To increase the amount of cargo transported, reduce the economic costs of delivery, a special vehicle called a trailer is used.

Trailer assignment

The trailer can be most fully described as a non-self-propelled vehicle that allows you to transport various or strictly defined loads due to the power of the tractor, to which it is connected by a special coupling device. Such a combined vehicle is called a road train. It is important to note that the tractor is able to work with several trailers at once.

A feature of the operation of a truck together with a trailer is considered to be more complex control of such a vehicle. Therefore, to work on a road train, a driver needs to undergo additional training and obtain a permit (the corresponding category in the certificate).

Advantages of using a trailer

The main advantages in the operation of the trailer must be considered:

• increase in the amount of cargo transported, sometimes almost 2 times;
• reducing the weight per axle of a road train with an equal load with a conventional truck, which allows you to move on roads that have a weightlimit;
• the ability to create a specialized vehicle, for example, a tractor equipped with a manipulator, will be able to load and transport products not only on its own platform, but also on a trailer;
• reduction of material costs for transportation, including fuel up to 40%.

The main disadvantage in the use of a trailer is considered to be a decrease in the speed of a road train by an average of 30% compared to a truck.

A certain inconvenience should be considered the additional equipment of the tractor (in the absence of serial standard devices) for working with a trailer. Such material costs are one-time in nature and quickly pay off with the constant operation of the road train.

Trailer classification

Trailers for practical use are divided into two broad categories: general purpose and specialized. General transport includes airborne, tented and others that allow the transportation of goods of various nature. Specialized ones include panel carriers, vans, cement carriers, pipe carriers, tanks, dissolutions, car carriers, etc.

An important characteristic of a trailer is its carrying capacity. According to the international classification system, cargo trailers are divided into the following categories:

• up to 0.75t;
• 0.75 – 3.5t;
• 3, 5 – 10 t;
• more than 10 t.

In addition, the division by the number of axles is highlighted.

The trailer GKB 8350 is a two-axle onboard vehicle with a metal platform, with a carrying capacity of up to 8.0 tons,intended for the transportation of goods for various purposes. The main tractor for the GKB 8350 trailer is KAMAZ 5320.

The factory name indicates that the trailer was developed by the Head Design Bureau for trailers, model No. 8350. A photo of the GKB 8350 trailer is presented below.

GKB device 8350

Among the main units of the GKB 8350 trailer, it is necessary to highlight:

• frame;
• swivel trolley;
• front and rear axles;
• drawbar;
• front and rear suspension;
• brake mechanism;
• wheels.

The metal platform has side boards, consisting of three sections, interconnected by special racks, and a rear board. All sides (except the front) can be opened for easy loading or unloading. The metal floor of the platform is covered with special wooden panels, which can be dismantled if necessary. To improve the conditions of use, the GKB 8350 trailer can be retrofitted with an awning together with a collapsible frame.

Parameters of GKB 8350

The characteristics of the GKB 8350 trailer are determined by the following technical parameters:

• Loading capacity - up to 8.0 t.

• Platform dimensions:

  • length - 6, 10 m;
  • height - 0.50 m;
  • width – 2.32m;
  • area - 14, 20 sq. m;
  • loading height –1.32 m;
  • volume with awning - 7, 11 cu. m.
• Track– 1.85 m.
• Base - 4, 34 m.

• Full dimensions:

  • length with drawbar - 8.30 m;
  • length without drawbar - 6.30 m;
  • width – 2.50 m;
  • tent height - 3, 30 m;
  • height with sides - 1.82 m.
• Total weight - 11.5 t.
• Curb weight - 3.5 t.

Trailer modification

Thanks to the technical characteristics of the GKB 8350 trailer, as well as good design, versatility, reliability, ease of operation and low maintenance costs, its widespread distribution and application was achieved. Therefore, for the development of the next, more lifting model, it was taken as a basis. In addition, the significant unification of both trailers achieved at the same time simplified production, maintenance and possible repairs.

In terms of technical characteristics, the main difference between the GKB 8352 and 8350 trailers was the increased load capacity from 8.0 to 10 tons. Such an increase, with a practically preserved design, was achieved by increasing the rigidity of both leaf spring suspensions of the new trailer and manufacturing a swivel bogie from hardened metal. As a result of the modernization, the gross weight of GKB 8352 increased to 13.7 tons.

The relative disadvantage of this improvement was the increase in loading height to 1.37 m (+ 5 mm).

Maintenance

As with any vehicle, forFor reliable and long-term operation of the trailer, it is necessary to carry out technical work (TO) for proper maintenance. The main operations during maintenance are:

• Daily service. Mandatory check of the reliability of the coupling device, serviceability of the brakes, combined rear lights and the presence of wheel chocks. In addition, a visual inspection of the condition of the platform, wheels, suspension, swivel device and the presence of a plate with the GKB trailer number 8350 (right side of the front cross member of the frame) is carried out.
• First service (TO-1). Scheduled lubrication operations are performed in accordance with the GKB 8350 trailer lubrication chart, the brake system is fully adjusted with the replacement of worn-out elements (pads, hoses, etc.), all fasteners are tightened.

Second regulation (TO-2). In addition to all the listed TO-1 operations, the alignment of the wheel axles, as well as the frame and drawbar, is diagnosed. Adjustments are made if necessary. The condition of the metal platform is also checked

The frequency of maintenance of the trailer coincides with the base tractor KAMAZ 5320 and is: TO-1 - 4 thousand km, TO-2 - 12 thousand km. Such a design solution reduces the downtime of the road train and increases the operating period.

Features of operating a car with a trailer

When working together with a trailer, it should be taken into account that the road train has an increased total mass, andtherefore, the length of the braking distance increases. This is important to consider when choosing a safe distance and when stopping, and the effectiveness of the brake system is the most important component of the safe operation of a road train.

Among other features, it is important to highlight the decrease in dynamics. The road train picks up speed noticeably slower, which must be taken into account when overtaking or when changing lanes. When driving in turns, jerks must be avoided when picking up speed or braking, as such actions can cause the trailer and the entire road train to skid.

Reversing maneuvers on a vehicle with a trailer are more complex and require certain skills and qualifications. But in any case, if it is possible to control and assist in such actions, it is better to involve an assistant who monitors the situation behind the road train.

GKB estimate 8350

The GKB 8350 general purpose trailer has been produced at the Stavropol trailer plant since 1974, and the GKB 8352 modification was put on the conveyor in 1980. Thanks to the successful design, reliability and a large number of copies produced, a significant number of trailers are currently on the secondary market. You can buy a copy of the mid-80s in good working condition for approximately 150 thousand rubles.

Given that a considerable number of parts from a KAMAZ vehicle are used in the GKB 8350 trailer, if necessary, it will not be difficult to repair such a trailer, andthe efficiency of using the road train, together with the low cost of maintaining the trailer itself and its versatility, will quickly recoup the cost of the acquisition.

At present, the Stavropol plant has been transformed into the KAMAZ trailer company and continues to produce a variety of semi-trailers and trailers with a carrying capacity of 6 to 13 tons. A further development of the GKB 8350 was the SZAP 8355 universal flatbed trailer, which is very similar to its predecessor in terms of its parameters and technical characteristics.
