Daewoo Heavy Industries & Machinery (DHIM) with a truly Oriental countenance, without losing dignity, overcame a prolonged economic stagnation that has befallen in the 1997 crisis, Southeast Asia, including Korea. In any case, the merger with Daewoo Doosan Group - not an act of desperation, like a failed unit cars Daewoo (now Chevrolet), and an informed, balanced step towards the active development of the company and further expansion into foreign markets, including Russia, where the vehicle DHIM good to see and find more and more supporters. In the first stage it will supply under the joint brand name Daewoo-Doosan with the prospect of changing to Doosan. To the credit of Korean businessmen, they are serious about Russia's market. Excavators, Wheel Loaders, Skid Steer supplied with the Belgian plant of the company, concrete pumps - from Korea. Moreover, access to the full range, without exception, in contrast to the practice of many corporations. Nomenclature of the European plant a few already, but you can easily order the vending model in Korea. In addition, the company has a policy of a single base configuration for all markets, without any "cuts" for the underdeveloped countries than sinning again, some manufacturers. Russia buyer gets everything that is listed in the description of the model, plus everything he wanted from the additional equipment. In regions with cold climates in the northern supply equipment performance, ie, not only with the pre-start flow-through heater and heater fuel, but with the replacement of standard rubber products, components for undercarriages made of cold-resistant materials, with appropriate technical oils and liquids, as well as heater cabin. Daewoo Engineering has been tested in the Khanty-Mansi Autonomous District, in the north of Krasnoyarsk Territory, in the Kemerovo and Tomsk regions. Family crawler excavator Daewoo Solar, which will be referred already noted half-century, and today the conveyor descends the fifth generation. As if to confirm the names of Solar ( «the Sun"), the company paints its machines in a bright orange color. The plant in Belgium produces four models weighing from 13 to 25 tons, including two with an elongated boom, and one specialist - to destroy the three-section work equipment, the lift cabin and additional hydraulics. Other models of excavators and loaders produces factory in Korea. Excavators are made in the "classic" layout: Full a full-platform, cross-mounted engine, radiators on the left side and pump compartment - on the right, X-shaped box section crawler truck with hydraulic drive rear drive wheels and the cab made by the forward support for the boom. For the entire model range used three straight six-cylinder diesel engine of its own production to meet the requirements of current environmental regulations EPA Tier 2 and EU Stage 2. Models of mass from 13 to 26 tonnes (Solar 140LC-V ... 255LC-V) equipped with a diesel DHI DB58TIS working volume of 5,785 liters of various designs intercooler. Depending on the model used cooling naduvochnogo air or liquid or air. On the other, more powerful and heavy models installed with air-cooled intercooler. At the 30-ton Solar 300LC-V and its modifications (with an extended boom and destruction) put diesel DE08TIS volume of 8.071 liters, the "senior" models (Solar 340LC-V ... 500LC-V) - DE12TIS volume of 11.051 liters. The engine, hydraulic system and controls are interconnected electronic e-EPOS (Electronic Power Optimizing System). The electronic "brain", located under the operator's seat, easily removed if you unscrew the four bolts. A very attractive feature of excavators Solar - complete preservation of functionality when you exit the electronics of the system, which, incidentally, in the practice of their operation in Russia has not happened. The excavator will continue to operate as before the era of computerization, although its performance and profitability will decline. In addition, the regulator of the engine speed is doubled with a cable release, set in the cockpit. Designers greatly simplify management by reducing the number of operating modes to two. In the fourth generation of them were three in the third generation - seven! Who could understand the difference between Levelling I mode and Levelling II mode, and most importantly, use them in real life? Now everything is simple and clear. There is a universal mode of digging and trenching mode, which is actively involved steering platform. And work out all the nuances of electronics. How it is implemented? If we take a hydraulic excavator scheme of the previous generation, then it is one pump feeds the motor of the right tracks, bucket cylinders and arrows, the second pump - the left caterpillar handle, steering, and an additional hydraulic line. In the fifth generation of increasingly complex. The division of functions between the pump is left (so if you refuse all electronics will continue to work), but the flow of hydraulic fluid from both pumps can be combined and sent to the executive body that is required at this time more power. Thus, the maximum engine power is used.
