Many car owners are faced with a situation where a standard roof rack or free space in the luggage compartment is sorely lacking. This may be due to transporting large cargo, building a house, or simply moving. In such cases, it comes to the rescue trailer - a compact and effective solution to expand the capabilities of your vehicle. Unlike full-fledged trailers, rolling trailers do not require separate registration with the traffic police, which makes them incredibly convenient for domestic use.
However, despite the apparent simplicity of the design, the use of this device has its own technical and legal features. Improper loading or disregard for securing rules can lead to serious consequences on the road, including loss of cargo or damage to the vehicle. In this article, we will analyze in detail what a roll-on trailer is, how to choose it, operate it correctly, and how it differs from other types of towed devices.
Design features and operating principle
A rolling trailer is a platform on wheels that does not have its own drawbar in the classical sense. Instead, the front of the load (or the trailer itself, if it is a combination system) rests on the undercarriage platform, while the rear of the trailer is raised off the road. Hitch in this case, it is used to connect the trailer to the car, and the trolley itself only provides support points for the wheels of the attached device. This allows you to turn a semi-trailer into a full-fledged vehicle with minimal effort.
The design of such devices is usually as simplified as possible. The main elements are the frame, axles, wheels, a drawbar for connecting to the vehicle's tow bar and locking mechanisms. It is important to understand that lifting capacity tackle is limited not only by the strength of its frame, but also by the characteristics of your car’s tow bar. Most models are made of steel profiles treated with anti-corrosion compounds, which ensures long service life even in aggressive environmental conditions.
A key safety element is the load securing system. Reliable trailer always equipped with strong clamps or chains that prevent the trailer from moving while driving. The absence of its own braking system on trolleys (unlike heavy trailers) is compensated by the fact that the mass of the transported cargo is distributed between the axles of the trailer and the wheels of the trolley, and braking is carried out by the towing vehicle through the coupling device.
⚠️ Attention: Never exceed the maximum permissible weight specified in the vehicle's passport and in the documents for the vehicle's tow bar. Overload leads to destruction of the frame and loss of vehicle control.
Main types of dolly trailers
The automotive accessories market offers several modifications of tackles, each of which is designed to solve specific problems. Choosing the right model depends on what you plan to transport most often. Making a mistake in choosing the type of design means getting an inconvenient tool that will gather dust in the garage.
The first and most common type is universal tackles for transportation of other wheeled vehicles. They are ideal for transporting single trailers, motorcycle trailers or even small cars (as a tow dolly). Such models often have an adjustable track width, which allows them to be adapted to different types of wheels.
The second type is specialized platforms for transportation ATVs and snowmobiles. They can be made in the form of a single structure or collapsible modules. The third type is trolleys for transporting long loads, such as boats, boats or construction materials, where only the rear part of the load is required to be supported, while the front part is attached to the towbar.
- 🚗 Trolley: Designed for towing one car by another, leaning on the front or rear wheels.
- 🏍️ Moto-ride: Compact platform with holders for fixing motorcycle or ATV wheels.
- ⚓ Boat option: Equipped with rollers or keel blocks for convenient loading of water equipment on land.
- 🏗️ Construction tackle: Reinforced frame with sides for transporting bulk or large materials.
Selection criteria: what to look for
Buying a tackle is an investment that should pay off in convenience and safety. When choosing a device, first look at lifting capacity. It should be generous in relation to the weight of the heaviest cargo that you plan to transport. If your ATV weighs 300 kg, buying a 250 kg bike is pointless and dangerous.
The second important parameter is the type of wheel mounting. The mechanism must provide rigid fixation, eliminating any backlash. Pay attention to the quality of the welds and the thickness of the metal. A thin-walled profile can deform at the first serious load. It is also worth checking the availability reflective elements and the possibility of installing side lights, since traffic regulations require the designation of the dimensions of the cargo being transported.
Equally important is compatibility with your vehicle. Make sure that the height of the hitch (tow ball) matches the height of the drawbar. If the difference is too great, you may need to replace the ball or use adapters, which is not always safe. Also check that you have a spare tire if your model includes one, as finding the right tires for your specific runaway tires can be difficult while on the road.
When choosing a boat mount, make sure that the mounts or rollers will not damage the hull of your boat. It is better to choose models with rubber coating or adjustable stops.
| Parameter | Light class | Middle class | Heavy class |
|---|---|---|---|
| Load capacity | up to 300 kg | 300–600 kg | 600–1000 kg |
| Weight without load | 20–40 kg | 50–80 kg | 80–150 kg |
| Wheel type | 4.00-6 | 13 inches (automotive) | 14-15 inches |
| Purpose | Motorcycles, cargo | ATVs, boats | Cars, boats |
Rules for safe operation and loading
Safety on the road directly depends on how correctly you loaded trailer. The center of gravity of the load should be located as low as possible and strictly in the center of the axis of symmetry of the device. Shifting the load to the side can lead to a rollover when turning, and shifting it forward or backward can overload the towbar or unload the front axle of the vehicle.
A visual inspection must be carried out before each departure. Check the tire pressure, the tightness of the wheel nuts and the condition of the fasteners. Pay special attention coupling mechanism: It should snap into place with a distinctive click and be secured with a safety cable or chain. This cable is mandatory - it will hold the roll if the main clutch suddenly opens.
As you move, your driving style must change. The braking distance increases, the dynamics of acceleration and the behavior of the car in corners changes. Avoid sudden maneuvers and sudden braking. When reversing, be extremely careful: the trajectory of the undercarriage differs from the trajectory of a conventional trailer, and there is a high risk of collapsing the structure or damaging the vehicle.
☑️ Check before departure
⚠️ Attention: When transporting wide loads that protrude beyond the dimensions of the roll by more than 40 cm on each side, be sure to install a “Large load” sign and mark the edges of the load with reflectors or flags.
Legal aspects and traffic regulations requirements
One of the main questions that worries owners: is registration required? trailer roll at the traffic police? According to the current legislation of the Russian Federation, trailers weighing up to 750 kg do not require a separate license plate and registration if their technically permissible maximum weight does not exceed the curb weight of the vehicle. Because trolleys typically weigh little and are designed for light loads, they often fall into this category.
However, if the weight of the loaded trailer exceeds 750 kg, or if the total weight of the car and trailer exceeds the permissible maximum weight established by the car manufacturer, then the presence of a category "E" becomes mandatory on a driver's license. Also in this case, the trailer must be registered and have a license plate. Always check the documents for your car (section 4 of the STS - “Permitted maximum vehicle weight”).
Don't forget about lighting equipment. Even if the tackle itself does not require registration, it should not block the lights of the towing vehicle. If the load or structure of the tackle obscures the brake lights or turn signals, you must install an additional light panel with working optics connected to the towbar socket. Lack of lighting means a guaranteed fine and the risk of an accident in the dark.
What happens if there is no category “E” and the weight of the loaded trailer is more than 750 kg?
In this case, the traffic police inspector has every right to issue a fine for driving a vehicle without the appropriate right (part 1 of article 12.7 of the Code of Administrative Offenses of the Russian Federation). The fine ranges from 5 to 15 thousand rubles, and the car can be towed to an impound lot.
Maintenance and storage
To trailer has served you for many years, it needs to be looked after. The main enemy of a metal structure is corrosion. After each trip, especially in winter or off-road, it is recommended to wash the frame and chassis, removing salt and dirt. Periodically, at least once a season, check the condition of the protective coating and, if necessary, touch up chips.
Wheel bearings also require attention. Although many modern models use maintenance-free bearings, play in the wheels is a warning sign. Lubricating the moving parts of the coupling mechanism and locking locks must be done regularly to avoid jamming at the most inopportune moment. Use specialized lubricants that are resistant to water washout.
It is best to store the roller in a dry room, garage or under a canopy. If this is not possible and the device remains outdoors, be sure to use covering material. Prolonged exposure to ultraviolet radiation and precipitation destroys rubber elements (anthers, seals) and accelerates metal corrosion. Proper storage is the key to ensuring that next season you don’t have to do repairs instead of relaxing.
Regular lubrication of the coupling mechanism and checking tire pressure prolongs the life of the dolly trailer and ensures safety on the road.
Frequently asked questions (FAQ)
Is it necessary to register a trailer trailer with the traffic police?
Registration is required only if the gross weight of the trailer with cargo exceeds 750 kg. In most cases, for light tackles used with passenger cars, registration is not required, but it is recommended to carry a device passport (or a copy) with you.
Is it possible to tow a trailer with category "B"?
Yes, you can, if the total permissible maximum weight of the car and trailer does not exceed 3500 kg, and the weight of the trailer does not exceed the weight of the curbed vehicle. If these conditions are violated, a "BE" category will be required.
What is the maximum speed with a roll-up trailer?
According to traffic regulations, when towing a trailer (regardless of its type), the speed outside populated areas should not exceed 90 km/h, on highways - 110 km/h, and in populated areas - 60 km/h.
Do I need a separate MTPL policy for a trailer?
For individuals using trailers for personal use (not for commercial transportation), a separate MTPL policy for the trailer is not required. The car policy covers use with a trailer.
