There are a lot of trailers for cars and mini-tractors on sale, and if you wish, you can also find dump trucks, but the price of the latter is an order of magnitude higher. In theory, a small 2-wheel trailer can be easily unloaded manually by grabbing the drawbar and tipping it back.
For heavier loads, you can mount a box on a regular trailer, one side of which will be hinged, and the other will be lifting.
Trailers are divided into 2-wheeled (semi-trailers) and 4-wheeled, the former of which have high maneuverability, and the latter have a large carrying capacity.
Sketch of an optimal 4-wheel tipper trailer
If it is supposed to transport loads of 500 kg or more on a trailer, then it is necessary to make a strong frame. Steel channels or tauri are most suitable for it, and in their absence, you can use corners or pipes.
The sides and bottoms can be made both all-metal and in the form of steel frames sheathed with boards or plywood.
A very important element of a tipper trailer is the lifting mechanism. For these purposes, a long lever, a winch, a hoist, a chain drive through a gearbox, etc. are used. Drives are either manual or electric. The ideal option is a trailer bottom pusher based on a hydraulic cylinder, but it will scare away many with the high cost and complexity of installation.
As an alternative, you can install an arch with a manual hoist above the trailer, which will raise one side of the body.
Hello! Friends, I understand that it is not so rare that trailers are purchased for transportation, or the same ones. Although the majority of trailer owners still use them to transport goods. Someone needs to harvest in the country, bring building materials, solve some agricultural issues.
What am I for? all are good, I do not argue. But initially this type of equipment (trailer) was focused on cargo transportation, expanding the capabilities of the car and replacing the once cart with a horse. so discuss light trailer dump truck we just have to. Otherwise, we will not be understood.
Features and Benefits
When transporting bulk types of cargo on a trailer, there are no special problems with their loading. But unloading is accompanied by the need to climb into the body and start raking out everything from there manually, with shovels or other devices.
In such situations, the tipping mechanism becomes a real salvation. With it, unloading is much easier and faster.
The following advantages of such systems can be cited:
- simplify the process of loading and unloading;
- minimize the physical effort of a person;
- the speed of unloading bulk cargo can be controlled;
- suitable for working with all kinds of cargo;
- an indispensable device in agriculture and in the country;
- the mechanism can be installed by hand;
- does not damage the design of the trailer.
The essence of such a trailer is that its body has a movable connection with the frame. In conventional trailers, they are one-piece, which is why you can topple the entire trailer backwards, including the tongue and wheels. This is inconvenient and potentially dangerous. Therefore, it is strongly not recommended to unload bulk cargoes by this method from ordinary ones.
Device options
To get at your disposal a trailer that has a lifting (tilting) mechanism, you can go in 2 ways:
- Do it yourself. This includes building from scratch and reworking the finished flatbed trailer. Making a self-made dump trailer on your own is, in principle, not so difficult, since many people have enough experience and skills. I will give an example of how to make some variants of the mechanisms yourself. Although in the absence of experience it is better not to take on such work;
- Buy a ready-made version from the factory. Many enterprises, including MZSA (the same MZSA 817710) and (the city of Saransk) produce products where a tipping mechanism is provided. This is the optimal solution for many, since you get a 2 in 1. The trailer remains the standard flatbed, but additionally allows you to use the dump truck function. The design meets all the requirements and GOST, so there will be no problems with it. What can not be said about homemade devices.
If you are ready to use the blueprints and assemble a dump truck for a car yourself, I have nothing against it. Homemade trailer, manufactured in accordance with all canons and rules, may not be inferior to factory counterparts.
The only question is which mechanism you will use.
In total, trailers use the following options:
- hydraulic;
- pneumatic;
- mechanical (manual, without hydraulics).
What to choose? This good question, since each presented dumping mechanism has its own nuances.
The main thing here is that the body has a movable connection with the frame. If usually they are firmly connected to each other, then a hinged connection is used here. Its mating parts are welded to the frame and screwed to the spars. A latch is made in front according to the principle of a conventional latch. This prevents tipping over while the trailer is moving behind the car.
Before unloading, the latch is moved aside, releasing the connection between the body and the frame. It gets free movement, allowing you to unload bulk material, for example.
Factory trailers have their own characteristics of the device elements. But always the principle is to ensure that only the body (loading area) overturns, without affecting the drawbar and wheels. As a basis, it can use both single-axle and two-axle trailers.
But the lifting mechanisms are different. Let's consider them separately.
Hydraulic
If you have an ordinary light trailer, then I don’t particularly see the need for hydraulics. Although it's up to you.
Hydraulic systems are widely used in trucks and on tractors. The essence of such a device is that the drive is connected by a clutch and an oil pipeline to the drive from the car itself.
The advantage of hydraulics is that it allows you to tip the trailer body in different directions and at a fairly high speed without the use of physical effort.
The main problem is the complexity of such a mechanism.
Although there is a good alternative. To do this, use a pair of hydraulic cylinders mounted on the spars, as well as a hydraulic pump. It is not very easy to do it yourself, and buying a ready-made version is quite expensive. But if you have money and don't mind spending it, take it. You will not regret.
Pneumatic
Another version of the lifting mechanism is based on pneumatics. Good solution for homemade device. Although even here there are some peculiarities.
The pneumatic actuator is powered by exhaust system cars. Installed under the bottom of the car car cameras enclosed in a case made of durable material. Usually a tarpaulin is used. The cover is fixed on the bottom of the body and frame with the help of fasteners. You can take the screws, and make rings from a durable steel corner.
The chambers are connected with nozzles, nuts, gaskets and washers, a fitting is installed in the shape of the letter L. A hose made of durable rubber is pulled over it.
The essence of such a home-made mechanism is that you put the second end of this hose on exhaust pipe and step on the gas. The chambers are filled with car exhaust gas, due to which they inflate and the body rises.
If you need to lower the trailer body, remove the hose from the exhaust and that's it, the chambers begin to gradually deflate.
Mechanical
I agree that there are quite a few hassles and problems with pneumatics and hydraulics. In practice, most trailer owners make do with a conventional mechanical tipper.
Here it is also necessary that the frame and have a movable connection between themselves. This will make the body, as it were, partially independent and mobile. Ahead will be a manual mechanism with which the body tips back.
Although you can do without such a mechanism. It is enough to weld a support in the front. Then the body will tip over due to its own weight when you remove the locking device. But this is only relevant when using single axle trailer. Two-axle due to 4 wheels firmly and confidently maintain balance, regardless of the connection with the towbar of the car.
The advantage is that the price of such refinement is the lowest. And among the factory trailers, models with a mechanical tipper are the most affordable. And an excellent solution would be to use a winch. Comfortable, simple, and physically easier.
What to choose, it's up to you. You can watch different videos, take a look at the results of improvements to conventional flatbed trailers, or explore the range of well-established manufacturers.
In terms of safety, reliability and ease of use, I would advise you to purchase a factory dump trailer. Their range is impressive and price policy at a pleasant level. Yes, and with registration there will be no difficulties.
Since we are talking about tipper trailers as a vehicle for transporting bulk cargo (although you can carry anything you need), pay attention to a few recommendations for proper operation.
Observing them will help you avoid unnecessary fines and not endanger other road users on the road.
- Bulk cargo is transported only on special trailers designed for such purposes. Another reason to buy, and not to collect with your own hands;
- An awning, a plastic cover or other coating is laid on top of the body;
- The absence does not allow the transportation of bulk type cargo above the level of the edge of the side. Operation without an awning leads to the loss of cargo, its spillage onto the road and the creation of a danger to cars; put you in;
- Obey the speed limit when towing a trailer;
- Do not exceed the established norm for the carrying capacity of the trailer;
- To transport bulk cargo, the trailer must be equipped with rigid sides. Preferably galvanized.
At the factory, all this is provided from the very beginning. When altering a conventional trailer, problems and difficulties sometimes arise.
A trailer is a vehicle that does not have an engine installed. It is designed to be coupled with a vehicle. Despite the apparent complexity of such a device for transporting goods, it is not difficult to make a trailer with your own hands. For successful work, you need to choose the right parts and materials, complete sketches or drawings.
Transport trailers
The widespread use of semi-trailers and trailers is due to additional amenities in the transportation of heavy loads. Only part of the load falls on the car, which prolongs its service life. When unloading, you can save valuable time by unhooking the wagon and leaving it in place, and unloading at a convenient time. This option is convenient and is used for the delivery of goods between the shops of one enterprise, located at a certain distance.
All trailers are conventionally divided into two groups:
- trailers special purpose allow you to take into account the needs of working with various cargoes, and there are quite a few universal machines for such work. Common types include heavy semi-trailers, log trucks, panel trucks, cement trucks and other types of trailers.
- General transport equipment includes flatbed, tilt and other trailers of various sizes, designed to carry loads of any kind.
Varieties depending on load distribution
Trailer designs use a variety of steering wheel steering systems to improve the maneuverability and control speed of the road train. Hitch attachments are standard in most cases. If the trailer has an active wheel drive from the car engine, then such wagons are called active car trains.
To set such an active drive in motion is used mechanical transmission by means of a coupling device or a hydraulic drive is used.
If the road train has two or more links, then the engine is located in the rear section. Unofficially, there is the concept of "trailer", it is used to move cars, other equipment or oversized cargo (long or heavy).
Depending on the load distribution between the trailer and the tractor, trailers are divided into several types:
Requirements for transport devices
A person who independently wants to make a transport wagon for the movement of goods should study the requirements for car trailers. These standards are contained in GOST 37 .001.220-1980, which is called "Trailers for cars». A selection of these requirements include the following provisions:
Features of the use of wagons
Trailers are used only in accordance with the purpose, as this is due to the same tires and wheels with the main machine, track gauge, passage in certain dimensions ground clearance. The rule does not apply to heavy trucks and trailers-dissolutions. All breakdowns that appear during operation are similar to malfunctions. brake system and chassis of the main machine.
In addition, the operation of the trailer is disrupted due to damage to the hitch or wear of the rotary device.
To delay the repair of these systems, it is necessary to conduct regular inspection of the trailer. Since the operation of the device is associated with constant shaking and shock due to uneven movement on the roads, it is required from time to time to tighten the fasteners and align the curved parts. Before operation, it is necessary to check the serviceability of the springs, brakes, lighting, tire pressure, the presence of a spare wheel, the serviceability of the side and body locks.
Wagons are towed according to the rules, speeding is unacceptable, as well as sudden braking and unequal distribution of cargo. Increasing speed while driving will cause the trailer to wobble to the sides. Hard braking causes the car and trailer to fold, this is also facilitated by braking with the help of the engine. Due to the uneven storage of transported materials, stability is impaired and the trailer may tip over.
DIY manufacturing
In order to make a trailer yourself, you need to take care of purchasing some materials and tools. In order not to look for the necessary devices during work, they are purchased in advance. List of tools and materials:
Beginning of work
Assembly begins with the trailer frame, which is the load-bearing structure. It bears the main weight of the load. It is subject to increased requirements for reliability and durability. The prepared channel or square pipe is cut to size according to the drawing, two long and two short blanks are made.
They make a rectangular or square base in the form of a frame, to which the sides of a metal sheet will subsequently be attached. They pay attention to the quality of welding, since this is a sore spot for home-made caravans. The hitch is fastened in front of the manufactured frame. To install shock absorbers in the middle of the frame put special eyes.
It is the turn to make the side frame. For fastening the side railing, vertical posts are strengthened, their length depends on the height of the side. The vertical elements are interconnected by additional stiffening ribs, since during the movement it is the racks that experience the load from the displacement of the load. Additional reinforcing ties are made horizontal, vertical or placed obliquely.
Work with the undercarriage trailer is associated with a large number of difficulties and features. One of them is that the axle should be located closer to the rear of the trailer. Everything design features occur depending on chassis which car was taken for the trailer device. Shock absorber lugs and mounts are welded to the frame for jet thrust. The installation and use of the latter is mandatory, as they play the role of elements that support the bridge.
Final phase
Sheathing the sides with metal and making the bottom of the trailer from plywood is done at the final stage of assembly. A jigsaw is used to cut plywood according to the size of the internal space, and sheet steel is cut with a grinder. Bottom elements can be made from a single sheet or connected from pieces with a lead-in of at least 5 cm. All pieces must be attached along the perimeter to the frame and base elements using bolted connections.
The boards are cut to size, which are measured on the spot. At this stage, it is irrelevant to use the dimensions from the drawings, since during the manufacturing process the dimensions of the body skeleton, as a rule, differ slightly from those provided in the diagrams. Welding or rivets are used as fasteners, which also hold the material well. The boards are attached to all racks and reinforcing ties.
Electrical equipment
Elements of electrical equipment are installed on the rear wall of the trailer. These include red triangular reflectors, a flashlight reversing, license plate lighting, direction indicators, stop indicators, marker lights. On the wall in the front there are white dimensions and the same reflectors.
The side walls are designed for orange color reflectors. To keep the wires intact, they put on a protective corrugation. Wire connections must be secure and well secured. Corrugation with wiring inside is conveniently attached to the frame frame using plastic clamps.
Making a caravan requires skill and experience with power tools, but it will save you money compared to buying a ready-made vehicle from a store.

I bring to the attention of readers a trailer dump truck with a tipping body. Having made one for yourself, you can get rid of problems when unloading it.
A few words about the trailer device.
Its frame is welded from steel pipes of square section 40x40 mm, the bridge is from the SZD motorized carriage, using spring-hydraulic shock absorbers of the Ural motorcycle. The bridge is attached to the frame with the help of struts, also welded from square pipes.

The body is assembled from panels, each of which has a frame of 30x30 mm steel angles and 12 mm thick plywood sheathing on M6 screws with nuts. Two spars made of wooden beams with a section of 120x30 mm are attached to the bottom. Fastening the body to the frame - using a hinge, the mating parts of which are welded to the frame
and screwed to the spars; in the front there is a latch resembling a conventional latch, which prevents the body from tipping over while driving.

Now about the main thing - about the design of the lifting device. It is pneumatic, driven by the exhaust system of the engine. Under the bottom of the body, between the spars, there are three car cameras in a case made of durable fabric - tarpaulin or synthetic canvas, attached with M5 screws to the rings from a steel corner on the bottom of the body and on the frame. All chambers are interconnected using threaded pipes, nuts, gaskets and washers, and a fitting is screwed to the bottom, curved in the form of the letter “L”, onto which a rubber hose is pulled.

To raise the body, you need to put the second end of the hose on the exhaust pipe of the towing vehicle and “add gas”. Two or three minutes - and the body will rise. To lower the body, it is enough to remove the hose from the exhaust pipe. I. Khoroshevsky
Many farmers are interested in how to make a homemade mini tractor trailer. Most rural residents appreciated agricultural equipment, but only more economical and compact, such as a mini-tractor. On such a vehicle, you can not only plow, loosen the garden, mow grass and remove snow, but also transport various goods. And for this type of work it is necessary to have a convenient and reliable trailer. Many are hesitant to buy such a simple but expensive product on Russian market but trying to do it by hand. But where to start and how to make a do-it-yourself tractor trailer?
Photo: alexhobby.ruHow to make a trailer for a mini tractor with your own hands
First you need to decide what kind of agricultural work a trailer or a home-made trolley for a mini tractor will do. You can simply transport various goods, or you can transport manure and unload it using a dump truck. It will not be difficult to make the first option, but you will have to tinker with the second. Do not rush, you need to do it right away with high quality and thoughtfulness. First you need to draw diagrams. According to the drawings, a self-made cart or other types of trailers and tractor equipment will be manufactured. It is worth considering that hitch must have good carrying capacity and low weight. Then you should determine what kind of trailer to the tractor will be - two-axle or single-axle.
Consider how to make a single-axle trailer for a mini tractor with your own hands:
- First you need to weld the frame and the reinforcing crossbar.
- It is better to perform all connecting elements and pipe joints by welding. This will ensure the reliability and strength of the structure.
- Then you need to weld from pipes of a smaller section racks for the seat.
- Now let's decide on the choice of wheels. Since the product has 1 axle, 2 wheels are required.
- It's better to take. They fit perfectly in diameter and have a reliable composition. With a reinforced tread, the tractor will be able to perform more complex types of loads, drive on bad roads without exposing the tires to punctures.

But a home-made two-axle trailer for a tractor is a little more difficult to make than a single-axle one, because a cart with 2 axles needs to do more welding and installation work. The frame can be made, as for a single-axle trailer. With such a vehicle, if you are a fisherman, you can transport a boat.
A two-axle trailer has a more robust design, as it has 2 axles and 2 pairs of wheels, so it has a large carrying capacity.
Also, the weight of the transported cargo is distributed on it evenly.
Consider the requirements for the body. There are no strict correspondences at this point, but there is a choice. The body made of metal is more durable and reliable. But a wooden body will get wet in bad weather and collapse, even if treated with special anti-corrosion coatings. Other materials can be chosen, but aluminum and sheet steel work best. They are very durable, withstand heavy loads and corrosion bypasses them. Next, you need to weld the sidewalls for the trailer.
It is necessary to paint the entire frame and body, making it more secure and reliable. Paint should be chosen taking into account the material. If you chose wood, then the paint should be for wood products. The color certainly doesn't work. important role, but dark paint attracts heat, which is not necessary for a tractor. But the light color of the trailer for a mini-tractor will be just right, because it repels the sun's rays.
How to make a dump trailer
Let's consider how do-it-yourself home-made dump truck trailers for a mini tractor are made. If you decide to make a dump trailer, then you need to decide on the choice of lifting mechanism. There is nothing complicated here, as it seems at first glance. There are 2 options for dumping the trailer: manual self-tipping and mechanical. The first can be done by brewing to the front of the trailer handles. The tractor driver will lift the structure with his own hands. But one pen is not enough here.
See » How to make tuning of the LTZ T-40 tractor yourself
It is necessary to make an L-shaped pin, pulling out which the trailer will tip over by itself under the force of the load. Mechanical will be a little more difficult to do than manual. You can make a mechanism that raises the trailer from different types lifting equipment. For example, it can be a jack or an electric motor with a battery, a winch or a hydraulic system, or you can get by with an oil pump. Attach the mechanism to the body in the most convenient way for you.
To attach homemade trailed equipment for mini tractors to the very vehicle, you will need to weld an elongated beam and attach a towbar to its end that fits your tractor. The finishing touches are the painting of the structure you made, the upholstery of the seats, the inflation of the wheels. Then you need to check how homemade works.
Comparison of homemade and factory trailers
You can buy a factory semi-trailer or a dump trailer. Trailers for mini tractors are sold in all cities of Russia. But the price may disappoint you. The cheapest type costs 10 thousand rubles, not to mention the design with a lifting mechanism.
Why spend money if you can make a reliable and durable trailer for your equipment with your own hands. One has only to have the materials necessary for the case and, most importantly, desire. By the way, if you have not decided on the choice of the tractor itself, then a reliable assistant for working on agricultural land is the Belarus MTZ tractor. This brand of the manufacturer differs from others in its quality and durability. Let the price be above average, but in terms of characteristics it is not inferior to other devices.
