A Global Name In Mining; P&H Gearboxes

The P&H Gearbox Has had a reputation of being the sole line of drilling and material handling transmission services since the companies founding in 1984. National Gear Repair has Repaired P&H Gearboxes throughout the decades allowing us to become very familiar with their surface mining application throughout the minerals and mining industries. Though P&H Gearboxes are now produced through Komatsu Transmission From Japan, They’re industry leading innovation can still be seen with the new Komatsu Gearboxes which utilizes the same powertrain transmission, shafts, and clutch arms design allowing an almost interchangeability with the original P&H Gearboxes.

Why Use P&H Gearboxes

P&H Machinery started with industrial artisans Alonzo Pawling and Henry Harnischfeger (P and H) started a manufacturing business which would eventually evolve into P&H Mining Equipment in 1984 out of Milwaukee Wisconsin. Coming from a casting pattern maker and a locksmith machinist with light engineering training the two form the Pawling and Harnischfeger Machine and Pattern Shop. After supplying industries with machinery components and assembly for knitting machine manufacturers and brick makers eventually transforming the business to the manufacturing of cranes and eventually gearing for transmission and other moving machinery across America.

Since the creation of the Earth Moving Machines and excavators for the mining industry the P&H Mining Equipment Company began developing Electric Mining Shovels that load into trucks and in pit crushing conveyor systems, P&H Drilling Rigs to be applied to boring grids of tubular explosives for mining, P&H Walking Draglines and P&H In Pit Conveyor Systems. Every one of these pieces of machinery utilizes the P&H Standard Gearbox. P&H Gearboxes were designed to operate in the high temperature, high exposure settings of active mining industries. From the constant barrage of material through crushing conveyors or the shocks caused by explosives, the P&H Gearboxes are designed to not only survive under those circumstances but continue to operate at a high speed and efficient rate with little maintenance over the lifespan of the equipment compared to rival brands.

P&H Gearboxes including the new Komatsu Transmissions gearboxes are all designed to operate in extremely hazardous environments similar to the Lufkin Gearboxes. The same single, double or triple stage gearboxes operate within the same 300 kw to 3000 kw power rating and 3:1 to 100:11 Ratios. Similarly to P&H Gearboxes utilizing parallel shafts and epicyclic gearing they can push up to 450,000 ft-lbs of Torque. Understanding the application of Lufkin Gearboxes used in the mining industry as a direct competitor to P&H Gearboxes we can understand how these legacy boxes were designed by trying to work with what American standards were set to manufacturing.
