Transporting a boat to the descent site is always a stress test for the owner, especially if we are talking about heavy aluminum boats or large PVC boats with powerful engines. boat-trailerThe right platform will not only keep your boat safe, but also keep other road users safe.
The Russian small-car trailer factory offers a wide range of models, each tailored to specific boating tasks. From lightweight options for inflatable boats to reinforced versions with a braking system for heavy boats, the range allows you to find a solution for almost any budget. In this article, we will discuss technical details so that you can make an informed choice.
It should be noted immediately that MIZNA It's not just a name, it's synonymous with a certain build quality and availability of parts in every region of the country, and owning a trailer that eliminates many of the headaches of finding rare components, but even time-tested solutions have their own specifications that you need to consider before you buy.
Key advantages of MHSA trailers for water technology
The main advantage of the products of this plant is the use of hot galvanizing in the design. It is not just paint, but a full-fledged chemical reaction that creates a protective layer of zinc on the surface of steel. For equipment that is in constant contact with water, salt and aggressive environments, this is a critical parameter that ensures the durability of the frame.
The second important aspect is the modularity of the design. Spring suspensionThe silk-based silk-based silk-based silk-based silk-based silk-based silk-based silk-based silk-based silk-based silk-based silk-based silk-based silk-based silk-based silk-based silk-based silk-block, which is especially important when driving on primers to remote fishing spots, and also allows for home-made repairsilk repairs in the field.
The third factor is adaptability to Russian realities: engineers take into account the specifics of our winters, temperature changes and the quality of the road surface, and unlike many imported analogues, there is no unnecessary complexity in the nodes that could cause problems in the absence of special tools.
- 🛡️ Anti-corrosion protection: Full hot galvanizing of all metal elements of the frame and breathed.
- 🚗 Safe running gear: use of springs and hubs, time-tested and roads.
- 🔧 Repairability: availability of any spare parts and ease of replacement of nodes without complex equipment.
Overview of popular models for different types of vessels
The MZSA product line is divided into several categories according to the total weight and size of the lodging. For owners of light inflatable boats, the 8177 series will be the best choice. These are lightweight single-axle trailers that often do not require registration with the traffic police if their total weight does not exceed 750 kg (although the legislation may change, and this point is worth checking).
For more serious tasks, such as transporting aluminum boats "Crimea", "Ob" or large PVC hard bottom, designed models with the index 81771 and 81772. Load capacity Such platforms allow you to comfortably place a vessel weighing up to 500-600 kg, along with the engine and additional equipment.
If you own a heavy boat, you should look for models with two axles or reinforced single-axle design with a braking system. Such trailers, for example, the 81774 series, are equipped with inertia coast down brakes, which greatly improves safety when driving on the highway and descent on steep slopes.
Hidden feature of lodgings
What many people don't know is that the rubber rollers on the MHSA's lobes can be replaced with plastic keel rollers, which makes it much easier for the boat to self-load, since plastic has a lower friction coefficient than rubber, especially when the boat is heated by the sun.
Technical specifications and load capacity
When choosing a trailer, it is critically important to calculate correctly full-bodyIt consists of the weight of the trailer itself (the curb weight), the weight of the boat, the engine, the fuel in the tank and the additional equipment. An error in the calculations can lead to overload, which can lead to breakage of springs, accelerated wear of the tires and, most importantly, fines from traffic police inspectors.
The table below shows the comparisons of popular models so you can visually measure the difference in parameters. Notice the ground clearance, which is important when venturing on unequipped shores.
| Model trailer | Load capacity (kg) | Lomenement length (mm) | Type of suspension |
|---|---|---|---|
| MISA 817701 | 425 | 4200 | Resorbed |
| MISA 817711 | 525 | 4900 | Resorbed |
| MISA 817721 | 640 | 5200 | Resorbed |
| MISA 817741 | 750 | 5800 | Resorption (enhanced) |
It is important to consider not only the static load, but also the distribution of weight along the axes. breathed It's going to push too hard on the car's farcrow, or it's going to pull the tail of the trailer, and it's going to have a direct impact on the handling of the road train at high speeds.
When buying a trailer, be sure to measure the distance from the transom to the keel of your boat. Other models of the MSSA have a slight difference in the angle of inclination of the padment, which is critical for boats with a short keel pitch.
Features of operation on water and descent
The operation of the MOSA trailer for the boat has its own specifics, which distinguish it from use for the transport of goods. The main enemy here is water, especially salt. Despite the zinc coating, regular contact with an aggressive environment requires attention. After each trip to the sea, it is recommended to thoroughly wash the frame with fresh water.
The process of descent and lifting the boat also requires skill. The winch installed on the front side must be securely secured. The winch cable should be chosen synthetic - it does not rust, does not stretch and is safer for the hands in the event of a cliff than the steel counterpart. Nose accent (keel roller) should be lubricated so that the boat slips easily when submerged.
⚠️ Warning: Never leave a trailer submerged in water for long periods of time, even if it is galvanized. Water inside the spring cavities and pipes can become conserved and cause corrosion from the inside, which is difficult to see visually.
To make the process easier, many owners install additional guides (rolling crabs) on board, which help center the boat when loading windy weather or when there is a current, especially for wide boats that can be blown away by the wind.
- 🌊 Washing: Refrigeration with fresh water after each contact with salt water.
- 🔩 Lubricant: regular maintenance of the bearings of the hubs and the winch mechanism.
- 🛑 Parking brake: use of shoes under wheels when parking on slopes near the water.
Brake system and road safety
The safety of the road train is priority number one: MSSA models with a gross mass of over 750 kg are often equipped with an inertia braking system, the principle of which is simple: when the car is braking, the trailer bumps into the breather by inertia, and this impulse through the cable activates the brake pads on the trailer wheels.
Brakes reduce the braking distance, which is critical when driving on wet roads or in mountainous terrain, but such a system requires proper tuning of the cable and regular checks of the condition of the brake linings. Wearing pads can not only reduce the effectiveness of braking, but also damage the drums.
☑️ Checking the brake system before the season
Keep in mind that driving a heavy trailer with brakes is addictive, and the effect of stretching the train when braking can be felt, and the brake system imposes restrictions on reversing, usually requiring unlocking the hydraulics or using special maneuvers.
Service and extension
And trailer It has been in service for decades, requires minimal but regular maintenance, and the main work is done on the chassis, and it is recommended that the stall bearings be lubricated or changed every 10,000 to 15,000 kilometers, and when used on water, even more often, because water can enter the hubs when hot nodes cool sharply.
The wiring is the second vulnerable element, and despite the waterproof sockets, the contacts oxidize over time, and using contact lubrication and periodically checking the integrity of the insulation of the wires will help you avoid situations where you do not have stop lights on the track. Lighting devices MHSAs are usually standard, making it easier to replace them in case of damage.
⚠️ Warning: When washing a trailer under high pressure, do not direct the jet directly to the hubs of the wheels and electric connectors. Water pressure can push the coils and drive moisture inside the knots, which will lead to their rapid failure.
Also worth paying attention to the condition of rubber elements: bumpers, anthers and the paddings themselves. Rubber eventually loses elasticity and cracks, no longer performing its shock-absorbing function. Timely replacement of penny rubber rubber rubber will save the paint coating of your boat from rubbing to holes.
Regular maintenance of hubs and electrical wiring increases the service life of the trailer by 2-3 times and prevents accidents on the road.
FAQ: Frequently asked questions
Do I need to register the MZSA trailer in the traffic police?
Registration is mandatory if the total weight of the trailer exceeds 750 kg. For lighter models, the presence of registration plates and documents depends on the current traffic rules and the weight of the tractor car itself, but most full-fledged boat trailers still require registration.
Can I carry cargo on the trailer of the MZSA, except for a boat?
Yes, the design allows you to remove the lozenges and use the platform to transport other goods (quad bikes, building materials), if the loading capacity allows, but it is important to securely fasten the load so that it does not move during movement.
What is the maximum speed of the trailer?
According to traffic rules, the speed of a road train (car with a trailer) outside settlements should not exceed 90 km / h, and on highways - 110 km / h (for passenger cars). Exceeding speed can lead to a dangerous effect of "wagging" the trailer.
How to prepare a trailer for winter storage?
You need to thoroughly wash and dry the frame, lubricate the rubbing nodes, ease the tension of the springs (if possible constructively or simply unload), remove the battery from the winch (if there is an electric drive) and store in a dry room or under a reliable awning.
