Auto Drop Hammers

The Geoprobe® Automatic Drop Hammer is an effective way to collect Standard Penetration Test (SPT) blow counts with a Geoprobe® machine. The Automatic Drop Hammer locks in position for easy transport, then easily unlocks and pivots into place for use...without the need to reposition the entire machine. The hammer can be used with hollow stem augers or 3.25 inch probe rods for even greater efficiency.

The Auto Drop Hammer is powered by the auxiliary hydraulics on the machine and is lifted into position using the probing cylinder. The 140-pound weight has a 30-inch free fall before making contact with the anvil. Safety was a prime consideration during the development of this unit, so all moving parts and impact surfaces are enclosed in a steel housing.
