Hammer Energy Output and Pile Bearing Chart
APE Model 6-2 Hydraulic Impact Hammer
The energy output is based on the identical Piston/Travel calculations utilized in the FHWA Gates Formula .
The pile bearing chart is based on the FHWA Gates Formula for pile bearing and is provided for the user's convenience only.
(800) 248-8498
Pile Bearing (tons) = ((1.75*SQRT "E" LOG10*10N)-100) /2
E = Developed Energy and N =Number of Blows Per Inch
