Kamaz Engine

Kamaz Engine

Body type of 'box', too, became a standard and has been used to 'combat' technicals until 1998. For the first time in KAMAZ rally were used 25 'wheels. The cabin was a 'corporate' white body and yellow-blue. And only since 1995 KAMAZ-MASTER become so familiar to us 'humped' shape and the white-blue color. Photo 3 – KAMAZ-49252 Photo 2 – Kamaz 49251 in 1995 year there were KAMAZ-49251 with the engine Cummins 14 500 hp (Photo 2) and KAMAZ-49252 with the engine YMZ-7E846 750 hp (Photo 3). Outwardly, they differed in that at KAMAZ with the Yaroslavl engine on the roof of the body were two exhaust pipes and two inlet (photo 4), and on a machine with a Cummins engine air intake pipe and one (photo 5).

Photo 4 – KAMAZ-49252 Photo 5 – Kamaz 49251 in 1997, appeared the next modification: KAMAZ-49255 with the engine YMZ-3E847 capacity of 1050 hp (Photo 6). Machines are constantly changed not only internally: to change the engine power, but apparently: there were 3 types of body type 'box' and about 4 options 'hunchback' body. Photo 6 – Kamaz 49255 Since 1998, the main 'combat' vehicle was KAMAZ-49252 with the engine JAMZ-7E846 capacity of 830 hp. KAMAZ has received new platform and body as well, according to the requirements of FIA, 20 'wheels instead of previously used 25' wheels. Here is how responsive the reliability of the Yaroslavl Engine Mechanical Engineer engines team 'KAMAZ-MASTER' M Myasoedov: 'The engine we have since 1997 in three seasons was 75,000 kilometers, was on three machines. This engine is lucky. He won the 'Master Rallye' in 1997.

After that the car was destroyed. Made another order the same engine – won the 2000 Rally 'Dakar – Cairo'. And this machine was dismantled. On a happy engine is already the third Kamaz won 'Dakar-2002'. We also have older engines YMZ veterans: one went 200,000 miles, the other – 150 000. They travel to 1995 and participated in fifteen or sixteen rally type 'Dakar'. Photo 7 – Kamaz 49256 in 2002 on the basis of KAMAZ-49252, a new modification of the KAMAZ-49256 with the engine YMZ-7E846 power of 830 hp (Photo 7). From previous versions it was different the fact that the engine was not placed in the 'base', and over the front axle in connection with the changing requirements of technical regulations for members of the group T4. And while these changes became known for only three months before the start of the rally Paris-Dakar, it has not prevented our riders with the honor to win it. Photo 8 – Kamaz-4911 The last modification – it appeared in 2002 KAMAZ-4911 (photo 8). Externally it is similar to its predecessor – KAMAZ-49256, and also has a motor located above the front axle, but at the same time and very different – a different transmission, gearbox, axles, drive … Also, unlike the previous model, this KAMAZ was ommologatsiyu FIA. In November, a month before the start of Paris-Dakar rally, he received a new body (photo 9). Photo 9 – Kamaz-4911 Here are the most important titles won by team "Kamaz-Master ': 1995 – winner of the' Master Rallye '

Coal Moving Bulldozers

Coal Moving Bulldozers

A bulldozer with specialized dumps for moving coal, wood chips and peat rear tractor ballast weight is suspended from acting as a counterweight. To work in extreme situations when clearing blockages in the MOE used bulldozers Komatsu with blade 8 and 81) reduced width, which fit into the railway gauge. This allows a high degree of willingness to work as bulldozers with an attached blade are in the open platform in anticipation of an order for shipment. On the bulldozers of the middle class traction firm Liebherr uses hydraulically reamer, which the cab can be installed at any angle to the dumps. When transporting Bulldozers on trailer reamer turn back, and blade fits into the envelope. Similar dumps applies firm Fiat-Kobelco. Dumps for garbage collection are designed to move the waste to landfills. The shape of this straight blade, with increased width and curvature of the surface of the front plate, as well as the height of the peak, roughly equal to the height of blade.

When using such dumps tractor units subject to additional alterations to protect them from sharp objects and abrasive materials, suspended behind the tractor ballast weights. These dumps provide firm Saterrillar , Dressta and Liebherr . Kustorezny Blade (V-shaped), produced Saterrillar and Komatsu, intended for clearing overgrown with shrubs and low forests of the areas under construction. Lowered into position in the form of angled blade cutter formed by two cutting blades, glide on the earth's surface, cut shrubs and small trees and dump them into the sides, forming a passage for equal widths of blade. Security fence as a steel frame protects the tractor from damage if dropped cut trees. Kustoreznye dumps are made by firms Rimco and Rome. Dumps-stubbing – either dumps lattice form with teeth or teeth that are attached to the front plate straight blade. They are designed to extraction from the soil of large stones and tree stumps and transporting them to close the distance.

The tractor is equipped with top of an additional protective barrier. Such dumps produced by "Saterrillar, Komatsu, Liebherr, Rimco and Rome. The right choice consumer bulldozer blade is the main condition for achieving the best possible performance. First of all, we should evaluate the possibility of digging the ground blade, traction and performance characteristics bulldozer. The possibility of digging the soil are determined by the ratio of the maximum traction bulldozer to the length of the knife blade. The higher the value, the more stable soils can develop a bulldozer. Traction characteristics bulldozer estimated its operating weight, design of Track and transmission. Speed characteristics determine the cycle time of a bulldozer. The smaller its value, the above shall be the rate of working and vehicle movements, and hence higher productivity bulldozer. Engine power, per 1 m3 of loose soil in a prism drawing, in practice, is used to estimate selection blade on the ability to move the material with a large working speed. Transportation speed, especially reversing determine the return time a bulldozer to the starting position.
