Joy Global
Encyclopedia
Joy Global Inc. is a Fortune 1000
company with an integral role in the mining industry. It manufactures and services heavy machinery used in underground and surface mining. Its underground mining machinery business operates primarily through subsidiary Joy Mining Machinery
, a brand known for its longwall mining products and systems. while the other division, P&H Mining
Equipment provides a complementary role as a surface mining
equipment manufacturer and servicer, largely in the business of large excavating and drilling machines. The company also deals in aftermarket parts
.
The present company has its roots in two separate but related businesses that came together in 1994, when Harnischfeger Industries, Inc. bought Joy Technologies Inc. for 700 million dollars. Joy Global Inc. was known as Harnischfeger Industries until 2001 when it emerged from bankruptcy and was renamed. Its emergence from bankruptcy was a success profiting $
744 million in the next six years.
With respect to P&H Mining Equipment, the company markets four product lines and its equipment is used in 90 % of the world's surface mines. 90 % of the parent company's manufacturing business comes from coal mining, a business Joy Global does well in as the leading manufacturer of underground mining equipment.
in the Great Lakes region of the United States
. A thriving center of industrial machinery manufacturing at the convergence of three rivers entering Lake Michigan, Milwaukee had been a small fur trading post 50 years earlier before transitioning to a community built upon wheat distribution, beer brewing and iron milling. In fact, the Joy Global Inc. headquarters is sited upon one of the original trading posts in Milwaukee established in the 1820s by French voyageur Solomon Juneau.
Among the growing number of machinery manufacturing firms in Milwaukee in the 1870s was a struggling firm known as the Whitehill Sewing Machine Company. Alonzo Pawling and Henry Harnischfeger managed castings patternmaking and gear machining operations within the Whitehill factory. Concerned that Whitehill lacked the marketing and manufacturing discipline needed to grow, they formed a machine and pattern shop on December 1, 1884 .to manufacture, assemble and service components and equipment needed by other, larger manufacturing firms in the region.
In 1887, Pawling and Harnischfeger helped rebuild and upgrade an overhead bridge crane within the foundry operations of the Edward P. Allis Manufacturing Company that collapsed following an attempt to move a load beyond its rated lifting capacity. The rebuilt crane featured a simplified system of motors and gearboxes to drive the bridge, trolley and hoist functions on the lifting machine, replacing a complex system of ropes and pulleys that failed on the earlier version. Soon after, Pawling and Harnischfeger began building their own line of overhead cranes for manufacturing and warehouse
operations.
A bank panic in 1893 caused demand to fall for the cranes designed and built by Pawling and Harnischfeger who by that time were being referred to by their customers as simply “P&H”. The partners decided to expand their product line to include earthmoving machines in order to increase the ability of their business to withstand the next economic downturn. It was also in 1893 that P&H acquired the motors and controls manufacturing assets of the Gibb Electric Company following the acquisition of Gibb by Westinghouse Electric
Manufacturing Company, as Pawling and Harnischfeger wanted greater control over the application of motors applied to their crane line.
Meanwhile in Cumberland, Maryland
, 12-year-old Joseph Francis Joy
went to work as a slate picker in a coal mine, eventually working underground with picks, hand-held drilling augurs and shovels to load coal into rail-mounted cars. By 1903, 20-year-old Joe Joy was learning mechanical engineering
via a mail-order course and tinkering with ideas for mechanizing the coal-mining process. Joy’s designs attracted no interest from underground coal mines at first, but the Pittsburgh Coal Company in 1916 saw the potential productivity gains that might be obtained by investing in a Joy gathering-arm type loader. Joy earned a U.S. patent on his device in 1919 and launched a business that would become Joy Mining Machinery that same year.
Back in Milwaukee, the Pawling & Harnischfeger business had become known as Harnischfeger Corporation following the death of Alonzo Pawling in 1911. By the mid 1920s, the firm had become a large and growing supplier of crawler-mounted shovels and cranes applied to construction
and mining operations – all bearing the familiar “P&H” trademark that had become synonymous with exceptional quality and service value established by Pawling & Harnischfeger. Over the ensuing decades, P&H-trademark shovels and cranes would grow in size, capacity and drives and controls technology. The firm expanded its product line with the onset of the Great Depression
, adding welding
machinery, diesel engines and prefabricated homes to its P&H line of shovels and cranes.
By the 1960s and 70s however, the firm had divested its welding, diesel engines and prefabricated homes businesses in order to concentrate on its strongest product lines that included construction and mining machines as well as overhead cranes, hoists and material handing systems. Recessions in the 1970s and 80s led the firm to shift its strategic focus to include pulp
and papermaking machinery and systems as well as computer systems applied to military and aerospace systems.
What had begun as the Pawling & Harnischfeger Machine and Pattern Shop in 1884 would evolve in 1983 into a conglomerate corporation known as Harnischfeger Industries, Inc. Harnischfeger Industries acquired a pulp and papermaking firm known as the Beloit Corporation in 1986, followed by acquisition of Washington DC-based computer systems supplier Syscon Corporation later that same year. In 1995, the firm acquired Joy Mining Machinery
, by then a leading supplier of underground mining equipment based in Franklin, Pennsylvania founded in 1919 by Joseph Francis Joy.
Harnischfeger Industries divested the P&H overhead cranes and hoist business in 1997. That business continues with P&H-trademark cranes
and hoists supplied and supported by Morris Material Handling Inc. based in Oak Creek, Wisconsin USA. Morris Material Handling was acquired as of December 31, 2009 by Konecranes, Inc., a Finland-based supplier of cranes and service support for industrial applications worldwide.
Also in 1997, a currency devaluation crisis in Southeast Asia (1997 Asian Financial Crisis) led to the collapse of a major paper manufacturing business based in Indonesia and the subsequent default on numerous contracts valued in excess of US$5.25 billion for equipment and infrastructure systems ordered for a major capacity expansion. One of those contracts valued in excess of US$250 million was held by Harnischfeger Industries’ Beloit Corporation subsidiary. Harnischfeger Industries entered Chapter 11 U.S. Bankruptcy Code. protection and restructuring following the Beloit Corporation collapse in the wake of the Southeast Asian currency crisis.
Joy Global Inc. became the direct successor to Harnischfeger Industries, Inc. upon emergence from the Chapter 11 financial restructuring process on July 12, 2001. Joy Global would go forward as a supplier of equipment and life cycle management service support solutions for the global mining industry through its subsidiaries P&H Mining Equipment concentrating on surface mining operations and Joy Mining Machinery
focusing on underground mining operations.

Joy products include:
- Continuous miners – electric, self-propelled digging machines that cut material using carbide-tipped bits on a horizontal rotating drum. Once cut, the material such as coal is gathered onto an internal conveyor and loaded into a haulage vehicle or continuous haulage system for transportation to the main coal load-out conveyor belt.
- Longwall shearers – a material-cutting machine that moves back and forth on an armored face conveyor running parallel to the coal or other material being mined. Using carbide-tipped bits on cutting drums at each end, the shearer cuts a 1.2-meter to 6.5-meter swath of material on each pass of longwall miningLongwall miningLongwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice .

and simultaneously loads the material onto the armored face conveyor for transport to the main material load-out conveyor belt.
- Powered roof supports – to provide an open work space shielded against mine roof collapse, roof supports use powerful hydraulic cylinders to elevate and hold strong, thick steel plates in a horizontal position to protect the longwall shearer and armored face conveyor. The supports advance with the longwall shearer and armored face conveyor units, resulting in controlled roof falls behind the supports. A longwall face may range up to 400 meters in length.
- Armored face conveyors – material handling conveyors that transport material cut by the shearer away from the longwall face.
- Shuttle cars – low-profile, electric-powered, rubber-tire material haulage vehicles that transport up to 22 metric tons of coal and other material from continuous miners to the main mine run-out conveyor belt, discharging their material loads with the help of on-board chain conveyors.
- Flexible conveyor trains – electric-powered, self-propelled conveyor systems available in lengths up to 570 feet / 174 meters and capable of being configured into multiple 90-degree turns to help move material out of an underground mine operation.
- Roof bolters – drilling rigs that bore holes into an underground mine roof, making possible the insertion of long metal bolts to help reinforce the mine roof.
- Battery haulers – battery-powered material haulage cars similar to shuttle cars.
- Continuous haulage systems – unlike the pulsed, batch load throughput made possible by usage of shuttle cars and battery haulers, continuous haulage systems feature a connected series of bridge structures that utilize chain conveyors to obtain continuous throughput of material from the mine face to the main mine load-out conveyor belts.

- Electric mining shovels – with working weights in excess of 1,645 tons / 1,492 metric tons and powered by large, high-efficiency electric motors linked to planetary and case-type transmissions, P&H electric bring powerful hoist, crowd, swing and propel forces to the task of moving up to 120 tons / 109 metric tons of material every 30 seconds from the mine face into the waiting tray of a nearby haul truck or in-pit crushing-conveying system hopper. P&H shovel dippers range in size from 12 cubic yards / 9 cubic meters up to 82 cubic yards / 63 cubic meters.
- Blast hole drilling rigs – hard rock formations are typically found within surface mining operations and they must undergo drilling and blasting in order to fragment the rock for easier digging, crushing and refining processes within the mine operation. P&H blast hole drilling rigs apply either electricity or diesel power to obtain three forces needed to advance a tri-cone drill bit into hard rock: “pulldown” or downward bit-loading force, high-torque rotary force, and large volumes of “bailing air” needed to cool the tri-cone bit and evacuate or push rock chips, particles and dust toward the top of the tubular blast hole. When a grid of blast holes has been drilled, each hole is loaded with explosives and then carefully detonated in order to shatter and fragment the rock formation with a high-energy shock wave. Drills typically work ahead of advancing shovel-truck fleets in surface mine operations.

Perched on large, flat, cylindrical steel “tubs” and equipped with football field-length booms and buckets large enough to hold several sport utility vehicles, walking draglines use hoist, swing and drag forces to cast their buckets out to the next targeted area from which earth needs to be gathered up and moved. They then apply inward “drag” force to quickly load the bucket, and then hoist and swing forces to cast-dump the material onto a nearby spoil pile. Draglines are used primarily to strip large volumes of overburden away from thick seams of coal. They are also a prime mover in phosphate mining operations.
In-pit crushing-conveying systems – as surface mines become deeper and wider over many years of operations, the costs associated with using haul trucks to move material can escalate to inflict rising cost pressures on mine cost structures. To provide surface mines with a cost-reducing material handling alternative to haul truck-based operations, P&H is developing in-pit crushing-conveying systems that enable shovels to load a mobile mining crusher with material.
