High-quality car repair in hard to reachplaces almost always require the installation of mounting stands. These are rather massive structures on which the whole machine or its individual parts can be placed. On a working platform that is suitable for the construction, the part will be more accessible for the master, which will make it easier and more efficient to carry out repair work. Tire fitting machines are intended for updating the wheels as a kind of the above-mentioned stands. There are different designs and formats of production of such equipment.
The unit is a small platformon which dismantling activities are implemented. As a power support, the stand can use both an electrical outlet and compressed air. As the typical instruction tire changer notes, with the second option, it is desirable that the compressor unit is not oil. This will relieve the air niche 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, withwhich can work booth. 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 belonging of the wheels to the segment of cars or trucks. Only in rare cases are there possible departures from this rule when it comes to small-capacity or special equipment. This is what concerns the diameter, but the widths of the standard sizes are different. So, tire changers for cars can work with a size of 12-15 inches, and trucks serve 45-inch counterparts.
The simplest mechanisms for tire fittingare 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 the support of mechanics is provided, became an intermediate link. However, control actions are performed by the user himself. The operator must manually press the shaft, lowering the foot. Thus, the reversal of the installation site is performed.
Наиболее заметны высокие требования к физическому effort, if used semi-automatic tire machines for large vehicles. Automatic same models eliminate the same problems, allowing you to easily maintain not only cars with small trucks, but also trucks with buses. Such units are more often used in equipping automobile workshops, service centers, etc.
Such models are designed for mobility, simpleorganization of power supply and, of course, a small size of the wheels - up to 24 inches. Automatic installations are equipped with an electric motor that operates 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 power supply network, but also to the generator. That is, to perform repair work will be in the distance. Also, "light" tire machines 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 the high cost of electricity. In sets with such stands, lugs for clamping jaws, a grease container, a blade, a tire inflation gun, and other devices are usually provided.
On truck stands, wheels are located ontable not horizontally, but vertically. Moreover, they are held by a special retainer with four clips. 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. Both chamber and tubeless tires can be serviced, as well as models with a locking system.
Choose a tire changer for truckscars should be exerted on the load. Since the wheels differ from trucks by a large mass, the corresponding force is applied — about 1.2–1.5 tons. Moreover, the working process itself is not always safe, therefore remote control is provided for in modern models of such stands. Special consoles and controllers are installed on the working platform and connected to the mechanisms of the machine with removal.
Immediately it must be emphasized that it is advisablefocus on the manual type, as they are easier and safer to use. Three main components are required: a frame, a vertical riser and a length of metal pipe. As a frame, you can take two profile rectangular tubes, which are parallel to each other. They should be connected with a steel angle. Next, a vertical stand is attached to the frame, which will perform two functions: a carrier base with fastening and providing a place for fixing the wheel. Then a handle is introduced into the design that will enable the tire changer to be activated. The hands can be welded to the handle at the moment ready construction on the basis of a piece of pipe.
Как и любое гаражное оборудование, стенды для tire fitting regularly need technical support. Therefore, to count on long-term operation of the structure can only be in the case of proper maintenance. You should also prepare for minor technical issues. Home repair tire machines, for example, may be associated with violations in the hydraulic mechanism or electrical engineering. The power base rarely breaks, but in this part there may be defects at the joints of the functional parts. To prevent unpleasant nuances of using such equipment will help regular lubrication of the rubbing mechanisms and the correct handling of technological units of control and management.
