Unfortunately, no matter how good they are, they can break during use. What to do in this case? Should I take the car to a service center or try to solve the problem myself?
It turns out everything is simple. The fact is that there are not so many services for repairing this type of tool. Therefore, you will have to solve the problem of repairing the car yourself. To do this, accordingly, you need to know what problems you may encounter, as well as how exactly to solve these problems, relying only on yourself. Actually, this is exactly what we will talk about in this article.
The wheel burst. According to statistics construction wheelbarrow and garden wheelbarrow During their operation, they most often encounter wheel problems. Here, as a rule, there is one common problem- the chamber bursts or is punctured during operation. Of course, in this case, you can try to flange the wheel, and then seal the inner tube with a patch. Yes - the old-fashioned way, but it also has its place. However, thanks to the wide range of choices for this tool, today it is easier to buy a new spare part than to repair an old one. Accordingly, regarding the wheel, we note that it is best to buy a new wheel without a tube. The fact is that a tubeless wheel will once and for all save you from the problem of colliding with glass and piercing objects.
Another problem with the wheel occurs most often at the moment of overload. The fact is that any wheel on a wheelbarrow has a disk, which is made of metal or plastic. The disc itself is very light and consists of two parts. So, if the wheelbarrow is overloaded, the load on the disk will increase repeatedly, as a result of which the bolts can slip into their own technological hole. If this happens to your car, then you should immediately stop all work, bleed the air from the wheel, disassemble it and place washers of larger diameter under the bolts. Of course, this is a temporary solution that will allow you to gain time to buy a new wheel.
The frame burst. Very often, mainly due to overload, construction wheelbarrow and garden wheelbarrow faces such a problem as a burst metal frame. In that case, how do you home handyman, it is best to send to the online store in your city and buy welding inverter. Of course, this approach to business will not allow your equipment to continue to remain collapsible, as was the case with bolted connection. However, the use of a welded joint will make the structure of the wheelbarrow more rigid and, as a result, more durable.
wheelbarrow wheel construction tertiary about the supporting frame. We have already said that a construction wheelbarrow and a garden wheelbarrow should not be overloaded during operation. However, its users very often neglect this. Actually, it is precisely because of the overload that the wheel on the wheelbarrow begins to rub. The reason for this may be curvature of the axial part, as well as complete or partial destruction of the bearing system. So, in the first failure, it is very often necessary to change the load-bearing axial parts. In the second, the wheel as a whole changes.
The body has become highly mobile. As a rule, a construction wheelbarrow and a garden wheelbarrow under the influence of a load can lose their strength and become unbalanced. However, this problem is even simpler and can be solved by carrying out a simple diagnosis and inspection of your instrument. So, during the diagnostic process, it is very important for you to determine which of the bots on the car body is weakened. So, once you have found this, just tighten the necessary nuts and that’s it, your car will be back in service at the proper level of quality.
As you can see, construction wheelbarrow and garden wheelbarrow They don’t have many problems, but even those that exist can be easily solved by replacing something or repairing it with improvised means.
The wheel is the most vulnerable area on a garden wheelbarrow
Whatever one may say, the wheel is the most vulnerable spot on a car. At the same time, it is often destroyed not due to overload, but becomes subject to impact with piercing objects. This is true, therefore, to avoid this problem, we have to change the wheel to a new one, since repairing the old one is not always possible. So, when replacing a wheel with a new one, you need to choose a specific type of wheel from the following range of choices:
Pneumatic wheel. This type of wheel is considered the simplest and most common, since it is included in almost all wheelbarrows, both low and high price ranges. The basis of such a wheel is considered to be air, which enters a special chamber under the action of a pump. It is believed that the pressure in the chamber should be no less than 2 atmospheres. Note that such a wheel is relatively inexpensive, however, it can also cost half of the total cost of a construction and garden modification of a wheelbarrow.
Cast wheel. This type of wheel also has this name - tubeless. It usually costs significantly more and is supplied to the market only with a metal disk. The advantages of such a wheel include durability and ease of use. This is true, because the wheel does not need to be pumped, which means there is no need to waste time on servicing it. Note that many garden wheelbarrows in St. Petersburg are equipped with such a wheel, which are represented on the domestic market with a large assortment of choices. Note that garden wheelbarrows with tubeless wheels have long term service because there is no chamber with air inside. Therefore such garden wheelbarrows St. Petersburg cannot be pierced or cut with a sharp object. Note that the tire itself tubeless wheel is very durable, which significantly reduces the wear of the wheelbarrow during operation.
To summarize this article, we note that all wheelbarrows, construction and garden, are generally very strong and durable. All these nuances and problems are just isolated shortcomings that, with a very high probability, will not affect you. However, you must be prepared for anything in order to provide first aid to your construction or garden wheelbarrow if necessary.
Repaired car
The two-wheeled garden wheelbarrow shown in this photo served at the dacha for about 5 years, until its body became unusable due to its use in the construction of a garage, as vehicle for transporting crushed stone and sand. I must say that this is a comfortable and reliable car, at least it is much better than a one-wheeled one. 
The body of the car, made of galvanized sheet metal, was torn in its front part. 
At my dacha farm there was also a single-wheeled garden wheelbarrow, the chassis of which did not have any rigidity elements, and therefore its only wheel was constantly in a position of about 40 degrees to the vertical.
It was not possible to use such a car, despite its low (1650 rubles) price.
It was decided to replace the body of a two-wheeled car with the body of a one-wheeled one.
Manufacturers of garden wheelbarrows make them in such a way that individual parts and assemblies of one wheelbarrow do not fit into another, and first of all, the wheels do not fit.
To replace the body, I drilled new holes in the body in accordance with the holes for attaching the body to the chassis on a two-wheeled wheelbarrow, turning it 180 degrees in the horizontal plane.
The renovation was a success. It seems that for transporting light loads, up to 50 kilograms, a repaired two-wheeled garden wheelbarrow will last another 5 years,
To transport heavier loads (up to 120 kg) there is also a two-wheeled wheelbarrow, but its chassis is much stronger than that of the one I was repairing. 
The price of such a car in Vladimir is 3300 - 3500 rubles.
Over two years of operation, the wheel bearings almost fell apart, in addition, the tire cracked and tore and the inner tube was punctured.
Until new wheels arrived, I decided to slightly modernize and strengthen my garden cart.
I connected the handles together with an arc almost immediately after purchase, this makes it much more convenient to control the wheelbarrow, and besides, you can do it with one hand.
I have also long wanted to move the wheels closer to the middle of the body. I don’t understand at all those who designed such carts. Most likely, the design of the wheelbarrow that was used during the construction of the White Sea Canal was taken as a basis. The wheels of such wheelbarrows (one or two) are located in the front, so a significant part of the weight falls on the hands. Despite this, currently 99 percent of such products have wheels shifted forward. This applies to both garden and construction wheelbarrows, which, in my opinion, are not much different from each other.
In short, I decided to move the wheels closer to the center of gravity. At the same time, the distance between the wheels will increase slightly, but the width dimensions will remain the same. In addition, increasing the distance between the wheels will increase the overall stability of the car.
All parts were made from scrap metal lying around in different corners and adjusted using a grinder and emery.
First of all, I took two steel plates of suitable sizes, 3-4 mm thick, and drilled two holes in them, each dia. 10mm and installed between the body shell and the plastic trim in back wall cars. The length of the plates should be such that they protrude slightly above the bottom of the trough.
I threw out the thin tin in the front part, which apparently served to increase the rigidity of the body.
In its place I installed a steel strip of suitable dimensions. For this purpose, I came across a spring, straightened by someone at some point.
I adjusted two more plates to size and welded them.
Two vertical posts - pieces of pipe with a diameter of about 32mm. Their length is approximately half the diameter of the wheel, and is selected experimentally.
The axle should have a diameter of 20 mm, I couldn’t find one, so I set it to 18 mm, then I’ll come up with something.
It is necessary to check that the wheels rotate freely and that the tires do not touch the body. If necessary, you can put several washers or a piece of pipe on the axle. The bottom of the body should have a slope back, then when moving the arcs will not touch the slightest obstacles or uneven ground, as was the case in the factory version.
I forgot to take a photo here, but everything is clear. In place of the former axle, I attached a piece of pipe, adjusted and welded pieces of reinforcement dia. 16 mm. Below is shown by arrows.
I did all the steps without removing the body, so it’s quite easy to do the entire harness.
Every gardener and summer resident constantly needs to transport cargo around the territory of the plot or vegetable garden. The need to transport fertilizers to feed plants or Construction Materials may appear at any time, so purchasing is often required garden wheelbarrow. Devices for transporting goods over short distances differ in many parameters: size, number of rollers, tire material, etc. And you need to pay attention to all this when choosing a wheelbarrow in a store.
What types of wheels are there?
A wheel for a garden wheelbarrow can be pneumatic (with a tire into which air is inflated), cast rubber, or polyurethane. In this case, the disc material is not so important, since it is the tire that is subject to maximum load during operation.
Wheel for garden wheelbarrow
Pneumatic wheel
The rim for pneumatic wheels is based on a tire that has treads. Inside there is usually a chamber, which for reliability is made using two layers of rubber. Discs can be made of metal or polypropylene. If the manufacturer provides a bearing at the mounting location, the cart will move more smoothly.
Advantages:
- Increased load capacity. Depending on the size, a wheel of this type can withstand a weight of up to 300 kg. This is convenient for frequent use.
- Patency. At large sizes wheels, you can move the cart even on very uneven surfaces.
- Movement is almost silent. This important parameter. because when transporting cargo for a long time, noise can affect a person’s condition and lead to fatigue.
- Smooth movement. Due to the softness of the tire and the presence of a bearing, you can smoothly move the load on any surface.

On cast rubber
Cast rubber wheels for garden carts are made from high quality materials. The disc is made of cast steel. Additionally, galvanization is carried out for reliability and protection against metal corrosion. Thanks to this, high structural reliability, strength and durability are achieved, in addition, the design features of the connection allow you to quickly change the wheel.
The downside is that the load limit is quite low. Such a trolley cannot be loaded with a weight exceeding 200 kg. In addition, there is a slight shaking when driving, so these carts are not well suited for transporting fragile goods.
Note! Since the tread is molded, the wheelbarrow can be used when working on rough surfaces where pneumatic samples quickly deteriorate.
Made from polyurethane foam
This material is an alternative to cast and pneumatic options. A polyurethane tire cannot be punctured, just like a cast tire. At the same time, the smoothness and driving characteristics are the same as those of pneumatic wheelbarrows. Polyurethane is characterized by high shock-absorbing properties, wear resistance, and durability. No additional care is required to maintain performance.
Advantages of polyurethane wheels:
- Protected from rust, you can work in environments unfavorable for metal.
- Withstands both high and low temperatures.
- Resistant to mechanical damage and puncture. Because of this, it is possible to work even in areas with big amount stones or metal production waste.
- There is no need to regularly inflate your tires. The only one necessary care- regular cleaning of tires from dirt.
- The rigid tread allows you to move the cart on any surface, including slippery or loose soil.
- They exert little pressure on the soil, so the grass is not mechanically damaged when working on the lawn.
- The material is almost non-conductive electricity, which allows the use of wheelbarrows with such wheels in places where there is a danger of high-voltage electric shock.
- The thermal conductivity of the material is also low, which makes it possible to use wheelbarrows when elevated temperatures.

Wheel structure, features of its installation and dismantling
Main parts of the trolley and their functions:
- Garden wheelbarrow camera- storage compressed air. Its main functions are shock absorption and keeping the device on the move. If the tube goes flat, the constant bending of a hard tire with tread will lead to its damage.
- Garden Cart Bearing- needed to reduce friction of the wheel on the axle. In its absence, additional effort must be made to move the device for transportation, so a bearing for a garden or construction wheelbarrow is an essential part of any design. It also helps in absorbing bumps. There are 2 types of bearings - sliding and rolling. It is advisable to choose the first option.
- Wheel with tire- ensures the reliability and performance of the trolley. Most wheels are produced using the stamping method, using a template. The characteristics in this case depend entirely on the material of manufacture and the presence/absence of coating.
- Sleeve- is located between the axle holder and the wheel and prevents the latter from dangling.

How to choose the right wheel, tire or tube for garden equipment
The choice should be based on the location to be used. If you have to use it in an area with a lot of stones or debris, you should choose a tire with molded rubber or urethane foam. If the area has a lot of unevenness, it is better to choose a pneumatic one.
Important! The larger the wheel, the easier it is to move the cart.
What pressure can you inflate a tire with?
When purchasing a tire, be sure to indicate the pressure with which it can be inflated. Typically this value ranges from 25 to 70 P.S.I. However, it is advisable not to inflate more than half of the tire's maximum pressure.
How to change the camera on a garden wheelbarrow
Garden cart wheels often get damaged. To replace you will have to take the following steps:
- Remove the wheel from the axle.
- Using a flat spatula, remove the tire from the rim.
- Remove the bad tire; if desired, you can seal it or replace it.
- Pull the new flat tire around the wheel.
- Secure the tire so that the tire inlet valve passes through the tire hole.
- Inflate the tire and secure the wheel to the axle.
How to change the camera on a garden wheelbarrow
Why do tires and tubes fail quickly?
The main reason for failure is the presence of a small amount of natural rubber in the composition. Phenols are often used instead. With prolonged use or elevated temperatures, it appears bad smell. At lower temperatures, the elasticity of the wheels is lost.
The choice of garden wheelbarrow must be approached carefully, and Special attention pay attention to the wheel, since it is this that most often fails after 1-2 years.
