KamAZ-4355 - the first truck left with a "nose"

August 26, 2003 guests of the 6th Internationalcar show in Moscow, was presented KamAZ-4355, which was very surprised visitors to its appearance, different from traditional models. The car had a hood arrangement.

What caused the manufacturer to depart from the already traditional beskapotnyh models, considered the world's most modern and promising?

The reasons for the appearance of the "nose" KamAZ

According to the management of the plant, which wasthe release of a truck of this type will help expand the existing family of all-wheel-drive heavy vehicles that can successfully solve problems in the most inaccessible areas of the North and Siberia. In addition, KamAZ-4355 will be useful for oil and gas workers, rescuers and the army, in forestry and will take a worthy place in these industries among the already proven URALs and MAZs. From the above it becomes clear that, in fact, KamAZ decided to try to learn a new field for activities, find and occupy its own niche, squeezing competitors.

Why the hood?

At first glance, the hood arrangement of the truckseems out of date. So you can talk, if you do not take into account, in what conditions it is planned to operate the machine. The fact is that the front engine layout has its definite advantages. Since the cab is stationary, not tilted, this opens the possibility of mounting various special superstructures on the existing chassis, such as drilling equipment or repair equipment.

The presence of the hood is especially important for northernregions, as in frosty weather there is no need to lift the whole cabin to gain access to the engine. In addition, the designers who are developing the KamAZ-4355, tried to maximally facilitate access to the power unit, making the hood a single piece without sidewalls. It is also worth noting that the hood itself is made of lightweight but durable plastic.

The stationarity of the cabin also allowsfacilitate the task of additional insulation of the cabin. In addition, the hood KamAZ-4355 is equipped with a self-contained heater with adjustable air supply, which can work even when the engine is off.

Known variants of superstructures on the chassis

Hood KAMAZ, exhibited in 2003 in theMoscow, was a version with a metal platform, covered with awning. By the way, he was recognized as the best cargo SUV, for which he received the first prize, far ahead of the competitors - GAZ and URAL. In addition, there he was awarded a special prize for the model's perspective and originality of the design used.

In addition to the standard onboard body, forThere is another application for KamAZ-4355. In particular, the plant, specializing in the production of truck cranes, located in Klintsy, assembled a crane on the basis of a "kapotnik" with the possibility of lifting a cargo weighing up to 25 tons.

And in Ryazan JSC "Centrantstehmash" used a truck chassis to install an isothermal van, which in the future was planned to be used as a shift bus with a capacity of 22 people. Both cars were presented at the 10th international exhibition held in 2005 in Surgut.

Meanwhile, on the basis of the chassis of the "kapotnik"the factory-manufacturer planned the construction of fire fighting vehicles for extinguishing fires on drilling rigs, installing repair equipment for oil wells, and hydraulic lifts. Despite all the plans of the factory workers and prize places at the exhibitions, the KamAZ-4355 hood did not become a serial model, and it is not known how many cars were produced.
