Choosing a reliable water vehicle is often more challenging than buying the vessel itself. The market offers many options, but it is not easy to find a reliable water vehicle. trailer The owner of a PVC boat or metal boat should understand that the quality of the frame and chassis depends not only on the safety of the cargo, but also on the safety of traffic on the highway.
Moscow Special Vehicles Plant has been supplying versatile solutions adapted to Russian roads for many years, and unlike handicrafts or expensive imported products, its products combine functionality and maintainability. It is important to consider not only the dimensions of your vessel, but also the vehicle’s load capacity and the specifications of trailer storage in winter.
In this article, we will discuss the technical details of the various modifications so that you can make an informed decision. hot-dipping It's critical to durability, and how to properly prepare the trailer for the first ride, and a competent approach to the choice of tooling will avoid costly frame repairs in the future.
Why MCSA trailers are popular among water engines
The main advantage of the MZSA products is the use of hot-dip In constant contact with water, especially salty water, or simply high humidity when stored, ordinary paint quickly loses its properties. Zinc coating creates a barrier that protects steel even when the surface is mechanically damaged, preventing rust from developing on Years.
Another strong argument in favor of choosing this brand is modular design. While cheap analogues often use welded units that cannot be disassembled without a Bulgarian, it uses a bolt connection of the main elements, which allows the owner to replace the damaged beam, the side or element breathed, just by buying a new part in the store. Repairability It is a crucial factor for those who plan to actively operate equipment away from service centers.
When buying a used trailer MZSA be sure to check the presence of factory stamps on the frame and the compliance of the VIN number in the documents, as the popularity of the brand generates many fakes and stolen copies.
It is also worth noting the wide network of dealers and the availability of spare parts: you can find bearings, winch cables or flashlights for MZSA in almost any city in Russia, which is not the case for many specialized brands, which makes the operation of a boat trailer predictable and does not depend on long expectations for the delivery of components from abroad.
Overview of popular models for PVC and boats
The manufacturer's line is quite extensive, but for boaters, the most interesting are several specific modifications, each of which is sharpened for a certain class of floating vehicles and has its own design features. 810117, 810118 and 810119 This will help to avoid errors when ordering.
The 810117 is considered a "people's" model, most commonly purchased for inflatable boats up to 4.5 meters long, with a minimum mass of its own, allowing it to be towed even by small cars. However, its carrying capacity is limited, so it may not be suitable for heavy aluminum boats with motor and equipment.
For more serious vehicles, the 810118 is a reinforced frame and a higher load capacity, and the design has been modified to accommodate the load, and if you're a cantilever-controlled boat or a heavy boat with a powerful motor, this is the version that you should look at, and it provides more stability at high speeds.
The 810119, which is often equipped with padding instead of a keel roller, is ideal for hard-bottomed boats or fiberglass hulls that require precise fixation along the entire length, and the use of padding reduces the risk of damage to the skin when transported on rough roads.
Technical specifications and comparison of modifications
When choosing a trailer for a boat MOSA must rely on dry numbers. the differences in dimensions and loads may seem small on paper, but in real use they determine comfort and safety. Below is a comparative table of the main parameters of popular models.
| Parameter | Model 810117 | Model 810118 | Model 810119 |
|---|---|---|---|
| Load capacity (kg) | 425 | 525 | 525 |
| Platform length (mm) | 3064 | 3924 | 3924 |
| Width (mm) | 1650 | 2034 | 2034 |
| Unladen mass (kg) | ~170 | ~220 | ~230 |
As you can see from the table, the 810117 is significantly narrower and lighter, making it maneuverable but less stable for wide boats. The 810118 and 810119 have similar dimensions, but may differ in the type of support surface. Total mass trailer with cargo should not exceed the technically permissible specified in the vehicle passport (PTS).
When choosing between models, always leave a payload capacity of about 15-20% in case of transporting additional equipment, fuel in the tank or anchor equipment.
It's important to consider the type of suspension. Most MHSA models have spring suspension with rubber bushings that dampen vibrations, a proven solution that doesn't require complex maintenance, unlike pneumatic or torsion systems. However, when fully loaded, the stiffness can increase, which is worth considering when planning routes on broken roads.
Structural features: frame, winch and pawns
The heart of any trailer is a frame, which is made of hot-dip steel in MHSA products, and is worth paying special attention to the breather design. Many models use a V-shaped breather, which provides better course stability when reversing and at high speeds.
The winch is the mechanism that takes over the main loads when loading. Standard equipment often includes a mechanical swab with a cable. cable The synthetic version is safer for the hands when cliffed and does not rust, but the steel version is more durable when in contact with sharp edges, the condition of the cable is recommended and the gearbox mechanism is lubricated.
⚠️ Attention! Never leave the winch under load for a long time (for example, in a parking lot), this leads to the pulling of the cable and loss of elasticity of the springs of the mechanism.
The support surface can be made in the form of rollers or beds. Roller guides make it easier to load the boat onto the water, allowing the vessel to slip easily. Lodges provide a tighter fit of the hull, which is critical for long cargo and thin-bottomed boats. The combined version (keel roller in the nose and pawns on the sides) is often the best solution.
Nuances of the pawns
When installing padding supports, it is important to ensure that they are at the same level, and even a few centimeters of distortion can lead to deformation of the boat hull during long transportation along the highway.
Preparation for the first season and tuning
After buying a new trailer, many owners believe that you can immediately go. However, practice shows that initial preparation significantly prolongs the life of the product. First of all, you need to check the tightening of all bolt joints. When transporting, vibration can weaken the fastener, so it is recommended to walk the key through all the nodes.
The next step is lubrication. Despite the factory lubrication in the hubs, many experienced boaters recommend checking its availability and quality. Bearings prefer to use specialized lubricants that are resistant to water washing. It is also worth lubricating the lock loops breathed and the winch mechanism.
☑️ Checklist of trailer preparation for the season
Tuning of the MZSA trailer often boils down to installing additional accessories, brackets for the transport of additional equipment, boxes for storing anchors and equipment, and a backup wheel are popular. support-wheel on the breather (if it is not provided with the basic equipment) greatly simplifies maneuvering in the parking lot without the help of a tractor.
LED optics are not superfluous, instead of standard incandescent bulbs, LED lights use less energy, are not afraid of vibration and light up instantly, which improves safety on the road, and they are less likely to fail due to water intrusion, because they have better leakage.
Maintenance and storage during winter
Proper storage of the trailer in winter is the key to its longevity. Despite the zinc coating, it is not recommended to leave the vehicle in the open with accumulated salt and dirt. Before putting it for winter storage, the trailer must be thoroughly washed, paying attention to the hidden cavities of the frame.
Tires should be protected from UV and ozone, and it is recommended to use special covers or simply cover them with a dense fabric, the pressure in the tires should be reduced slightly, but not completely deflated, to avoid deformation of the cord. The optimal storage option is suspended or mounted on stands, which excludes contact of rubber with the ground.
⚠️ Warning: Do not store a trailer with an installed battery (if there is an electric winch) without removing the terminals. In winter, the battery can run out of power and freeze, causing the plates to collapse and no longer be used.
If the trailer is stored outside, be sure to use an awning or protective cover, this will protect the pawns and fasteners from icing and aggressive effects of precipitation, regularly check the condition of the parking brake, if it is provided by the design, and lubricate the cables.
You can use silicone spray lubricant to preserve metal surfaces in the winter, and it creates a water-repellent film and prevents moving parts from freezing.
Frequently Asked Questions (FAQ)
Do I need to register the MZSA trailer in the traffic police?
Yes, trailers with a gross mass of more than 750 kg are subject to mandatory registration with the traffic police and require a separate license plate. If the weight is less, registration is not required, but the documents (PTS and sales contract) must be with you during the trip.
What category of rights are needed for towing?
Category B rights are sufficient for driving a vehicle with a trailer of category B if the permissible maximum mass of the trailer does not exceed 750 kg or if it exceeds 750 kg but the combined mass of the vehicle and trailer does not exceed 3,500 kg. Otherwise category E will be required.
Can I carry a motorcycle or quad bike on the trailer?
Technically, this is possible if the total weight of the equipment does not exceed the load capacity of the trailer. However, for ATVs and motorcycles, it is more convenient to use specialized platforms with rolling stops, since the keel roller of the boat trailer is not designed for wheeled vehicles.
How often should the bearings of the hubs be lubricated?
The manufacturer recommends lubrication of bearings every 10,000 km or once a year, whichever comes first. When active in water (frequent descents and ascents), it is better to reduce the service interval to 5,000 km.
