I. Immediately Stop High-Load Operations
Turn off the vibration function, keeping only the driving mode active to reduce the impact of vibration on the system.
Reduce engine speed to a low to medium gear, avoiding continuous full-load operation. Gradually shut down the machine after the operating conditions stabilize.
Slowly drive away from high-resistance work areas, such as hard rock layers or collapsible loess areas, avoiding forced construction.
II. Perform Safe Shutdown and Natural Cooling
Let the machine idle for 5–10 minutes before shutting it off to prevent damage to the turbocharger due to thermal shock.
Wait at least 30 minutes for natural cooling, ensuring the water temperature is <85°C and the hydraulic oil temperature is <60°C. Do not add cold water directly or use forced cooling.
III. Quickly Inspect High-Risk Components
Listen to the vibration bearing: Use a stethoscope to check for any "humming" or "clicking" noises. If any abnormality is found, stop using the bearing immediately.
Inspect the steel wheel welds: Pay special attention to the hub connection and reinforcing rib area for signs of cracks.
Inspect the hydraulic system: Observe whether the hydraulic fluid is black, has a burnt smell, or contains metal shavings; check for leaks at pipe joints.
IV. Set up on-site warnings and report the incident.
Turn on hazard lights and place warning signs to prevent other equipment from approaching.
When working on ramps, secure the steel wheels (if using triangular blocks) to prevent slippage.
Notify the site supervisor immediately; if necessary, suspend work and await professional assistance.
