All ISUZU trucks can be divided into categories. Moreover, there are many criteria by which equipment can be divided. For example, layout (bonneted, cab-over-engine, or cab-forward), steered axle arrangement (only front, front, and rear, front and middle, entirely run chassis), transmission types, etc., etc. So the classification of trucks is so extensive that it is simply impossible to list all its options. Furthermore, each carrier will have its priorities, and the key parameters will also be different for everyone – someone needs to have a minimum loading height, and someone will be happy with every additional millimeter of ground clearance.

Let’s see what critical types of trucks exist. Moreover, there are certain points that, to one degree or another, are taken into account by all carriers without exception. So here they are worth stopping separately.

By number of axles

By the number of axles, the most popular Isuzu two- and three-axle trucks with wheel arrangements 4×2, 4×4, 6×4 and 6×6. The first three options, as the most popular, are available in the ISUZU model range. Here it is worth considering what category of roads the car will work on – in many directions, there are seasonal and permanent restrictions on axle load, and multi-axle vehicles are more profitable when transporting heavy loads. In addition, there are differences among cargo all-terrain vehicles.

The tasks of ISUZU ELF all-wheel drive trucks are to ensure movement on roads with muddy, swept snow or icy surfaces. A sort of “crossover” for the transport of goods. The options for four-axle vehicles are also worth mentioning: 8×4 and 8×8.


In terms of composition, the division of technology is the simplest. Either it is a single vehicle or a tractor with a trailer (road train). Moreover, both an ordinary truck and a particular truck tractor, the role of which is only to carry a semi-trailer, can act as a “locomotive” of a road train. The advantages of the first option include the possibility of transporting goods without a trailer. Moreover, loading or unloading such a tandem can be carried out simultaneously in different places, saving time. And the strength of the tractor with a semi-trailer is better maneuverability and smaller dimensions with a comparable capacity. Moreover, the same truck tractor can be coupled with semi-trailers for different purposes.

The entire ISUZU range is designed to work with trailers. Such a road train increases the gross weight by 3,500 kg for the ISUZU ELF and ISUZU FORWARD series and 12,000 kilograms for the ISUZU GIGA series. The family of heavy equipment also has a truck tractor, which, in its parameters, is perfectly suitable for working in the harsh conditions of the construction industry.

By type of fuel

The division into classes of trucks by type of fuel is becoming more relevant every year. For example, if half a century ago we had only two main options: gasoline and diesel fuel, then gas was added to them.

Currently, gasoline engines are used only in the light commercial vehicle segment, where quieter operation and less dependence on low temperatures are more critical than low fuel consumption. However, most trucks have diesel engines precisely because of their greater efficiency than gasoline ones. Working over long distances becomes a significant factor, as it allows you to carry a smaller supply of fuel per kilometer. Gas engines use three fuel options: liquefied propane gas, compressed natural gas methane, and liquefied methane gas.

The first two options are more environmentally friendly and cheaper than diesel fuel. However, their stock on board is limited due to the volume occupied, which imposes significant restrictions on equipment operation with such motors. As an alternative, manufacturers, including ISUZU, offer gas-diesel versions of their vehicles that allow the two fuels to be combined. However, the most promising is the storage of methane in liquefied form. It allows you to work at distances comparable to diesel trucks while maintaining the advantages of this fuel type, making its use very efficient.

By load capacity

Another division of trucks is made by gross weight or by carrying capacity. These two parameters are tightly interconnected, and everyone is already free to choose for himself what to build on when choosing a car. In this regard, all types of trucks are divided into three categories: N1 – with a gross weight of up to 3.5 tons, N2 – with a gross weight of more than 3.5 to 12 tons, and N3 – with a gross weight of more than 12 tons.

Depending on which category your truck belongs to, certain restrictions are imposed on it. Therefore, when choosing a car, it is worth studying in detail such nuances for the region in which you are going to work. It should also be understood that there are alternative gradations of trucks in terms of weight parameters. For example, ISUZU divides its families into a light-duty series – ISUZU ELF with a gross weight of 3.5 to 9.5 tons, a medium-duty series – ISUZU FORWARD with a gross weight of 12 to 18 tons, and a heavy ISUZU GIGA series with a gross weight of 33 tons for the chassis and 48.6 tons for a truck tractor as part of a road train.

By body type

By body type, it is most difficult to divide equipment. The abundance of tasks that are solved with the help of trucks and the variety of goods transported force designers to create bodies that take into account a lot of specific nuances. And the more accurately they are taken into account, the easier and better it will be possible to carry out the delivery. However, four main types of add-ons can be distinguished.

Onboard platforms, vans, dump trucks, tanks. In turn, the first is divided into open and tented. The second is manufactured goods, isothermal, and refrigerators, and the third has options with rear or side unloading. There is also a separate category of trucks – special equipment. These are truck cranes, equipment carriers for the oil and gas complex, airfield equipment, etc. It would help if you did not even list all the variations of add-ons used on such cars. And each of them requires specific nuances from the chassis.
