The Corporation Case-New Holland (CNH), three model series graders under the brand names Case, FIAT-Kobelco and O & K. Product Range Case Construction Equipment - the three basic models of medium and heavy graders 845, 865, 885. Y FIAT-Kobelco three medium and heavy grader G140, G170, G200, as well as an easy grader and G110-wheel-drive version of its G110 6WD. At O & K Orenstein & Koppel AG, three basic models F106.6, F156.6, and F206, each of which has four-wheel drive version. The structure of the model number depends on the characteristics of the market, on which he focuses. Thus, the range of Case consists of medium and heavy vehicles, as is intended primarily for markets in North America. In the ranks of the FIAT-Kobelco and O & K presented and light machines, because their main customers - the countries of Europe. Medium and heavy machine Case and FIAT-Kobelco the characteristics are almost identical, differing only in weight, engine parameters, and greydernogo equipment. , For example, Case completed with Cummins diesel engine working volume of 5.9 liters, FIAT-Kobelco - New Holland 7,5 liters. Both engines are close to the parameters and meet the requirements of European and U.S. environmental standards. In heavy machine Case 885 and FIAT-Kobelco G200 installed diesel Cummins 8,3 L, with a capacity of 155 kW turbo. Medium and heavy graders Case and FIAT-Kobelco equip transmission with eight forward gears and four - reverse. Slow down for very precise planning, you can use special pedals (inching pedal). The maximum angle of fracture frame ± 25 °. Minimum turning radius with fracture of the frame, tilting front wheels with a differential unlocked 7 305 mm. Turntable Blade rotates 360 °. Additional equipment: front and rear mnogozubye rippers, blade, front buffer plate, and a necessary counterweight to their operation Hydraulic. In the model number of FIAT-Kobelco allocated an easy grader G110 and G110 6WD-wheel-drive version with a 5.9-liter 6-cylinder Cummins diesel engine with turbo, hydromechanical manual powershift with six forward gears and three - going backwards. Front wheel drive version with G110 6WD consists of a variable displacement pump performance, built-in wheel motors and electronic control system. The microprocessor synchronizes the rotational speed of the front wheels and wheel balancing carts. The frame is broken by two hydraulic cylinders at an angle of ± 28 °, the minimum turning radius is 6 500 mm. Traction frame, as a heavier car, A-shaped. The turntable rotates through 360 °. Greyderny blade can be raised to 117 ° right and left at 76 °. In more severe models of blade left and right rises to 90 °. G110 additionally completed greydernym blade length of 3 050 mm, Blade jib, counterweight, three types of rippers, etc. Easy Grader O & K F106.6 and his version F106.6A design have much in common with the FIAT-Kobelco G110. Their equip 6-liter turbocharged diesel engine manufacturing corporation CNH, hydromechanical manual powershift (6 forward gears and 3 - reverse). Blade can be installed vertically on the right-left at 90 °. I mean graders O & K F156.6 and F156.6A the same as in F106.6, modern design, but they are more powerful at 27 kW. Heavy machinery F206 and F206A significantly different from other corporations graders CNH. They installed diesel Deutz 6,1 liter air-cooled power of 134 kW, hydromechanical manual powershift (6 forward gears and 3 - reverse). Greyderny blade can be raised right on the corner to 100 ° and the left - up to 112 °. Rama "breaks" at an angle of ± 28 °, the minimum turning radius at the maximum "fracture" of the frame 7 700 mm. O & K offers a different optional equipment: Front and rear mnogozubye rippers, ripper, fitted instead greydernogo Blade, blade, greydernye dumps with width 3 360, 3 965 and 4 270 mm, right (610 mm) extension of blade, special devices for Blade, with which you can prepare, for example, a narrow trench under the foundation or curb, drainage ditch on the slope. Komatsu Corporation develops two model series graders under the trademarks Komatsu and Galion. In the model range averages graders Komatsu - GD555-3, GD655-3 and GD675-3, to modify them with engines certified by EPA Tier 2, heavy graders - GD-750A-1 and GD825A-2. Grader GD825A-2 - only in this review, whose cabin rises to 710 mm. Most cars are equip with 6-cylinder diesel turbocharged Komatsu capacity from 104 to 209 kW. At GD-750A-1 is 6-cylinder diesel Cummins 10,8 l, 168 kW. Especially for graders Komatsu (except GD825A-2) to develop hydro manual powershift with torque converter and a locking friction clutch (8 forward gears, 4 - reverse). CP operates in two modes: with lock and unlock the converter. In carrying out planning works on the 1 st to 4 th gears back and forth the operator unlocks the torque converter. In this mode, the wheel passed the maximum torque, and engine and transmission are protected from overloads. When moving to a higher gear torque converter automatically blocked. If you remove snow using 5-7-S transmission, 8-I - transport. Mode locking torque converter is available in all gears. In all modes of operation pedal very precise movements (inching pedal). For the most severe model GD825A-2 full weight 26 420 kg developed hydro-mechanical planetary 8-speed gearbox is fully reversible HYDROSHIFT. Maximum speed GD825A-2 forward 44,9 km / h, back - 47,9 km / h. For Komatsu graders may be found only on balancing the cart, the location of junction of the frame behind the cab, low profile front of the cap beam. Maximum angle of elevation Blade 90 ° right-left. The model number of secondary graders Galion - the three basic models 830, 850 and 870 series B and C, and each model has a four-wheel drive version. Power 6-cylinder diesel Komatsu, installed them, from 107 to 152 kW. KP - 6-speed hydro. Îïöčîííûé-wheel drive is provided by a variable pump performance. In the front wheels are mounted motors. The speed of rotation of the front wheels and wheel balancing carts synchronized electronic system.
