Technical characteristics of low-loader trawls and platform semi-trailers

What are they regulated by?

Careful preparation prevents mistakes. In this case, the general characteristics of the cargo should be clarified. Self-propelled tracked and wheeled vehicles move to the platform under their own power along inclined ramps. Cranes and hydraulic manipulators are used to load turbines, substations and other products. In the second case, additional free space will be needed. The transportation itself is regulated by several documents:

• By Order of the Ministry of Transport of the Russian Federation No. 7 of January 12, 2014;
• Traffic rules;
• Decree of the Government of the Russian Federation No. 272 ​​of April 15, 2011

In accordance with current regulations, non-standard loads are those with dimensions of 255 x 400 x 2000 (Width x Height x Length in cm) and a weight of 38 tons.

The rules set limits on the permissible axle load, taking into account maintaining the integrity of the roadway.

Advantages

The advantages of special trailers include:

• reliability due to the manufacture of all components from especially strong structural steel;
• the ability to easily enter and exit the trawl for any transported equipment;
• stability of cargo during transportation over any distance due to high-quality fixing devices;
• good handling and maneuverability;
• modular and sliding telescopic models allow you to place cargo of any non-standard dimensions;
• universal connecting elements are suitable for joining tractors of any model with cargo trawls;
• Convenient ladders or ramps make loading simple and safe.

Thanks to the large number of axles, the loads from the transported goods are distributed evenly on the loading platform without causing damage to the roadway.

Transportation Features

You should also pay attention to the following important nuances:

• A special permit must be obtained for a vehicle to travel on public roads if its total weight is more than 44 tons.
• Parts of the cargo protruding beyond the contour of the transport platform are marked with rectangular signs with diagonal stripes of white and red.
• To ensure safety at night, light reflectors are installed.
• The load is secured so as to prevent it from moving during transportation. It should not interfere with the driver while driving the tractor, or cover the license plate, lighting and signaling devices.
• If the Length x Width of the vehicle is large (24–30 x 3.5-4 m, respectively), the use of a special vehicle is mandatory. It is equipped with a flashing orange light. It follows in front of the tractor to warn road users and pedestrians about the movement of oversized cargo.
• If the width exceeds 400 cm, a traffic police vehicle is additionally added to the column.
• Transportation of goods by trawl is carried out at a speed of no more than 60 km/h with a reduction to 15 km/h on bridge structures.

Registration of transportation

Standard rules apply to limit noise and emission standards. The route is approved by the territorial road department. The application indicates the loading/unloading addresses, expected timing, loading height and wheel configuration of the trawl.

Additionally you will need the following documents:

• general diagram of the vehicle along with the load installed on the platform;
• registration documents for special equipment (tractor and semi-trailer);
• a copy of the permit if international category transportation is carried out;
• a receipt confirming payment of the state fee.

The processing time ranges from 3 to 30 working days. Documents are submitted in person, sent by mail, or use the standard tools of the corresponding section of the State Services portal. The kit is assigned an identification number upon registration. According to current legislation, the period for issuing a permit/refusal is limited to 15 days. However, there is no indication of liability for violation of deadlines. You are not allowed to change the agreed route yourself.

Where can I buy

Buying a low bed semi-trailer.

Improved marketing and a widespread dealer sales network provides semi-trailers to choose from in any region of the Russian Federation.

The Internet is facilitating even greater distribution of sales offers.

Manufacturers offer customers not only in-demand products and favorable discounts of up to 25% upon purchase, but also guaranteed service for the products they sell.

Specifications

The following summary table shows the parameters of trawls for transporting heavy cargo:

This data is provided as an example. When choosing a trawl for transporting special equipment (other heavy and large-sized cargo), check the actual parameters.

Trawls are also divided based on the platform’s carrying capacity into:

• light, designed to transport cargo weighing less than 50 tons;
• medium ones, with the help of which you can relocate heavier things (their load capacity is limited to 200 tons);
• heavyweight ones are designed for non-format transportation with a weight of more than 200 tons.

There is no point in using a heavy platform to move a minimum load, but heavy equipment cannot be transported on a trawl not designed for this purpose.

For what cargo is it used?

Low-bed trailers are suitable for heavy loads for various purposes. Reliable fastening to the surface is ensured, thereby ensuring safety along the entire route.

Trawls are used to transport the following cargo:

• industrial equipment requiring crane loading;
• containers;
• pipes;
• trailers and cabins;
• non-standard equipment with a large weight and little ability to move independently - combines, crawler tractors.

Manufacturers produce super-heavy-weight platforms that are designed to transport specific cargo of non-standard sizes. These include technological structures, ships and individual parts.

Technical features

It is also necessary to take into account the following features of different types of semi-trailers and their equipment.
The straight jib of a semi-trailer is used as a platform for placing components, spare parts, and other relatively small related cargo. Inclined ramps and detachable structures are also used to organize the entry of equipment.

As the weight of the semi-trailer increases, the load on the coupling device increases. This should be taken into account when choosing the right car. In some situations, the off-road properties of a tractor will come in handy.

Trawls for transporting oversized cargo are equipped with rings and other additional elements. Chains, belts, and other fastening devices are attached to them. Some models are equipped with expanders that increase the usable area of ​​the transport area.

In addition to conventional ones, semi-trailers are equipped with steering axles (steering angle - from 15 to 30 degrees). Mechanisms with hydraulic drives are also used. Such devices improve maneuverability and controllability in difficult driving situations. They reduce tire wear and turning radius.

Air suspension is installed not only to effectively compensate for shock loads when driving on uneven road surfaces. In an appropriate design, this system is used to adjust ground clearance during loading and unloading, and in other situations.

All types of trawls for transporting oversized cargo are equipped with a double braking system. Working drum mechanisms are installed on all wheels. Parking brake on 1–2 axles. Its spring accumulators maintain functionality without connection to a pneumatic system or other external energy sources.

Low loader semi-trailer design

Features of equipment with a low frame include the presence of a reinforced chassis. Suspension is most often pneumatic or hydraulic. The main dimensions of a low-frame trawl are the same as for a high-frame trawl - but the loading height does not exceed 900 mm. There are devices for independent entry of equipment - ramps. The number of axles corresponds to the load capacity and dimensions of the low loader.

The advantages of models with reduced height are:

• loading wheeled vehicles under its own power, which allows you to do without a crane;
• high load capacity;
• low height, allowing higher loads to be transported through tunnels, under bridges and overpasses;
• low center of gravity and higher road stability.

Despite many advantages, this type of trawl also has disadvantages. In particular, low ground clearance and, as a result, low cross-country ability. Due to the dimensions of low-loader trawls, cargo transportation over rough terrain is difficult.

Also, it is worth noting the impossibility of transporting small-piece goods and cargo sensitive to environmental influences.

Optional equipment

Modern trailers improve the performance characteristics of semi-trailers using ABS and EBS. These systems reduce braking distances and help maintain a given trajectory in difficult road conditions. They increase tread life. When supplemented with appropriate sensors, operational monitoring of pressure in the brake system/tires is provided, and operational data on the use of the semi-trailer is recorded in the electronic memory.

The rapid movement of large heavy ladders into transport and loading states is ensured by hydraulic drives. If there is no necessary exit on the tractor, you can use a special autonomous trawl for transporting oversized cargo. Such models are equipped with a separate hydraulic station, which is installed on the jib. Power supply is from a battery pack. For recharging, you can use a standard car generator.

To solve certain practical problems, the following additions will be useful:

• electric/hydraulic winch;
• retractable supports;
• folding racks;
• steel sides;
• stoppers and special fastenings for transporting containers;
• removable awning.

Special platforms

Low bed trawls

The most popular option for moving problematic cargo.

One of the main parameters important when selecting a suitable vehicle is the height of the transport platform. Based on this feature, trawls are divided into:

• high-frame (with a distance from the ground of more than 1 m);
• low-frame (with a separation from the ground or road surface of less than 1 m (from 0.6 m to 0.9 m);
• with a reduced platform height (from 0.3 m to 0.5) m.

The latter are optimal if you need to route a load of considerable height under potential road obstacles. Low-bed is perfect for loads with a height of no more than 3 m, although their weight can be significant.

Telescopic trawls

Such devices for cargo transportation are also called sliding devices. They can have from one to several platforms designed to accommodate long, irregular cargo. The maximum size of special equipment transported on telescopic trawls reaches 40 m. The most common type is a 3-axle “Bracket” that can transport a load up to 13 m long, weighing up to 35 tons.

Trawl - what kind of equipment is it?

What is a car trawl - it is a vehicle that is a trailer or semi-trailer with a special platform. They are designed for the transportation of equipment, machinery, large industrial elements, electric generators, construction trailers and even houses.

The trawl can accommodate transported cargo with a width of more than 2.6 m and a height of up to 4 meters or more. In the case of wheeled or tracked vehicles, loading and unloading operations can be carried out without the use of lifting machines. Using ramps (gangways, ladders), a bulldozer or road roller independently drives onto the platform.

Cost calculation and additional features

The cost of trawl services for the transportation of oversized cargo varies significantly in different regions. For an accurate comparison, you should clarify the real capabilities of the carrier, the state of the fleet, and warranty contractual obligations. With comprehensive services, a specialized company performs all the necessary work, from obtaining permits to unloading at the desired address with the preparation of acceptance documents.

They control the movement of cargo in real time using GPS sensors. Operational information can be displayed on the screen of a PC, smartphone, or other mobile device. For convenience, we use specialized software.

Price

Trawls are specially adapted for movement on Russian roads. They are highly maneuverable and economical. European additional components improve and extend service life. The cost of trawls starts from 1,000,000 rubles. and the price depends on the load capacity, modifications, configurations and manufacturer.

Selling a low-frame truck on the secondary market has become much more profitable, because companies have appeared that buy equipment on the Internet. This includes a sliding semi-trailer designed for transporting large and oversized cargo.

Semi-trailer rentals are also easy to find online using photos. For example: the base price for renting a Renault semi-trailer starts from 1,000 rubles. at one o'clock.
