Quite often, situations arise when the car owner would like to change something in his car or trailer platform. Is it possible to remake a car trailer and how much so that there are no questions from the traffic police?
Usually, experienced drivers say this: such updates are allowed by law. vehiclethat do not significantly change the manufacturer's design. Therefore, if you want to raise the sides by 10 centimeters or install a frame for an awning on the platform, paint the body in a fashionable color, then do it quite calmly.
And if you decide that for the further operation of the towed equipment you need to double the carrying capacity and install the second axle, get ready for the fact that you will have to go through a certain number of instances, sit for a considerable time in queues, conduct technical expertise and register changes to the design scheme vehicle. All this, of course, is not the most pleasant pastime.
But it is better than excesses on the road, when you have an urgent trip, they are waiting for you somewhere, but they will not wait for you due to the fact that you are stopped by law enforcement officers, a fine and deprived of the vehicle registration, taken away government number.
Rather than pondering whether it is possible to remake a factory trailer so that it transports twice as much cargo or to make a house on wheels out of an ordinary cart, it is better to immediately buy trailed equipment with the appropriate parameters.
What most often do drivers want to change in their vehicles when they need to decide whether a trailer can be altered?
- To increase the carrying capacity of trailed equipment.
- To make the trailer more reliable and durable.
- Increase the size of the body for transporting long loads or oversized luggage.
- Expand the functionality of the vehicle, for example, install on the platform the equipment necessary to lift the boat out of the water.
- Improve the design of the towed vehicle.
If it's all about design, is it possible to redo light trailer so that it looks more modern and stylish? Here, most likely, no one will forbid you to update, if the basic design remains the same. You can:
- cover the body with a new varnish and paint agent;
- install the latest reflectors and headlights;
- replace the worn-out awning with a new or original plastic cover;
- install LED strips around the perimeter of the body for illumination;
- replace wheels and tires.
Such updates do not change the factory design, do not affect vehicle control, do not affect the stability of the road train, and do not threaten traffic safety. It's just that the trailer looks more modern, it's not forbidden.
What can be modified in a light trailer to increase its durability and reliability?
- You can replace conventional optical equipment with LED optics, it is more economical and does not need to be repaired much longer.
- Provide a frame for a modern awning that will minimize the aggressive effects of weather factors.
- Sheathe additionally the platform bottom and body with plywood.
- Carry out additional anti-corrosion treatment.
Such events, as a rule, do not raise questions from the representatives of the traffic police.
What can be done to enhance the functionality of the trailer?
- install mounting hardware;
- carry out the installation of additional funds: a washstand, storage for tools, a support wheel, if it was not there initially, and so on;
- lengthen the factory drawbar to carry long pipes, logs, fittings and more.
Although it must be understood that a significant increase external dimensions The vehicle cannot remain unnoticed and will interest the traffic police. Also, do not make a full-fledged platform for a boat or yacht out of a flatbed trailer. Too significant alterations are necessary for this, it is better to buy specialized equipment right away.
Increase in lifting capacity, installation of a second axle, brake system, the replacement of the suspension is a major change in the design of the vehicle. Is it possible to alter a factory trailer like this passenger car? Experienced drivers will not advise you to engage in such global tuning. Spend effort, time and money on alterations in the design, and it is not a fact that the final result will be of sufficient quality.
And don't forget about the need technical expertise, registration of technical documents, registration and other paperwork.
The MMZ trailer has been serially produced since 1972. The device is intended for transportation different types cargo and tourist equipment. The basic tractor for this unit is the VAZ-2101 car. Both products have the same components: tires, shock absorbers, bearings. The MMZ trailer can be used in aggregation with other passenger cars of domestic and foreign production, which are equipped with a standard traction coupling.
Device
The considered includes in its design the following parts:
- Frame and drawbar.
- Awning with arches.
- Body.
- Undercarriage.
- Castle.
- Support racks.
- Electrical equipment.
- Signaling.
Frame trailer MMZ made of steel by welding. It consists of a pair of longitudinal beams and three cross members. The side members have a trapezoidal section (50/32/25 mm) and are made of steel. A locking device is welded in the front part of the converging side members. In the middle there are brackets on which the springs of the suspension and shock absorbers are attached hydraulic type... The rear cross member is equipped with bumper and support legs mountings. In addition, the frame has holes for bolting the body.
Characteristics of MMZ trailers
The body part is made of steel by welding. The bottom and sides are made by stamping from sheet steel (0.7 mm). The wheel arches enter the body in the area of \u200b\u200bthe side walls. The floor is covered with a ribbed rubber cape. The upper trims of the sides are equipped with sockets for the installation of awning arches, which are pipes of a certain diameter. The awning itself is made of tarpaulin, fixed on the arches with a special cord, which is threaded through the eyelets located along the edges of the canvas.
The lacing is carried out between the eyelets, thrown onto the strapping hooks, which are welded to the sides. Chassis MMZ trailer consists of the following elements:
- Wheels with VAZ-2101 tires.
- Tubular axle with pins welded at the edges.
- Cross and longitudinal bar.
- Spring suspension mechanism.
- Telescopic hydraulic shock absorbers.
- Shock absorber fixing brackets.
- Rubber buffers.
- Chippers.
Equipment
The MMZ light trailer is equipped with three support posts... They are mounted on a platform to block the suspension springs. The electrical equipment of the fixture is single wire type, powered by an automotive onboard voltage 12 V. This also includes a pair rear lights, license plate light, a set of wires with a plug.
The rear light elements are of a two-chamber type (in the upper compartment there is a single-strand turn signal lamp, and in the lower part there is an analogue with two strands, indicating a brake light and dimensions).
Features:
The front MMZ is equipped with a pair of reflective reflectors of a round configuration and white color scheme. A pair of triangular red reflectors are provided at the back. In 1986, the board began to be made collapsible, new reflectors appeared. Improved variations received a rear-shifted axle, smaller fenders, mud flaps. Later, they began to produce models without bumpers, instead of which there were just two protrusions, options with updated optics and a different combination of reflectors. The frame number is located on the right under the tailgate.
Alteration of the MMZ trailer
Below is one of the ways to modernize the device in question. The essence of tuning is to dismantle the body and replace all the elements to the maximum. Initially, we mount a new lock, then sandblasting and painting the sides. The main process includes the following steps:
- Replacing the rear shock absorber rubber bands with bushings.
- If these elements are suitable for further use, do not show signs of deformation, it is better to leave them, especially if they were made during the Soviet Union.
- Analogs from Oka or Zaporozhets can be supplied as spring mechanisms (if a constant and maximum load is provided). In the second case, you will need to purchase spring ties.
- As rear shock absorbers parts from VAZ-2101, "Moskvich" or "Niva" are suitable.
- Use 12 * 60 mm bolts for fastening.
- Wooden crossbars under the body can be exchanged for metal profiles.
If the tires rub against the springs, use an additional spacer from brake disc VAZ-2101.
Modernization
Trailers for cars, the price of which starts at $ 200 (depending on the state of the "cart"), can be improved in another way. Stages of work:
- Replacing the hitch with a new version.
- Hubs and a handbrake are mounted.
- An additional support on the drawbar can be made from an ordinary jack.
- Next, the headlights are replaced (you can buy new elements or use the lamps in stock, for example, from the VAZ-2108).
- The structure is sheathed with zinc.
- Further alteration of the MMZ trailer consists in the restoration of the suspension. To do this, we replace the hubs with plates from the VAZ-2108 (from a bent beam).
- The frame is reinforced.
- The structure is being painted.
Technical specifications
Performance characteristics of the hitch in question:
- Full weight - 300/450 kg.
- The mass of the transported cargo is 135/285 kg.
- The maximum speed when coupled with a car is 80 km / h.
- Length / width / height - 2.6 / 1.6 / 1.02 m.
- Clearance - 25.8 cm.
- Wheel track - 1.34 m.
- Platform area - 2.12 sq.m.
- The dimensions of the inner part are 1, / 1.5 / 0.38 m.
- Connection - ball type.
Recovery
Repair of the MMZ trailer can be done as follows (the original model practically parted at the seams):
- Reanimation begins with a thorough filling of all cracks by welding. Next, the diagonals are checked, the sides are pulled together with soft rolled wire with further strengthening of the corners. A couple of amplifiers are welded onto the bottom. This operation is due to the fact that in the standard version the bottom is equipped with only one amplifier, which is not enough for full operation. As a result, the metal breaks, the bottom just falls through.
- You can weld a new body bottom from available tools as an additional layer on top of the main element. For this purpose, several pieces of iron with a thickness of 3 mm are quite suitable. To begin with, the segments are welded together, and then with the main coating. For reliability, the entire structure is fixed with bolts with press washers.
- We mount reinforced springs.
After restoration, the MMZ-81024 trailer was subjected to increased loads (transportation of cement, sand, crushed stone). For 4 months of operation - no complaints, even in comparison with the new sample.
Hello, friends! Since a factory trailer can not always fully meet the needs of its owner, many decide on structural changes to the vehicle. All sorts of alteration of the trailer is aimed at achieving those characteristics that will suit you.
But what can be created from it and how much can trailers be modified? Let's talk about this.
Legality of modernization
I will not talk specifically about how to do this or that tuning. Is it possible to change the design at all? This is the first question to be answered.
I will say this. Some changes may not require you to make any adjustments to your documents. But cardinal tuning will potentially become the subject of disputes with road service employees.
Therefore, before converting your ordinary car trailer into a camper or using it as a mobile home, consult the traffic police for advice.
Tuning requires the receipt of appropriate certificates of changes in the design of the vehicle. You will have to go through a number of offices, pay state fees, stand in lines, etc.
Although many simply ignore it. They modernize the trailer as they wish, and on the spot with the traffic police they find out how legal it is and how to get around such bans. If you want to get rid of unnecessary stops on the roads and incomprehensible fines, go through the lengthy but legal procedure for reissuing the trailer. it the best option, in my opinion.
Well, or instead of converting PVC for a boat, immediately buy yourself a trailer designed and certified for just such purposes. Alteration is a troublesome business, although it is always pleasant to watch the results of work done by yourself.
Why is it needed
Indeed, why take and change a ready-made trailer, if initially you were quite satisfied with its layout or design ?! The question is purely personal and depends on the individual needs of the car owner.
Let's take some good trailers as an example:
- MMZ 81021;
- Scythian;
- VMZ;
- KMZ 8119;
- MZSA;
- Kurgan trailer, etc.
Good vehicles with enviable for many manufacturers technical characteristics... But if suddenly there is a need to use them for transporting boats or for transporting a motorcycle, then they will not be able to cope with such tasks.
Yes, for trips to their dachas and loading several bags of potatoes harvested in the garden, any standard trailers are perfect. But I want something different and more.
I would highlight several main goals that car owners pursue when deciding to change a trailer:
- improve functionality;
- to increase the indicators of carrying capacity;
- change in the better side reliability parameters;
- modernize purely appearance TS.
Now let's go over each of the points separately and decide what can be done in a given situation with our factory standard trailer vehicle.
Reliability
If you are worried about the issue of reliability, then it is better to immediately take for yourself a more expensive and resistant to all loads and influences trailer. Then you don't have to think about whether he can last 5-10 years.
To reduce the wear rate, that is, to increase the reliability of your car, truck or boat trailer, you can:
- make the skin of the body and bottom of the trailer using ordinary plywood;
- change the standard optics to LED, which lasts longer and less loads the car's electrical network;
- apply an anti-corrosion agent to the body;
- treat the body with high quality paint;
- put an awning (we talked about it separately here in this article).
The option with replacing the hubs, upgrading the suspension and other improvements is possible. The transition of the Pchelka trailer to springs with a standard torsion bar is very popular. Good for reliability, performance characteristics and the behavior of the trailer on the road of different quality. So it's worth considering.
Functionality
Many are more interested in the functional side of the trailer, that is, its ability to provide various additional features.
Various options are available:
Everything here is limited only by your imagination, needs and real opportunities... It is clear that it will not work to make a whole huge mobile home out of a small cheap trailer.
Yes, boat upgrades cargo trailer - this is a more complex process, because you have to create a frame, sides, install an awning with your own hands. It is easier to make a boat out of a cargo boat, because all unnecessary structures are removed and the corresponding limiters and fasteners are mounted. And that's it, the vehicle for transporting the boat is ready.
There are many examples of photos and videos where craftsmen slightly changed the design of caravans, or turned them into a real work of art. There is always something to rely on, where to get examples and inspiration.
Lifting capacity
If you need to transport goods weighing up to 1.3 tons, then it is enough to have an ordinary single-axle trailer.
But sometimes it is required to increase the carrying capacity, for which one more axle is added. From uniaxial we get biaxial. A good decision if it justifies itself from the standpoint of active exploitation.
Get ready to queue up and do the paperwork. Such a conversion into a two-axle vehicle requires re-registration of the trailer with the traffic police. Otherwise, fines cannot be avoided, and even more serious consequences of illegal alterations.
Appearance
The owner does not always need to change its technical and functional characteristics in a trailer. But the standard appearance is depressing, which suggests an idea to change something from an aesthetic point of view.
We turn on imagination and get to work. The most common ones are:
- installation of new optics;
- installation of original reflectors;
- body painting;
- modernization of beautiful protection;
- replacement of the awning;
- perimeter installation lED strips for backlighting;
- replacement of disks and tires.
