As temperatures continue to drop, the Frost's Descent solar term brings increased challenges for winter operation of excavator attachments. To ensure equipment maintains efficient and stable performance in low-temperature environments, industry experts have proposed targeted maintenance and operational strategies, offering professional guidance for winter upkeep of construction machinery.
First, regarding attachment maintenance, low temperatures cause significant thermal expansion and contraction in metal components, increasing the risk of loosening. Therefore, a systematic structural inspection of excavator attachments should be conducted around the Frost's Descent period. Key focus areas include tightening easily loosened parts such as bolts, pins, and nuts to ensure all components fit snugly and prevent faults caused by increased gaps. Additionally, low temperatures significantly impact seals and lubrication systems. Rubber seals can harden and fail, necessitating timely replacement as needed. Lubricants should be selected based on the operating environment, opting for low-temperature viscosity grades or additives that improve flow properties to maintain lubrication performance. As the core of attachment operation, the hydraulic system requires close monitoring of oil level and quality. If contamination, degradation, or insufficient levels occur, promptly replace or replenish the fluid. Conduct a hydraulic system flush as needed to maintain stable power output. Secondly, ensuring winter construction safety hinges on operator training. Operators must master specialized winter techniques for handling frost-covered ground and reduced hydraulic responsiveness at low temperatures. This includes maintaining stability of attachments like buckets and breakers on frozen surfaces, and adjusting operating pressure and speed based on soil conditions and temperature. Safety awareness training should also emphasize cautious operation on slippery surfaces to prevent slips, falls, and injuries. Prior to operations, conduct thorough site assessments and develop reasonable work plans to ensure safe, orderly construction throughout the process. Furthermore, experts offer practical daily maintenance tips for winter attachments. Before daily operations, perform visual inspections of attachments for cracks, deformation, weld fractures, or loose connections. Post-operation cleaning is equally crucial. Accumulated dirt and debris accelerate wear and tear, potentially infiltrating internal mechanisms. Timely removal is essential to maintain clean surfaces and critical components. After working in damp or wet conditions, thoroughly dry surfaces or apply rust inhibitors to prevent oxidation. Conduct thorough internal inspections to guard against moisture ingress causing corrosion and mechanical jams.
As colder seasons approach, scientifically maintaining excavator attachments not only extends their service life but also ensures winter construction safety and efficiency. Through enhanced inspections, scientific maintenance, and professional operation—all supported by coordinated efforts—construction machinery can maintain stable performance in severe cold, providing reliable support for winter construction projects.
