Excavator Operation Inspection Points
During excavator operations, supervising engineers must focus their safety patrols and inspections on four core dimensions: Personnel Qualification, Equipment Status, Working Environment, and Operational Compliance. 1.

Maintenance & Repair of Used Motor Graders
Upon purchasing a used motor grader, the core strategy must be "Comprehensive Inspection, Proper Break-in, and Strict Maintenance." Due to the unknown history of previous usage, it is critical to focus on hidden wear and oil contamination. Systematic maintenance is required to restore performance and extend service life. I.

One may have spent its life loading loose soil with careful operators and regular servicing. The other may have hammered rock, worked in salt, missed oil changes, and received fresh paint shortly before being listed. The hour meter alone cannot reveal that difference. Key takeaway: You are not simply buying a used Cat excavator. You are buying its previous workload, maintenance habits, hidden…
