The P&H Gearboxes reputation of being the sole line of drilling and transmission services for the industry since 1984 is based on their attention to detail and quality of build on their equipment. PandH was purchased by Komatsu In Japan and the entire design (not including the name) is being kept alive through Komatasu which is continuing to provide the same service and the same product lines under a different name.
PandH Machinery started with Alonzo Pawling and Henry Harnischfeger (P and H ) starting a manufacturing company out of Milwaukee Wisconsin. Coming from a pattern maker and a locksmith machinist the two supplied industry with machinery components and repaired said components allowing them to grow and expand into the transmission service industry.

The company began with electric mining shovels to load pit crushers and trucks following up with Drilling Rigs, Walking Draglines, And Pit Conveyor Systems P&H Gearboxes utilizing parallel shafts and epicyclic gearing they can push up to 450,000 ft-lbs of Torque.
