KamAZ-55111: technical characteristics

Probably, there is not a single person left on the territory of the countries of the collapsed Soviet Union who has not heard of such a company as KamAZ. For a long time, this automobile concern has been producing several types of vehicles, the most popular of which, without a doubt, are dump trucks.

It is worth noting that the company was opened in 1976, 39 years ago, and to this day they have already managed to produce a huge amount of equipment. At the same time, since 1983, Tatra dump trucks have also been produced.

About the history of the model and its place in the KamAZ production program

KamAZ-55111 dates back to the mid-70s of the twentieth century. The rapid economic growth and construction boom that unfolded this decade has created an increased demand for trucks of this class. But the USSR auto industry did not yet have a sufficient number of models of such dump trucks. In 1977, serial production of the KamAZ-5511 dump truck with an all-metal welded body began.

This truck had a carrying capacity of 10 tons and was perfectly suited for transporting any cargo, primarily bulk construction materials. It was equipped with a hydraulic body lifting mechanism, with electro-pneumatic remote control from the driver’s cab.

KamAZ-5511 was used literally everywhere: on construction sites and in various industries; in the construction of roads and bridges; in agriculture, etc. More precisely, it is still in use: this model remained on the KamAZ assembly line until 1990, and some of these trucks are still “in good health” and continue to work.

KamAZ-55111 became a modernized version of the 10-ton KamAZ-5511. It differed from its predecessor in having a shorter body than the 5511, and, accordingly, better maneuverability. The vehicle's carrying capacity increased to 13 tons. The machine is designed to operate on roads designed for vehicles with an axle load of 100 kN (10 tf).

Otherwise, it was the same 6x4 three-axle dump truck as before. In the first years, KamAZ-55111 had the same cab as the original model 5511 - with round, high-mounted headlights. Subsequently, the KamAZ-55111 cab was restyled, like the cabs of other Kama truck models.

Visually: KamAZ-55111 with an old and a newer cabin. The body has also changed, noticeably increasing in volume.

In 1998, the Kama Automobile Plant began producing a more modern model of a three-axle dump truck, which received the industry index KamAZ-65115. The carrying capacity of this truck was increased to 15 tons. The modernized KamAZ-65115 finally replaced KamAZ-55111 in the plant’s production program. This happened in 2012.

Another related model is the KamAZ-65111 three-axle dump truck with a lifting capacity of 14 tons. This is an all-wheel drive truck with a 6x6 wheel arrangement, designed for use in difficult road conditions and off-road conditions. It continues to be produced to this day.

Modifications of the KamAZ-55111 dump truck

Over the years of production, in addition to the basic model of the dump truck, the production of several specialized modifications of the KamAZ-55111 was launched, namely:

• KamAZ-55111-016-02 is a dump truck designed to work with a trailer as part of a road train. Equipped with a towing device and hydraulic outlets that ensure lifting of the trailer’s cargo platform;

• KamAZ-55111-018-02 - a truck with a reinforced gearbox, a 240-horsepower diesel engine, an increased fuel tank of 350 liters and heating of the dump platform with exhaust gases;
• KamAZ-55111-018-13 - a dump truck with an engine boosted to 260 horsepower, a cross-axle differential locking system and a reinforced clutch system;
• KamAZ-55111-040-02 - a truck with an all-metal dump platform increased to 8 cubic meters

KamAZ-55111 dump truck engine

The engine of this model is classic KamAZ - model KamAZ-740. Over the years of production, various modifications of this diesel engine were installed on the car - both naturally aspirated and with a turbocharging system. The most widely used version of the KamAZ-55111 was the KamAZ-740.51-240, with a turbocharging system and intercooling of the charge air.

Like other modifications, it is an eight-cylinder diesel engine with a V-shaped cylinder arrangement. Its working volume is 10.85 liters, and its rated power is 176 kW, or 240 horsepower (at a crankshaft speed of 2200 rpm). The power unit meets the requirements of the Euro-2 environmental standard. The compression ratio of this engine is 16.5.

To guarantee reliable starting in frosty weather, the engines of KamAZ-55111 dump trucks were supplemented with pre-start heaters of the PZD 15.8106-01 model. This engine provides diesel fuel consumption of around 30 liters per 100 kilometers.

Technical component

The KAMAZ 740.51-240 power unit is a modified turbocharged version of the previous KAMAZ 740 engine, developing power up to 240 hp. at 2200 rpm. The maximum torque of 912 Nm is achieved at 1100 rpm.

The gearbox is ten-speed manual.

KAMAZ-55111 diesel fuel consumption is about thirty liters per hundred kilometers, which allows you to cover more than eight hundred kilometers with a fully filled 250-liter tank. Some modifications are equipped with tanks with a capacity of 350 liters to increase refill intervals.

Like the older model, the KAMAZ-55111 braking system is pneumatic, drum type. The diameter of the drums is 40 cm, the width of the brake linings is 14 cm, and their total working surface area is 6300 sq. cm.

The remaining technical characteristics of KAMAZ-55111 do not differ from its predecessor: 6x4 wheel arrangement, three-seater cab without a berth, bucket-type body has a metal canopy that protects the space behind the cab from the ingress of transported goods, the cargo platform is heated by exhaust gases, maximum speed is 90 km/h.

Transmission

The following mechanical gearboxes were used in the transmission of KamAZ-55111 vehicles: 5-speed 14th modification - without a divider, with a final drive ratio of 7.22, and 5-speed 15th modification with a divider and a final drive ratio of 6 ,53. The gearbox drive is mechanical, remote, with a floor lever. With a divider, the number of gears is 10. To transmit torque from the engine to the transmission elements, a diaphragm or friction dry double-disc clutch was used. Clutch control is hydraulic, with pneumatic booster.

Loading platform and dump mechanism

The standard volume of the all-metal box-shaped loading platform of this truck model is 6.6 cubic meters. The platform is tilted in the direction of the front side. The visor reliably covers all free space between the body and the cabin. The bottom of the KamAZ-55111 dump body is heated by exhaust gases and exhaust pipes, which prevents freezing and sticking of bulk cargo to its base.

The dumping mechanism of the KamAZ-55111 truck consists of a power take-off; oil tank; oil drive; three-stage telescopic hydraulic cylinder; oil pump; pneumatic drive; electro-pneumatic valves and limitation valves.

The power take-off is single-stage. Control occurs from the driver's cabin using an electro-pneumatic starter. The dump body reaches its maximum elevation angle of 60 degrees in 19 seconds, and completely lowers to its standard position in 18 seconds. The volume of the hydraulic system is 33 liters of industrial oil 20 for summer operation, or industrial oil 12 for operation in the winter months.

Cabin of KamAZ-55111 dump truck

The truck is equipped with a standard KamAZ all-metal cabover cab that tilts forward, which is mounted on a frame above a longitudinally mounted diesel engine. Cabin version - without berth. In later modifications, dump trucks began to be equipped with a restyled cabin with a higher roof, but also without a berth. Because a dump truck for transporting construction and industrial bulk cargo is not intended for multi-day long-distance travel.

To access the power unit, the cabin can be tilted in two fixed positions - 42 and 60 degrees. In the newer cab version, a sprung seat with seat belts was installed to improve driver comfort. But in general, the working conditions of the driver of the KamAZ-55111 dump truck and in the updated version of the cab remained quite spartan. The level of comfort in terms of noise and vibration protection of the workplace, ergonomics and ease of control can be called acceptable for the 80s of the twentieth century, but far from modern standards.

Reviews from owners and drivers of KamAZ-55111

Most of the reviews boil down to the fact that the KamAZ-55111 is a good dump truck, but if there was more money, I would have switched to a foreign car long ago. This machine, by and large, is good - both in reliability and in its durability and wear resistance. You can work on it for many years and earn money consistently.

Of course, in our time there are many other imported trucks of this class that are significantly superior to the KamAZ-55111 in all respects - both in terms of carrying capacity and in terms of efficiency in diesel fuel consumption. However, the prices for the car itself and spare parts for it cannot be compared with those of KamAZ.

The shortcomings and outdated design of the KamAZ-55111 are compensated by its unpretentiousness and maintainability. For example, a Mercedes truck cannot always be repaired in places remote from developed civilization. However, KamAZ-55111, like its other “brothers,” requires attention, regular and conscientious care.

“Do not believe those who say that this machine can be repaired in the field, which is called “on the knee.” This is usually said by balabols who won’t do anything in the garage. On the road, I don’t know, you can replace the hose or part of the air duct of the brake system (wind up a temporary one). True, we still need to get to it... Yes, there is a spare wheel. And then, in the “field” you will be tortured to change it. And if the spare tire is screwed to the frame from below, then even in the garage the fastening nuts are still a “thorn”. I believe everyone who is thinking of buying such a used car should have access to a garage service.”

Drivers and owners are divided on the issue of overload. Some say that they can easily load 15-17 tons into bodies with extensions; some say that it is extremely undesirable to overload the car: cracks may appear along the frame. Or you will have to manually (with a shovel!) unload the car: unloading hydraulics is not its “strong and trouble-free” side. If you are transporting soil in the spring or in slush, you need to take into account the waterlogging of the load and ask the excavator operator to “throw less.”

It is also noted that when fully loaded on a long climb, the engine pulls heavily, and you have to pull over to the side of the road to give way to cars and not gather a whole “cavalcade” behind you. The steering regularly requires attention (constant play).

Advantages and disadvantages

You all know very well that large dump truck class vehicles, which are designed to transport large and heavy loads, can rarely be found on city roads. But not everyone knows the reason for this. Of course, many are inclined to believe that this is all due to the dimensions of the KamAZ. You can't argue that there is part of the truth in this, but only part.

In fact, dump trucks are rarely seen on city roads due to their poor maneuverability and this is the main reason. As for this model, thanks to its good maneuverability, it can easily become an ordinary participant in city traffic.

The technical characteristics of front loaders are described in detail in another article.

Another principle for classifying loaders is tracked or wheeled.

Advantages:

• KamAZ-55111 is an excellent vehicle for traveling off-road. Thanks to its design, it copes with all obstacles without problems.
• Due to its medium size (compared to other representatives of dump trucks), this machine does not cover a large radius during turns , which is another big plus and makes it easier to travel if the route passes through the city.
• The platform can be heated.
• This type of machine has a long service life.
• Due to its long service life, another advantage follows in itself, which concerns the ease of maintenance of this type of machine . Breakdowns are very rarely noticed, so you can always reduce maintenance costs.

The KamAZ-55111 is a very good example of how you can purchase a very high-quality dump truck at a relatively low cost. Many years after the release of this car, it remains in the number one ranking. Look at the characteristics of the Kamaz 6520 model with comparable prices.

Drivers choose it for its excellent technical characteristics, reliability, ease of use, as well as the ability to easily and simply replace failed parts. This is a very important factor, since often it is the difficulty of repair that becomes an insurmountable obstacle for drivers who do not have the proper skills in this matter.

Flaws:

1. One of the most important disadvantages of such a machine is its poor ergonomics, which is why many companies and individuals refuse to purchase the KamAZ-55111.
2. The model has already been discontinued by the concern (if the car breaks down and some part needs to be replaced, then you will have to strain and try to find the part from someone else, which, most likely, will be removed from a car of the same model - which means will not be new).
3. The total volume of the Kamaz body is 6.6 cubic meters. meters, which is why not all types of work can be performed with sufficient efficiency.

I would like to note that, despite several shortcomings, the machine has a fairly large number of advantages that put it above many other representatives of dump trucks. The low price completely covers the three above-mentioned disadvantages, which do not play a particularly important role in the operation and use of KamAZ-55111.
