Axle repair and maintenance

The axles of semitrailers, trailers and trawls, which are used to transport fairly heavy and bulky goods, are the most vulnerable structural elements.

If the semi-trailer carries about 60-70 tons of cargo, then each pair of wheels should withstand about 10 tons.

It is important to understand that at the time of arrival of heavy self-propelled equipment onto a trawl, the load on individual axles increases to 20-30 tons.

Transportation of goods is often carried out in difficult road conditions, so problems such as axle ruptures, cracks in the steel base, broken threaded joints, deformation of structural elements are not uncommon.
The axis may lose its ideal geometry, which may result in:

• loss of stability on the highway;
• wagging the semi-trailer;
• tearing to a flat path;
• knocks and rattle when cornering and bumps;
• loss of directional longitudinal stability.

For maintenance and repair today the most modern methods are used. Specialists must perform a visual inspection of the structure for visible damage and malfunctions, and then perform a complete diagnosis and testing at special stands.
Wheel pairs are completely disassembled and reassembled with the replacement of worn or damaged elements, electric welding is performed, and turning works are performed.

After all the procedures, reassembly and testing in operating modes are performed.

It is necessary to take into account the place of the defect and the nature of the damage, after which such overhaul procedures for the axles are performed, such as:

• restoration of seats for bearings and other hub components;
• elimination of cracks, chips, fractures of metal by welding;
• restoration of brackets and places of their fastening;
• restoration of bearing journals;
• production and installation of new pins;
• restoration of the hub mechanism;
• restoration or replacement of washers and springs;
• restoration of pivot elements;
• beam maintenance and so on.

All welding works are carried out with subsequent quality control of the seam using an ultrasonic flaw detector. The final alignment of the axes is made on special stands for adjustment and testing.

Please note that when overhauling axles, it is often necessary to perform maintenance on the components and mechanisms closest to them: brake drums, steering levers, shock absorbers, and so on may require replacement and repair.

Timely diagnostics of semitrailers – a way to prevent expensive repairs

Modern models of semi-trailers are quite effective equipment that can provide trouble-free transportation of the heaviest and most complex loads. It stands out for its high reliability and a sufficiently long service life, the most difficult operating conditions. True, the operation of any equipment is always accompanied by breakdowns, which can lead to considerable financial costs. Semi-trailers are not an exception, the downtime of which entails no less expenses than their major repairs. Well, if a breakdown happened on the way, then it can be dangerous for all road users.

Prevent such a development of events can timely diagnosis of semitrailers.

What includes the diagnosis of semi-trailers

In Ukraine, services for qualified diagnostics of semi-trailers are provided by Trans-Auto D, which is engaged in the maintenance of equipment, both of its own production, and other foreign and domestic brands.
Certified specialists of the TAD company perform all types of diagnostics in Ukraine, including testing:

• brake systems of semi-trailers. Including EBS and ABS from WABCO;
• suspension and axles for correct functioning;
• electronic and electrical equipment for trawls;
• pneumatic and hydraulic equipment.

The use of advanced technologies, including computer diagnostics and original testers, allows TAD engineers to detect the slightest malfunctions in the systems under test, which can lead to great troubles. It is the detection of problems at an early stage that allows you to take action in time and avoid a very expensive overhaul.

It is recommended to carry out a complete diagnosis of equipment within the framework of regularly conducted maintenance, which will contribute to the uninterrupted operation of the semi-trailer. In addition, it is worth checking the trawl if any problems are found in its operation, since the operation of a faulty semi-trailer is strictly prohibited.

Always convincing result

Diagnostics and repair of equipment is performed at Trans-Auto D by highly qualified, experienced craftsmen and engineers who regularly undergo training, which allows them to master the most modern systems and options. This ensures the accuracy of diagnostics and guarantees a high result of troubleshooting.
Do not postpone the scheduled maintenance of the semitrailer. At the same time, one should not forget to make a note in the service book about its passage.

Applications for trailers and semi-trailers

Particularly heavy and bulky construction equipment or non-standard cargoes, in the form of energy and industrial equipment, cannot be transported by ordinary truck or main truck. To transport oversized cargo, road trains are used, which include powerful tractors and special low-bed or high-bed semi-trailers. At the same time, their design and operational capabilities may differ, depending on the production tasks that the trucking company solves.

Features of special semi-trailers

There is always an opportunity to purchase trailers of the most popular types in Ukraine in the company Trans-Auto D, which offers its own production equipment:

• ultralight platforms, the low mass of which fully complies with the latest requirements of the law relating to axial loads;
• classic low loader models, whose maximum load capacity can reach 120 tons. This technique can also be used to install drilling equipment on a mobile chassis;
• semi-trailers with telescopic sliding platforms, suitable for transporting long loads. Reliability of their transformation is provided by pneumatic locks;
• ladders with detachable gander. This design feature greatly simplifies the loading of complex, self-propelled vehicles.
  For example, an excavator, pipelayer or combine;
• platforms with a low loading height. This technique has convenient ramps for loading self-propelled equipment, niches for its wheels and retractable expanders;
• off-road semitrailers. They have high ground clearance and enhanced air suspension, and are also equipped with special tires.
  Effective on summer terrain and in winter;
• universal onboard platforms, the variable load capacity of which allows you to carry goods in a wide weight range. Great for transporting long loads and assortment;
• tipper semitrailers designed for transportation of different types of bulk materials. They can be straight or rounded.

Advantages of the TAD technique

The semitrailers manufactured in Ukraine by the TAD company stand out:

• excellent maneuverability and controllability;
• reliability of each welded joint;
• high quality coloring;
• well thought out and calculated axial formula;
• using components of reputable global brands;
• an individual approach to the creation of each trailer, to its design and configuration.

The large range of TAD allows you to meet the needs of a manufacturing or transport company of any profile. At the same time, its own service center and trouble-free access to any spare parts allows the manufacturer to take care of the equipment after its sale.
