During the use, maintenance and repair of loader tires in summer, we recommend that you perform the following operations:
1. Use a special tire protection chain at the rock work site to reduce damage to tires and other materials.
2. The degree of wear of coaxial tires should be roughly the same, that is, the principle of simultaneous replacement should be adopted as much as possible. When the loader travels straight, due to the different rolling radius of the driving wheels on the two sides of the coaxial, the drive shaft main reducer has a differential speed (otherwise, the tires on both sides cannot make the loader travel straight), increasing the workload .
3. Under the same conditions, the degree of wear of the front axle drive tires is greater than that of the rear axle drive tires. You can periodically change the front axle tires to the rear axle. The front axle tires are as good as possible, usually more than 60%.
4. In order to reduce the cost of use, retreaded tires can be used for rear axle drive tires, and front axle drive tires should be avoided.
5. Before loading materials, the driver should bring the bucket close to the ground and remove the scattered materials in the work area, especially when the loader is working on the demolition site of the old building, it must be confirmed that it is not exposed. Reinforcement outlines foreign objects above the ground to prevent accidental injury to the tire.
6. If the tire crown is excessively worn, such as an exposed thread layer, the tire should be replaced in time. One is that the carcass of the tire is relatively complete at this time and can be refurbished, and the other is that the inner tube is complete, and only the outer tube can be replaced. If the tire is punctured without timely replacement of the tire, the inner and outer tires will be scrapped at the same time and can only be treated as waste tires.
7. During the process of replacing and repairing the tire, the driver should install the tire correctly to ensure that the inner tube is not wrinkled or contracted. When replacing the inner tube and the outer tube, in order to prevent the inner tube and the outer tube and the buffer belt from adhering to the wheel hub, an appropriate amount of talc can be applied to the inner cavity of the outer tube. Before applying talcum powder, a rag must be used to remove the water and sandstone in the tire cavity. Especially if there are particulate impurities such as sandstone between the inner tube and the outer tube, the inner tube will be damaged by repetition. extrusion. In addition, for the newly replaced inner tube, the lock nut connecting the bottom of the expansion nozzle to the inner tube is usually loose, and should be tightened with a wrench before installation.
8. For the puncture on the tire, in addition to using the inner cavity of the tire to place the mat in an emergency, you can also use a repair method such as fire repair to completely seal the puncture. Otherwise, untreated tire “wounds” will repeatedly squeeze the corresponding inner tube area, causing the inner tube to rupture.
9. After the loader exploded, it should be replaced on the spot. Otherwise, even short-distance driving may cause the inner tube to be scrapped and damage the outer tube, thereby shortening the service life.
10. The driver of the loader should regularly check whether the tire pressure meets the requirements, and appropriately adjust the tire pressure according to seasonal changes. The temperature in summer is high, and the tire pressure can be appropriately reduced. When inflating the tire, it must be confirmed with a barometer to avoid the danger of running.
11. The number of tires used in the loader inventory should not be excessive. Because the tire is a rubber product, as the storage time increases, the outside of the tire is easily oxidized and the service life is shortened. The longer the inventory time, the higher the degree of oxidation and the longer the storage time of the tire, the gray surface will appear on its outer surface. Buyers can also use this to determine the length of stock tires. In addition, tires should be stored in a dark and dry environment. High temperature conditions will also accelerate tire aging.
