil Compactor

The Rainhart 662-TMP-4C is a 4-inch circular face tamping head specifically designed for use with the Rainhart 662EP Proctor Soil Compactor. Rainhart's interchangeable tamping heads offer a versatile, durable, and user-friendly solution for conducting a wide array of soil compaction tests in high-volume laboratory environments.

The Rainhart 662EP Proctor Soil Compactor sets the industry standard for versatility and advanced engineering. Designed for high efficiency and low maintenance, it features a unique circular compaction pattern. The tamping head rotates around the stationary sample, rather than the sample revolving on a turntable. This innovative design ensures blows are delivered uniformly across the specimen surface, leading to more accurate, repeatable results and significantly shorter cycle times. All Rainhart tamping heads are interchangeable using a single shaft, which simplifies setup and eliminates the need for extra costly components.
