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.
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.
Such equipment for transportation of oversized and heavy loads is selected according to several parameters, including:
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.
The main advantages of transportation platforms include:
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.
Semi-trailers with a capacity of 80 tons can be used to solve the widest range of tasks. The main purpose is transportation of heavy and oversized drilling equipment, heavy excavators, asphalt pavers, diesel ship installations, large industrial machines, rectification columns and other cargoes.
Especially for the transportation of such goods, which differ in large size and weight, the company TransAvtoD has developed and offers its customers low-frame trawls from the line of Jumbo semi-trailers.
Among the features and technical characteristics of the semi-trailer of this series are:
Trawls of this series are completed with axes, pneumatic and hydraulic systems, electronic blocks from known foreign manufacturers.
If the trawl is not used to transport cargo, several axles can be raised when it moves – this saves fuel and increases the life of idle wheels.
The trawl with a loading capacity of 80 tons is additionally completed with accessories and equipment necessary for the decision of this or that task. These can be ramps with manual installation or automatic departure, curved geese, allowing self-propelled vehicles to drive on the trawl on their own. With the help of special platform wideners, its floor width can be optionally increased to 320 cm.
As a rule, platforms with low and high frames are used by specialized enterprises that are engaged in oversized and heavy cargo transportation.
Among the regular customers of the TAD company there are a lot of enterprises, factories and production, whose field of activity relates to such industries as:
These buyers simply need low loader trailers and semi-trailers, which are ideal for transporting both oversized equipment and industrial equipment, spare parts, temporary wagons for workers and so on.
Heavy construction and agricultural machinery cannot move under its own power on public roads, so the only way to quickly deliver it to the place of work is low-loader trawls.
When choosing, you should take into account a number of important points and nuances from the specialists of the TAD company.
Criteria for selecting equipment for transportation
For almost any transport company that is engaged in transportation, the main points in the selection of platforms and trawls remain:
Modern trawls from TransAvtoD are not inferior to well-known foreign counterparts in terms of performance, reliability, quality and functionality. Moreover, their cost is significantly cheaper. A good leader will always prefer to purchase such equipment from a direct manufacturer, because there is no need to pay for the services of intermediaries. At the same time, you can always order non-standard versions, taking into account the peculiarities and specifics of your business.
The maximum weight of the transported cargo is determined by the design features of the platform, its dimensions, the materials from which it is made, and the number of axles.
Today, consumer demand for semi-trailers and trailers with reduced axle loads has increased to the maximum. This allows you to get around some of the restrictions by using them on public roads. Long equipment and equipment are best transported on models of the Jumbo series, which can be extended to carry several vehicles, for example.
Among the products of TransAutoD, each customer will always be able to choose the required platform or trawl model at the most affordable cost.
Low frame trawl design and parameters
Experts recommend paying attention to the following parameters that affect the reliability and durability of the equipment:
The strength of the frame element is ensured by using high quality structural alloys and steels. At the same time, an important point is the quality of the welded work and the absence of defects.
Well-known foreign manufacturers of trawls and platforms have not used spring suspension for a long time. Trans-Auto-D products are manufactured only with pneumatic or hydraulic type hydraulics, which guarantees excellent controllability in the most difficult conditions.
When assembling models of trawls of popular series, Trans-Auto-D uses components from only proven world manufacturers (SAF, Gigant, BPW, Wabco, Tridec, and so on).
In addition, you can always order additional equipment for the purchased trawl or semitrailer, which is necessary for solving certain tasks. It can be:
Service maintenance
When operating trawls with low and high frames, attention must be paid to timely maintenance and repairs. The TransAvtoD company has its own service center, which allows it to serve customers, to offer original spare parts at the most affordable prices.
