Rotational buses of the last year of production are distinguished by increased technical characteristics. They are specially designed for movement in all weather and climatic conditions.
Constant modernization of the NEFAZ 4208 all-wheel drive bus since 1989 made it possible to get a perfect car at the exit.
The most famous models of this series are produced with a complete set of NEFAZ 4208 11-13, in the amount of 24 passenger seats (22 + 2 in the driver's cab) and a capacity of 240 hp.
Separately, it is worth noting the generation of NEFAZ 4208 24 with a capacity of 280 hp. and a different number of seats. The equipment with the marking 10 or 11 has a passenger capacity of 20 or 22 seats, respectively. Designations 8 or 9 include 16 passenger seats.
Minivariant NEFAZ 4208 03, which is rightfully called municipal equipment, includes only 8 passenger seats. It is particularly compact, but, nevertheless, its declared power reaches 260 horsepower.
A special one was created for transporting a small number of workers (shift workers, fishermen or hunters). There is only a natural ventilation system, but this makes the functionality of the presented model no worse than the NEFAZ 4208 11 13 rotational 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 develops is up to 85 km / h. The fuel tanks are located on the right and left sides of the chassis.
A mechanical 5-speed gearbox is what you need to select the speed in conditions of constant variability of road conditions. Manual transmission and dry double disc clutch - the guarantor of strength and reliability. The risk of the bus getting stuck on the way to the work site is minimized, as the rise of the road can be up to 31% steep.
If the first models had a built-in engine that met Euro 1 standards, now its functionality is focused on the Euro 4 and even Euro 5 environmental class.
Externally, the body looks like a closed van. The main door is located on the right side and has a low entrance, as well as an emergency exit (hatch) in case of unforeseen circumstances. Single doors open outward for complete convenience. A spare wheel is installed on the rear wall of the outer side.
Inside the salon
Padded safety seats with a fixed backrest and tilt angle adjustment, as well as two or three-point seats 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, the cabin has an intercom for communication with the driver's cab, as well as a radio receiver. Excellent thermal insulation keeps the cabin warm throughout the transport of workers.
Double windows with tempered glazing have received excellent recommendations for protection against shattering, and thus have become an additional proof of safety.
Let's take a closer look at the heating and ventilation system, at least using the example of NEFAZ with modification 4208 24 - a full-fledged rotational bus.
Possible additions
Tinting of glasses with special films or finishing with curtains is allowed. If constant trips to difficult climatic conditions are assumed, then air conditioning or additional heating can be installed. Equipping with a winch is possible.
Conclusion
Excellent cross-country ability, reliability and safety are the main reasons for choosing this bus.
