The Scientific Use of Loaders Plays an Important Role in the Maintenance of Loader Tires
1. Loader tires must be reasonably matched
The tires on the front, rear, left and right of the conventional loader tires must be reasonably matched, with the same brand, specification, structure and tire pattern, and the load must be the same. In addition, it should be noted that the radial and bias tires must not be mixed together. Otherwise, the result is that individual tires are severely worn, causing premature damage or even puncture. In addition, if conditions permit, it is best to arrange tire replacement in winter or spring, and install it according to the specified rotation direction. The best solution is to replace all of them or replace them symmetrically. If it is necessary to use old tires with two tires, the wear should not exceed 5mm. Generally, the front wheel is the first tire to be replaced.
2. The air pressure of the loader tires should remain stable
The air pressure of the loader tires remains consistent and normal, the pressure is normal and stable, the bearing capacity is uniform, and the wear is normal. If the pressure is low, the strength of the tire will decrease, and the deformation will be serious after loading. Not only the shoulder wear is serious, but the tire heat is easily caused, which may cause cord damage and carcass delamination. On the contrary, if the air pressure is too high, the tire will have high hardness and low elasticity, the cord will be broken, the tire crown will wear, and the load per unit area will increase, and the tire burst rate in summer will be very high. Therefore, the tire pressure should be checked regularly.
3. The scientific use of loaders plays an important role in the maintenance of loader tires
Loader starts and stops: Start slowly. Excessive starting is the biggest cause of tire wear of the loader, and braking is the same. Therefore, according to the road conditions, use exhaust brakes instead of brakes, and avoid emergency braking unless there are special circumstances.
Driving speed also has a great influence on the life of tires. In actual use, speed and load have the same meaning. In some cases, speed is even more important. In order to obtain the best results, if the vehicle speed is higher than the tire's rated speed, the transportation load should be appropriately reduced; if the vehicle speed is lower than the tire's rated speed, the transportation load can be appropriately increased. Because the tire is in contact with the ground, friction, and the carcass vibrates in actual use, the circumferential and lateral deformations are aggravated with the increase of vehicle speed, and the tire temperature will rise sharply, causing the tire to burst.
Loader parking area: This is the detail and the most easily overlooked place, so this item once again emphasizes that the first thing to do is to choose a flat and clean ground, avoid rocks, exposure, and frozen water, park for a long time, use brackets, and tires up to the standard. The air pressure is 90%, and the loader tires are cleaned and maintained to prevent aging.
