Maintenance & Operation Suggestions

Based on years of on-site maintenance experience, our engineers provide the following practical suggestions to extend component service life and avoid common faults (engineer’s practical tips): 1. For DQ027 series structural components (such as DQ027.23.03.00Ⅱ Main Torque Absorbing Beam), check for deformation every 4 months, and avoid overloading the equipment beyond the rated load (80 tons); 2. Nord-Lock Lock Washers should be replaced every 12 months, and do not reuse old washers, as the serrated structure will wear out after use, reducing anti-loosening performance; 3. 1200390523 Sealing Oil Seal should be checked for damage every month, and avoid using sharp tools during installation to prevent scratching the seal; 4. For 1300127459 Open Groove Ball Bearing, add lubricating grease every 3 months (use lithium-based grease), and clean the bearing surface to avoid dust accumulation; 5. DQ027.12.06 Main Shaft should be calibrated for rotation accuracy every 6 months, ensuring the error is within 0.03mm. Following these suggestions can reduce component failure rate by 65% and extend service life by 2-3 years.
