What should be noted in the daily maintenance of mining excavators used in coal mines（haoyun）

The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. will provide the following explanation.

The daily maintenance of excavator loaders used in coal mines is the key to ensuring long-term stable operation, reducing failure rates, and extending service life of the equipment. Haoyun Heavy Industry has the following important points to pay attention to during daily maintenance:

1. Cleaning and inspection:

External cleaning: Regularly remove coal dust and dirt from the surface of the equipment, especially in the radiator, fan, and engine areas, to maintain good heat dissipation.

Inspect worn parts: Regularly check the wear of easily worn parts such as buckets, digging arms, tracks, or tires, and replace severely worn parts in a timely manner.

2. Maintenance of hydraulic system:

Hydraulic oil inspection: Haoyun Heavy Industry regularly checks the cleanliness and oil level of hydraulic oil, promptly replaces contaminated hydraulic oil and filter elements, and maintains the cleanliness and lubrication of the hydraulic system.

Hydraulic pipeline inspection: Check for leaks, wear, or damage to the hydraulic pipelines and joints to ensure the sealing and safety of the hydraulic system.

3. Electrical system inspection:

Battery inspection: Regularly check the charging status and connection of the battery to ensure the stable operation of the electrical system.

Wire and connector inspection: Check whether the wires and connectors are damaged or loose, repair or replace them in a timely manner, and prevent electrical faults.

4. Lubrication and fastening:

Lubrication point maintenance: Regularly lubricate various lubrication points of the equipment, including bearings, gears, and chains, to reduce component wear.

Fastener inspection: Check whether the fasteners on the equipment are loose, such as screws, nuts, etc., and tighten them in a timely manner to avoid damage to the components due to looseness.

5. Cooling system inspection:

Coolant inspection: Regularly check the level and quality of the coolant, replenish or replace it in a timely manner, and ensure the normal cooling of the engine.

Cleaning of radiator: Regularly clean the dust and debris on the radiator to maintain good heat dissipation effect.

6. Operation and safety inspection:

Operation panel inspection: Ensure that all indicator lights and buttons on the operation panel are working properly.

Safety device inspection: Check the safety devices of the equipment, such as emergency stop buttons, safety barriers, etc., to ensure that they are functioning properly.

7. Records and Reports:

Maintenance records: Detailed records of the date, content, and issues discovered during each maintenance, facilitating tracking of equipment status and planning for future maintenance.

Fault report: Timely report any discovered faults or abnormal situations to ensure that problems are resolved in a timely manner.

By following the above maintenance guidelines, it is possible to effectively maintain the good operating condition of mining loaders, reduce downtime caused by equipment failures, and improve production efficiency and safety.
