adapter to welded design, but the firm also designed and manufactured its own line of electric arc welding machinery and welding rod products. Another technology advance applied to P&H digging machines during the 1930s was the Ward-Leonard DC electric motor drive system. Pawling & Harnischfeger began designing and making their own electric motors and controls starting in 1893 when they acquired assets of the Gibb Electric Company that were not needed when Gibb was purchased by Westinghouse Electric Manufacturing Company.

25,000-foot-pound-force (34,000 Nâ‹…m) of torque and large volumes of compressed air flowing at nearly 3,850 cubic feet (109 m) per minute create the tubes or "blast holes." The holes are loaded with explosives and then detonated. The blast produces a powerful shock wave that fragments the rock, making it easier to load, haul, crush and distill for its mineral contents.

The bucket lands atop the material and its teeth quickly bite into the material. Powerful drag force is applied to fill the bucket, followed by powerful hoist and swing forces applied to dump the material away from the excavation site to. P&H dragline bucket capacities range from 55 to 160 cubic yards (42 to 122 m).

tonnes and maximum capacities of 82 cubic yards / 62.7 cubic meters. Machine working weights would see similar dramatic changes. P&H Model 206 excavators originally had working weights of about 25 tons / 22.7 tonnes. P&H 4100XPC electric shovels today have working weights of about 1,645 tons / 1492 tonnes.

P&H Drilling Rigs are applied to boring grids of tubular explosives containers in hard-rock formations within mine operations. They apply three kinds of force to the task of advancing a tri-cone drill bit into rock. Bit-loading force up to 150,000 pounds-force (670,000 N) combines with up to

P&H Electric Mining Shovels are applied to loading haul trucks and in-pit crusher-conveyor systems in surface mine operations. They range in payload from 21 tons / 19.1 tonnes for the smallest model, the P&H 1900AL, to 120 tons / 108.9 tonnes for the model P&H 4100XPC. From March 2018 the

Over the ensuing decades, P&H earth moving machines evolved into larger, more powerful and more productive prime movers of material. By 1930, welding technology made possible the fabrication of lighter, stronger machinery versus traditional riveted-design machinery. P&H not only was an early

The rugged, reliable and productive quality of their products combined with the expertise available from Pawling and Harnischfeger were key factors in the ability of their manufacturing enterprise to endure economic recessions and continue growing into a modern, global business referred to by their

P&H Walking Draglines move large volumes of earthen overburden capping coal seams, and also overburden and phosphates. They wield a large-volume bucket that is cast out toward the material that needs to be relocated using a football field-length boom and powerful swing motors and transmissions.

Pawling was a castings pattern maker. Harnischfeger was a locksmith machinist with some engineering training. Both individuals served within the Whitehill Sewing Machine Company factory in Milwaukee starting in 1881. Concerned that Whitehill business operations were drifting toward failure, Pawling

exited the firm to start a small gear machining and pattern making shop in 1883. Needing more gear machining expertise and capital, Pawling persuaded Harnischfeger to join his firm as an equal partner. Their Pawling & Harnischfeger Machine and Pattern Shop officially began on December 1, 1884.

P&H excavators that started out in the 1920s with dipper and bucket payloads of about 500 pounds / 226 kilograms and dipper and bucket capacities of 0.5 cubic yard / 0.382 cubic meter would evolve into massive and powerful electric mining shovels with maximum dipper payloads of 120 tons / 109

In-pit Crushing-Conveying Systems (IPCCs) were introduced in 2008, which take earthen material excavated and deposited into a large holding hopper by an electric shovel, and then crush the material to an easy-to-convey size for transfer elsewhere in the mine. Soaring and volatile mine material
