When buying a car, many car owners, over time, come to the conclusion that they just need a trailer. And this is not surprising, since the luggage compartment of the vehicle has a limited volume, and sometimes there is a need to transport bulky goods.
Automobile for a passenger car may differ in their own way appearance, but they all have similar design features:
Of course, there are several more important components that may be included in the design of such products. For example, a support wheel for a trailer.
The purpose of the support wheel for car trailer- provide the ability to move the entire structure without using the car itself for this purpose. The rolling wheel has replaced the supporting leg with a collar. The second option is intended primarily for fixing the product in one place, but also allows you to move it, due to the application of a certain physical effort.
A rolling wheel for a trailer greatly facilitates this process, since it does not require the use of physical force to lift and hold the product in weight.
In fact, the choice of such a device is not easy enough, since there is a fairly significant variety available options. Removable type - is installed on the supporting leg only when it is necessary to fix the trailer in one place and then it can be easily moved from place to place.
Foldable option - what is it? When the trailer is lowered onto the support, such a design is automatically set to working position. During the connection of the car trailer to the vehicle, the support wheel for the trailer is hidden under the drawbar of the entire structure, thereby completely without obstructing traffic even under extreme conditions. There are also options that allow you to easily change the height of the supporting leg, which ends with such a wheel.
Naturally, the trailer support wheel clamp is the most important component of the entire structure. It is this part of the product that allows a person to easily manage a rather large and not the most lightweight construction, which is a trailer for a car.
Any motorist also has a choice of how to become the owner of such a system:
For an example of making such a design on our own, we decided to consider the option of creating a rolling wheel from a jack with our own hands.
What does that require:
From the tool you will need:
The advantage of this option lies in its simplicity and speed.
The process looks like this:
The system, assembled from a minimum of parts, is completely ready for testing and active exploitation. The main advantage of this option is that now lifting the drawbar of a heavy trailer will not be a problem even for a person who is not physically developed.
I ADDITIONED MY CAR TRAILER WITH A LIFTING DEVICE. I NOW UNLOAD AND LOAD HEAVY ITEMS MUCH EASIER AND FASTER.
From profile pipe with a section of 50 × 50 mm welded a subframe (photo 1 p. 1) right size, bolted the drawbar and the wheel axle to it.
I welded hinges to the rear crossbar of the base (photo 2), with the help of which I fixed the frame with the body on it (the mount allows the trailer to be used as a dump truck).
I welded fixing locks to the side rails of the subframe at the same level (photo 3), which prevent the trailer from lifting while driving.
For the stability of the structure during loading or unloading, I welded retractable stands (photo 1, item 2) from a profile pipe and plates to the corners of the subframe at the back.
Important!
The height of the stands must be selected based on the distance from the subframe to the ground.
From a profile pipe with a cross section of 50 × 50 mm, I welded a small rectangular frame (photo 4, p. 1) for installing a crane and attached it to the front crossbar of the subframe. Inside one of the pipes of the resulting stand, I fixed the retractable leg (2).
From sheet metal 5 mm thick, I cut out a platform (3) of the required size and welded a piece of pipe d 89 mm (4) 300 mm long (longer) to it - this is the base of the crane. For reliability, the pipe with the platform was additionally connected with stiffeners.
I made a stand (5) from a pipe d 79 mm. At one end I fixed two plates (6) in parallel, and welded the lower end and inserted it into the base, after pouring lubricated balls from the bearings into the latter (this allows the stand to rotate freely).
Between the rack plates, I bolted an arrow (7) made of pipe segments with a section of 60 × 60 and 50 × 50 mm.
To adjust the boom for tilt (3 working positions and 1 traveling) and reach (3 positions) in pipes and plates, I drilled holes (8) of the required diameter into which stoppers (9) are inserted. I welded a plate to the boom and fixed a hand winch on it. The finished crane installation was screwed to the frame.
Hello, friends! Each of us strives to make the operation of your car and auxiliary equipment as convenient and practical as possible. One of these components is the supporting wheel for the trailer. It's also bouncy. But call it whatever you like.
This is not just a support, but a tool that allows you to greatly simplify the handling of the trailer, making it easy and quick to move without using the machine itself.
The rolling wheel performs an extremely simple but very useful task. It makes it possible to move the trailer without connecting it to the car and without trying to park or move it somewhere with complex maneuvers.
Initially, a supporting leg with a collar was used for a light trailer. This design made it possible mainly to fix the trailer vehicle at one place. But if the driver could make certain physical efforts, then it was possible to displace the vehicle.
Rollers are mounted on the drawbar of the trailer, fixed with a clamp or by welding. A swivel collar is preferable because it allows you to give the wheel an optimal position when moving the vehicle.
With the help of rolling wheels, these procedures have been made easier and physically easier. Now you do not need to strain all your heroic strength to lift and hold the trailer on weight.
Good support with rolling wheel ensures high level operational comfort for the driver. Support wheels can be made by hand. To do this, you will need special wheels without a stem, some kind of metal tubes and a number of auxiliary parts.
If you don’t want to bother with the assembly or homemade device does not inspire confidence, you can just buy in Moscow, Novosibirsk, Samara, St. Petersburg or Yekaterinburg, for example. Yes, in any city you can find this simple device. I don't recommend buying used. The price of the device is small, and buying a used device is always a risk.
You have decided for yourself that your trailer definitely needs a rolling wheel. This is logical because it has important advantages.
Let's stop there. The points presented are enough to understand how much useful the installation of a support wheel provides.
You can install the design on any. Therefore, if you or Krepysh, for example, they can easily be supplemented with such a system. And for a boat trailer, a rolling wheel will only benefit.
But you still need to choose the right device. You need to rely on several basic parameters:
I propose to go through the points separately. This will allow you to understand what kind of road wheels are, what is the difference between them and who should be preferred specifically in your case.
Start with this. Removable devices are installed on the supporting leg when it is necessary to fix the vehicle in one place and move it as necessary.
There are also foldable structures. Here, when lowering the trailer, the rack with the wheel in the automatic mode is set to its working position. When the vehicle is connected to the towbar of the car, the entire structure is folded under the drawbar and does not interfere with further operation at all.
On some rolling devices, the function of adjusting the height of the supporting leg is available.
Support wheels are automatic and mechanical.
The machine has obvious advantages, although with a rare use of the trailer, this will not particularly affect the level of driver comfort.
Based only on photos and videos, it is impossible to say exactly what load the device is designed for. And in terms of carrying capacity, they can seriously differ. This figure varies from 150 to 500 kilograms for light trailers.
If you have a small trailer up to 750 kg, then it is enough for him to take a support with a vertical load parameter of up to 150 kg. When the gross vehicle weight is 1-2.5 tons, the support wheel is selected by 300 kg. Already in the case of cargo trailers, a load capacity of 800 to 1500 kg is required.
Additionally, I advise you to pay attention to the support bearing in the handle of the support wheel. If it is, it will simplify and extend the life of the device.
Rubber can be solid or pneumatic. Pneumatic tires are characterized by smoother running characteristics. But behind this advantage lies the need for careful maintenance of the structure. Therefore, think for yourself what is your priority.
As for the discs, they are plastic and steel. There is no particular difference in operating conditions between them. They both withstand the load for which they were designed. Although for some, the material of the disc may play a role in the choice.
If we talk about manufacturers, then I can’t give specific recommendations here. Each one has its own characteristics and requirements. Plus, everyone has different financial capabilities.
I can only say that buying cheap devices does not make any sense. They wear out quickly and are more trouble than they're worth. Wheels from Winterhoff, Al-Ko, SPP and Knott are considered running. These are all European companies that have proven themselves well in the Russian market.
I added my car trailer lifting device. I now unload and load heavy items much easier and faster.
For the stability of the structure during loading or unloading, I welded retractable stands (photo 1, item 2) from a profile pipe and plates to the corners of the subframe at the back.
Important!
The height of the stands must be selected based on the distance from the subframe to the ground.
I cut out a platform (3) of the required size from sheet metal 5 mm thick and welded a piece of pipe d 89 mm (4) 300 mm long (longer) to it - this is the base of the crane. For reliability, the pipe with the platform was additionally connected with stiffeners.
I made a stand (5) from a pipe d 79 mm. At one end I fixed two plates (6) in parallel, and welded the lower end and inserted it into the base, after pouring lubricated balls from the bearings into the latter (this allows the stand to rotate freely).
Between the plates of the rack, I bolted an arrow (7), made of pipe sections with a section of 60x60 and 50x50 mm. To adjust the boom inclination (3 working positions and 1 traveling) and reach (3 positions) in pipes and plates, I drilled holes (8) of the required diameter into which stoppers (9) are inserted. I welded a plate to the boom and fixed a hand winch on it. The finished crane installation was screwed to the frame.
Support wheel for a trailer, or rolling - a device to increase the maneuverability and stability of this unit. In fact, the principle of operation is based on a jacking mechanism, the lower part of which is equipped with a wheel. It is fixed on the drawbar, crimped with a clamp or welded. Swivel collars create additional convenience when moving. The support wheel contributes to the competent weight distribution of the transported cargo and ease of operation of the trailer without the assistance of a car.
The rolling wheel for the trailer has an extensive list of positive qualities:
The purchase of a support wheel for a trailer involves tracking some of its technical characteristics:
Removable or foldable:
Automatic or mechanic?

The design of the support wheel is a telescopic system, that is, two tubes: a rod and a body. Automatic system implies the presence of a bracket, when pressed, the wheel automatically drops down. A mechanical is a conventional jacking device.
Support wheel load capacity. Varies from 0.15 to 0.5 tons for cars:
Support wheel made of solid rubber trailer KMZ 8284 51
For trucks, the value is higher than 0.8-1.5 tons.
Rubber and discs for the support wheel are an important component. The supporting wheel for the trailer is equipped with a pneumatic tire or solid rubber. Pneumatic tires have better grip on the road and do not skid in the sand, but require timely pumping.
Regarding discs, they are made of plastic or steel. Although plastic can withstand significant loads, steel wheels have a greater margin of safety.
