The installation of modern equipment makes it possible to ensure constant air exchange in the chamber, the necessary speed and stability of the air flow, the required temperature level, eliminate “dead zones” and perform active drying. In addition, the powerful lighting of the camera prevents the appearance of dark areas and glare, which also contributes to accuracy and high quality painting.
The new complex is located in the immediate vicinity of the chamber, in which shot blasting of the structure and preliminary preparation of its surface for painting are performed. This provides a quick and most efficient performance of paint work.
The equipment used, as well as the surface preparation and painting technology used by TAD, fully complies with the requirements of the leading manufacturers of paints and varnishes used in transport engineering, which many of them have already been able to evaluate. However, more important is the fact that the painting quality of trailers and semi-trailers TAD will meet the high expectations of numerous customers of the company in Ukraine, which it can satisfy.
Ukrainian production and transport company Trans-Auto-D is a manufacturer of special trawls for transportation of oversized cargo. The model range of semi-trailers manufactured under the TAD brand allows you to satisfy any needs of a particular car company engaged in the transportation of specific goods, agricultural machinery, and industry. But, first of all, it is worth getting acquainted with the main types of trawls for transporting oversized goods.
By design, all trawls for oversized transportation are divided into low loaders and high frame models. Most of the designed and manufactured semi-trailers are represented by low loader models. The very low location of the loading platform allows you to reduce the center of gravity of the transported large-sized industrial equipment, construction or road vehicles. It can be turbines, transformers, excavators, graders, rollers and so on.
However, the small clearance does not allow the use of low loader trailers on rough terrain, country and dirt roads. In this case, a high-frame construction with increased ground clearance is used, which can have a reinforced suspension, all-terrain high-profile rubber and a brake system in a frost-resistant design.
All low- and high-loam structures can be produced:
In addition, each type of this special equipment is distinguished by some design features that simplify the transportation of oversized items.
In the initial version, traditional trailers for oversized goods were created for loading bulk industrial equipment using cranes. But, with an increase in capacity and, accordingly, the mass of agricultural and construction equipment, the need arose for its transportation over considerable distances. The independent movement of wheeled tractors or combines, given the misuse of the suspension and engine, it was difficult to call an economically viable event. Therefore, they began to equip the semi-trailers with folding ladders having a hydraulic or mechanical drive, which greatly simplified the loading of self-propelled vehicles.
The real revolution in the evolutionary development of low-frame platforms was the appearance in 1953 of rotatable (steered) axles for oversized semi-trailers created by Nooteboom from the Netherlands.
It was the classic rear-entry scheme that was used in the Trailer models, endowed with a low frame, Jumbo low loader trailers and Mega high loader semi-trailers, manufactured under the TAD brand.
In the process of production of semi-trailers, constant quality control is carried out, including complete flaw detection of critical components.
If the ramp of the traditional trawl can become an insurmountable obstacle for many types of vehicles, the semitrailer with a quickly detachable tractor, a cut-off gander and a system for lowering the level of the front of the platform allows you to load heavy and bulky equipment in a limited space of construction sites without problems. It is low-loader trailers with a race in front that can be successfully used to transport most types of construction tracked and heavy wheeled vehicles.
In the catalog of the Trans-Auto-D production and transportation company, such semi-trailers are presented by Classic and TUR models capable of transporting goods weighing from 20 to 70 tons.
It should be noted that with the unchanged length of the cargo platform of the traditional trawl, its capabilities when transporting oversized cargoes can be significantly limited. Therefore, if a trucking company serves several construction and manufacturing companies, it is forced to maintain several low loader semi-trailers of different lengths. The solution can be the acquisition of a trawl with a sliding platform, capable of replacing several different-sized models.
The telescopic platform can be extended, with a fixed pitch, to a very considerable length. Fixing the section in the extended state is provided by reliable pneumatic locks. The length of the platform can be changed to the size of indivisible goods, thus preventing their axial displacements during transportation. In addition to long structures, on a fully extended platform, you can transport several units of equipment at once, or, for example, a couple of modular cabins.
The company Trans-Auto-D produces high-profile telescopic trailers, Telescop models, which can be extended from 20 to 56 meters, carrying, at the same time, cargo weighing up to 60 tons.
Strong, competent and high-quality coupling of a road train is ensured by a proven and reliable connection of its two main elements – a truck tractor and a semi-trailer. Hitching and uncoupling are the two most important procedures that are carried out before starting and ending work, as well as when changing a semitrailer.
These procedures must be performed by an experienced professional who has undergone the necessary instruction and has all the necessary skills and knowledge, including theory and practice.
If the hitch or uncoupling is not performed correctly, problems such as:
The safety and reliability of the coupling and uncoupling of semi-trailers and tractors is ensured by strict compliance with all requirements, norms and standards. Only in this case, it is possible to guarantee the delivery of goods from point A to point B without any incidents.
To perform the coupling procedure, the driver or his partner must be guided by special instructions and documentation that contain the following information:
Employees at such events should receive appropriate training. They read the instructions and documentation, and then sign in the corresponding document.
All operations related to the operation, repair and maintenance of freight transport devices are performed by persons who have reached the age of 18 and are trained in safe work procedures. A prerequisite is an introductory, initial or repeated briefing.
Hitching and uncoupling are important procedures that require attention and concentration of the performer. Gloves, protective overalls, special shoes and other personal protective equipment are required. In addition, you will need to strictly follow all the steps and steps.
Any activities should begin with a health assessment:
If you find any problems and malfunctions, you should immediately notify the responsible person and proceed with their elimination (carry out repairs or maintenance of the chassis, brake system, steering, light signaling, and so on).
Before hitching / uncoupling, put the tractor and semitrailer on a flat surface. In this case, the longitudinal axis on them must coincide. The semitrailer is braked by a parking brake, antiretractable stops are placed under its wheels. The drawbar without supporting springs must be mounted on a special support.
All connecting hoses, the wiring system are checked (all wires must be removed and secured), the sides of the semitrailer are closed and fixed.
The tractor moves in reverse to the semitrailer, while making sure that there are no outsiders in the danger zone. It is located between the tractor and trailer only after putting the tractor on the parking brake and turning off the engine. The gearshift lever is in the “neutral” position.
The procedure includes:
Hitching and uncoupling is ideally carried out by two people, however, in special situations, when there are no other options, this procedure can be performed by only one driver.
It is very important to conduct an assessment of its condition immediately before the departure of the road train. It is necessary to check the air pressure, oil pressure, the sound and light signals. Also checked the operation of washers, braking systems, electrics. Must have a first aid kit and a fire extinguisher.
It is necessary to assess the condition of the wheels and the tread, to check the reliability of the fifth wheel coupling. Do not forget to clean and wipe the dirt of headlights, lights and turn signals.
The uncoupling procedure is performed in the reverse order. To do this, the tractor and semitrailer are exposed on a suitable flat platform, after which the following measures are carried out:
Remember that only competent and correct execution of hitching and uncoupling operations ensures the safety and durability of any vehicle. All routine procedures must be carried out accurately and correctly; you cannot skip a single paragraph of the instruction.
It is imperative to carry out regular technical inspections with the replacement of working fluids and worn elements. Such procedures should be performed “automatically” – over time, they will become a habit and will not cause any difficulties.
