Tatra T815, Tatra dump truck: load capacity, model range, technical characteristics

The TATRA automobile brand is a true patriarch in the family of self-running strollers. Unfortunately, this is an endangered species, because in 2012 only 496 trucks rolled off the assembly line in the Czech city of Kopřivnice.

It all began in 1850 with the production of horse-drawn phaetons and chaises. The founding father of the company was Ignaz Šustala . The chaises were excellent, half of Europe drove them, and Schustala & Company workshops operated even in Kyiv and Chernivtsi.

Closer to the 20th century, the company switched to the production of railway cars, and the first car in Europe (and this is a historical fact) was assembled by it in 1897. In general, Henry Ford can nervously smoke on the sidelines, as they say. For the first time, a red nameplate with the inscription TATRA on the radiator grill of a car appeared in 1919.

ZIL dump trucks have also not been leaders for a long time, although they continue to be used for agricultural purposes.

Cars

company produced both cars and trucks , as well as self-propelled chassis for artillery systems. The assembly of military equipment, which has special requirements for cross-country ability, load capacity and reliability, predetermined the final specialization of the plant in Kopřivnice as a manufacturer of multi-axle diesel off-road trucks. They work in the construction, forestry and oil industries.

Currently, the T815 truck is produced under the TATRA brand, the production of which began in 1983. This is a whole family of cars on two, three, four, five and even six axles.


Cars from the manufacturer

Over more than thirty years of production history, the T815 has undergone repeated modernizations. Both externally, improving the appearance and ergonomics of the workplace, and radically technical - in 2000, production began of cars with an engine with a liquid cooling system, which had not been installed on Tatras before.

Learn the differences between track loaders and wheel loaders.

One of the leaders in the production of loaders is the French company MANITOU.

Russian loaders are also not inferior in quality.

Technical indicators

Since its release, the dump truck has undergone four major updates, taking place in 1994, 1997, 2010 and 2010. The most significant modifications to the car are as follows.

  1. Development of a new cabin called Terr No. 1.
  2. Modernization of the instrument panel, including the introduction of additional controls and sensors.
  3. Using a liquid cooling system.
  4. Introduction of the new V8 T3C power plant, which fully meets the requirements of the Euro 3 standard.

The truck is equipped with a T815 2A0S01 body with heating and one-way unloading. The car body can accommodate cargo with a volume of up to 10 m3 and a weight of up to 17 tons. The car was originally equipped with an eight-cylinder engine with a displacement of 12.7 liters and a power of 321 hp. With.

The synchronized gearbox has 12 steps. The front and rear axles, which are steered and driven respectively, are equipped with swing axle shafts. On top of the engine is a two-seat tilt-up driver's cab.

Tatra dump trucks are produced in a “northern” configuration, which includes an additional heater that provides heating for the propulsion system, and an electric heater for the oil poured into the engine.

T815 dump trucks

The automobile plant in Kopřivnice produces several models of TATRA T815 dump trucks. Their technical characteristics differ in load capacity, wheel arrangement, and unloading method . Compare them with the characteristics of Howo dump trucks. But what they have in common is that all these cars are all-wheel drive. Their cross-country ability allows cargo to be delivered along any, even just designated roads.

Everyone who has ever worked on these machines notes their high reliability and well-thought-out ergonomics of the driver’s workplace. The Lawn Next dump truck also features excellent ergonomics in the driver's cab.

Design Features

TATRA dump trucks are very unusual vehicles, the design of which has unique elements. First of all, it is worth noting that this is practically the only brand of trucks that are equipped with air-cooled diesel engines. This significantly simplifies their design, but places greater demands on the driver’s qualifications, because the temperature regime of the engine is more intense.

You've probably already noticed that almost identical cars have different numbers of axles. This became possible thanks to the use of a backbone frame, which is also a feature of the TATRA brand .


Dump truck Tatra T815

A number of rear axle shafts (on the Tatras they are made to swing, which makes the suspension completely independent and increases the vehicle’s maneuverability) can be supplemented by mechanically extending the central beam, on which all power units and transmission are mounted.

However, what is good for designers and designers turned out to be not very convenient in operation. All cardan shafts are located inside the beam and access to them is extremely difficult.

Another feature of this brand is heated bodies, into the cavities of which exhaust gases enter . This, of course, is not a revolutionary solution, but it is quite rare. Shakman dump trucks also have a similar solution.

In general, the videos with which you can watch here are outstanding representatives of the independent development of design thought. And the sale of the plant in Kopřivnice to the MAN concern, which took place in 2013, has not yet greatly influenced their originality.

Ergonomics eight hundred and fifteen

“Eight hundred and fifteenth Tatra” is a workhorse without any special frills. It can be characterized, for example, by a phrase from the movie “World Guy”: “Well, you’re not a dude, you can do anything!” Although to say that the atmosphere in the Tatra cockpit is absolutely spartan would mean sinning against the truth.

It has a tilting cab, placed above the engine. Therefore, like all cars with a hood in the cabin, the noise level is higher than, for example, in cars from Mack or Peterbilt.

When creating the T815, designers were able to reduce this figure three times compared to its predecessor, the T148.

In 2003, during the next “facelift”, a slight adjustment to the appearance was accompanied by a change in the dashboard (its shape remained almost identical, several buttons and indicators were added), and the area of ​​the windshield also increased slightly.

The cabin heating remains the same - from an autonomous diesel heater , which is not very good, since you have to breathe a mixture of air with combustion products of diesel fuel. But another solution is not possible in machines with an air-cooled engine.

Operational advantages

During the operation of the Tatra T815 car, a lot of recognized advantages are revealed. In particular, the machine has excellent ergonomics. Dimensions provide the ability to fully view the entire dump truck while driving. A large windshield also plays an important role in improving visibility.

The cabin is equipped with a pneumatic driver's seat with the possibility of individual adjustment. There is also a high-power diesel interior heater and air conditioning. Cab comfort is significantly increased due to minimal noise and vibration levels. All levers and controls are located quite conveniently, so the driver practically does not get tired while operating the dump truck.

The Tatra 815 dump truck performs well in any road conditions, from asphalt highways to complete off-road conditions. The car is also fully adapted for use in the most severe climatic and weather conditions. Thanks to its excellent performance and technical characteristics, as well as many other positive features, the purchase of Tatra 815 trucks is an economically sound and effective investment for an organization engaged in freight transportation.

If simple operating conditions of the dump truck are observed, scheduled maintenance is regularly carried out and, if necessary, replacement of parts and components, repairs are carried out - the Tatra 815 can serve faithfully for several decades.
