To transport work crews to the site of construction work, when the capabilities of a regular bus are not enough, NEFAZ 4208 comes to the rescue with an improved version of itself.
Shift buses of the latest year of production are distinguished by increased technical characteristics. They are specially designed for movement in all weather and climatic conditions.
The constant modernization of the NEFAZ 4208 all-wheel drive bus since 1989 has resulted in a perfect vehicle.
The most famous models of this series are produced with the NEFAZ 4208 11-13 configuration, with 24 passenger seats (22 + 2 in the driver’s cabin) and a power of 240 hp.
Separately, it is worth noting the NEFAZ 4208 24 generation with a power of 280 hp. and different numbers of seats. The configuration with markings 10 or 11 has a passenger capacity of 20 or 22 seats, respectively. Designations 8 or 9 include 16 passenger seats.
The mini-variant NEFAZ 4208 03, which is rightly called municipal equipment, includes only 8 passenger seats. It is particularly compact, but, nevertheless, its declared power reaches 260 horsepower.
A special small-class bus is designed to transport a small number of workers (shift workers, fishermen or hunters). There is only a natural ventilation system here, but this makes the functionality of the presented model no worse than the NEFAZ 4208 11 13 crew bus with a turbofan.
Main technical characteristics
The dimensions of each model from this series may differ slightly, but the average dimensions are as follows - 8.5 * 2.5 * 3.3 m. The maximum speed that the bus reaches is up to 85 km/h. Fuel tanks are located on the right and left sides of the chassis.
A manual 5-speed gearbox is what you need to select speed in conditions of constant variability of road conditions. Manual transmission and dry double-disc clutch are a guarantee of strength and reliability. The risk that the bus will get stuck on the way to the work site is minimized, since the road rise can be as steep as 31%.
If the first models had a built-in engine that met Euro 1 standards, now its functionality is focused on the environmental class Euro 4 and even Euro 5.
Externally, the body has the appearance of a closed van. The main door is located on the right side and has a low entrance, and there is also an emergency exit (hatch) in case of unforeseen circumstances. Single doors open outwards for complete convenience. A spare wheel is installed on the rear wall of the outer side.
PURPOSE AND TECHNICAL CHARACTERISTICS OF THE CAR
NefAZ 4208
is a special bus that served as the basis for the production of more than 20 different modifications of superstructures similar to it. The superstructure is installed on the KamAZ 43101-43114 chassis. Thanks to the 6x6 wheel arrangement and the KamAZ 740.10-20 diesel engine (the vehicles are equipped with more modern and powerful versions of engines), the bus has high cross-country ability. Base length 3340 mm (for superstructures with an increased number of passenger seats in the body, the base increases by 1320 mm). Engine power of 220-260 l/s allows the car to reach speeds of up to 85 km/h. In addition, the car is equipped with a winch.
The machine is equipped with a five-speed three-way manual transmission. The torque is distributed by the transfer case between the constantly running front and rear wheels of the car using a planetary-type center differential and a two-way gearbox. The differential is equipped with pneumatic locking.
Inside the cabin
Soft safety seats with a fixed backrest and tilt adjustment, as well as two or three-point seat belts are an excellent solution for transporting workers.
The folding table, which is located opposite the main entrance to the salon, is convenient to use for a snack. Moreover, there is an intercom in the cabin for communication with the driver’s cabin, as well as a radio receiver. Excellent thermal insulation keeps the cabin warm throughout the entire transport of workers.
Double glass windows with tempered glazing have received excellent recommendations for protection against damage, thereby providing additional proof of safety.
