A HISTORY OF P&H MINING EQUIPMENT
Our beautiful Blue
Marble-Earth is home to nearly 7 billion people, our existence on this
remarkable planet perfectly positioned some 93 million miles from our sun with
a rate of spin nicely break by our nearby moon. Otherwise depends how well we
manage to get the things we need from our Earth’s crust. Food from agriculture,
wood for building materials, paper, and packaging, and minerals that provide us
with energy and the raw materials we need for our homes, roads, computers,
schools, transportation, communication and other vital systems. P&H Mining Equipment
designs, builds and supports a line of valuable tools that play an important
role in the global surface mining industry. Our products perform valuable roles
within the mining industry, they drill explosives containers into a hard
material such as copper in iron ore rock formations. Making possible effective
blasting for good fragmentation ease of loading and processing. They dig
material in copper in coal iron or oil sand gold and other mining operations and
soon they will helps crush and convey large volumes of material, thanks to new
in pit crushing conveying technology on
the horizon from P&H.
P&H Mining
Equipment began as a small machine and pattern shop of the first day of
December in 1884. It was a partnership between Chicago born industrial pattern
maker, Alonzo Pawling and German immigrant and machinist Henry Harnischfeger ,
although they were relatively young industrial artisans, Alonzo was 27 while
Henry was 29.
The machine and pattern shop partners were otherwise smart and steady manufacturing veterans in the bustling industrial town of Miwaukee, at first the little Pawling and Harnischfeger shop specialized in making parts and machines for major industrial firm in Old Miwaukee steam and engine poppet valves for example steamship steering gears and beer kegs sealing machines.
In 1887 Pawling
and Henry rebuilt a damaged bridge crane for the Edward P Allis manufacturing
company, they made the workings more rugged and easy to operate and mantain. Soon
after Pawling and Harnischfeger began building more such trains for railroad
repair shops and factories, suddenly Alonzo and Henry had a product of their
own and they began to expand their business to meet the growing demand for
bridge cranes. Around this time growing numbers of repeat customers began
referring to Pawling and Harnischfeger maker as simply P&H. They were
impressed with the exceptional quality and service, they obtained from the
small machine and pattern shop. Soon even Alonzo and Henry began referring to
their business as P&H. It was convenient and far easier to pronounce more
important the initials P&H had become symbolic of exceptional quality and service
value for industrial material handling equipment.
The year 1893 was
important for Pawling and Harnischfeger, when the Westinghouse Electric Company
bought their rival-the Gibbs Electric Company, Pawling and Harnischfeger were
able to acquire all of Gibbs machinery for making motors and controls, that
enabled P&H to began designing and building their own rugged line of AC and
DC motors and controls, matched to the demands placed upon their industrial
cranes customers. P&H insisted on the very best product design and
manufacturing process control, this was an important priority that would result
in even greater value for P&H customers going forward. 1893 was also pivotal
year because of a bank panic, that caused a man to fall for P&H cranes. Alonzo
and Henry realized their product line might be too narrow to sustain cash flow
and growth through the ups and downs of the business cycle.
They began to look
at digging machines as a path toward better balance at business growth, the
very first earth altering P&H machine was the P&H T1 Cuttertemper. It featured
a ram action pavement cutter and also a tamper plate for pressing loose materials back into place or pipeline installation
projects, among the first P&H earth-moving machines were trenches for
installing water pipelines, these were powerful and productive machines and they
were just the start of an effort that would continue to gain strength and
deliver great value for construction and mining operations.
In 1920 the firm rolled out a power shovel called a P&H
model 206. This was a gem of a digging machine, powered by the customer’s
choice of a Waukesha gasoline engine a Buda engine or a P&H electric motor.
The P&H 206 had a dipper capacity of just ½ cubic yard. Its payload was all
of 500 pounds, it was a rugged well-built easy to operate and easy to mantain
digging machine, demand for P&H 206 shovels soared as P&H established
the national and later a global distribution and service support network. By the
middle of the roaring 20's, P&H 206 shovels were being shipped to faraway
Bombay India. The P&H factory was humming with activity and the P&H
engineering was busy designing even more advanced digging and lifting machines.
P&H model 300
convertibles appeared in 1927, they featured a common lower works crawler
system, upon which the customer could choose from several options, including
Power Shovel, dragline, clamshell, piledriver, construction crane and skim
scoop. Pawling and Harnischfeger knew their ability to succeed required
applying only the very best people materials manufacturing methods and process
control.
P&H
machines were a riveted steel plate design until the early 1930's. That is when P&H
transformed the entire product line to an all welded design. Advantages were
clear compelling, all welded machines were lighter and tougher for greater
payloads, making possible far lower cost per tonne. Performance some of the
first welded P&H shovels went to work for Works Progress Administration
construction projects during the Great Depression years of the 1930's. It was
also during the 1930's that P&H began to apply WardLennard DC drive systems
to its shovels for faster digging and less fatigue for the shovel operator,
great strength and endurance and sore muscles and fatigue had been a normal
part of the job of the shovel or crane operator, as large levers needed to be
pushed and pulled to operate the
machine. Ward Lennard drive systems changed all that and made possible greater
tonnage per hour for the mine and construction site, with the outbreak of world
war II in 1939 the P&H factory slowly returned to full production once
again, following the difficult depression era decade. P&H employees
concentrated on building cranes and welding machines for industry and electric
shovels for the mining industry.
By 1942 the
factory was at full strength and shipping large volumes of equipment for the
war effort, P&H construction equipment helped build ports and runways and
battle damaged bridges during the conflict that ended in 1945, during the 1950's¸ P&H continued to
refine its shovels for greater productivity and reliability performance. In 1968,
P&H introduced what would become one of its finest ever electric mining
shovels, the P&H model 2800 mark. The first three P&H 2800 went to work for a metallurgical coal mine
in Western Canada, their durability and
productivity was such that they were still moving large volumes of material for
that mine. Over 20 years later, P&H began making crawler mounted drag lines
back in 1920 in fact P&H is believed to have introduced the first gas
engine power drag line, however credit for the first walking type dragline
belongs to John W page founder of the page engineering company based in Chicago
in 1903.
P&H in 1988 purchased the page engineering walking dragline product line to broaden its equipment solutions for the mining industry. P&H engineer and manufacturing specialist soon applied voice of customer inputs to developed an all-new 60 meter class P&H 90 20 walking dragline. Soon after the first 90 20 went into service of 1996 several more were deployed to coal mines in Australia in Canada, thanks to the exceptional productivity and ease of maintenance value they provide. In 1991 P&H acquired the drilling rig product line of gardner-denver to further increase the range of valuable cost reducing solutions from P&H for surface mining operations as they did with walking draglines, P&H engineers and manufacturing personnel began combining voice of customer suggestions with P&H know how to develop increasingly valuable drilling rigs for hard rock mining operations.
By the year 2009 and
the 125th anniversary of P&H mining equipment P&H 4100 class shovel
placements were fast closing in on the record placement of P&H 2800 class
shovels AC Drive and P&H 4100 C Boss and 4100 X PC shovels are now the next
generations loading tools of choice for high performance mining operations also
on the near horizon are the P&H in pit crushing conveying systems that can
provide many minds with an attractive alternative to truck based mature
handling at the heart of the P&H crush convey system is a mobile mining
crusher matched to a P&H shovel and designed for optimized production and
maintenance management.
