Changjian Loader Tire Maintenance Guide: Extend Lifespan, Boost Efficiency

As a mainstay piece of equipment in the construction machinery sector, the condition of a loader's tires directly impacts operational safety and economic efficiency. Changjian loaders are frequently used in high-intensity working conditions such as mines and construction sites, where tire wear is particularly severe. Mastering scientific tire maintenance methods can reduce tire replacement costs by more than 30% while significantly decreasing downtime. The following is professional tire maintenance knowledge compiled specifically for Changjian loader users. I. Understanding the Characteristics of Changjian Loader Tires (1) Typical Specifications: Commonly uses large engineering tires such as 23.5-25 and 29.5-25. (2) Structural Features: Multi-layer steel belt construction plus an extra-thick tread compound. (3) Operating Characteristics: Subject to high impact loads, with tread temperatures capable of exceeding 80°C. II. Standard Daily Inspection Procedures 1. Precise Tire Pressure Management Check when tires are cold (at least 4 hours after stopping). Recommended pressures for different conditions: 0.35-0.4 MPa for rocky/gravel sites; 0.3-0.35 MPa for earthmoving operations; 0.28-0.32 MPa for highway transport. Use a digital tire pressure gauge, keeping the margin of error within ±0.02 MPa. 2. Tread Wear Depth Monitoring Use a tread depth gauge to measure the three main grooves. Wear limits: Drive tires must be replaced when remaining tread depth is less than 15mm; steering tires when less than 10mm. Diagnosing abnormal wear patterns: Sawtooth wear indicates a need to check rim eccentricity; one-sided wear requires adjusting the toe-in angle. III. Professional-Level Maintenance Techniques 1. Temperature Control Plan Stop and allow tires to cool after 2 hours of continuous operation. Monitoring standards using an infrared thermometer: Tread temperature below 70°C (normal); 70-85°C (warning status); above 85°C (stop immediately). 2. Tire Rotation Strategy Rotate tires systematically every 500 hours. The sequence is front-left → front-right → rear-left → rear-right → spare tire. Keep detailed rotation records (date/hours/position). 3. Emergency Puncture Repair For punctures smaller than 6mm: Use professional vulcanized repair. For sidewall damage: Replace the tire immediately; repairs are prohibited. Maintain a tire "medical record" documenting all repair history. IV. Response Plans for Extreme Working Conditions 1. Special Protection for Mining Operations Install tread protection chains; use cut-resistant compound tires; check for stones embedded in the tread daily. 2. Maintenance During High-Temperature Seasons Avoid continuous operation between 13:00 and 15:00; reduce tire pressure slightly by 0.02 MPa; keep tire cooling spray equipment on hand. V. Advantages of Changjian Genuine Parts The carcass steel cord layer utilizes Bekaert technology; the tread compound incorporates a wear-resistant carbon black formula; matching rims undergo dynamic balance testing; a tire lifespan tracking and management system is provided. VI. Economic Management Recommendations Establish a per-tire cost accounting system; promote a tire "trade-in" policy; train specialized tire maintenance technicians; implement an IoT-based tire pressure monitoring system. Practical Case: A Changjian 956 loader at a mine site extended its tire service life from 1,800 hours to 2,800 hours through standardized maintenance, saving 23,000 yuan per tire. By implementing this systematic tire management protocol, Changjian loader tires can be maintained in optimal working condition, effectively achieving the goals of cost reduction and efficiency enhancement. It is recommended that a comprehensive tire health diagnostic be performed monthly by professional service personnel to identify potential issues early.
