More recently, dumpers and special vehicles for the carriage of bulk cargoes have become the hallmark of the plant TONAR, which has long been famous for its trailers to road transport. I must say that dumpers are a special category of heavy equipment used in mining and coal industry. A feature of these trucks is that they are operated on the short arm of up to 10 km on haul roads where there are no restrictions on weight and dimensions. Dump trucks needed for work in off-road conditions, should be extremely reliable and maximum capacity. That is the machine with the designation of TONAR-4525 created some time ago. Dump truck was developed taking into account the exploitation in various regions of Russia. His price was lower than imported counterparts, but the list of components used on this model, one can study the geography of Russia. The engine in the suburban truck Yaroslavl and Tutaev engine plants, springs he Chusovskaya, the torque rods from the factory "Rosstar", and the frame body made of high-strength steel manufactured in Orekhovo-Zuevo district, the plant "TONAR". Thus the plant "TONAR" developed dump truck that met the modern requirements of the country in import substitution.

At the end of December 2013 in the Vladimir quarry (sue UWC) passed the test of Tonar-4525 with a body "bucket" type, designed for transportation of rocks with a large diameter fractions. Tonar-4525 was put in a line for the transport of rock dolomite rocks along with imported "kararname". Shoulder carriage from loading until a crushing plant was 1.2 km. After the first trial trips, it was decided instead of two imported trucks to put one Tonar-45251 with a lifting capacity of 45 tons and a body volume of 25 cubic meters. 

In 2014, in addition to Tonar-4525, with a body of rock made a dumb truck-uglies. He was the first and received a code TONAR-45251. At the end of July 2014 Tonar-45251 started to work on the transport of slurry to the largest enterprise of the mining sector Temirtau (Kazakhstan) "JSC was ArselorMittal Temirtau". Standing on the line, "Tonar" has replaced a pair of Chinese trucks. 

In August 2016 TONAR introduced its first conventional road train to operate on haul roads. It consisted of a truck TONAR-45252 and two-section semitrailer TONAR-95405. The customer trains with capacity 116,7 tons became the largest Russian diamond mining company ALROSA.

And here in the spring of 2017 TONAR presented two career conventional dump truck body to transport coal and rock, which replaced the cabover models. The creators claim that the new machine it is the result of drastic change of concept and major components of the machine. Therefore, from the point of view of career construction are produced by Tonar second generation is a completely new machine. As noted, the novelty of 45 tons capacity have kept previously used the name Tonar-45251. In fact, with the advent of these machines LLC "machine building plant "TONAR" was the first and only Russian manufacturer with original mining machines of its own design. The developers are confident that their new creations will become serious rivals of 40-ton "BelAZ". As in the case with the previous model, spar frame and body for the new truck are the developments of the plant. Also, the company was made and a double cab, hood and front bumper of the car.

Despite their apparent similarity, the two machines differ in appearance. The first released truck with carrier frame No. 41 tested as Tonar-45253. But while both cars, according to the marking on the frames, are index 45251ОН. The second truck is equipped with a frame number 52. The first sample is equipped with V-shaped 8-cylinder turbo diesel engine TMZ 8437.10 displacement 17,24 l, developing 425 HP of the Second car fitted with inline 6-cylinder diesel "six" Cummins QSZ13-C450-II with a volume of 13.0 l 450 horse powerS. both models are equipped with 6-speed automatic transmission Allison 4500 with retarder. Fuel tank capacity stainless steel 360 l can be equipped with external protection made of steel sheet.

Interest suspension design rear axle HANDE Chinese companies. Here we have used the balance suspension rubber elastic elements. This solution is capable of reliable work in conditions of particularly large axial loads not addressed by conventional leaf springs. The vertical load on each axle is transmitted via four elastic element, longitudinal and lateral loads are reactive rods with rubber-metallic hinges. Permissible load on each axle is 25 tons, with the main suspension parts have a three-fold margin of safety. Compared to commonly used heavy equipment hydropneumatic suspension, suspension rubber-elastic elements are structurally simpler, virtually maintenance free and provides performance at temperatures from -60 to +50° C. To increase the patency of millennia differentials supplied with locking mechanisms. A similar device embedded in the center differential. To drive the lock buttons on the dashboard.

Suspension the front axle of upavasa and "Skalnik" the same pneumonectomy with few-leaf springs. But the beam of the machines are different, as the design of the steering. On the "Skalnik" it's completely hydraulic, and please – power. However, given the difficult working conditions, the hydraulic actuators with bipod and rods are duplicated and are on both sides of the driven axle.

One of the main features of the design trucks was the cabin of own production (all-metal, double, made of aluminum), which significantly reduces the cost of the finished product. Cabin plewase inside slightly larger than the "Skalnik". Dump trucks are also differences in the layout of the knobs and switches on the control panel. If we evaluate the level of comfort of the workplace and the passenger seat, uglies no different from the "Skalnik".

A new conventional Tonari different dump bodies. Plewase it is more spacious and is equipped with a tailgate with top hinge. The body is made of steel 09G2S, side thickness 6 mm, bottom – 10 mm. Body rock made of the same steel, but more durable. For boards used plate thickness 7 mm bottom, 12 mm. Both body equipped with heated exhaust gases and rods to remove stuck between the rear ramps of stones. The lift cylinders Penta body outside vnutricerepnogo the frame. The lower ends are fixed to the cross beam located in the base of the truck. This gave the opportunity to free up space inside the frame for the nodes in chassis and lower the center of gravity of the machine. By the way, on these trucks, a node is either covered with thick metal sheets, or hidden in armored boxes. As, for example, battery.

Regardless of the type of body, bonnet karyernyi TONAR-45251 equipped with a system of automatic centralized lubrication Lincoln Quicklube with 24 points. It eliminates the ingress to the lubrication of abrasive particles (dust, sand, coal dust) and significantly increases the service life of the pins, fingers, rods, leaf earring, supports, suspensions cabs, etc.

It should be noted that the truck tutaevsky engine will be tested in the Rostov region, and the model with the Cummins engine in the Republic of Buryatia.

In addition to these trucks, were presented and other novelties factory TONAR.

Agricultural trailer PT-10, specially designed for the transport of grapes. To avoid oxidation, the internal coating of the body is made of stainless steel. The tightness of the trailer provides a hydraulic roof. Body volume – 10 cubic meters.

Double-deck semi-trailer cattle truck TONAR-98262 intended for transportation of pigs. A distinctive feature of this model are stationary floors. The lack of hydraulics facilitates construction and ensures ease of operation. The capacity of the trailer – up to 150 heads.

TONAR-952345 – new model in the line of lightweight tipper semi-trailers for the transport of coal. Body volume is 29.7 cubic meters. Design four-axle semi-trailer can carry up to 28550 kg of cargo without violations. For the efficient operation of the coupler requires a tractor with the wheel formula 4x2. Automatic awning with electric drive reduces the time to "removable curtains" body with half an hour to one minute, and also increases the safety of the driver, especially in winter.

After the technology demonstration took place traditional a press-conference on which has made by the specialist Cummins, Alexis Hove, the representative of the company WABCO Alexander Vinokurov, head of the Department of road construction equipment of the Ministry of industry and trade of the Russian Federation Alexey Yartsev, technical Director of MZ "Tonar" Yuri Weinstein.

The event continued with a tour of the factory where everyone could see and appreciate the degree of modernization and robotization of production: the complex welding of spars, bodies, axles, manufacturer of cabs, etc.

The tour ended at the entrance to a factory dining-room where guests were already waiting for a delicious dinner and warm atmosphere for intimate conversations, greetings and wishes.

This presentation was a vivid evidence that interest in the technology of domestic production has not only not diminished, but, on the contrary, is growing every year. A large number of visitors (and there were about 150 people) said that the event was an important event for those working in the field of transportation and in any way associated with the automotive industry.
