I. Immediately Stop the Machine and Allow it to Cool Naturally
Do not shut off the engine immediately after overload. Let it idle for 5-10 minutes to avoid thermal shock damage to the turbocharger and oil circuit.
Wait at least 30 minutes for natural cooling, ensuring the coolant temperature is <85°C and the hydraulic oil temperature is <60°C before proceeding with further operations.
II. Replace Core Fluids to Restore System Performance
Replace engine oil and filter: Overload causes high-temperature oxidation of the engine oil, resulting in loss of lubrication; it must be completely replaced.
Replace hydraulic oil and filter element: To prevent deteriorated fluids from causing valve sticking or pump wear.
Check transmission fluid condition: For traction impact rollers, ensure the gear oil is not deteriorated and top up to the standard level.
III. Focus on Inspecting Vulnerable Components
Vibration bearing: Use a stethoscope to check for any abnormal "humming" or "clicking" noises. Replace immediately if any abnormality is found.
Steel Wheel Welds: Visually inspect or use an ultrasonic flaw detector to check for microscopic cracks at the wheel hub connection and reinforcing rib areas.
Shock Absorber: Check for cracks in the rubber blocks and oil leaks from the hydraulic buffer cylinder to ensure effective damping.
IV. Comprehensive Cleaning and System Reset: Clean oil, dirt, and other contaminants from the radiator, engine compartment, and steel wheels to ensure efficient heat dissipation and operational balance.
Reset instrument parameters, clear non-fatal fault codes, and confirm that the EMS system has returned to normal monitoring status.
