# Comprehensive Guide to Loader Tire Maintenance: Extend Lifespan and Improve Efficiency

As the main equipment in construction machinery, the tire condition of loaders directly affects operational safety and economy. Changjian loaders are mostly used in high-intensity working conditions such as mining and construction, where tire wear is particularly severe. Mastering scientific tire maintenance methods can reduce tire replacement costs by more than 30% while significantly reducing downtime. The following is professional tire maintenance knowledge specifically compiled for Changjian loader users. I. Understanding the Tire Characteristics of Changjian Loaders (1) Typical specifications: commonly used large engineering tires such as 23.5-25 and 29.5-25 (2) Structural features: multi-layer steel wire belt + ultra-thick tread rubber (3) Working characteristics: large impact loads, tread temperature can reach above 80°C II. Standard Daily Inspection Procedure 1. Precise Tire Pressure Management Check in cold tire condition (after 4 hours of shutdown). Recommended values for different working conditions: crushed stone sites 0.35-0.4MPa; earthwork operations 0.3-0.35MPa; road transport 0.28-0.32MPa. Equip with a digital tire pressure gauge, with error controlled within ±0.02MPa. 2. Tread Depth Monitoring Use a depth gauge to measure the three main tread grooves. Limit wear standards: remaining tread on drive wheels <15mm; remaining tread on steering wheels <10mm. Judgment of abnormal wear types: sawtooth wear → check rim eccentricity; one-sided wear → adjust toe-in angle. III. Professional-Level Maintenance Techniques 1. Temperature Control Plan Stop for cooling after 2 hours of continuous operation. Infrared thermometer monitoring standards: tread <70°C (normal); 70-85°C (warning state); >85°C (stop immediately). 2. Tire Rotation Strategy Systematic rotation every 500 hours. The sequence is front left → front right → rear left → rear right → spare tire. Keep rotation records (date/working hours/position). 3. Emergency Wound Treatment Punctures <6mm: use professional vulcanized repair; sidewall damage: replace immediately, repair is prohibited. Establish a tire "medical record card" to record all repair history. IV. Response Plans for Extreme Working Conditions 1. Special Protection for Mining Operations Install tread protection chains; use cut-resistant compound rubber tires; check tread for embedded stones daily. 2. Maintenance in High-Temperature Seasons Avoid continuous operation from 13:00-15:00; appropriately reduce tire pressure by 0.02MPa; prepare tire cooling spray equipment. V. Advantages of Changjian Original Accessories The carcass steel wire layer adopts Bekaert technology; the tread rubber is added with a wear-resistant carbon black formula; the matching rims have undergone dynamic balance testing; a tire life tracking management system is provided. VI. Economic Management Recommendations Establish a single-tire cost accounting system; implement a tire "trade-in" policy; train professional tire maintenance technicians; apply an IoT tire pressure monitoring system. Practical case: A certain mining Changjian 956 loader, through standardized maintenance, increased tire service life from 1,800 hours to 2,800 hours, saving 23,000 yuan per tire. By implementing this scientific tire management system, Changjian loader tires can always be kept in optimal working condition, truly achieving the goal of reducing costs and increasing efficiency. It is recommended that a comprehensive tire health diagnosis be conducted once a month by professional service personnel to promptly identify potential problems.
