CME Automatic SPT Hammer

The CME 140-lb automatic SPT hammer provides extremely consistent and accurate Standard Penetration Test results, meeting all ASTM-D-1586-99 requirements. There are no ropes or cables to impede the free-fall of the weight, and a viewing slot allows you to verify the 30 inch fall height. And for safety, all moving parts are enclosed, including the impact area between weight and anvil.

The hammer easily swings on a hydraulic cylinder from its stored position to on-hole position. The same cylinder is also used to raise and lower the hammer. And since raising and lowering is done hydraulically, set-up is quick and almost effortless.

In addition to the standard 140 pound system, CME hammers are available with 340-lb, 300-lb, 170-lb and 110-lb weights. A low clearance model is also available on CME-55LC rigs for use in limited overhead situations.
