Tire changers for trucks and cars

High-quality car repairs in hard-to-reach places almost always require the connection of mounting stands. These are rather massive structures that can accommodate the entire machine or its individual parts. On a working platform suitable for the design, the part will be more accessible to the master, which will make repair work more convenient and efficient. To update the wheels, tire changers are designed as a variety of the above-mentioned stands. There are different designs and formats for the production of such equipment.

Tire changer specifications

The unit is a small platform on which dismantling activities are carried out. As a power support, the stand can use both an electrical outlet and compressed air. As the typical instruction of the tire changer notes, in the second option it is desirable that the compressor unit be non-oil. This will rid the air niches of the wheels from oil particles and small abrasives. At the same time, the pressure level of the machine itself should slightly exceed the capacity of the compressor.

Of course, the size of the wheels with which the stand can work also matters. But in thisIn this case, the difference is quite simple - the format can be either larger or smaller than 37 inches. That is, the division occurs according to the belonging of the wheels to the segment of cars or trucks. Only in rare cases, deviations from this rule are possible when it comes to small-capacity or special equipment. This is what concerns the diameter, but the sizes are different in width. For example, tire changers for cars can work with a size of 12-15 inches, and trucks serve 45-inch analogues.

Automatic and semi-automatic designs

The simplest mechanisms for tire fitting are manual installations, but large manufacturers have long abandoned them in favor of more convenient and productive models with varying degrees of automaticity. Actually, semi-automatic systems, which provide for the support of mechanics, have become an intermediate link. However, the control actions are still performed by the user himself. The operator must manually press the shaft while lowering the presser foot. In this way, the installation site is rotated.

Higher demands on physical strength are most noticeable when semi-automatic tire changers are used for large vehicles. Automatic models, on the other hand, eliminate such problems, making it easy to service not only cars with small trucks, but also trucks with buses. Such units are more often used in equipping car workshops, service centers, etc.

Features of stands for carsmachines

Such models are designed for mobility, simple organization of power supply and, of course, small wheel sizes - up to 24 inches. Automatic installations are equipped with an electric motor that runs on a single-phase network. The convenience of this solution lies in the fact that the user can connect the stand not only to the mains, but also to the generator. That is, it will be possible to carry out repair work at a distance. Also, "light" tire changers as a power mechanism are supplied not with pneumatic systems, but with an electro-hydraulic drive. This eliminates the need for additional organization of the compressor, but it will have to prepare for high electricity costs. Kits with such stands usually include pads for clamping jaws, a container for grease, a spatula, a tire inflation gun and other accessories.

Truck Stand Features

On stands for trucks, the wheels are placed on the table not horizontally, but vertically. Moreover, they are held by a special latch with four clamps. The functions of power bodies in such machines are given special attention. Not only in terms of ergonomic handling, but also in terms of reliability. Depending on the type of wheel, the master has the ability to fine-tune the holders. You can service both tube and tubeless tires, as well as models with a locking system.

Choosing a tire changer for trucks should be based on the applied load. Since the wheels of trucks are very differentmass, then the appropriate force is applied - about 1.2-1.5 tons. Moreover, the work process itself is not always safe, therefore, remote control is provided in modern models of such stands. Special consoles and controllers are installed on the job site and connected to the mechanisms of the machine with removal.

How to make a DIY tire changer?

It should be emphasized right away that it is advisable to focus on manual models, since they are easier and safer to operate. Three main components are required: a frame, a vertical riser and a piece of metal pipe. As a frame, you can take two profile rectangular pipes, which are parallel to each other. They should be connected with a steel corner. Next, a vertical stand is attached to the frame, which will perform two functions: a supporting base with a mount and providing a place to fix the wheel. Then a handle is introduced into the design, which will allow you to operate the tire changer. With your own hands, you can weld a handle based on a pipe segment to the structure that is ready at this moment.

Conclusion

Like any garage equipment, tire changers need regular technical support. Therefore, it is possible to count on long-term operation of the structure only in case of proper care. You should also prepare for minor technical problems. Home repair of tire changers, for example, may be associated with violations in the hydraulic mechanism orelectromechanics. The power base rarely breaks, but even in this part there may be defects at the joints of functional parts. Regular lubrication of rubbing mechanisms and correct handling of technological control and management units will help prevent unpleasant nuances of using such equipment.
