Modern agro-industrial farms and private farms are quite large in total area. The volume of production is very large, so without highly efficient agricultural machinery for land cultivation can not do.
TAD offers the latest series of semi-trailers for the needs of the agro-industrial sector. They differ in the increased passability in the conditions of domestic off-road, the maximum reliability, simplicity in service and operation.
Specialized trawls are used to transport oversized cargo, as well as large agricultural machinery and equipment. Heavy tracked tractors, combines for harvesting grain, corn, beets, potatoes and other equipment are unprofitable and impractical to distill to new locations on their own.
In addition to destroying the existing pavement of public roads, the equipment is subject to additional wear. Operating life is reduced, fuel is consumed, and travel time is hours or even days.
For this reason, it is best to use low-frame trawls to move such equipment. TAD series of semi-trailers, which have proven themselves in the agricultural sector, are always available at TAD:
Modern industry is constantly releasing new models of equipment, so TAD is always trying to meet the “new standards”, increased size and other features of transported self-propelled equipment.
Some models of large combine harvesters, as well as new multi-row drills, are difficult to transport on most existing trawls. For this reason, we offer brand new semi-trailers from the Classic and TUR series.
The main difficulty for the combine is the height of the ramp on the platform to a height of about a meter. Thus the combine has the height that creates certain difficulties at transportation under bridges, for example. The new models of trawls have been specially understated for convenience and reliability of transportation.
Three-axle trawls of new species have almost halved (up to half a meter) loading height. They are also equipped with expanders that allow you to expand the floor of the platform up to 3.5 m. The frame can carry more than 30 tons of payload, and its length of 12.5 meters allows you to work with any modern agricultural machinery.
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.
