Manual Soil Compaction Hammers

Soil Compaction Hammers are sliding drop proctor hammers used for the Proctor Compaction of soil samples. Hammer masses are enclosed in guide sleeves with vent holes that ensure unrestricted free-fall.

The heavy knurled hexagonal cap is welded to the tube for a secure, comfortable grip during use and prevents rolling during storage.
