What Work Should Be Done in the Use of Loader Tyres and Later Maintenance?
For the use of loader tyres and later maintenance, what work do loader tire manufacturers think should be done? It is suggested that during the use, maintenance and repair of loader tyres, the following aspects should be done well.
1. Matters needing attention in the work of loader tyres
Use special loader tire protection chains on rocky work sites to reduce damage to tires from rocks and other materials. The degree of wear of coaxial tires should be roughly consistent, that is, the principle of simultaneous replacement should be adopted as much as possible.
When the loader is running in a straight line, due to the difference in the rolling radius of the driving wheels on both sides of the coaxial axle, the main reducer of the drive axle produces a differential speed (otherwise the tires on both sides cannot make the loader drive in a straight line), which increases the work of the differential burden.
In view of the fact that under the same conditions, the wear degree of the front axle drive tires is greater than that of the rear axle drive tires, the front axle loader tyres can be replaced by the rear axle regularly.
The front axle drive tires should be kept as good as possible, generally more than 60%. In order to reduce the cost of use, rear axle drive tires can be retreaded tires, while front axle drive tires should be avoided.
Before shoveling materials, the driver should put the bucket close to the ground and clean up the scattered materials in the work area. Especially when the loader is working on the old building demolition site, it must be confirmed that there is no exposed steel bar contour on the work site. foreign objects out of the ground to prevent accidental damage to the loader tyres.
2. How to replace the loader tyres correctly?
If the crown of the outer tire has been excessively worn, such as a partially exposed layer of thread, the outer tire should be replaced in time. One, the carcass of the outer tire remains relatively intact at this time and can be refurbished.
Two inner tubes remain intact, only changing the cover tire gets final product. Once the tire is blown out due to untimely replacement, the inner and outer tires will be scrapped at the same time, and they can only be treated as waste tires, which is not worth the candle.
During the process of changing and repairing tires, the driver should install them correctly to ensure that the inner tube of the loader tire is free from folding and clamping. When replacing the inner and outer tires, in order to prevent the inner and outer tires and the pad belt from sticking to the wheel hub, you can apply an appropriate amount of talcum powder to the inner cavity of the outer tire.
Before applying talcum powder, the accumulated water and sand in the inner cavity of the tire must be cleaned with a rag, especially if particles such as sand and stone are mixed between the inner and outer tires, the inner tire will be damaged due to repeated extrusion.
In addition, for the newly replaced inner tube of the loader tire, the lock nut connected to the inner tube at the bottom of the inflation nozzle is generally loose, and should be tightened with a wrench before installation.
In the case of penetrating wounds in tires, in addition to the method of laying pads in the inner cavity of the tire under emergency conditions, repair methods such as fire repair that can completely seal the penetrating wounds must be used.
Otherwise, the untreated tire "wound" will repeatedly squeeze the corresponding inner tube parts, resulting in inner tube damage. The loader tire manufacturer believes that after the loader tire blows out, it should be replaced on the spot, otherwise, even if it is driven for a short distance, it may cause the inner tube to be scrapped, cause damage to the outer tire, and reduce the service life.
