Transportation of a passenger car on its own is not always possible or expedient: wear of the components, fuel consumption and travel time affect. It is in such situations that specialized equipment, such as trailer. This solution allows you to deliver the vehicle to the destination without a single kilometer on the odometer, preserving its resource and presentation.
The modern market offers many options for platforms, from lightweight single-axis models to heavy biaxial designs. The choice of the appropriate option depends on the weight of the cargo transported, the type of tractor and the frequency of use of the equipment. It is important to understand that the wrong equipment can be a source of serious problems on the road.
In this article we will discuss in detail the technical characteristics, legal aspects and subtleties of the operation of trucks. You will learn how to calculate the permissible load, what documents will be required for legal transportation and what to pay attention to when buying used equipment.
Design features and types of platforms
The basis of any truck is a frame that experiences enormous dynamic loads. Most often used pendant or a reinforced cross-sectional tube. It is from the quality of welds and the thickness of the metal that the durability of the entire structure depends. Cheap models often sin using thin-walled metal, which over time deforms under the weight of the car.
By type of loading, the platforms are divided into ramps and using lifting mechanisms. The classic version is the folding. rampartThe car is driven by a car or is driven by a winch. More complex systems can have a hydraulic or electric platform tilt drive, making it much easier to load low-end sports cars.
A critical element is the type of lodging. For standard passenger cars used wheel-bed with rubber inserts that prevent slipping. They lock the wheels in the right position. For racing or low cars, bottom fixation systems can be used, but this is already specialized equipment.
⚠️ Note: When buying a trailer, be sure to check the availability of a certificate of conformity (OTTS). Without this document, registration in the traffic police is impossible, and operation on public roads is equated to driving without numbers.
Technical specifications and load capacity calculation
The main parameter you need to look at is full-body trailer. It consists of the mass of the empty trailer and the mass of the payload. For passenger cars, models with a total weight of up to 750 kg or up to 3500 kg are most often used. Exceeding these limits requires the presence of category “E” in the driving license.
Particular attention should be paid to the distribution of weight. The centre of gravity of the loaded vehicle shall be strictly above the axis or axial block of the trailer. Shifting the load forward overloads the tractor's breather and coupling device, and shifting back causes dangerous swinging ("wagging") at high speeds.
How does the length of the base affect sustainability?
The long base of the trailer provides better stability when driving, but increases the turning radius. Shorter models are more maneuverable, but prone to yaw if the car on the platform is not fixed perfectly in the center.
The braking system also plays a key role. If the gross mass of the vehicle exceeds 750 kg, the presence of coast down brakes or inertia brakes is a mandatory safety requirement. Otherwise, the brake distance of the train increases significantly, which can lead to an emergency.
- 🚛 Load capacity The maximum weight of the vehicle that can take the platform without damaging the frame.
- ⚖️ Breathing load vertical force, usually not exceeding 50-75 kg for passenger couplings.
- 📏 Platform dimensions - length and width should allow you to place the car with a margin for fixing the wheels.
Towing rules and requirements for the tractor
Towing a heavy trailer-carrier is stress for the engine and transmission of the tractor. Not every crossover or sedan is able to safely move a load weighing 2 tons. It is necessary to consider torque engine and gear ratios of the transmission. Diesel units in this regard are preferable to gasoline analogues.
The most important element is farcake. It must be certified for the model of your car and have a permissible vertical and horizontal load exceeding the weight of the equipped trailer. The use of non-standard or Chinese analogues of questionable quality is strictly prohibited.
When the train moves, its dynamic characteristics change. The braking distance increases, the overall corridor is lengthened when cornering and the maximum speed decreases. It is recommended not to exceed speed on the road. 90 km/h, even if traffic rules allow more, since at high speeds there is a high risk of loss of stability.
Legal aspects and documents in the Russian Federation
Operation of the truck requires a full package of documents. First of all, the trailer itself must be registered with the traffic police and have its own plate-plate. The owner receives a TTS on the trailer and undergoes regular technical inspection if the weight exceeds 3,500 kg (for individuals up to 3.5 tons of TO is not yet necessary, but the condition must be in good working order).
If you plan to transport other people’s cars for money, the situation changes dramatically. Such activities are classified as freight transportation and require a license, travel lists and the corresponding status of an individual entrepreneur or LLC. Private transportation of your car or a friend's car (free of charge) does not require licensing.
| Type of mass | Up to 750 kg | Up to 3,500 kg | Over 3,500 kg |
|---|---|---|---|
| Category of rights | B | BE | BE (or C1E) |
| Registration with the traffic police | Required. | Required. | Required. |
| Technical inspection | Don't need it. | Not necessary (for individuals) | Mandatory. |
| Tachograph | Don't need it. | Don't need it. | Mandatory. |
⚠️ Attention: Carriage with a running engine ("in tow") and transportation on a truck are different things from the point of view of traffic rules. On the road carrier, the car is considered a cargo, so the driver of the evacuated car may not have the rights of the appropriate category.
The process of loading and fixing the car
Correct fixation is the key to safe delivery. Use chains or cables thrown over the roof, categorically impossible - it will damage the LCP and the geometry of the body. Special attachments are used for fastening strap-string with a ratchet mechanism and hooks that cling to suspension elements or special eyelets.
The loading process begins with the vehicle being installed strictly in the center of the platform. The wheels must fall into the deepening of the beds. After that, the parking brake of the car is turned on, and the gearbox is transferred to the parking mode (or to the transmission for the manual transmission).
☑️ Auto-fixing algorithm
The tension of the belts should be uniform. If you pull one side, the car can stand on a diagonal, which will create a dangerous roll. After fixing, it is recommended to rock the car; if it remains stationary relative to the platform, and when rocking the trailer there are no backlashes in the mounts, then you can go on the road.
Use soft loops to pass the belts through the suspension levers if the hooks can scratch the metal. This will keep the parts from damage and prevent the hook from slipping.
Maintenance and care of road vehicles
The trailer-carrier operates in aggressive conditions: dirt, water, reagents and vibration. Regular maintenance will prolong his life. First of all, you need to monitor the condition. bearing-assemblies. Lubrication in the hubs is recommended to change every 10-15 thousand kilometers or once in the season of active operation.
Electrical wiring is the second vulnerable element. The socket and socket contacts on the tractor are often oxidized. Use special lubricants for electrical contacts and check the size and stop lights before each trip. Faulty light alarms are a common cause of fines from traffic police officers.
Rubber elements of pads and shock absorbers also require attention. Rubber eventually dries up and cracks, ceasing to hold the wheel reliably. The shock absorbers lose their properties, and the platform begins to "goat" on irregularities, transmitting shocks to the frame of the car-cargo.
Timely anti-corrosion treatment of the frame and regular check of the tension of bolt joints are the main factors of the longevity of your truck.
Frequently Asked Questions (FAQ)
Do I need a special permit to transport a car on a truck?
For personal purposes (carrying your car or a car of friends without commercial profit), a special permit is not required if the dimensions do not exceed the standard (width 2.55 m, height 4 m, length of the road train up to 20 m). If you are engaged in a commercial evacuation, the rules may vary depending on the region and type of cargo.
Can I tow a car with a car inside on the highway 110 km / h?
According to the traffic rules of the Russian Federation, the maximum speed for cars with a trailer on highways is 90 km/hAnd on the other roads, 70 km/h. Exceeding these standards is dangerous because of the risk of loss of stability of the road train and is fraught with fines.
What to do if the weight of the trailer with the car exceeds 3,500 kg?
In this case, you will definitely need a category. "BE" in your driver's license. If category “B”, the total permissible maximum mass of the vehicle and trailer shall not exceed 3,500 kg and the mass of the trailer shall not exceed the mass of the vehicle in running order.
How to properly store a trailer-carrier in winter?
It is recommended to store the trailer under a canopy or in the garage. If this is not possible, be sure to remove the wheels and keep them warm, and the trailer itself install on the stands (pads) to unload the tires and springs. Electrical wiring is better preserved with silicone lubricant.
