Buy a semi-trailer (trawl) for transportation up to 50 tons

Platforms and trawls with a carrying capacity of 50 tons are classified as medium semi-trailers. Scope of application – transportation of various goods, equipment for the needs of industry, heavy machinery and special equipment.

Similar vehicles are also used to transport agricultural machinery (combines, tractors, seeders, sprayers, fertilizer carriers). Effective when working with heavy construction and road construction equipment. They are used for the transportation of finished metal structures, elements of bridges, rolled metal and other goods.

Features and technical parameters

Semi-trailers of this class can have a carrying capacity ranging from 45 to 55 tons, depending on the model, equipment and modifications. They have from three to four axles and are equipped with mechanical or pneumatic suspensions. The semi-trailer weighs from 14 to 17 tons.

The TransAvtoD company offers semitrailers of 50 tons in several main categories:

  • Classic is the most affordable option in basic equipment and standard equipment, which can be used for a variety of purposes.
  • Jumbo – semi-trailers with a sliding platform mechanism, which can be increased in length up to 20 meters when it is necessary to transport special cargo.

If necessary, at the request of the customer, we are ready to complete any trawls presented to your attention with additional equipment and equipment. These can be ladders, ramps, tool boxes, platform extenders, and so on.

When transporting and moving oversized, heavy and non-standard goods, different types of vehicles and platforms are used.
This is quite normal, as each load has its own characteristics and characteristics, ranging from weight and length and ending with the possibility of self-loading on the platform on its own.

Existing types of cargo platforms are able to meet the demands and needs of any customer, so in the fleet of the well-known company TransAvtoD, which deals with oversized transportation, you will always choose the right option for your cargo.

One such vehicle is розсувний трал – a semi-trailer that has the ability to “self-extend”. If necessary, you can always increase the length of the platform from 20 to 56 meters!

As with other vehicles, this type of trailer is suitable for certain uses and loads:

  • bridge supports;
  • reinforced concrete structures;
  • pipe rolling;
  • wind vanes of generators;
  • rowing shafts of ships and so on.

Loads that are too long for other types of platforms can be conveniently loaded and transported with a similar towed telescopic trailer towed by a tractor.

What is a sliding trawl

The retractable trailer configuration has a special design that has been developed and adapted for the safe transport of ultra-long loads on the roadway. The sliding trawl allows you to efficiently receive loads, the length of which can be a real problem for other platforms.

The mechanism of the trailer of this type may include both front and rear chassis, located in a telescopic connection, where each chassis can be supported by separate wheels and axles assembled. They can be tilted in parallel in a compressed state of the mechanism.

 

The main components of the trailer are, among others, the power unit, the goose, the wheels, the support device, the electric frame system, the hydraulic suspension, the brake system, the ladder and the hydraulic system. All these elements are vital for the normal operation and functional operation of elongated trailers.

Features of a design

Please note that there are two main types of telescopic trawls:

  • increase in length;
  • increase in width.

Longitudinal-sliding trailers are most in demand, used to transport very long loads, such as tanks, wind turbine blades and so on.

To accept these loads, the trailer is extended in the longitudinal direction. When it does not carry any load, it must be adjusted to the shortest length. However, its application and use must be based on established local laws and driving safety regulations.

The traditional telescopic trailer configuration has a fixed frame and an additional frame that can be connected to a fixed one. The second frame provides sliding contact with the fixed frame to provide the desired longitudinal elongation.

This means that the free frame can be moved relative to the fixed frame in order to lengthen or shorten the trailer. The movable frame is usually located in the rear of the tractor. This free-moving trailer consists of a set of wheels and axles firmly attached to it. Fastening of cargo is rigidly carried out to a motionless frame.

Semi-trailers for transportation of excavators

Any heavy construction equipment, which is equipped with a crawler or wheel drive and is intended for earthworks, must be delivered to construction sites by special semi-trailers – low-frame trawls.
Moving excavators or bulldozers on your own is impractical and not economically justified.
Their speed is too low, fuel consumption when driving independently is too high. In addition, this reduces the engine life of the engine, and the road surface can be significantly damaged.

Transportation of excavators and bulldozers by low-frame trawls

What are the main nuances in the transportation of heavy earthmoving equipment by trawls? First of all, it is necessary to consider non-standard dimensions of the equipment, and also rather serious weight of the excavator or the bulldozer. For example, such wheeled excavators as JCB, “Komatsu”, “Hitachi”, which belong to the category of medium-weight equipment, have an equipped weight of at least 22 tons.

The light class of caterpillar equipment is not so “light” at all: the weight with the hinged equipment makes not less than 24 tons. If we talk about heavy machinery in the class of crawler equipment, individual models of bulldozers and excavators have an operating weight of up to 50 tons or more.

Standard semi-trailers are not suitable for transporting such equipment, so the only alternative is low-frame trawls from TAD. Such platforms are suitable for transporting almost any oversized and heavy machinery and equipment, with certain rules and regulations (speed limits, the use of escort cars, light signals, and so on).

To transport such non-standard goods, it is necessary to consider and create an ideal route that takes into account many factors. Narrow city streets with heavy traffic should be avoided, bridges and overpasses should be checked for compliance with the requirements for maximum weight and height.

Usually, heavy oversized vehicles are transported on low-frame trawls with special police escort. If the equipment has dimensions that exceed the established norms, it is necessary to dismantle buckets, booms and other attachments. They are transported either on the same trawl or on a separate semi-trailer.

Excavators and bulldozers usually drive on low-frame trawls on their own. If necessary, winches and cranes can be used to tighten the equipment.

Trans-Auto-D semi-trailers that can be used

Such equipment for transportation of oversized and heavy loads is selected according to several parameters, including:

  • maximum equipped weight of equipment;
  • length, width and height of the excavator or bulldozer;
  • type of drive (on wheels or on caterpillars).

Heavy-duty wheeled vehicles should be transported on low-frame platforms with a “broken” type frame, which are part of the Classic series manufactured by “TAD”. Such trawls have a low level in the central part of the floor of the platform, which is located near the drive axles. This allows you to stabilize the load, reducing its center of gravity.

If it is necessary to transport tracked equipment that belongs to the class of heavy equipment, it is advisable to use Jumbo series trawls. They have a maximum load capacity, which makes it possible to transport goods equipped with a weight of up to 65 tons.

Note the special design of the platform, which has a loading height of about half a meter. This allows you to use ramps and ladders for self-entry to the trawl of tracked vehicles.

Advantages of using TransAvtoD trawls

The main advantages of transportation platforms include:

  • reliability of a design;
  • high-strength frames;
  • use of structural special steels;
  • high quality of welding works;
  • reasonable price;
  • complete set of trawls with foreign spare parts;
  • the ability to expand the functionality of the equipment with additional options.

You can pick up and buy similar low-frame trawls both in a basic option, and to order an individual complete set. We will listen to your wishes and comments, changing the typical options “for you”.

Please note that TransAvtoD provides technical and service services, offering original spare parts at the most affordable prices.
