From the video that I saw yesterday, I want retell
about a history of P&H Mining Equipment.
So, enjoy it guys 😄 Happy reading. I hope you all
like it.
P&H mining equipment began as a small mechine and
pattern shop of the first day of December in 1884. It was a partnership between
Chicago born industrialpattern maker Alonzo Pauling and German immigrant and
machinist Henry Harnish voguer. 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 Milwaukee. At the first the little Pauling and Harnish
burger shop specialized in making parts and machines for major industrial firm
in Old Milwaukee steam engine poppet velves, for example steamship steering
gears and beer kegs sealing machines.
In 1887 Pauling and Harnish Hager rebuilt
a damaged bridge crane for the Edward P Allis manufacturing company. They made
the workings more rugged and easy to operate maintain soon after hauling and
Harnish began building more such trains for railroad repair shops and
factories. Suddenly Alonso and Hanry had a product of their own. 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 Pauling and Harnish
maker a simply P&H. They were impressed with the exceptional quality and
service. They obtained from the small machine and pattern shop. Soon even
Alonso and Henry began referring to their business as P&H. It was
convenient and far easier to pronounce more important. The initial P&H had
become symbolic of exceptional quality and service value for industrial
material handling equipment. The year 1893 was important for Pauling and
Harnish, when the Westinghouse Electric Company bought their rival the Gibbs
Electric Company, Pauling and Harnish voguer were able to acquire all of Gibbs
machinery for making motors and controls that enabled P&H to begin
designing and building their own rugged line of AC and DC motors and controls
matced to the demands placed upon their industrial cranes customers. P&H
insisted on the very best product design and manufacturing process control.
This was important priority that would result in even greater value for P&H
customers going forwarded.
1893 was also a pivotal year because of a bank
panic. That caused a man to fall for P&H cranes Alonso 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 path toward better balance and business groeth. The very first earth
altering P&H machines was the P&H T1 cutter tamper. It featured a ram
action pavement cutter and also a tamper plate for pressing loose material back
into place or pipeline installation projects. Among the first P&H earth
moving machines were trenchers for installing water pipelines. These were
powerful and productive machines and they were just the start of an effort that
would continue to again strength and deliver great value for contruction and
mining operations. In 1920 the firm rolled out a Power Shovel called P&H
model 206. This was a gem of a digging machine powered by the customers choice
of a Waukesha gasoline engine a Buda diesel engine or a P&H electric motor.
The P&H 206 had a dipper capacity of just ½ cubic yard. It is payload was
all of 500 pounds. It was a rugged well-built easy to operate and easy to
maintain digging mechine demand for P&H 206 shovels soared as P&H
estabilished the national and later a global distribution and service support
network by the middle of roaring 20s P&H 206 were being shipped to faraway Bombay
India. P&H factory was humming with activity and 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 option including Power
Sshovel dragline clamshell piledriver construction crane and skim scoop hauling
in Harnish Vaguer knew their ability to succeed required applying only the very
best people materials manufacturing methods and process control. You buy a
shovel or crane for one purpose and that is to handle materials at the lowest
possible cost. They declared in a product brochure in the final analysis the
purchase of a shovel or crane is unimportant but the cost every yard important.
They insisted P&H customers saw the logic and the great value in that position
their P&H shovels and crane performed far better than similar machines
built by other firms the value of the P&H brand was growing ever stronger
P&H machines were a riveted steel plate design until the early 1930s that
is when P&H transformed the entire product line to an all welded design
advantages were clear compelling all walded machines were lighter and tougher
for greater pay loads making possible far lower cost every tonne performance. Some
of the first all walded P&H shovels went to work for works progress
administration construction project during the great depression years of the
1930s it was alsoduring the 1930s that P&H began to apply Ward Lennard DC
drive systems to its shovels for faster digging and less fatigue for the shovel
operator great strength and endurance and sore mescles and fatigue had been a
normal part of the job of the shovel crane operator as large levers needed to
be pushed and pulled to operate the machine. Ward Lennard drive system changed
all that and made possible greater tonnage every hour for the mine and contruction
site with the outbreak of world war 2 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 crane and welding machines for industry and electric
shovel for the mining industry. By 1942 the factory was at full strength and
shipping large volumes of equipment for the war effort P&H contruction
equipment helped build port and runways and battle damaged bridges during the
conflict that ended in 1945. During the 1950s 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 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 belived to have introduced the first gas engine powered drag
line. However credit for the first walking type drag line belongs to John W
pages 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.
The P&H 320 X PC is the latest example of this process, it is one of the
standout drilling machines available today in iron ore copper and matallurgical
coal operations, also in 1991 P&H responded to the arrival a new generation
of high-capacity haul trucks by introducing the P&H 4100 X PC electric
shovel built P&H tough for the demanding mining operations the P&H 4100
also features time-saving maintenance friendly systems or lower cost 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.
