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.
