As more and more of our camrades enter the ranks of mobile water trucks, acquiring light inflatable boats and trailers for transportation, I decided to talk a little about my experience and modernization of this equipment.
First, the answer to the question is for what you need to lengthen the trailer?
The thing is that for transporting light boats with inflatable sides, whether it is a PVC or a small rib, equipped, and not very heavy motors - do not need a large and powerful trailer. After all, the mass of this kit "Boat + Motor" easily places in 200-220 kg. Those. For carrying capacity, it is quite suitable for a lighter and cheap trailer designed to transport hydrocycles. However, with such a small weight, the length of the boat was transported can reach 4.5 or more meters - it may simply not fit on the trailer. Of course, you can, of course, move forward a nasal focus, not forgetting that according to traffic rules, the cargo cannot appear for rear dimensions Trailer more than 1 meter. However, this position of the boat is extremely inconvenient if backdoor The car-tractor opens not upwards, and Block (my situation) - while the trailer with a boat is attached to the car, access to the trunk is extremely difficult. Here then it will help a slight lengthening of the drawing of the trailer - 40-50 cm in our case plays a big role. Also, these extra half-meters can be healthy to help the water boat in an unequipped place when the wheels are not asphalt or concrete under the wheels of the car.
So, let's begin…
Determine the profile drawn. In my case, this is a pipe of a rectangular cross section of 80x40 mm with a wall thickness of 5 mm. In any stall, the trading metal, with joyful such a piece will be cut off. The cost of its order of 150 p.
Before starting work on the elongation - do not forget to cut off and pull the wires and plug out of the breath. Wires we will then increase. Cut better here.
Now we take the barrage and with an important look saw your trailer. In this case, it was possible to go in two ways - do not cut anything and get along with one suture, just welding a piece to the beginning breath. But then I would have to replete two holes for fastening the hitch and two holes for fastening the rolling wheel. Yes, and brew old. I decided that it was easier to cut and brew a piece in the middle.
Important moment. The curve trailer us, understandable, is not needed, so - before welding, carefully position the details.
We grab, make sure that everything is smooth, we welcome, we clean. It should turn out something like this.
With the second seam I had to tinker a little, because it was not very comfortable. But in the end everything is ready.
Ground up in front of painting. I used car paint. With zinc in the color of the trailer and the usual car ground. Callers are 150 and 100 p, respectively. While the applied soil dries - we will deal with wires. Cut slices, more cooking lengths for 10. This is necessary for the subsequent convenience of the connection. Sockets of the wires of the wires I shipped - if the contact will disappear due to oxidation (and the water in the drawbar is almost always) - you will have to disassemble everything.
Since I didn't have multi-colored wires, so as not to confuse when assembling, the ends of the scores were marked with pieces with numbers and recorded which digit what color matches. We collect harness.
When the soil is dry - we paint the main paint. It remains to drag the harness in the drawby, repeat the operation on the splicing of the wires - and Voila! Everything is ready. That's how it should turn out. Slightly stepping - and nothing will be seen.
They are afraid of a decline in maneuverability with such an upgrade no need. The radius of the turn does not change, but it will become much easier to maneuver the trailer when driving back.
How to upgrade the lifesters of the trailer under the long boat - in the next part.
MMZ trailer serially produced since 1972. Fixture is intended for transportation of different types cargo and tourist equipment. Basic tractor for this unit is the VAZ-2101 car. Both funds have the same nodes: tires, shock absorbers, bearings. The MMZ trailer can be operated in aggregation with other passenger cars of domestic and foreign production, which are equipped with a regular traction hitch.
Device
The following parts in question include following:
- Rama and drawn.
- Awning with arcs.
- Body.
- Running part.
- Castle.
- Racks supporting.
- Electrical equipment.
- Alarm.
The MMZ trailer frame is made of steel by welding. It consists of a pair of longitudinal beams and three transverse elements. The spars have a trapezoidal cross section (50/32/25 mm), made of steel. In the frontal part of the converging spars, a lock fixture is welded. In the middle there are brackets on which the springs of suspension and shock absorbers are attached hydraulic type. The rear crossing is equipped with fastenings of buffer and support racks. In addition, the holes are done under the bolted body mount.
Characteristics of trailers MMZ
The body part is made of steel by welding. The bottom and board are made by the method of stamping from sheet steel (0.7 mm). Inside the body in the side of the side sides includes wheel niches. The floor is covered with rubber corrugated cape. The upper strappings of sides are equipped with nests for mounting awning arcs, which are pipes of certain diameters. The awning itself is made of tarpaulin, fixed on arcs using a special cord that has been done through the brutants, located along the edges of the canvas.
The lacing is carried out between the champs, it is pounced on the strapping hooks that are welded to sides. Chassis The MMZ trailer is from the following elements:
- Wheels with VAZ-2101 tires.
- Tubular axis with welded along the edges of the Tsazpami.
- Transverse and longitudinal rod.
- Spring suspension mechanism.
- Hydraulic telescopic type shock absorbers.
- Fixing shock absorbers brackets.
- Rubber buffers.
- Bumps.
Equipment
Passenger trailer MMZ completes three support racks. They are mounted on the platform for blocking the springs of the suspension. Electrical equipment devices - single-wire type, powered by automotive on-line voltage 12 V. This also includes a couple. rear Lights, License plate backlight, Wiring set with a fork.
Rear light elements - two-chamber type (in the upper compartment there is a single rotation pointer lamp, and at the bottom - analogue with two threads, denotes a stop signal and dimensions).
Features
The front MMZ is equipped with a pair of reflective circular configuration and white kolat. Rear is provided by a couple of red triangular form reflectors. In 1986, the board began to make collapsible, new reflectors appeared. Advanced variations got shifted axis, smaller wings, mudguards. Later began to produce models without bumpers, instead of which were simply two protrusions, options with updated optics and various combination of dogs. The frame number is located on the right under the folding part of the side.
Alteration of the trailer MMZ
Below is one of the ways to upgrade the adaptation under consideration. The essence of tuning is to dismantle the body and replacing all elements to the maximum. Initially, we mount a new castle, then sandblasting and painting of sides are carried out. The main process includes the following steps:
- Replace the rear shock absorber with sleeves.
- If these elements are suitable for further use, do not have signs of deformation - it is better to leave them, especially if they are made during the Union.
- As spring mechanisms, you can put analogs from "Oka" or "Zaporozhets" (if constant and maximum load is envisaged). In the second case, you will need to purchase springs.
- As rear shock absorbers Details from VAZ-2101, "Moskvich" or "Niva" are suitable.
- Use bolts 12 * 60 mm for fastening.
- Changes from wood under the body can be changed on a metal profile.
In the case of friction of tires about the springs, use additionally spacer from brake disc VAZ-2101.
Modernization
Trailers for passenger cars, the price of which starts from 200 dollars (depending on the state of the "TV"), one can improve in another way. Stages of work:
- Replacing the coupling device to a new version.
- Mounted hubs and handbrake.
- From an ordinary jack, you can make an additional support on Dyshle.
- Next is the replacement of headlights (you can buy new elements or use the lights available in stock, for example with VAZ-2108).
- The design is trimmed with galvania.
- Further remake of the MMZ trailer is the restoration of the suspension. To do this, we produce the replacement of the hubs on the plates with the VAZ-2108 (with the beam beam).
- Rama is enhanced.
- Conducted painting design.
Technical specifications
Performance of the trailed device under consideration:
- Full weight - 300/450 kg.
- Mass of the transported cargo - 135/285 kg.
- The limit speed in the hitch with a car is 80 km / h.
- Length / width / height - 2.6 / 1.6 / 1.02 m.
- Clearance - 25.8 cm.
- Wheel rinse - 1.34 m.
- Platform Square - 2.12 sq.m.
- The dimensions of the inside - 1, / 1.5 / 0.38 m.
- Connection - ball type.
Restoration
The repair of the MMZ trailer can be performed as follows (the initial model was practically relocated on the seams):
- Resuscitation begins with careful with the close-up of all cracks by welding. Next, the diagonals are checked, the boards are tightened with a soft roller wire with a further amplification of the corners. There is still a pair of amplifiers on the bottom part. This operation is related to the fact that the long-time performance is equipped with only one amplifier, which is not enough for full-fledged exploitation. As a result, the metal is torn, the bottom simply fails.
- It is possible to cook from the primary means a new body bottom as an additional layer on top of the main element. For this purpose, several pieces of iron thick 3 mm are quite suitable. To start, the segments are welded among themselves, and then with the main coating. For reliability, the entire design is fixed with bolts with pressshabs.
- Mount the reinforced springs.
After restoration, the MMZ-81024 trailer was reinforced (transportation of cement, sand, rubble). For 4 months of operation - no complaints, even compared to the new sample.
This article is a continuation of an article on the bulkhead of the trailer. While I slowly collected a trailer, various ideas appeared on its retrofit. Since now it can be fully exploited, it began to think about why not wait somewhere on a dalnyak. In this article I will consider the improvement of the trailer from the point of view of long journeys.
Repeatedly arose the question of where to place a zip for a motorcycle. Under the seat of Zidovskoye technique (where the tool and the pump lies) I will not put anything particularly. But the little thing is still possible, if you wish, you can place, only again it is not convenient to get it. Yes, and on the road you can lose if you do not try with packaging. In general, not as critical, but there are no inconvenience. The first element I decided to add a box for a zip. The second element has become spare wheel. It was asked back there. Point in the teller put the trailer VMZ 9.601. Only there is a spare wheel located lying. All attachments decided to accommodate with the help of brackets on the front side. Removed the sizes from the box and wheels. Made a drawing. The clashes on the box folding and here it is necessary to take into account the distance between the box and the wheel, otherwise without dismantling the spare track, the box will not open.
I try on a box with a wheel to board. The next concern was to reduce the distance between the vehicle and the trailer. Only like that, I left, replacing the body ... I no longer want to give up the idea. Just in case, it began to work out the extension options drawing.
For greater reliability of brackets, a rolling steel strip 30x4 mm was chosen, the stap, hot-rolled brand. Additional trailer body measurements, drawing a blank with a markup and a ready-made bracket. From each edge made technological indents. For accurate bend, a width of up to five millimeters is provided.
From the solid band, we cut four blanks for future brackets. The length of each workpiece three hundred seventy millimeters.
In accordance with the drawing, make the markup of the billets. Next, the part is performed.
After all the workpieces are flowing in place of bend, begin to give the desired part form.
Site of collapse. Bend the material of such a thickness without a machine or special devices at an angle of ninety degrees in the garage is not real. You can try to warm up, but make four absolutely the same details are hardly done. And aesthetic appearance can also suffer. It is easier to cut the workpiece for me, and then fool it.
From each edge of the workpiece made a technological indent of several millimeters. Next you need to trim the item at the place.
At the site of the adjustment of the body-bracket, the welded seam is a little stable. This is the only weld seam that needs to be modified, the rest can not be touched, as they are not in contact with other elements.
After the opener is a technological gap and fit the part with one of the sides, we do the formation operations further.
As the angle was selected, we fell the rest of the details and cook the place of bend.
Spilting technological gap.
Partial brackets are ready. Drills holes and screw the box.
We try the wheel. Through wooden spacers, screw the brackets to the spare wheel. In accordance with the drawing, we adjust the hinged elements relative to each other. Check the ability to open the door of the box. We place fasteners on the body.
Wooden races Spacers replace on aluminum bushings. The brackets are made, then paint the items.
Spacers are installed between the wheel rim and the bracket. With four bolts, we screw the spare wheel to the bracket. To assemble the wheels, we use two original wheel mounting bolts to the hub. Wheel mounting bolts in this case are long. Use spacers. We collect the wheel and screw the brackets. After the fitting it turned out that one of the bolts rests on the hook for rope awning. Stead the bolt and a little welded nut taking into account the rendering of the awning.
We screw the brackets to the box.
Install the hinged elements and screw them.
We collect the box, install the loop, the door lock. Insert the seal and put the door to the place. In the course of the works were painted and installed arc awning.
It came to the awning.
Installing a box for a zip and a spare wheel completed.
Hello, friends! Since not always a factory trailer can fully satisfy the needs of its owner, many are solved on constructive changes. vehicle. All sorts of trailer remakes aimed at achieving them the characteristics that will arrange you.
But what can be created from it and how strongly the trailers are able to modify? Take about it and talk.
The legality of modernization
I will not speak specifically how to make one or another tuning. Is it possible to change the design? This is the first question, the answer to which you need to find.
I will say so. Some changes may not require any adjustments to your documents. But the cardinal tuning will potentially become the object of disputes with employees of road services.
Therefore, before turning your usual trailer for a passenger car To the camper or use it under the house on the wheels, consult on the traffic police.
Tuning requires obtaining appropriate evidence of changes in TC design. We will have to go through a number of the offices, paying state duties, stand in queues, etc.
Although many just ignore it. They upgrade the route as they wish, and already on the spot with traffic police officers find out how legally it is and how such prohibitions get around. If you want to get rid of extra stops on the roads and incomprehensible fines, go through a long, but legitimate procedure for reissuing the trailer. it optimal option, in my opinion.
Well, instead of alteration under PVC boat, immediately buy yourself a trailer intended and certified for such purposes. Alteration is troublesome, although it is always nice to observe the results of the work carried out by their own hands.
Why it is necessary
And indeed, why take and change the finished trailer, if initially its scheme or design you completely satisfied?! The question is purely personal and depends on the individual needs of the car owner.
Take a few good trailers for example:
- MMZ 81021;
- Scythian;
- VMZ;
- KMZ 8119;
- MZSA;
- Kurgan trailer, etc.
Good TC with enviable for many manufacturers with technical specifications. But if suddenly there is a need to use them for the carriage of boats or for the transport of a motorcycle, they will not be able to cope with such tasks.
Yes, for trips to their cottages and loading several bags of potatoes assembled on the garden, any standard autographs are perfect. But I want something else and more.
I would allocate several main goals that pursue car owners when solving change the trailer:
- increase functionality;
- increase loading performance;
- change B best side reliability parameters;
- modernize purely appearance TC.
Now we will walk separately for each of the items and decide what can be done in a particular situation with its factory standard trailed vehicle.
Reliability
If you are worried about the issue of reliability, then it is better to immediately take yourself more expensive and stable to all loads and impacts trailer. Then you will not have to think about whether he can serve for 5-10 years.
To reduce the speed of wear, that is, to increase the reliability of its passenger, cargo or boat trading, you can:
- make the body and the bottom of the trailer with the help of ordinary plywood;
- change standard optics on LED, which serves as long and less loads the power supply of cars;
- apply an anti-corrosion tool on the body;
- handle the body of high-quality paint;
- put awning (we spoke about it separately here in this article).
A variant with the replacement of the hubs, the modernization of suspension and other improvements is possible. Very popular is the transition of the trailer bee for springs with standard torsion. Good affects reliability, performance features And the behavior of the trailer on the road of different quality. So it is worth thinking.
Functionality
Many are more interested in the functional side of the trailer, that is, its ability to provide different additional possibilities.
Different options are available:
Everything is limited to only your fantasy, needs and real features. It is clear that from a small cheap trailer make a whole huge home on wheels will not work.
Yes, the modernization of the boat in the cargo trailer is a more complex process, because you will have to create a framework, board, set the awning with your own hands. It is easier to make a cargo boot, because all the extra designs are removed and the corresponding limiters and fasteners are mounted. And all, the TC for the carriage of the boat is ready.
There are many examples of photos and videos, where the craftsmen changed the design of the autographs, or turned them into a real work of art. There is always something to rely on where to take examples and inspiration.
Load capacity
If you need to carry loads weighing up to 1.3 tons, then it is enough to have a conventional uniaxial trailer.
But sometimes it is required to increase the load capacity, for which another 1 axis is added. From the union, we get a two-axis. The solution is good if it justifies itself from the position of active exploitation.
Get ready to stand in the queues and do a paper fiber. A similar alteration into a two-axis TC requires the re-registration of the travelers in the traffic police. Otherwise, fines are not able to power, or even more serious consequences of illegal alteration.
Appearance
Not always in the trailer the owner must be changed its technical and functional characteristics. But the standard appearance depresses that it comes to the idea to change something from aesthetic point of view.
We turn on the fantasy and proceed to work. From the most common can be allocated:
- installing new optics;
- installation of original reflectors;
- painting body;
- upgrading beautiful protection;
- replacement;
- installation on perimeter lED tapes for highlighting;
- replace disks and rubber.
If the driver often faces the problem of freight, then rental transport becomes disadvantageous and expensive. It is much easier to acquire your own trailer. The question of buying a new or used cargo trailer is solved depending on the planned budget. However, sometimes even new acquisition requires additional improvements. 
Why redo?
So, the purchased new thing is framed and waiting for operation. But not always factory variants of trailers meet the requirements of the consumer. The tuning of the trailer for a car can be performed with different goals:
- increase functionality;
- increased lifting capacity;
- strengthening reliability;
- improving appearance.
Cash infusion in the trailer are inevitable, sooner or later will have to take care of his condition. Options and methods of these improvements will consider below. 
We increase the reliability of the acquisition
If it is used often, that is, the reason to strengthen it initially. Then the question of the longevity of operation will not disturb the owner. So, what can be taken to slower wear:
- shelter body and bottom plywood (Faneru can be planted independently for ordinary dowels);
- replace ordinary LED lights (they are more resistant to external stimuli);
- treat the body to the tool against corrosion;
- paint quality paint;
- move the license plate so that it does not be launched;
- install the awning.
If these manipulations require large cash costs, rather than the driver can afford it can be carried out gradually.
Make more functional
Here every driver agrees that a lot may come in handy on the road. In addition, everyone needs different. The trailer can be equipped with the following useful things:
- basket made of steel profiles for zip;
- a tank of a fishing room;
- fuel tank;
- electro pump;
- additional fasteners: rings or brackets;
- traffic restricter for transportation of vehicles (for example, motorcycle).
Load capacity - how to increase?
If transported the cargo does not exceed 1300 kg, then the usual trailer to a passenger car with one axle will be enough. But sometimes there is a need to strengthen the possibilities of the vehicle. Loading can be strengthened by adding another axis. In this case, there is a reson to strengthen the trailer frame. However, this manipulation adds legal troubles: such changes require re-registration in the traffic police. 
Aesthetic moments
For each driver, the car and all that is connected with it, the subject of love and adorations. Therefore, very often tuning is not a necessity, but the way to "pamper" your vehicle. Therefore, the trailer can be originally painted, decorate with additional reflective details, equip beautiful protection.
So, there are a variety of refinement options. freight trailer. A good master may not just change the appearance of the vehicle, but also increase its functionality and extend its workable age.
