Choosing the right transport for the boat is always a search for a balance between cost, reliability and functionality. Trailer boat MZSA Compact It has become a hit with small boats and inflatable boats due to its accessibility and proven design, and has been designed with Russian roads and operating conditions in mind, making it a great choice for weekend trips.
The bulk of small craft owners face a size problem: standard trailers are often too bulky for city parking or a narrow garage. MHSA Compact solves this problem by offering shortened breathing and reduced total length without loss of load capacity. The frame design allows to transport boats up to 4.5-5 meters long, which covers the needs of 90% of anglers and outdoor enthusiasts.
It's important to understand that the cost of buying is not just the price of the trailer itself, but also the cost of maintaining it. Moscow Plant of Special Vehicles (MZSA) uses hot-dip galvanizing of all metal elements, which eliminates corrosion for years to come. Unlike dyed counterparts, which require constant tinting after each season, zinc coating works as an active protection even in the event of mechanical damage.
Technical features and construction of the frame
The foundation of any quality trailer is its frame, and the Compact series uses a square-sectional profile tube that provides high torsional rigidity, which is critical when driving on dirt roads to remote parking lots where the asphalt has long run out. Welded seams They are performed in an automated way, which ensures their uniformity and the absence of weak points, often encountered during manual welding.
The engineers have focused on the depreciation system, which, despite its compact size, can quench significant vibrations to protect the hull from impact, and the chassis is equipped with springs with plastic linings that do not require lubrication or fear water. torsion-axisThe stainless car, found in some versions, provides even smoother running, although it requires a more careful attitude when parking.
The boat's mounting system has also undergone changes for versatility: adjustable beds allow the vessel to be positioned at the right angle, ensuring the correct descent from the water. Inflatable PVC boats often use keel rollers that minimize friction when loading. Steel side in the unfolded state create an additional area for the carriage of cargo, and in the folded do not interfere with maneuvers.
The secret of frame durability
The frame of the trailer MHSA undergoes a double treatment: first hot galvanizing, then, if necessary, powder painting of decorative elements, which creates a barrier that is almost impossible to penetrate the rust in normal use.
The geometry was tailored to keep the center of gravity of the loaded trailer as close as possible to the wheel axis, which reduces the load on the car's farcrow and improves the course stability on the track, even when gusts of side wind or when overtaking trucks. trailer He behaves predictably and does not want to wag.
Overview of popular models of the Compact series
The product line of the plant is quite wide, and it is easy for a beginner to get confused in indexing. MISA 811310The boat is considered the middle ground for boat owners with a length of 3.5-4.2 meters and a carrying capacity of 750 kg, which allows you to take not only the boat, but also a full set of equipment, anchors, fuel tanks and even a small spare engine.
For those who own lighter inflatable boats or kayaks, there is a modification MISA 811301It's even more compact and is often chosen by small car owners, where every kilogram of payload counts, and the design is as light as possible, but without compromising traffic safety.
- 🚤 MIAS 811310.01.2 - Classic model with sides, ideal for combined transport (boat + building materials).
- 🛶 MIH 811310.02.2 - version with elongated beds for heavier boats with a hard bottom and powerful engines.
- 🏍️ MIZ 811300 - a basic platform, which enthusiasts often refine for specific tasks, for example, the installation of a crane beam to lift the engine.
When choosing a specific modification, it is worth considering not only the length of the vessel, but also its weight in running order. Total mass Excessive loading leads to rapid wear of the bearings of the hubs and deformation of the frame, which is especially dangerous at high speeds.
The Benefits of Hot Dip Dip
The water environment is aggressive not only for the hull of the boat, but also for the trailer: constant contact with water, salt (if we are talking about the sea or salt lakes) and reagents from winter roads requires maximum protection of the metal. The hot galvanizing technology used at the MZSA plant involves immersing the finished frame in a bath with molten zinc at a temperature of about 450 degrees Celsius.
This process creates an alloy of iron and zinc on the surface of the steel, which has electrochemical protection, and even if you scratch the frame to the metal, it's not the steel that will rust, but the zinc coating around the scratch, healing the damage, which is a fundamental difference from conventional paint, which, when chipped, immediately opens the way to corrosion.
⚠️ Warning: Despite its high corrosion resistance, after each departure on salt water, it is recommended to wash the trailer with fresh water. The accumulation of salt in hidden cavities and compounds can reduce the effectiveness of protection over time.
The service life of such coverage is calculated for decades. Guarantee against through corrosionThe silk provided by the manufacturer is a direct confirmation of the confidence in the technology, which means that for the owner, there is no need to remove the bed every year, skin the frame and paint it again, saving time and money.
Hot galvanizing increases the service life of the trailer by 3-4 times compared to painted analogues, fully recouping the difference in price for 5-7 years of operation.
Operation and preparation for the season
Before the first outing, a new trailer requires minimal preparation, but checking the main components is never superfluous. First of all, you need to check the pressure in the tires, which must correspond to the values indicated on the sidewall of the tire. Usually for light trailers of MHSA this value is about 2.0-2.2 atmospheres, but it is better to consult the instructions.
The next step is to check the tightening of the wheel nuts. After the first 500 kilometers of mileage, it is recommended to re-stretching the fastener, since the metal tends to slightly "sit" under load, it is also worth lubricating the ball head of the coupling device and checking the operation of the safety cable, which is a mandatory safety element.
☑️ Checklist before the first descent into the water
The contact connectors are often oxidized from moisture, so it is recommended to use a special lubricant for electrical contacts or regularly treat them with WD-40. Retro-reflective elements The catafos must be clean so that your trailer can be seen on the road at night.
To extend the life of bearing units, it is recommended to carry out preventive maintenance once a season (or every 10,000 km). Although many models have closed bearings that do not require lubrication, checking their condition (no backlash and hum) will help to avoid trouble on the way.
Comparison of the specifications of the MHSA models
To make a final decision, it is useful to compare the key parameters of different modifications in one table, which will help you understand which model will best suit your specific tasks and the existing car.
| Parameter | MISA 811301 | MISA 811310 | MISA 811317 |
|---|---|---|---|
| Load capacity | 415 kg | 750 kg | 1050 kg |
| Length of platform | 2960 mm | 3634 mm | 4200 mm |
| Total mass | 750 kg | 750 kg | 1300 kg |
| Type of suspension | Resorbed | Resorbed | Resorbed/Torsion |
| Tyre size | 165/70 R13 | 175/65 R13 | 185/60 R13 |
As you can see from the table, the difference in size and load capacity is significant. 811317 It is already classified as heavier trailers and may require category E in the rights if the total mass of the road train exceeds 3,500 kg. For most cars with a conventional farcop, the best choice is the "golden mean" - the model 811310.
Tire size choices also affect ground clearance and cross-country performance, and the higher wheel is better at overcoming track and rough dirt roads, which is common on wild beaches, but the smaller diameter makes it easier to replace the wheel in the field and allows the use of a standard spare wheel from a passenger car.
Safe towing and storage rules
Safety on the road depends not only on the technical condition of the vehicle, but also on the skills of the driver. MHSA Compact The distance to the car in front of you should be increased by one and a half to two times compared to the movement without a trailer.
The trailer has the ability to cut the trajectory by going into a corner closer than the tractor. When parking in reverse, the steering wheel must be turned in the opposite direction from the desired direction of the trailer - a skill that requires a little training on an empty area.
⚠️ Attention: The speed of the trailer on the country roads should not exceed 90 km/h, even if the trailer technically allows you to go faster. High speed sharply reduces stability and increases the risk of wagging ( yaw) of the trailer.
In winter, when the trailer is not in use, it is better to store it in a dry room or under a canopy. If this is not possible, it is recommended to remove the wheels and store them in a vertical position in the heat so that the rubber does not crack from the frost. The trailer itself should be installed on the stands, removing the load from the springs, although modern materials allow you to store them in a loaded state without losing properties.
Use a breathable trailer case during storage – this will prevent dirt and water from entering the coupling mechanism, keeping the hinge mobility until the next season.
Frequently Asked Questions (FAQ)
Do I need category "E" to drive a car with a trailer MZSA Compact?
For models with a gross mass of up to 750 kg (e.g. MHSA 811310), category "E" is not required, category "B" is sufficient, provided that the total mass of the road train does not exceed 3500 kg. If the total mass of the trailer is higher (e.g. 1050 kg or 1300 kg), you need to look at the vehicle registration certificate: if the column "Permissible mass of the trailer" is a dash or a mass less than the mass of the trailer, category "E" is mandatory.
Can I install a compact braking system on the MHSA?
Factory configuration of models of the series "Compact" usually does not provide for a braking system, since their total weight does not exceed 750 kg, where the brakes are not mandatory by the rules. However, it is technically possible to install brakes (inertial or electric) with the appropriate skills and certification of changes in the traffic police, but economically it is often impractical due to the high cost of work and components.
How to calculate the load on the farcop correctly?
Vertical load on the coupling head (breath) for light trailers of MZSA is usually from 25 to 50 kg in running order. the exact value is specified in the data sheet of the trailer vehicle and in the instructions for the car. Exceeding the permissible load on the car's farcrep is strictly prohibited, this can lead to breakage of the body or the coupling device itself.
Is the MZSA Compact suitable for the transportation of a jet ski?
Yes, many Compact models (especially the 811310) are great for jet skis, the width of the platform allows you to accommodate the equipment, and adjustable padding or roller supports (which can be purchased separately) will provide reliable fixation, the main thing is to make sure that the platform length is sufficient for a stable placement of the jet ski.
