This chart is based on the FHWA-modified version of the Gates Formula for pile bear ing and is provided as a convenience only for those applications where this

formula is specified. ICE® has no prefer ence for this particular formula over any other. Where:

(ram weight × stroke) if lower fuel setting N = Blow count per 1”

CAUTION: Driving at ten blows per inch is considered practical refusal. Driving in

excess of ten blows per inch for more than six inches of driving or driving in excess

of 20 blows per inch at all is considered improper use and will void the hammer warranty.

NOTE: The FHWA recommends using a factor for safety of 3.5 with the Gates formula.
