Tipper road train consisting of a Tonar-6428 truck tractor and Tonar-9523 + Tonar-95233 semi-trailers

To transport agricultural products - seeds, grains, cereals - special grain trucks are used. Semi-trailers are designed to transport cargo from the fields to the storage location. The vehicles have a chassis with excellent maneuverability.

High sides allow the body to be fully loaded. The grain truck market is represented by hundreds of models. Let's look at the technical characteristics of the Tonar 9523 semi-trailer.

General characteristics of the Tonar 9523 semi-trailer

The semi-trailer of this model has an automatic tailgate locking mechanism. This saves time when loading the contents of the body. The semicircular cross-section of the body reduces the truck's own weight. The trailer has three axles, the body volume is 28 cubic meters.

Purpose and benefits

Dump semi-trailer "Tonar" 9523.
Dump semi-trailer Tonar 9523 is designed for transportation of grain, legumes, buckwheat and other bulk products. The truck delivers goods “from gate to gate” - that is, from the field to warehouses, trains, and planes.

The main advantage of the equipment is high cross-country ability and body reliability. The design features allow cargo to be transported without loss, which is especially important in the case of bulk goods.

Speaking about cargo transportation in general, the use of grain semi-trailers is much cheaper than air transportation and transportation by rail.

Dimensions and weight

The curb weight of the trailer (the figure indicating the weight of the vehicle without cargo) is 8,720 kilograms. Its carrying capacity is 28.7 tons. The length of the trailer does not exceed 8,960 millimeters. Width – 2,540 mm. The car is low: from the ground to the top of its head is 3080 millimeters.

Design Features

The model is equipped with a rectangular body with a sloping front. The bottom is rounded, the tailgate is straight, and opens automatically when lifted. There is an additional unloading hatch with a mechanical manual drive. The maximum elevation angle is 48 degrees.

Often the body is additionally coated with a polymer coating. This prevents sticking and freezing. You can also put up an awning, which will be useful in bad weather. The semi-trailer has an air suspension and three brake systems. The main brake system operates thanks to a pneumatic drive and has ebs.

Main modifications

The Tonar semi-trailer has several modifications. The differences between them are small, mainly in terms of the transported mass of goods. Let's look at the most common models and their parameters.

Main modifications

There are more than two dozen different modifications of this dump truck, most of them differ in body volume, add-ons, cargo weight and unloading side. Let's list the main ones.

Tonar 9523 with extended sides - has exactly the same characteristics as the main dump truck, however, due to the extended sides, the volume of the trailer has increased to 43 cubic meters. This modification is ideal for transporting scrap metal, as well as bulk cargo with low density, such as grain or vegetables.

Tonar 95234 with increased load capacity with side unloading - differs from the standard model in the number of axles, of which there are one more, thanks to which the trailer can be used on public roads, while complying with the standards for the load on one axle. The total volume reaches 58 cubic meters, the maximum cargo weight is 46 tons.

Tonar 952342/44 grain carrier - this model also has 4 axles as the previous version, exactly the same load capacity of 46 tons, but has a large body volume: without add-ons 60 cubic meters, with add-ons the total volume reaches 74 cubic meters.

Tonar 95235 is a dump semi-trailer with bottom unloading. Designed primarily for transporting cargo such as potatoes and beets. In terms of cargo weight, its characteristics are identical to the standard one, but its volume is 47 cubic meters.

Tonar 95239 is a dump semi-trailer with side unloading for high-density cargo. The total volume is 25.5 cubic meters. Maximum cargo weight is 31 tons. The main feature of this trailer is its tightness, which is achieved thanks to a tensioned awning. Available in two versions with left and right side discharge.

Tonar 952362 is a three-axle dump truck with rear unloading. The body volume is 40 cubic meters, the maximum weight of transported cargo is up to 43 tons. It is also primarily used for transporting high-density bulk cargo, such as crushed stone, sand, and coal.

Operating requirements

Trucks are unpretentious equipment.

However, there is a set of rules, if followed, the semi-trailer will serve you for years:

• One of the main ones is that the weight of the transported cargo should not exceed that indicated in the technical specifications. Otherwise, the load on the truck will increase. This can have a negative impact on the axle.
• Do not forget that the center of gravity of the load should be located in the middle of the body.
• A trailer with TEBSE can only be used in conjunction with tractors that have a five- or seven-pin ABS socket.
• The described semi-trailer models are designed for operation in temperate climates. This means that the air temperature should be no less than minus 45 and no more than 45 degrees Celsius. Humidity in this case should not exceed eighty percent.
• The trailer must be coupled to the tractor on a hard, level surface.
• If you leave the car on a slope, do not forget to install wheel chocks under the wheels.
• The body should be unloaded on level ground. The longitudinal slope should not exceed 4 degrees. If you notice the slightest sign of trailer instability, stop unloading.
• In the back you can transport bulk products and even construction materials. But remember that transporting clay is strictly prohibited by the manufacturer.

MULTIPLE DUMP

The topic of profitability of transportation of bulk construction cargo is always relevant: the more one vehicle transports in one trip, the more profitable the transportation itself is. But the carrying capacity of a single dump truck is limited, so there is only one way out - the use of road trains. A new word in this direction was said in the Moscow region.

The very idea of ​​a tipper road train, consisting of several multi-axle semi-trailers, was spied on by the Americans. In the USA, similar road trains have long been created to remove rock from a quarry and further transport it along public roads. Moreover, they are not limited to trains such as a tractor + two semi-trailers and, without hesitation, hook up to four towed cargo units. Moreover, each such semi-trailer can have up to five or six axles, which increases its load capacity.

But such vehicles are more likely to be exotic, so in the Moscow region they took a more practical route, limiting themselves to two three-axle dump semi-trailers coupled to each other. The total weight of such a road train should not exceed 64,270 kg, and the carrying capacity should not exceed 48,850 kg. When using a three-axle tractor, the weight of the loaded road train is distributed fairly evenly over all nine axles and theoretically does not exceed the design load of 9 tons on each axle, which makes it possible to operate the road train even on roads with low load-bearing capacity, however, provided that there is no overload.

By the way, about overload. Knowing the desire of our operators to squeeze everything that is possible, and sometimes what is not, out of the equipment, testing of the new road train was carried out with almost double overload, filling the bodies with wet sand. According to the most conservative estimates, the two bodies contained almost 80 tons of cargo, and the total weight of the entire road train was close to 100(!) tons. Such overload was necessary not to show a margin of safety, but quite the opposite - to identify the weak points of semi-trailers . For example, when unloading wet sand, testers noted a deflection of the right (lower during unloading) side of the body; as a result, it became necessary to make an additional connection of the sides with a beam in the center of the body (it is clearly visible in photographs during unloading).

Technical characteristics of the dump hitch “Tonar-9523” + “Tonar-95233”

In addition to the permissible axle loads, questions arise: to what extent is the operation of such a monster permitted on public roads, and will there be problems with the traffic police regarding the length of the road train? After all, together with the tractor, the road train crosses the seemingly maximum permitted 20 m? But here we must not forget one addition to the rules that allow the maximum length of a road train consisting of two (!) trailers - 24 m. And a road train near Moscow, consisting of just two semi-trailers, more than fits into this parameter.

When designing dump semi-trailers, the plant's designers had to solve non-standard problems. It is clear that with such a coupling only a lateral stall is possible. But the plant recently launched the production of dump trucks with high sides and a rounded bottom, and I wouldn’t want to give them up. But in order to unload such a body sideways, it had to be turned over at an angle greater than 90°. This condition required, firstly, to shift the tipping axis of the body much higher in order to prevent the center of gravity from shifting sideways from the axis of the road train and thereby maintaining the stability of the semi-trailers during unloading, and secondly, to carry out hydraulic equipment for the trailers according to a dual-circuit scheme, since the body is now cannot return to its original position under its own weight, and it had to be returned forcibly by forcing the hydraulic system to work in the other direction. Here it would be useful to recall that all hydraulic equipment on the Tonar is used only from the Italian company PENTA.

Among the design features of the road train, it can also be noted that all six axles produced by Tonar itself are installed on air springs and equipped with new generation ABS TEBS-E. This anti-lock braking system, unlike the usual one, has a gyroscope built into the unit, which allows you to control the horizontal stability of the semi-trailer and helps control the load on each axle during operation, redistributing it if necessary. The air suspension also improves the smoothness of the entire hitch and makes it possible to artificially lower the ground clearance of the road train when unloading, again for better stability. Moreover, the manufacturer strongly recommends using a tractor with air spring suspension in this hitch, based on the same considerations. On each semi-trailer, the first of three axles is a lifting axle - it automatically rises on an empty semi-trailer and lowers when loading, which allows for a slight reduction in fuel consumption and improves the maneuverability of the road train during empty runs.
