Ensuring the optimal performance and longevity of wheeled excavators requires strict adherence to tire maintenance standards. This article provides a comprehensive guide covering tire inflation, abnormal wear prevention, correct tire selection and installation, regular tire rotation, temperature control, and proper tire storage.
-
Tire Inflation and Inspection: Wheeled excavators must strictly adhere to tire inflation standards. After inflation, a thorough inspection for leaks in all parts is essential. Regularly check tire pressure using a pressure gauge to ensure it meets the recommended standards. The habit of measuring pressure with a gauge should be cultivated, avoiding reliance on visual assessments. Maintaining a certain level of tire elasticity under specified loads ensures deformation within the prescribed range, contributing to the vehicle's stability and comfort. It is advisable to inflate spare tires relatively higher to prevent gradual deflation over time.

Preventing Abnormal Wear: Abnormal tire wear is a common concern for operators, caused by factors such as excessive or insufficient tire pressure, overloaded operations, poor wheel alignment, and inexperienced driving leading to brutal maneuvers. Correct tire selection, installation, and protection against external damage are crucial for extending tire lifespan. Analyzing the reasons for abnormal wear and implementing corresponding measures is essential for preventing premature wear, reducing costs, and ensuring safe and efficient operation.

Correct Tire Selection and Rotation: Tires play a pivotal role in the performance of wheeled excavators, directly impacting traction, maneuverability, stability, safety, comfort, and overall economic efficiency. The article emphasizes the importance of correct tire selection and installation, highlighting the necessity of using tires with the same brand, structure, and performance on the same machinery. Proper rotation methods, such as cross rotation for vehicles on arched surfaces and cycle rotation for those on flat roads, are essential for even tire wear.
-
Temperature Control: Controlling tire temperature during operation is crucial. High temperatures due to friction and deformation can lead to increased internal tire temperatures and air pressure. In such cases, avoiding methods like deflating or reducing pressure is recommended. Pouring water on hot tires should also be avoided to prevent accelerated tire damage. Resting in shaded areas when temperatures are high ensures tire temperature reduction before continuing operation. Safe coasting practices during stops and careful placement of vehicles, especially when loading overnight, contribute to overall tire health.
-
Proper Tire Storage: To avoid damage, tires should be stored away from sunlight, oils, acids, flammable substances, and chemically corrosive materials. Storing all tires in a cool, dry, and dark indoor space in an upright position is crucial. Flat laying, stacking, or hanging in a cross shape is strictly prohibited. The storage period should not exceed three years. If inner tubes require separate storage, they should be inflated with an appropriate amount of air and not folded, laid flat, or stacked. When not stored separately, they should be placed inside the outer tire with sufficient inflation.
-
Winter Considerations: In extremely cold regions, where low temperatures affect tire rubber properties, precautions such as smooth starts after overnight parking and careful maneuvers on icy surfaces are emphasized. Placing wooden boards or sand under tires during extended outdoor parking prevents tires from freezing to the ground.
By following these guidelines, wheeled excavator operators can significantly enhance tire performance, reduce maintenance costs, and ensure safe and efficient machine operation.
