Inspection Points for Underground Loaders After Long-Term Parking

After being parked for a long time, underground loaders are easily affected by the complex underground environment. Therefore, a thorough inspection must be carried out before reuse to ensure safe and reliable operation.

1. Appearance and Structural Inspection:
Carefully check whether the loader’s body has any obvious deformation or damage, especially on working components such as the bucket and boom, to see if there are cracks or fractures. Inspect bolts and nuts at connection points to confirm they are not loose or missing. Loose ones should be tightened promptly, and missing ones should be replaced immediately. At the same time, check the tires for wear and air pressure. If tires are damaged or underinflated, they must be replaced or inflated in time.

2. Engine Inspection:
Open the engine hood and check the fluid levels of the engine, including engine oil, coolant, and hydraulic oil, ensuring that the levels are within the normal range. If fluids are insufficient, refill them to the specified level; if fluids are deteriorated (e.g., engine oil is blackened or has an abnormal odor, coolant is turbid, etc.), they should be replaced with new ones. Check the tension of the engine belts, as both excessive looseness and tightness will affect normal engine operation. Adjust to the proper tension as needed. Additionally, ensure that the intake and exhaust systems are clear, without blockages or damage.

3. Electrical System Inspection:
Check whether the battery is adequately charged; if not, recharge or replace the battery. Inspect all electrical connections to ensure they are secure and free from damage or aging, preventing short circuits or leakage accidents. Test the lighting system and instrument panel to confirm that lights are functioning properly and that instrument readings are accurate.

4. Brake System Inspection:
Since the brake system is critical to the driving safety of underground loaders, it requires special attention. Check the brake fluid level and quality; refill if insufficient and replace if deteriorated. Test the brake pedal’s travel and braking force to ensure the brakes are sensitive and reliable.
