Municipal Engineering: Participates in urban road reconstruction and underground pipeline laying for earthwork operations and muck cleaning.

Frequently Asked Questions

Q: Why does the equipment's fuel consumption suddenly increase?

A: Possible causes include a clogged engine air filter, blocked fuel filter, hydraulic system leaks, or improper operation (e.g., frequent sudden acceleration, prolonged idling). Check and replace filters as needed, inspect hydraulic systems for leaks, and standardize operation habits.

Q: How to troubleshoot reduced digging force?

A: First, check hydraulic oil level and quality, replenishing or replacing as necessary. Then inspect hydraulic components (e.g., pumps, control valves) for faults such as stuck spools. Additionally, check for looseness or wear in working devices (e.g., boom, arm, bucket).

Q: What should I do if the equipment makes unusual noises?

A: Engine noises may indicate internal component wear, looseness, or poor lubrication--check oil level and belt tension. Hydraulic system noises may stem from pump wear or air in pipelines--inspect pump operation and vent pipelines. Track mechanism noises require checking crawler tracks, carrier rollers, and idlers for wear or loose connections. Stop operation immediately to prevent fault escalation.
