Description and technical features of the Ural timber carrier
Vehicles of the Ural automobile brand first appeared during the Great Patriotic War after the evacuation of the Stalin plant located in Moscow. After 2001, the concern is one of the divisions of the GAZ group of companies, and the UralAZ enterprise itself ensures gradual improvement of the model range and technical support. The hallmark of the trucks has become increased cross-country ability among all vehicles on the domestic market. When mass producing the latest vehicles in the Ural line, a universal chassis format is used with the introduction of different variations of the wheel formula.
To ensure performance characteristics, the company uses developments from the world's leading manufacturers producing off-road trucks. The production line includes an advanced quality control system, advanced automated devices for machine assembly, and lean manufacturing technology, which is also used by the Toyota concern.
The timber carrier has increased cross-country ability
A Ural with a hydraulic manipulator is used to move logs and logs, the maximum length of which is up to 23 meters. The device provides the ability to lift and move material, and independently load products into a vehicle.
The high cross-country ability of vehicles ensures the possibility of stable operation of equipment on rough terrain, as well as on public roads.
Advantages and disadvantages of technology
Ural equipment compares favorably with analogues on the market due to its performance characteristics. Advantageous features of the machines:
- High level of cross-country ability compared to most cars on the world market.
- Vehicle maintenance in the event of a breakdown or failure of spare parts can be carried out in field conditions.
- The main units and other mechanical components are highly reliable, resistant to mechanical stress and wear.
- High quality components, thanks to which the car can operate under conditions of temperature changes and other loads.
It is possible to sell a Ural timber truck with a manipulator for use in difficult terrain and on highways. An advantageous feature of the technology is the availability of components even if their production is completed. The main difference between domestic trucks in comparison with foreign analogues is the use of relatively old models of engines, which are significantly inferior in terms of environmental friendliness and fuel consumption.
The design of timber trucks is extremely simple; they are based on a classic tractor with a 6x6 wheel arrangement. A special trailer is attached to the truck, which is secured by a rotating bunk. The structure of the system resembles the letter “P”, and the main task of the device is to maintain a uniform arrangement of timber and fastening during transportation over long distances. The use of a special rotary design makes it possible to overcome the sharpest turns, which eliminates the possibility of using a rigid coupling mechanism.
Using hydraulic manipulators that are installed on the platform chassis, timber is transported. When unloaded, the trailer is mounted on the tractor for ease of movement on highways and narrow sidings.

Selecting a crane for an onboard URAL vehicle
Selecting CMU equipment for a truck requires a thoughtful and professional approach. In this case, you need to decide:
- how often and what kind of cargo you intend to transport;
- at what levels will you work with the cargo, will it be necessary to lower them below the body or, conversely, will it be necessary to unload on a hill;
- how loading and unloading will be carried out, whether it will be done in conditions of limited space.
For a loader crane, the critical parameters are the load moment and the type of construction.
The load moment is directly related to the reach of the boom and the ability of the truck to carry the load. Therefore, the load moment must be calculated by a professional, which will eliminate the possibility of the vehicle tipping over on its side, because the CMUs do not have their own counterweight systems.
When selecting the optimal configuration of the CMU, it is necessary to take into account the type of design of the device itself. Thus, cable modifications are inferior to hydraulic (folding) analogues in maneuverability and accuracy, but superior in reliability. They are more often used on spacious, large areas, while hydraulic ones are more in demand when working in confined spaces.
When choosing a manipulator, we advise you to take into account all the conditions and select the optimal combination of URAL and KMU chassis.
