Semi-trailers, low-frame trawls and platforms, which are designed to transport large and heavy loads, must meet fairly stringent standards and requirements. The key factor is the strength of the frame and the equipment of semi-trailers with all kinds of functional equipment.
The design of any semi-trailer is quite complex. Some mechanisms are actuated by compressed air. These units are part of the pneumatic system, which must be serviced only by qualified specialists.
Trans-Auto-D, a well-known manufacturer of low-frame trawls and semi-trailers, uses a pneumatic system from the well-known European plant WABCO to equip it. The pneumatic system includes a compressor unit that supplies compressed air to the preparation system to clean the mixture from all sorts of contaminants and moisture.
Compressed air is required for the operation of such components and mechanisms of the semi-trailer as:
Pneumatic assemblies and mechanisms, like any other equipment, require regular maintenance and repair. Breakdowns are the result of natural wear of components and parts that operate at high pressures and under intense loads.
What does maintenance include and what maintenance work needs to be done with semi-trailers? Based on the regulations, standards and requirements of technical regulations, the mechanics of any trucking company must perform the following routine procedures:
The dehumidifier cartridge must be replaced at least once a year. Before leaving the route, each driver is obliged to check the operation of the pneumatic system – in particular, the operation of the brakes.
For an experienced driver, there is no difficulty in identifying problems with the operation of the tire. The fault may be due to brake pedal failures, oil leaks from the pipes and the compressor. The characteristic whistling of air from damaged highways also indicates a violation of the efficiency and functionality of the pneumatic system.
Chassis repair may include maintenance or complete replacement of elements such as:
High-quality and professional repair of the pneumatic system, which is performed by TAD specialists, is a guarantee of traffic safety and long-term operation of your vehicle, even with the maximum load of the semi-trailer or trawl.
If you often transport goods weighing about 25 tons, you need a modern solution for reliable and safe transportation. The manufacturer of low-loader semitrailers Trans-Auto-D is ready to bring to your attention several popular models that are characterized by maximum efficiency. One of the most popular today is the TAD Classic 25-2 low loader trawl. The semi-trailer of this model has a minimum dead weight due to the use of special high strength alloys. This ensures that the trawl can be used with maximum payloads. Semi-trailers of this type have a maximum service life in any conditions. They are distinguished by simplicity and ease of maintenance, subject to timely diagnostics and maintenance in the prescribed periods of time. In addition, trawls have a minimal cost of ownership.
The Trans-Auto-D company not only offers high-quality machinery and equipment, but also provides the necessary maintenance. The constant availability of original spare parts in any required volume is a guarantee of quick and timely service and repair. High reliability, proven equipment, ease of use – this is a guarantee of your convenience and comfort when using semitrailers 25 tons from the manufacturer TAD. For each semi-trailer, specialists are ready to offer practical or versatile functionality that will best suit your transport tasks. For example, for those who want to constantly monitor the value of the axle loads, we offer special pressure gauges, with the help of which you can find out the “ton-per-axle” indicator at any time. For high-quality fixation and securing of oversized cargo, we offer special tractor couplings, reliable racks that prevent cargo displacement, lodgements, as well as loops. In addition, your semi-trailer can be additionally equipped with extendable platforms, fittings, side ladders, ganders and other equipment. This will allow the use of low-bed trawls not only for transporting standard equipment, but also for transporting oversized cargo – combines, seeders, bulldozers or even sea containers up to 40 feet long. The presence of an access ladder allows any wheeled or tracked vehicles to enter the trawl independently.
The total cost of a platform is made up of many factors. In particular, the choice of axles plays a role, which can be ordered from any well-known manufacturer of your choice. Each option is always equipped with original spare parts, so maintenance and repairs will always be carried out in a timely manner and without delay. If you need ladders for completing a trawl, the cost will greatly depend on the type, width and material of manufacture of this element. We guarantee the reliability and ease of use of our ladders. In addition, this element also looks very aesthetically pleasing, which is undoubtedly a pleasant additional bonus for any owner of a low loader trawl. To order a semi-trailer trawl with a carrying capacity of 25 tons from the Trans-Auto-D company, call the phone number indicated on the website or leave an online application. Our managers will promptly contact you and answer any questions.
A fully loaded road train, which includes a low-frame trawl, has a curb weight of 60-100 tons. It is difficult to manage such weight, especially at long descents or in difficult road situations.
It is necessary to constantly dampen the inertia of the mass, so the quality of the braking system of semi-trailers are quite serious requirements. It just needs very powerful brakes, the design of which can be quite complex.
Semi-trailers and trawls, which are manufactured at the production facilities of TransAvtoD, are equipped with a modern braking system consisting of several main components. It uses standard drum and pad braking systems, to which a spare pneumatic circuit is additionally connected.
In addition, the system includes brakes for parking and emergencies, is equipped with spring-type energy batteries, as well as modern ABS and EBS electric modules. If the inspection shows the slightest malfunction of any of the above elements, the semi-trailer on the route will not be able to completely eliminate the problem.
What can indicate possible problems and malfunctions associated with problems in the brake system? Experienced drivers will immediately point out several nuances, including:
The main causes of malfunctions and problems in the brake system is irregular maintenance and natural wear of basic elements, components and mechanisms. Overlays, pads, calipers and hubs, as well as pneumatic pipes, electronic units and other components are subject to wear.
For normal operation of equipment it is necessary to carry out regular maintenance, diagnostics, replacement and scheduled repairs. This minimizes the likelihood of brake system failure, which often becomes the main cause of accidents and damage to valuable cargo.
It is important to correctly diagnose the air suspension, as well as the chassis, which may require complete disassembly of individual elements, defects to determine the degree of wear or existing mechanical damage.
The specialists of TAD have extensive experience and have all the necessary tools for high-quality diagnostics and repair of the brake system of a semi-trailer, platform or low-frame trawl.
Quality repairs from professionals may include the replacement of components such as:
Drums and pads are always replaced in pairs on one axis – this is necessary for the simultaneous operation of the brake wheels. Friction linings require replacement when the critical wear mark is reached, which is set by the manufacturer.
At the planned service or repair of brake system the accompanying repair of pneumatic system which you can also order in the service center of the TransAvtoD company can also be required.
