What and how is a GAZelle trailer made of?

Types of trailers

Trailers are divided according to the distribution of weight and load between the tractor and the trailer:

• The trailer is a self-contained vehicle and can be attached to any tractor using a drawbar through a coupling device (for example, a hook-and-loop system). The weight of the load is transferred to the road through the supporting frame of the trailer and then exclusively through its own wheels; The connection between the trailer and the tractor is used only to transmit traction force.
• The semi-trailer is coupled to a specialized truck tractor through the coupling device (“saddle”) of the tractor using a coupling pin. The weight of the load is completely transferred to the supporting frame of the trailer, and then distributed between the semi-trailer’s own wheels and the wheels of the tractor. The connection between the trailer and the tractor serves to transmit both this load and the traction force. The semi-trailer is not able to move without being connected to the tractor; To ensure its stability during this time, it is equipped with folding or retractable stands.
• The dissolution is a hybrid of a trailer and a semi-trailer and is designed for transporting long loads as part of a specialized road train. The transported cargo rests on special supports - the so-called “bunches”: its front part is on the tractor bunks, and the rear part is on the bunks; in this case, the weight of the load is partially transferred to the tractor, and partially to the supporting frame and wheels of the dissolution. To ensure the transmission of traction force, the dissolution is equipped with a drawbar of constant or variable length; sometimes the role of the drawbar is played by the long load itself.

Based on the number of axles, trailers are divided into single-, double- and multi-axle. According to the type of cargo platform (the type of cargo transported), in domestic practice, trailers are usually divided into flatbed, dump, dump trailers, tank trailers, van trailers, heavy-duty trailers, light trailers, and special trailers. A similar division applies to semi-trailers.

In the designs of trailers, semi-trailers and trailers, various wheel steering systems can be used to improve the handling of the road train. Coupling devices are usually standardized. Trailers and semi-trailers can be equipped with active wheel drive from the tractor engine (“active road train”); such a drive is usually carried out mechanically through a coupling device, or a hydraulic drive is used. In a number of designs of active road trains (the so-called two-link road train), the engine can be located in the rear section.

The term “trailer” is also used informally (from the English trailer “trailer”). A trailer is a trailer or semi-trailer specifically designed for transporting equipment, vehicles or special cargo (heavy, long, etc. - “heavy trailers”). Sometimes trailers are also called passenger van trailers, equipped as mobile living quarters used for living and recreation while traveling, and sometimes as temporary housing.

How much does it cost to transport a tractor?

Delivery costs depend on many factors, including:

• type of tractor;
• transportation distance;
• independently obtaining a permit or ordering a service from a logistics company;
• method of transportation, type of cargo;
• the need for the services of slingers;
• presence of an accompanying car;
• region of service provision;
• intercity or international transportation;
• weight and dimensions of the machine;
• route features.

Only the company that will carry out the transportation will be able to tell you the exact price tag for the services.

How to make a trailer from a semi-trailer?

So, I hope it’s clear how a trailer differs from a semi-trailer. Including from the photographs given. But can a trailer be converted into a semi-trailer and vice versa? Making a semi-trailer out of a trailer is problematic. Yes, it probably doesn’t make much sense. But it is definitely possible to convert a semi-trailer into a trailer. Pleasure, of course, does not come cheap. After all, for this to happen, the front of the semi-trailer needs to rest on something. In this case, the semi-trailer can rest not on a truck tractor, but on a dolly with an installed fifth-wheel coupling device.

Types of dolly trolleys

There are two types of dolly trolleys. The first type is a dolly trailer. It has a drawbar in the front part with a coupling device that clings to the car's tow bar.

Two-axle dolly for semi-trailer

A rolling trailer can be with unsteered axles and with steered (self-steering) axles.

Eight-axle road train

Similar road trains can be found on highways in some European countries and Scandinavian countries. We are unlikely to ever see megaliners on Russian roads. In the countries of the Customs Union, different rules apply for road trains.

Large manufacturers of trucks in Russia and Belarus produce mega couplings, but for other countries.

The second type of dolly is designed to increase the load capacity of a semi-trailer and is called a dolly. It is mainly used with low-bore heavy-duty semi-trailers. Such a dolly clings, again, to a truck tractor.

What documents are needed to transport a tractor?

At the stage of preparation for the delivery of oversized cargo, it is necessary to collect documents to obtain permission. The legislation provides for the following required package of documents:

• driver's license;
• vehicle registration certificate;
• insurance policy;
• certificate of passing state technical inspection;
• documents for the tractor (vehicle passport, registration certificate, handwritten power of attorney for transporting the tractor);
• waybill;
• waybill.

Transportation without documents may result in fines. In this case, the tractor may be taken away to a fine parking lot until the circumstances of the case are clarified, and an administrative violation report may be filed against the driver.

Next series

A real revolution in the field of creating an up-to-date model of a light-duty truck with a semi-trailer that meets international standards was the release of a new series in the GAZelle family - Next.

Launched into production in the spring of 2013, modified on the basis of GAZelle-Business models, the vehicles are now equipped with an independent front suspension with linkage control and springs, and rack and pinion steering with hydraulic booster.

These improved specifications are responsible for significantly optimizing the truck's ride quality and road stability compared to its predecessor.

A more advanced and comfortable cabin is another distinctive feature of the Next series, which, along with the impressive size of the bumper, attracts attention when you first look at the modernized car.

The stamping and welding equipment of the cabin was carried out by specialists from the LG concern. The frame of this structural element is completely galvanized; high-quality sealants and anti-corrosion agents were used during its assembly.

The cabin wings are made of durable plastic. In addition to the exterior enhancements, the interior has also received significant improvements.

The changes affected the organization of space by placing numerous compartments, shelves, and stands for all the things the driver needs.

Intelligent seat adjustment even includes individual settings for lumbar support. also been significantly expanded, vibration has been reduced, and sound insulation has been improved.

The first models were equipped with a Cummins turbodiesel power unit; subsequently installed engines could be either gasoline or gas.

The latest cars are equipped with an EvoTech 2.7 engine with mandatory compliance with the Euro-4 environmental standard and with the subsequent possibility of modification to the Euro-5 and Euro-6 categories.

The cooling system of the power plant has been improved by increasing the radiator ventilation area. The Webasto pre-heater guarantees trouble-free engine starting in any climatic conditions.

Unprecedented measures have also been taken to improve the operational safety of the modified version. Firstly, the braking distance was shortened.

In addition, dynamic stabilization (ESP) and traction control (ASR) systems have been added. At the request of the consumer, airbags can be installed on the GAZelle-Next.

The carrying capacity of a vehicle with a short wheelbase (5,630x2,068x2,137 mm) is 1,440 kg, and that of a long-wheelbase truck (6,709x2,068x2,137 mm) is 1,270 kg.

Important! The service life of the truck has increased significantly – up to 150,000 km. The frequency of mandatory maintenance for these vehicles is set every 20,000 km.

The warranty on the car from the manufacturer is 2 years, which is significantly longer than this period for analogues similar to this car.
