Heavy Equipment Caterpillar, Cummins, John Deere, Komatsu

For the past 80 years, Caterpillar Inc. (Caterpillar, Caterpillar) is developing a global infrastructure, and in collaboration with its global dealer network, is seeking a positive and sustainable results at all continents. Reaching in 2005 revenue by sales volume of $ 36.34 billion, Caterpillar is a leader in technology and the world's leading manufacturer of construction and mining equipment. The company Caterpillar Inc. (Caterpillar, Caterpillar) specializes in manufacturing of machinery and power plants for construction, agricultural and other activities.

The range of products includes hundreds of pieces of equipment, which is a leader in their field: dump trucks, graders, loaders, excavators, pipe layers, energetichesike system – this is an incomplete list of products Caterpillar. Company Cummins Inc. (Cummins, Cummins) – the world's leading development and production of diesel engines. History The company started in early last century, the U.S., where in 1919 he founded the firm Cummins inc. Dynamic development and efficiency of economic activity have turned it into a recognized leader in the production of diesel engines from 31 to 3500 hp, and brought up in the first place to produce motors from 50 hp and above. Production activities of Cummins Inc.

(Cummins, Cummins) is concentrated in three main areas: diesel engines for trucks and buses, ships, railway transport, agriculture, road construction and other industrial machinery, diesel generator sets, Components for Engines: filters, turbochargers, exhaust systems, etc Company John Deere (Deere) is the world leader in agricultural equipment, the largest manufacturer of construction and forestry equipment, and commercial technology for the care of parks and green areas with an annual turnover of more than $ 20 billion. John Deere (John Deere) produces engines for heavy equipment and financial services and related activities supporting the specialized areas business. Seven units of John Deere (John Deere) ensures the success of the enterprise at the global level: the production of agricultural equipment, manufacture of equipment for construction and forestry production of commercial equipment for the parks and lawns lending spare parts Motors Corporation today John Deere (Deere) is included in the list of the 100 largest industrial companies, published by the magazine 'Fortune', products are sold worldwide. However, it continues to expand its presence. John Deere factories located in Europe, Asia, North and South America. John Deere sells its products in more than 130 countries. Company Komatsu Ltd (Komatsu Komatsu) was founded in 1921 Meitaro Takeyuchi. Initially the company was a construction workshop. At the moment, Komatsu – the world's leading manufacturer of construction equipment. Celina Dubin: the source for more info. The main type of activities, brought brand recognition, Komatsu, is the production of construction equipment, machinery for mining, industrial equipment, which by its classification Komatsu attributes and storage loaders, as well as electronics. In addition, the zone of interests of the company fall into construction, real estate and shipping. As part of Komatsu Group includes Komatsu Ltd (Komatsu, Komatsu) and another 187 companies. 145 consolidated subsidiaries, 42 companies comprising the Group under the equity method. Together with Komatsu Ltd. Holding there were 188 companies.

Generator Device

37.3701 generator type – this three-phase alternator. It consists of a rectifier unit and the electronic voltage regulator. This generator is the right rotation (drive side), has a fan in the drive pulley and ventilation windows in the front part. The back cover of the generator is closed guard to prevent ingress of dirt. The generator based on the effect of electromagnetic induction. Alternating current generated by the fixed stator windings, which are the coils that are placed in the grooves of the magnetic (iron-pack). The rotor generates a magnetic flux.

He is also a coil (field winding), the transmitting direct current (excitation current). This coil is placed in the grooves of the magnetic circuit (pole system). The rotor consists of a shaft and slip rings. When the rotor rotates in front of the coils of the stator winding turns there are the "northern" and "south" pole of the rotor. Since changing the direction of the magnetic flux that penetrates the stator windings. Thus, there is an alternating voltage.

To convert AC to There are six permanent power semiconductor diodes that make up among themselves rectifier unit, which is installed in the housing of the generator. The field winding is fed from the generator and is connected through brushes and slip rings. After starting the engine power winding is carried out with total output of three additional diodes are installed on the rectifier assembly. The voltage of the electrical system controlled by an LED or a lamp on the instrument panel. If the fault in the generator are not available, after ignition the LED lamp or light up, and with the engine running – go out. Burning at the working engine warning light (LED) indicates that the generator fails, ie does not supply voltage or supply voltage below the battery voltage. Source: repairing generators, cars
