Tire fitting machines for trucks and cars

A car's quality repair in hard-to-reach places almost always requires the connection of mounting stands. These are quite massive structures, on which the entire machine or its individual parts can be placed. On a suitable for the construction of the working platform, the part will be more accessible to the master, which will make it easier and more efficient to perform repair work. To update the wheels are designed tire changers as a kind of the aforementioned stands. There are different designs and formats for the release of such equipment.

Characteristics of tire changers

The unit is a small platform on which dismantling activities are realized. As a power support, the stand can use both an electrical outlet and compressed air. As the typical instruction of the tire changer marks, in the second variant it is desirable that the compressor plant be not oil. This will relieve the air niches of the wheels from oil particles and small abrasives. In this case, the pressure level of the machine itself should slightly exceed the potential of the compressor.

Of course, the size of the wheels with which the stand can work also matters. But in 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 number of wheels to the segment of cars or trucks. Only in rare cases, deviations from this rule are possible when it comes to subcompact or special equipment. This is what concerns the diameter, but the width is different. So, tire changers for cars can work with a size of 12-15 inches, and trucks serve 45-inch analogues.

Automatic and semi-automatic structures

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 automatism. In fact, semi-automatic systems, in which mechanics support are provided, became an intermediate link. However, the user performs the control actions. The operator must manually press the shaft, lowering the presser foot. Thus, the turn of the installation site is performed.

The highest requirements to physical effort are most noticeable, if semi-automatic tire changers for large-sized vehicles are used. Automatic models do not relieve such problems, allowing easy maintenance not only cars with small trucks, but trucks with buses. Such units are often used in equipping car workshops, service centers, etc.

Features of stands for cars

Such models are designed for mobility, simple organization of power supply and, of course, a small wheel size - up to 24 inches. Automatic installations are equipped with an electric motor, which operates from a single-phase network. The convenience of this solution lies in the fact that the user can connect the stand not only to the power grid, but also to the generator. That is, you can perform repair work at a distance. Also, "light" tire changers as a power mechanism are supplied not with pneumatic systems, but with an electrohydraulic drive. This eliminates the need for additional organization of the compressor, but will have to prepare for a large cost of electricity. In sets with such stands, clamping jaws, a lubrication tank, a paddle, a gun for inflating tires and other devices are usually provided.

Features of stands for trucks

On the truck stands, the wheels are not placed horizontally on the table, but vertically. And they are held by a special lock with four clamps. Functions of power bodies in such machines are given special attention. Not only in terms of ergonomics of treatment, but also in terms of reliability. Depending on the type of wheel, the master has the ability to fine-tune the holders. Serving can be both chamber and tubeless tires, as well as models with a locking system.

Choosing a tire changer for trucks should be given the load. Since the wheels from the trucks differ in mass, the effort is also applied - about 1.2-1.5 tons. Moreover, the work process itself is not always safe, therefore, in modern models of such stands remote control is provided. Special control panels and controllers are installed on the site and connected to machine mechanisms with removal.

How to make a tire changer with your own hands?

At once it is necessary to emphasize, that it is expedient to be guided by models of a manual type, as they are easier and safer to operate. It will take three basic components: a frame, a vertical riser and a piece of a metal pipe. As a frame, you can take two profile rectangular tubes, which are located in parallel with each other. They should be connected with a steel corner. Further, a vertical stand is attached to the frame, which will perform two functions: a supporting base with a fastening and providing a place for fixing the wheel. Then the handle is inserted into the design, which will allow the tire changer to be activated. With your own hands, you can weld to a finished handle at this time a handle based on a piece of pipe.

Conclusion

Like any garage equipment, stands for tire fitting regularly need technical support. Therefore, it is possible to rely on long-term operation of the structure only in case of proper care. Also, you should prepare for minor technical problems. Home repair of tire changers, for example, can be associated with violations in the hydraulic mechanism or electromechanics. The power base rarely breaks, but in this part defects can occur at the joints of the functional parts. To prevent unpleasant nuances of using such equipment will help regular lubrication of rubbing mechanisms and the correct handling of technological control and control nodes.
