At a time when construction machinery technology is changing with each passing day and market demand continues to rise, modern wheeled excavators, with their flexible and efficient characteristics, have occupied a pivotal position in many fields such as construction, mining, and road construction. For wheeled excavators, tires, as key components, are like the "foundation of their walking", which is directly related to the performance and service life of the whole machine. Therefore, mastering scientific tire maintenance methods has become an important issue that wheeled excavator users cannot ignore.

1. Careful selection, high-quality tires are the cornerstone

When purchasing a wheeled excavator, it is important to give priority to high-quality tires with excellent quality and strong adaptability. Generally speaking, tires from well-known brands have more advantages in quality control and reliability, so it is recommended that users choose those big brands with good reputation as much as possible. In addition, it is necessary to accurately select tires that are in line with actual working conditions in terms of load-bearing capacity, wear resistance, and heat resistance based on actual operating scenarios and needs. In this way, a solid foundation can be laid for the efficient operation of wheeled excavators.

2. Standardize operation and take care of tires in a methodical way

During the operation of wheeled excavators, strictly following relevant operating procedures and using tires in a standardized manner are the key to extending the service life of tires. Specifically, the following points should be paid attention to:

1. Avoid no-load and sudden operation: Try to avoid driving tires in an unloaded state, and try to reduce harsh operations such as sudden acceleration and sudden braking that cause great damage to tires. Sudden acceleration and sudden braking will cause the tires to bear huge impact and friction in an instant, accelerating tire wear and aging.

2. Prevent excessive lateral wear: Avoid sharp turns and avoid driving on rough roads for a long time. When making sharp turns, the side of the tire will bear a large lateral force, which can easily lead to increased lateral wear of the tire; and long-term driving on uneven roads will cause uneven contact between the tire and the ground, which will also accelerate tire wear.

3. Avoid mixing tires: Do not mix tires of the same type but different specifications. Tires of different specifications differ in rolling radius, load-bearing capacity, etc. Mixing will destroy the balance and stability of vehicle driving, causing the tires to wear faster and may even cause safety hazards.

3. Regular maintenance, timely troubleshooting and elimination of hidden dangers

The core of wheeled excavator tire maintenance is to detect and solve potential problems in a timely manner. Therefore, users must regularly conduct comprehensive and detailed inspections and maintenance of tires during daily use. The specific requirements are as follows:

1. Professional cleaning and meticulous care: Tires need to be cleaned and maintained regularly. According to actual conditions, professional tire cleaning fluid can be selected, combined with clean water and a soft brush to gently and meticulously clean the tires. After cleaning, use a fine sand cloth to gently wipe the tire surface to ensure that the tire surface is clean and dry, and remove impurities and corrosive substances that may be attached.

2. Accurate pressure measurement and standardized adjustment: It is crucial to accurately measure and reasonably adjust the tire pressure regularly. Ordinary barometers often have certain errors. To ensure the accuracy of the measurement, it is recommended that users purchase professional barometers and strictly adjust the tire pressure according to the standard values specified by the manufacturer. Appropriate tire pressure can not only increase the service life of the tire, but also ensure the driving safety and stability of the wheeled excavator.

3. Pay attention to wear and replace in time: Check the degree of wear of the tire regularly, especially pay close attention to the depth of the tire tread. Never wait until the tire tread is completely worn out before replacing it, because too shallow a tread depth will seriously affect the tire's grip and drainage performance, thereby endangering driving safety. Once it is found that the tire wear has reached a critical value, the tire should be replaced in time to ensure operational safety.

4. Proper storage and long-term protection from deformation

If the wheeled excavator needs to be out of service for a long time, the proper storage of the tire should not be ignored. The specific methods are as follows:

1. Reasonable storage to prevent deformation: The tire should be removed and properly stored in a flat and dry storage space. During storage, ensure that the tire is away from direct sunlight and chemical erosion to avoid tire aging due to ultraviolet radiation and chemical corrosion. In addition, to prevent the tire from long-term compression and deformation, if the storage time is long, the tire needs to be turned over in time to ensure that all parts of the tire are evenly stressed.

2. Protective treatment to delay aging: The tires can be phosphated and coated with anti-rust coating and other protective measures to effectively prevent rust and oxidation on the tire surface. This not only prolongs the service life of the tires, but also ensures that the tire performance is not affected when it is used again.

In summary, the tire maintenance work of wheeled excavators is of great significance and is a key link to ensure the safe and stable operation of the equipment. Users must attach great importance to it in actual work and formulate a long-term and systematic tire maintenance plan to ensure that the wheeled excavator always maintains the best working condition and completes various tasks efficiently and safely.
