Some categories of agricultural machinery, construction machinery, road construction cranes, rollers, asphalt pavers should not be moved to the place of work on their own. This takes a maximum of time and mostly leads to the destruction of the asphalt-concrete pavement.
In addition, this technique is very large and low speed, which can cause serious congestion on public roads. The best way to move such equipment from point A to point B is to use special low-frame trawls and trailers.
Any self-propelled special equipment differs in both serious dimensions and weight, and inflated center of gravity. This can be a problem when transporting on descents, ascents and entrances in sharp turns.
For maximum safety in the transportation of such goods, any modern low-frame trawl must have the following features:
TAD offers well-proven semi-trailers and trawls of such series as Classic, Jumbo, Mega and Trailer for transportation of heavy special equipment. Each of the models offered to your attention can be completed with various equipment, depending on features of use.
Low-frame semi-trailers and trawls are indispensable when moving special equipment at any distance. Crawler machines, asphalt pavers, road rollers, combines, excavators – this and other equipment move at low speeds, so time in this case becomes a decisive factor.
We should not forget about the motor resource, which is spent in vain when moving special equipment over long distances. That is why heavy low-frame trawls have become a real way out of difficult situations. Today they are successfully used for transportation:
For safe and reliable transportation, trawls are low-frame with a low center of gravity. The maximum load capacity depends on the model and series of the trawl – it is usually about 60 tons. Depending on the size and weight of special equipment, up to 3 units of self-propelled equipment can be driven on one trawl.

When transporting oversized cargo and industrial equipment on a low-bed or high-bed semi-trailer, various dangerous situations arise, and special cargo fasteners are used to avoid overturning or shifting the load on the trawl.
On low loader semi-trailer or a platform during movement, an inertial and gravitational load acts, which depends on the center of gravity of the cargo, its mass and dimensions. When loading the trawl, the technical standards are not always clear and the weight must be calculated taking into account the transverse and longitudinal inertial slip.
So that the load does not move on the platform, it must be securely fixed. Often, to fasten the cargo on a low loader trailer, it is enough to use belts with a loop or direct link. To fasten industrial goods, various equipment, agricultural machinery, you need to use steel chains and cables. For the safety of the transported cargo during acceleration and braking, it is necessary to use cushioning materials that are selected according to the type of cargo, it can be boards or bars. To protect the easily-moving elements of equipment and cargo, you need to use bags.
The task would be more difficult to secure the cargo on a low loader platform on which transporting machinery, equipment, or any other heavy cargo. For transportation of wheeled vehicles such as tractors or combines on the trawl manufactured by Trans-Auto-D, there are wheel recesses in the platform. Also for the exact location of oversized cargo such families of trailers as Classic, Jumbo, Mega, TUR equipped with platform extensions.
• chains made of special steel with tensioning mechanisms;
• anti-slip materials for the platform;
• wheel chocks.
• platform expanders;
When loading, the dimensions and weight of each cargo are taken into account, and for each oversized cargo, a complex calculation of the location of the cargo on the platform is needed. It is considered optimal to install the largest weight in front of twin or built axles. Often, when developing a transportation plan, schemes with weight characteristics in height and length are used. The parameters of the number of axles and load capacity are taken into account when selecting a high-loader or low loader platform, when the question is about choosing a trawl.
Depending on the load force, special universal universal schemes for securing the load on the platform have been developed for fastening chains and belts on a TAD production trawl. When transporting oversized cargo, all trailers are equipped with wheel chocks for the machine and the semi-trailer. Stops hold the “trawl” on uneven terrain or slopes.
When transporting wheeled vehicles, the engine compartment is considered the heaviest part. For the correct location in the area of the rear axles, the rear or front loading of the platform is used. Classic Series trailers are equipped with a detachable front gooseneck. The hydraulic locks on the cylinders allow you to fix the clearance of the front of the trawl in the desired position, which is very convenient when crossing uneven sections of the road and driving under bridges, and lengthening telescopic allows you to correctly position the load and safely transport it to the unloading point.
Even when the load is properly secured, dangerous situations often arise when speeding and braking abruptly. Therefore, the logisticians are faced with the task of developing a transportation route with a minimum of steep descents and ascents. At sharp bends, loads with a high center of gravity can overturn the platform. You also need to move uniformly along the entire route, and the dangerous places on the route require the skill and experience of the driver, you must pass inclines and turns at minimum speed.
What are the main factors that you should pay attention to when choosing a semi-trailer for the needs of your business? In fact, the issue is quite important and relevant for hundreds and thousands of owners of enterprises, fleets and industries.
More importantly: ultimate load capacity or restrictions on use in difficult conditions? There is no doubt the importance of such a parameter as the reliability of the frame platform, for example, as well as increased functionality and versatility.
In addition, if you intend to actively operate low loader semi-trailers, you should pay close attention to such parameters as, for example, the total number of axles and the minimum (maximum) loading height).
What affects the durability and maximum safety of operation of semitrailers? First of all, strength, reliability, durability of steel elements. The frame and its components must have a maximum margin of resistance to the effects of any external factors.
To connect parts, both bolted joints and welding are used. Much also depends on the quality of welding – best when the procedure is carried out in an argon atmosphere.
We are well aware that no matter how heavy the cargo is, the situation is exacerbated by the weight of the semitrailer platform itself. In them, the manufacturer uses special heavy-duty steels, and also with high accuracy calculates the maximum allowable load on each of the main axes, the number of which can be from 3 to 9. This allows you to achieve the maximum load rating with a sufficiently low dead weight of the platform.
One cannot but mention the suspension, the choice of which is critically important. A few years ago it was believed that for the most difficult road conditions in severe weather conditions, it is best to use a mechanical type of suspension.
At the same time, there are exceptions to each rule: our own experience shows that the air suspension is no worse, and in many situations, it better copes with such adversities. Driving a semitrailer with such a suspension is much easier and more comfortable, especially if we are talking about platforms that have high ground clearance and are used on the roads.
Choosing the type of semitrailer, we, first of all, focus on the types of cargo that we are going to transport, as well as on the condition of the road surface in the work area. Important are the climatic features of the area. Typically, for country and paved areas, customers choose a universal semi-trailer.
When you need to transport bulky cargo of large weight, it is worth using a low-bed semi-trailer. It has a very low center of gravity, which avoids tipping over and other problems when transporting oversized cargo (drilling rigs, steel structures, road and construction equipment).
It is important to remember that low frame semi-trailers can only be used on paved or concrete surfaces. Country roads and rain-washed dirt roads are simply not for them. For complicated road conditions, you can use a trawl with a high frame of increased “all-terrain”. In addition to increased ground clearance, you get reinforced brakes and all-terrain wheels.
If you are engaged in agriculture, industry, construction, if you manage a large transport fleet, the issues of choosing the “right” semi-trailer are extremely important. As a rule, high-quality products of foreign factories are prohibitively expensive, and in most cases it is not necessary to talk about normal adaptation of equipment to domestic roads.
Choosing Trans-Auto-D semi-trailers, you get the best ratio of cost and technical characteristics. Moreover, this technique is specially created taking into account our road, climatic and weather realities.
