Joy Global, Inc. engages in the manufacture and servicing of mining equipment for the extraction of coal and other minerals and ores. The Company’s equipment is used in major mining regions throughout the world to mine coal, copper, iron ore, oil sands and other minerals.
The Company sells original equipment to the mining industry. Its aftermarket market services include maintenance and repair services, mining equipment and electric motor rebuilds, equipment erection services and sale of replacement parts.
Segments
The Company operates in two business segments: Underground mining machinery (Joy Mining Machinery or ‘Joy’) and Surface mining equipment (P&H Mining Equipment or ‘P&H’).
Underground Mining Machinery
Joy is a manufacturer of underground mining equipment for the extraction of coal and other bedded minerals and offers service locations near major mining regions worldwide. It has significant facilities in Australia, South Africa, the United Kingdom, and the United States as well as sales offices and service facilities in China, India, Poland, and Russia. Joy products include: continuous miners; longwall shearers; powered roof supports; armored face conveyors; shuttle cars; Flexible conveyor trains; longwall mining systems (consisting of powered roof supports, an armored face conveyor and a longwall shearer); and roof bolters. Joy also maintains a network of service and replacement parts distribution centers to rebuild and service equipment and to sell replacement parts in support of its installed base. This network includes six service centers in the United States and eight outside of the United States, which are located in underground mining regions.
In July 2006, the company acquired Stamler mining equipment business. The addition of Stamler provided complementary products such as feeder breakers, continuous haulage systems and battery haulers to the Joy business.
Products and Services
Continuous miners: Electric, self-propelled continuous miners cut material using carbide-tipped bits on a horizontal rotating drum. Once cut, the material is gathered onto an internal conveyor and loaded into a haulage vehicle or continuous haulage system for transportation to the main mine belt.
Longwall shearers: A longwall shearer moves back and forth on an armored face conveyor parallel to the material face. Using carbide-tipped bits on cutting drums at each end, the shearer cuts material on each pass and loads the material onto the armored face conveyor for transport to the main mine belt.
Powered roof supports: Roof supports perform a jacking-like function that supports the mine roof during longwall mining. The supports advance with the longwall shearer, resulting in controlled roof falls behind the supports. A longwall face may range up to 400 meters in length.
Armored face conveyors: Armored face conveyors are used in longwall mining to transport material cut by the shearer away from the longwall face.
Shuttle cars: Shuttle cars, a type of haulage vehicle, are electric-powered with umbilical cable, rubber-tired vehicles used to transport material from continuous miners to the main mine belt where self-contained chain conveyors in the shuttle cars unload the material onto the belt. Some models of Joy shuttle cars carries up to 22 metric tons of coal.
Flexible conveyor trains (FCT): FCT’s are electric-powered, self-propelled conveyor systems that provide continuous haulage of material from a continuous miner to the main mine belt. The FCT uses a rubber belt similar to a standard fixed conveyor. The FCT’s conveyor belt operates independently from the track chain propulsion system, allowing the FCT to move and convey material simultaneously. Available in lengths of up to 570 feet, the FCT negotiates multiple 90-degree turns in an underground mine infrastructure.
Roof bolters: Roof bolters are roof drills used to bore holes in the mine roof and to insert long metal bolts into the holes to reinforce the mine roof.
Feeder breakers: Feeder breakers are a form of crusher that uses rotating drums with carbide-tipped bits to break down the size of the mined material for loading onto conveyor systems or feeding into processing facilities. Mined material is typically loaded into the Feeder Breaker by a shuttle car or battery hauler in underground applications and by haul trucks in surface applications.
Battery haulers: Battery haulers perform a similar function to shuttle cars. Shuttle cars are powered through cables and battery haulers are powered by portable rechargeable batteries.
Continuous haulage systems: The continuous haulage system provides a similar function as the FCT in that it transports material from the continuous miner to the main mine belts on a continuous basis versus the batch process used by shuttle cars and battery haulers.
Joy’s aftermarket infrastructure provides customers with parts, exchange components, repairs, rebuilds, whole machine exchanges and services.
Surface Mining Equipment
P&H is a producer of surface mining equipment for the extraction of ores and minerals and provides operational support for various types of equipment used in surface mining. P&H produces electric mining shovels, rotary blasthole drills and walking draglines for open-pit mining operations. P&H has facilities in Australia, Brazil, Canada, Chile, China, South Africa, and the United States, as well as sales offices in India, Mexico, Peru, Russia, the United Kingdom and Venezuela. P&H products are used in mining copper, coal, iron ore, oil sands, silver, gold, diamonds, phosphate, and other minerals and ores. P&H also provides a range of parts and services to mines through its P&H MinePro Services distribution group. In some markets, electric motor rebuilds and other selected products and services are also provided to the non-mining industrial segment. P&H also sells used electric mining shovels in some markets.
Products and Services
Electric mining shovels: Mining shovels are primarily used to load copper ore, coal, iron ore, other mineral-bearing materials and overburden into trucks or other conveyances. There are two basic types of mining loaders - electric shovels and hydraulic excavators. P&H manufactures electric mining shovels. Dippers (buckets) can range in size from 12 to 82 cubic yards.
Walking draglines: Draglines are primarily used to remove overburden to uncover coal or mineral deposits and then to replace the overburden as part of reclamation activities. P&H’s draglines weigh from 500 to 7,500 tons, with bucket sizes ranging from 30 to 160 cubic yards.
Blasthole drills: Surface mines require breakage or blasting of rock, overburden, or ore using explosives. A pattern of holes to contain the explosives is created by a blasthole drill. Blasthole drills manufactured by P&H bore holes ranging in size from 8 5/8 to 22 inches in diameter.
P&H MinePro Services provides life cycle management support, including equipment erections, relocations, inspections, service, repairs, rebuilds, upgrades, used equipment, new and used parts, enhancement kits and training. Under each life cycle management program, the Company provides aftermarket products and services to support the equipment during its operating life cycle.
The P&H Alliance Partner relationships include the following companies: AmeriCable Incorporated; Berkley Forge and Tool, Inc.; Bridon American Corporation; Carbone of America; General Electric Industrial Systems; Hensley Industries, Inc.; Hitachi Mining Division; Immersive Technologies Pty, Ltd.; LeTourneau, Inc.; Lincoln Industrial; MacWhyte; Phillippi-Hagenbach, Inc.; Prodinsa Wire Rope; Petro-Canada; Reedrill; Rimex Supply, Ltd.; Terex Materials Processing & Mining; and Wire Rope Industries, Ltd.
Customers
Joy and P&H sell their products primarily to global and regional surface and underground mining companies.
Sale of subsidiary
In November 2005, P&H sold The Horsburgh & Scott Co., a subsidiary that made industrial gears and mechanical gear drives for a range of industrial markets.
History
Joy Global, Inc. was founded in 1884.
