        I agree . the development there is crazy ate, you say that the standard diameter of the ball is 16. we have a man who hammered one rod by 18 in one piece.
        
        from the zil, I put a big one on a homemade trailer, I had to cut the edges from the crane at the base of the lawn just right

        pressure in the tractor 8 in the trailer 7.5
        
        Added after 5 minutes 59 seconds:
        before the installation of 280 rubber on the tractor, it was still tolerable to drive 70-75. the front tires on the tractor remained at 260. Previously, only the trailer was winding, but now the tractor will not listen
        
        This is most likely the reason. I put the front at 280, and the back 260, the car went more confidently.

        Hello! Guys, please advise how best to apply the brakes on the descent.
        What do we have? Kamaz timber carrier, naturally loaded.
        
        I have two options:
        1. constantly hold the car, not allowing it to accelerate (because then you will not stop
        )
        2. or acceleration-brake, but at the same time it is more difficult and longer to brake.
        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 kinds 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.
        
        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.
        
        Let me put it this way. Some changes may not require you to make any adjustments to your documents. But the 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 motorhome, 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. This is the best option, in my opinion.
        
        Well, or instead of altering 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 observe the results of the work done with your own hands.
        
        Indeed, why take and change a ready-made trailer, if initially you were quite satisfied with its scheme 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:
        
        Good vehicles with technical characteristics enviable for many manufacturers. 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 the reliability parameters for the better;
        
        to modernize purely the appearance of the vehicle.
        
        Now let's go through each of the points separately and decide what can be done in a given situation with our factory standard trailer vehicle.
        
        If you are concerned about the issue of reliability, then it is better to immediately take for yourself a more expensive and more stable 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 the 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 up 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. It has a good effect on the reliability, performance and behavior of the trailer on the road of different quality. So it's worth considering.
        
        Many are more interested in the functional side of the trailer, that is, its ability to provide various additional features.
        
        lengthening the standard drawbar for the transportation of bulky goods;
        
        transition to wheels R13 or more to increase cross-country ability;
        
        installation of auxiliary structures inside the trailer;
        
        Everything here is limited only by your imagination, needs and real possibilities. It is clear that it will not work to make a whole huge mobile home out of a small cheap trailer.
        
        Yes, modernizing a boat into a cargo trailer is a more complicated process, because you have to create a frame, sides, and 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.
        
        If you need to transport goods weighing up to 1.3 tons, then it is enough to have a regular 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, or even more serious consequences of illegal alterations.
        
        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;
        
        installation of LED strips for illumination around the perimeter;
        
        replacement of disks and tires.
        
        The trailer is a huge space for creativity. There are no clear frameworks and restrictions here.
        
        Do not forget that any interference in the structure may become a reason for a traffic police officer to stop you, issue a fine or even a ban on operation until you receive official documents and certificates of re-registration.
        
        Thank you for your attention! Share in the comments your experience of tuning and alteration of caravans and do not forget to tell your friends about us!

        Trailers on the road are subject to frequent shock and vibration loads, so they often break down. The high requirements for the driver of a vehicle with a trailer are mostly justified. And the trailer itself must have strong components, a reliable braking system and be stable on the road.
        
        The most common trailer breakdowns are axle deformation and suspension geometry disturbances. To eliminate these breakdowns, you need to restore the geometry and change the axis. To do this, you need to do a lot of work, namely, cut a new thread, straighten the CAF, weld metal and much more.
        
        Wheel play. This can be due to either loosening of the bolts or nuts that secure the bearing, or the destruction of the bearing itself.
        
        Hitch ball play. The reason is either the wear of the parts of the coupling device and their deformation, or dirt inside the device.
        
        Brake system malfunction. The brake pads may be worn out and need to be replaced.
        
        Excessive brake drum temperature and braking. Dirt may get on the brake cables, or the brake rod may jam.
        
        Faults in electrical wiring:
        
        Lights, brake lights, side lights are off. Broken wire or burned out light bulbs.
        
        Blown fuse in the vehicle. Short circuit in the trailer wiring.
        
        If you are not able to eliminate a malfunction in the electrical equipment yourself, contact a specialist in a car workshop for help.
        
        The most common type of trailer breakdown is axle, half-axle or wheel bearing breakage. Such malfunctions arise due to the influence of dynamic and shock loads that arise during the breakdown of the suspension, due to the inconsistency of the energy intensity of its elastic elements with real load conditions.
        
        Avoiding such breakdowns will allow the presence of a suspension travel reserve with the use of shock absorbers to damp vibrations. In turn, two- and three-axle trailers simply cannot do without compensating devices (anti-roll bars and jet rods).
        
        The presence of a high-quality lock will extend the service life of the trailer and the car. The lock should have a strong body with thick walls, a strong coverage of the towbar ball with breadcrumbs. Its main task is to exclude the disconnection of the trailer, for example, during a sharp turn. The ball of the towbar must be lubricated for the hinges. This grease protects the clutch mechanism from wear.
        
        When choosing a hitch, special attention should be paid to the strength of its frame. Usually it is performed welded. Some manufacturers strive to obtain maximum frame strength at minimal cost, while increasing the cross-section of beams, drawbars, side members. With a decrease in the total weight of the trailer, the loading height increases, the hitch and the locking device are loaded, and the stability of the trailer itself deteriorates. Some unscrupulous manufacturers use bent thin profiles at all, which is not very reliable.
        
        Due to its low cost, the most widespread is the cable drive of brakes. Its disadvantage is that it stretches and wedges in the shells. The cable brake is recommended to be used only for parking, therefore, it should not be used in the service braking systems of the trailer.
        
        Trailers weighing up to 3.5 t are equipped with hydraulic brakes. When the mass of the hitch is over 3.5 tons, a non-inertia braking system is used. If you find one of the above malfunctions, you should fix it as soon as possible to avoid an accident.
        
        The operating conditions of automotive equipment, in particular, cargo semitrailers, on the roads of the former USSR are very significantly different from those in Western Europe, due to which the supporting structures experience significantly higher loads than those for which they are designed.It is also important that a significant part of the fleet of foreign-made semitrailers was purchased after depleting its resource on normal roads. Such conditions lead to the fact that welded and fastening joints of structural elements, and often the metal itself, are often destroyed.
        
        increased dynamic loads when driving on uneven roads;
        
        overloading often practiced by drivers (exceeding the rated carrying capacity);
        
        active influence of aggressive media (salts, etc.), leading to accelerated corrosion;
        
        a number of design features;
        
        metal fatigue.
        
        In addition to these natural causes, deformations and other kinds of damage occur as a result of road accidents, from which, unfortunately, no one is immune.
        
        Most often, the negative impact of operating features leads to the following malfunctions:
        
        breakage of the spring bracket (with mechanical suspension) or trailing arm (with pneumatic);
        
        violation of the geometry of the rear gate portal;
        
        detachment of attachment to the frame of the side struts;
        
        cracks in the frame side members;
        
        destruction of the connection of the traverses with the spar;
        
        through corrosion of steel sides and gate leaves;
        
        deformation of the underride guard.
        
        Taking into account the specifics of the operation, quite often welding work on the repair of semi-trailers is carried out outside specialized technical centers - in small workshops, or at the enterprises' own repair base, often using homemade welding equipment.
        
        For the suspension elements to work correctly, it is necessary not only to restore its attachment to the frame, but to achieve an exact correspondence to the previous position. For these purposes, experienced welders first fix the bracket with M16 bolts, thus ensuring accurate centering of the parts and the necessary pressing force of the bracket to the spar, and only then weld it with a continuous seam.
        
        Often, in order to increase the reliability of the connection, additional reinforcing elements are installed from available materials - a corner or another profile.
        
        Even the highest-quality welding is not able to ensure the reliability of the connection of these elements for a long time, due to which, after strengthening the side and rear struts, additional reinforcement is applied using homemade triangular metal parts - the so-called. "Kerchiefs", which are welded with straight sides to the spar and the strut on one or, more often, on both sides. This uncomplicated design greatly increases its rigidity and successfully withstands the inevitable effects of vibrations.
        
        For the same purposes, "kerchiefs" are often strengthened by the racks even on new semitrailers.
        
        An obvious mistake of inexperienced repairmen with such a malfunction is welding along the crack line. Such a solution is completely ineffective, since the weld is the zone of the highest stress concentration, and it breaks easily even under moderate enough loads.
        
        The correct solution is to cut out a diamond-shaped window in place of the crack and insert a plate of the appropriate shape into it, welded with a continuous seam (the so-called "tambourine"); a change in the stress vector makes it possible to increase the strength of the structure many times over. To strengthen the spar in the area of its restoration, usually a plate, corner or channel is welded on top of the beam on "tacks".

        Passenger car trailers often break down as they are subjected to very heavy loads. Most often these are shock and vibration loads, as well as failure to comply with all operating rules. The most common problem that occurs when using the devices is axial deformation and disruption of the suspension geometry.In this case, you need to replace the axes or restore the geometry. The work to be done in such a case is very great. This is cutting of a fresh thread, straightening of the CAF, metal surfacing and much more.
        
        It happens that malfunctions occur due to a breakdown in electrical equipment. Then they may fail:
        
        headlights;
        
        stop signals;
        
        lanterns;
        
        parking lights;
        
        license plate lighting lamps.
        
        In case of malfunctions of one of the listed dimensions, the probability of an accident increases significantly. Therefore, if any malfunction of the electrical part of the equipment is found, it is necessary to contact a car repair shop.
        
        Nowadays, there are many types of specialized accessories for passenger cars: trailers for ATVs, jet skis, boats and boats, trailers, vans, and so on, each of which needs an individual approach, different equipment and a variety of spare parts to repair. The further work of the carrier depends on these components.
        
        The sides of the device are subjected to very heavy loads. Almost all car dealerships have such a service as onboard installation. They can be plastic, galvanized or some other types. Plastic ones are quite cheap, but their performance is very low, due to the fragility of the main material.
        
        The braking system can also fail. This can cause serious accidents, therefore, if you notice any malfunctions, you should not delay with the repair. Most often, it is enough to replace a spare part. This can be a brake chamber or a tap, a pad, a lining, and so on. If you decide to buy a trailer, remember that with systematic operation, devices with brakes must undergo repair maintenance at least once every six months.
        
        For some drivers, trailers are an indispensable part of the car, so their design must be taken care of properly. Airbrushing applied to the trailer gives it individuality and makes it very interesting. It can be any drawing you like, just a pattern or an abstraction.
        
        It is possible to repress the torsion axles of the carriers, which will increase their reliability and service life. Additional axles can be installed on the structure to improve the lifting capacity. It is also possible to improve the braking system of the standard axle. Installing more lighting fixtures will only improve the situation. A lot of light on the road at night is never superfluous. These can be side lights and taillights.
        
        It would seem that trailers for cars should not bring any additional worries. But this is not at all the case. They require constant care, prevention, and sometimes repair. Prevention is not expensive at all, but the results are worth it.

        Semi-trailers are widely used today for the transportation of goods as part of road trains. Unlike a trailer, it provides an even load distribution on the wheel axles and the fifth wheel of the tractor.
        Maintenance of the trailer and semi-trailer consists in checking the reliability and damping properties of the suspension, the safety of the silent blocks and axles.
        
        Reliable operation of any vehicles, including trailers and semi-trailers, is impossible without high-quality service and diagnostics. You can carry out these works by the service station "TRUCK Center". Since any malfunction can lead to damage to the cargo and cause an accident, timely and high-quality repair of semi-trailers is simply necessary.
        
        A symptom of a semitrailer and trailer malfunction may be:
        
        loss of longitudinal stability;
        
        sideways movement while driving;
        
        moving from side to side;
        
        creaks and noises of the semi-trailer or trailer axle when cornering;
        
        malfunction of the pneumatic braking system, if any;
        
        significant vertical vibrations of an empty trailer in motion, which indicates the need to repair the chassis and suspension, replace shock absorbers.
        
        If the above signs are found, it is necessary to promptly contact the technical center to repair the semitrailer or trailer. To determine the cause of the malfunction, they will diagnose the semitrailer systems, repair and replace worn parts. Since the pneumatic suspension system is common for the trailer and the tractor, sometimes the tractor can be the cause of the malfunction: the control system or other systems.
        
        I bought a bull 2 years ago I did not register this year I decided to put it I didn’t find the frame number of the bulls in 1997 I found the whole frame otter in the net I found the comments that 1999 the number was painted with paint.
        
        Radik (Norene) Azat, look in the feed below, the guy had the same problem, he could not find the number on the frame and was not registered.
        
        Azat (Sonu (Sweety Pie in Hindi)) one guy told me that the number in the middle of the frame under the trim plate on rivets is factory
        
        Azat (Sonu (Sweety Pie in Hindi)) Radik, where?
        
        Radik (Norene) Azat, below for about a month, maybe a little more wrote in the feed, look. One guy from our group was looking for the same number on the frame and could not put it on the register.
        
        Nikolay (Sukhraj) Azat, I have the same problem. There is also no number on the frame. I scrubbed it for a long time and found fragments of paint. An expert immediately came and took pictures of the engine's license plate, the nameplates on the van and the cabin. In general, the examination will cost 2800 rubles, then with the results of the examination it will be necessary to go to the police department, a statement is written there about the loss of the number on the frame. After that, the district police officer, on the basis of an examination, issues a resolution to refuse to initiate a criminal case. With this refusal in the traffic police. And they are already on the basis of this refusal put on record, where the registration certificate indicates that there is no frame number.
        
        Azat (Sonu (Sweety Pie in Hindi)) scrubbed the frame to shine, even fragments of paint are not present the same today in the net I found that as if they had previously duplicated the frame number with paint on bulls. I had gas 4301 1994, it was written with paint when I went through the check I myself was painted with paint here I don’t know the plant is closed, I don’t even know where to call and who doesn’t know. Yesterday I was already stupid in Avito. did not even look at the others full
        
        Azat (Sonu (Sweety Pie in Hindi)) Nikolay, In October 2017, a new technical regulation was adopted on the basis of which EVERYTHING. registration departments of the traffic police refuse CITIZENS to register the replacement of numbered units! This means that any citizen who has acquired a body, cab, frame, engine will not be able to make changes to the title and thereby legalize his repaired car.
        
        The wording of the refusal is as follows:
        
        We inform you that your appeal
        
        on the issue of replacing the numbered unit (body) is considered.

        so that the examination is not the basis for the delivery of registration
        I am now intrigued by one more as judicial practice in the net, nothing about this I can not find
        
        Nikolay (Sukhraj) I checked in last week. Now the expert will write a conclusion, and I will go to write a statement to the police, there is a refusal and with a refusal to the traffic police. I already did this once, on a different machine. We have an expert right in the traffic police, where they do the reconciliation of numbers. Gaishnik who checks the numbers and did not find the number on the frame. Says now I'll call an expert. The expert came up five minutes later. I looked. Gave the form of the contract. I filled. The cost says 2800, in five working days come for the results. If you want urgently, then plus 1400 r. So if you want to register, come to us in Arkhangelsk. Everything can be done in a day. The expert also told me that at the factory, where the car was made or the frame was lengthened, the number on the frame is painted with paint. I found these numbers with paint, but a few numbers remained from the full number. Another way. You take the numbers yourself, but if they find out that this was not done at the factory, then you will definitely not put the car on record. If you are interested, then on Saturday food to receive an expert opinion. After the police. How to register, then unsubscribe.
