Daily maintenance and precautions of excavators
Excavator, an indispensable construction machinery in construction projects, is directly related to the progress and quality of the project. According to the research of Lingong, up to 70% of the failures are due to improper operation and maintenance. Therefore, in order to ensure the continuous and stable operation of the excavator and prolong its service life, the maintenance measures of the system are particularly important. The purpose of this article is to provide readers with a detailed excavator maintenance guide, covering all aspects of daily inspection, regular maintenance and professional maintenance.
Clean the heat dissipation area: Before and after daily use, be sure to remove dust and debris from the excavator’s heat dissipation area to ensure that its performance is not affected.
Check the antifreeze: Regularly review the antifreeze in the sub tank to make sure it is sufficient and shows no signs of spoilage.
Lubricating oil inspection: Carefully check the amount of lubricating oil on the excavator to ensure that the oil level is maintained within the normal range.
Hydraulic system evaluation: The pressure of the hydraulic system is measured, and at the same time, it is determined whether the hydraulic oil needs to be replaced.
Electrical System Inspection: Thoroughly review the integrity of the electrical wiring and confirm that the power plug is securely plugged in.
Regular maintenance points
Oil and filter changes: Follow the manufacturer’s recommendations to change the oil and filter every 500 hours to ensure continuous and stable engine operation.
Hydraulic oil inspection and replacement: The hydraulic system is a key part of the excavator, and the quality and quantity of hydraulic oil need to be evaluated regularly. If necessary, it should be replaced, especially after the installation of the breaker, and the replacement cycle should be shortened to maintain the normal operation of the hydraulic system.
Inspection and maintenance of the transmission system: The transmission system is very important to the excavator, and the wear and tightness of the four wheels should be regularly reviewed and maintained accordingly. At the same time, the gear oil of the travel reducer should be changed every 500 hours to prevent abnormal wear.
Inspection and maintenance of electrical system: The safety and reliability of the electrical system should not be ignored, and the working status of wires, switches and other components should be checked regularly.
Warm reminder: Do not stack heavy objects in the battery box, this may cause serious safety hazards.
In order to keep the pin of the working device running smoothly, it is recommended to lubricate once after each working shift. The slewing support should be lubricated every 250 hours to prolong its service life.
