Based on years of research and development experience in the production of engineering machinery fasteners and global application experience, we have officially released a professional maintenance guide for Track plate bolts. We provide standardized and practical operation and maintenance instructions to global engineering machinery customers, helPing them scientifically extend the service life of bolts, reduce the risk of connection failures in walking systems, and ensure stable and efficient equipment operation.

Track plate bolts are the core connecting components of the walking system of construction machinery, which are subjected to alternating loads, vibration impacts, sediment erosion, and outdoor complex environmental erosion for a long time. Their performance directly affects the connection reliability of the track assembly and the safety of equipment operation. Improper daily maintenance and untimely repairs can easily lead to problems such as bolt loosening, corrosion, fatigue fracture, etc., which not only increase operation and maintenance costs, but may also pose safety hazards to operations. As a professional manufacturer of engineering machinery components settled in Yinzhou District, Ningbo in 2005, Yiteng Machinery has always focused on the actual pain points of customers' use, extending service value while outputting high-quality products. The release of this maintenance guide is an important measure for the company to deepen customer service and empower customer operation and maintenance capabilities.

The guide provides professional practical suggestions for the full life cycle operation and maintenance of track plate bolts: firstly, regular inspections and torque rechecks should be carried out to check the appearance of bolts for deformation, rust, and thread damage before and after daily operations. Pre tightening torque rechecks should be carried out on key parts of the Track Bolts according to the maintenance cycle to ensure that the torque value meets the working conditions and standards, avoiding long-term vibration and impact that may cause bolt loosening and retraction, and avoiding the risk of connection failure from the source; The second is to do a good job in cleaning and anti-corrosion protection. After each shift, promptly clean up the mud, slag, dust and other debris on the bolt surface and in the thread gap to avoid hard particles entering the mating surface, causing abrasive wear and accelerating thread loss. Regularly inspect the anti-corrosion layer on the bolt surface in high humidity, salt alkali and coastal working environments. If there is damage, timely apply protective coating to delay the corrosion process; The third is to standardize the disassembly and replacement standards. Special tools should be used to operate the disassembly and replacement of track plate bolts in a standardized manner. Violent tapping is prohibited to damage the threads and stress surfaces, avoiding hidden fatigue cracks in the bolts. Bolts should be replaced strictly according to the wear limit and fatigue cycle to prevent overdue service. When replacing, high-strength products of the same specifications from the original factory should be preferred to ensure dimensional accuracy and mechanical performance matching; The fourth is the selection and lubrication of suitable working conditions. Track plate bolts of corresponding strength levels are selected according to the operating scenario. High grade and high-strength models are preferred for heavy-duty mines and crushing sites. Adaptive extreme pressure lubricating grease is regularly added to the threaded mating parts to reduce friction and wear while improving anti loosening effect.
