For a beginner, the question of the correct name of a shipping vehicle may seem trivial, but it is the accuracy of terminology that often determines success when searching for parts or legal registration. You can hear many names in everyday life: someone says “cart”, someone “platform”, and experienced boat owners use the term boat-trailerUnderstanding the difference between these concepts is critical, because not only is loading convenient, but also road safety, depending on the type of construction.
From a legal and technical point of view, the most correct and common name is the trailer plainly trailerThe term comes from an international classification and refers to a non-motorized vehicle designed to carry goods, in this case - a small vessel. However, in the Russian segment, especially in the context of motorsport and special equipment, the word "lafét" is often found, which has its historical roots and specific applications.
In this article, we will discuss in detail how different types of transport vehicles differ, why it is important to distinguish between different types of transport vehicles. monoaxial and biaxial The options, and also consider the key nodes to look for when buying. GIME It will ensure the safety of your boat during long distance transport.
Main terminology: trailer, carriage or cart?
When the driver asks in the store what is the name boat-carrier, he often expects to hear one particular word, but reality is richer. The basic and most universal name is the boat trailer, which means a full-fledged vehicle with a frame, a breather, wheels and lighting devices, which meets the requirements of traffic rules. trailer is the official name in the PTS documents and registration certificates.
The word “lafet” is more commonly used in the professional environment or when describing specialized devices for lifting and lowering heavy equipment, such as yachts or jet skis, with winches. Lafet is often associated with more massive structures that have reinforced frames and complex fixation mechanisms. At the same time, in everyday life, people often refer to any device for transporting “carts”, which is an oversimplification, but not quite technically true for road versions.
⚠️ Note: When applying for documents at the traffic police or when buying insurance, use the term "trailer" or "trailer". Use of the word "troller" can lead to confusion in the classification of the vehicle and errors in the CTP policy.
The designs are often the basis for the differences in names, and if you see a lightweight structure that can be towed by a B-class car, it's a design. trailerIf you have a massive platform with hydraulics to lift a boat out of the water, it's specialized. skid-liftUnderstanding this gradation will help you find the right parts or accessories in the supplier catalogs faster.
Design features of boat trailers
The interior of a trailer determines its reliability and durability, and the basis of any quality product is a frame, which is most often made from a profiled pipe or channel. The key element of protection against corrosion is the coating: it can be hot galvanizing or high-quality powder paint. Hot galvanizing is considered the gold standard for water technology, as it provides maximum protection against salt water and aggressive reagents.
The most important part is the chassis, which includes hubs, braking system (for heavy trailers), and of course wheels. Boat trailers often use wheels with low profiles and special caps to protect the bearings from water. breathed - the front part of the frame, which connects to the car porch through the coupling device.
- 🛡️ Whistle: The mechanism for tightening the boat to the lodgings can be manual or electric.
- ⚓ Nasal emphasis: adjustable element that takes on the load from the forehead of the boat.
- 💡 Lighting devices: A mandatory element for legal movement on public roads.
Special attention should be paid to the support system of the hull of the boat, these can be classic keel rollers, which make it easy to drag the boat into the water, or stationary laying-pieceThe choice between rollers and paddings depends on the type of bottom of your boat and the operating conditions.
Classification by load capacity and axles
Choosing the right trailer depends on the weight of your boat, and all models are divided into single-axle and biaxial. Uniaxial trailers They are designed for lightweight PVC boats, small aluminum boats and jet skis, and are maneuverable, easy to operate and do not require additional permissions to tow, if the total mass does not exceed 750 kg.
For heavier boats, the length of which exceeds 5-6 meters, and the mass is closer to a ton or higher, are necessary. biaxial The presence of a second axle significantly increases the stability of the train on the road, reduces the risk of swaying the tail and allows the load to be distributed to the road surface.
| Type of trailer | Maximum load (approximately) | For what boats? | Features |
|---|---|---|---|
| Uniaxial | 750 kg | PVC, small aluminium | Light, maneuverable. |
| Biaxial | 750 to 3000 kg | Boats, boats with cabins | High stability, brakes. |
| Special project | over 3000 kg | Yachts, ferries | Requires a special category of rights |
When choosing, consider not only the weight of the boat itself, but also the mass of the engine, fuel in the tank and additional equipment. Safety margin is never superfluous. If the weight of your boat is 600 kg, it is better to take a trailer with a maximum permissible weight of 750 kg than risk overload, which can lead to breakage. spring or hubs.
Manufactured materials: combating corrosion
Water and metal are dangerous combinations, so the issue of materials for a boat trailer is edged. The main options are two: steel with protective coating and aluminum. Steel trailers are cheaper to manufacture and buy, but require constant maintenance. Even high-quality powder paint can crack from a stone impact, opening the way for rust. Hot galvanizing This problem is solved in part by creating a sacrificial layer, but it is not permanent.
Aluminum trailers are premium. Aluminum doesn't rust in the conventional sense; it oxidizes to form a strong film that protects the metal from further destruction, and they're much lighter than steel, allowing heavier boats to be towed by lower-traction vehicles. aluminum-alloy The complexity of welding makes the final product significantly more expensive.
And the little things that we need to remember about it are the fasteners, the bearings, the winch cables, all of which have to be made of stainless materials or have reliable protection. Using conventional ferrous metal for bolts on a boat trailer is like a sentence for the owner: in a season, they will be impossible to unscrew without a Bulgarian.
- 🧪 Zinc: The best protection for steel, but is afraid of mechanical damage.
- ✨ Aluminum: It's a perpetual material, but expensive and less durable to twist.
- 🎨 Powder paint: The budget option requires regular updates.
⚠️ Warning: Never leave an aluminum trailer in contact with copper or brass parts in salt water without insulation. The resulting galvanic vapor will provoke accelerated electrochemical corrosion of aluminum.
Legal aspects and requirements of GIMS
Operation of the boat trailer on public roads is regulated by traffic rules, and registration and admission to navigation - rules GIMEIt is important to understand that the trailer is a separate vehicle. If its total weight exceeds 750 kg, it is subject to mandatory registration with the traffic police, receives its own license plates and requires a separate CTP policy (or entering into the tractor policy, if insurance conditions allow it).
If the total permissible maximum mass of the vehicle and trailer does not exceed 3,500 kg, the usual category "B" is sufficient. Exceeding this limit will require category "E" (BE), Violation of these rules can lead to serious fines and evacuation of the vehicle to the penalty Park.
Separately, it is worth mentioning the requirements for lighting devices. All turn signals, stops and dimensions on the trailer must work in sync with the car. The absence or malfunction of lighting devices is one of the most common reasons for stopping traffic controllers. In addition, the boat on the trailer should not overlap the license plate of the car, and if it covers - you need to install an additional number on the back side of the boat or use a special ramp.
☑️ Pre-departure checks
Service and preparation for the season
The boat trailer, like any other technical device, requires regular maintenance, and the season dictates its rules: after each release, especially in the salt water, you must thoroughly wash the chassis and frame with fresh water, which washes away salt, sand and dirt, which are the main enemies of metal and bearings.
Check the status of the hub bearings regularly. To do this, the wheel must be crouched and wobbled vertically and horizontally. Luft or rotating hums indicate the need to replace the lubricant or the bearings themselves. Many modern hubs are equipped with a system. Easy Lube, allowing you to add lubricant without disassembling the unit, which greatly simplifies maintenance.
Don't forget the winch and the cable. The cable should be rust-free and the winch mechanism should be lubricated. Before a long stand for the winter, it is recommended to treat metal surfaces with preservative lubrication, and the wheels should be removed or raised on the stands to reduce the load on the tires.
Frequently Asked Questions (FAQ)
Do I need to register a trailer for a boat in the traffic police?
Registration in the traffic police is mandatory if the total weight of the trailer (own weight + weight of the cargo) exceeds 750 kg. Trailers of lower weight do not need to register, but they still require a vehicle passport (PTS) when buying.
Can I carry other cargoes on the boat trailer?
Technically, if size and weight allow, but lozenges or rollers can damage the cargo, and the absence of boards makes it impossible to transport bulk materials, and it may raise questions for inspectors if the cargo will be out of size.
What speed is allowed when towing a boat?
According to traffic rules of the Russian Federation, when towing a trailer, the speed of movement on highways should not exceed 90 km / h, on other roads - 70 km / h Exceeding speed is dangerous because of the risk of uncontrolled pumping of the trailer.
What if there is no PTS on the old trailer?
Without the PTS, you can not register a trailer or register it, you can try to restore documents through the traffic police archives if the trailer was previously registered, or look for a seller who can provide a duplicate. Otherwise, it will be extremely difficult to legalize the "iron" and easier to hand it over to scrap metal.
Is Category E required for a light trailer?
Category "BE" is not required if the permissible maximum mass of the trailer is not more than 750 kg, OR if it is more than 750 kg, but the total permissible maximum mass of the vehicle and trailer does not exceed 3500 kg.
