Used Cat Excavator: 7 Checks Before You Buy
A used Cat excavator can help you add digging capacity without paying the full price of a new machine. It can also become an expensive problem if you focus only on the model year, paint, or hour meter. You may find two excavators of the same model with nearly identical hours, yet one is ready to work while the other needs an undercarriage, hydraulic repairs, and emissions-system service. The difference often comes down to how the machine was operated, maintained, stored, transported, and repaired. The market also changes quickly. In May 2026, inventory for used heavy-duty construction equipment in the United States was down 11.55% year over year. Used crawler excavator inventory fell 1.41% month over month, while crawler excavator…
Road Roller Operation Methods

Precautions for Used Machinery Operation
The core principle for operating used machinery is "Inspect Before Operation, Strict Load Control, and High-Frequency Maintenance." Due to the unknown history of the equipment, a more cautious approach than with new machines is mandatory. 1. In-Depth Inspection Before Commissioning Core Component Health Check: Focus on the engine (checking for smoke and oil leaks), hydraulic system (hose aging and pressure loss), and drivetrain (gear and bearing wear). Never operate a machine with known faults. Structural Integrity Verification: Carefully inspect load-bearing components such as the frame and boom for secondary welding, cracks, or straightening marks. Be vigilant for structural fatigue damage hidden by refurbishment. Documentation & Compatibility: Verify the nameplate serial number to confirm actual age. Ensure fuel grades and lubricant…

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. Personnel and Access Management Verification of Certification: Strictly inspect whether operators hold a valid Special Equipment Operation Certificate, ensuring it is within its validity period and matches the equipment category. Working without a certificate or with an expired license is strictly prohibited. Technical Disclosure: Confirm that written safety technical disclosures have been completed prior to work. Operators must be aware of underground utility distribution, emergency measures, and the day's risk points. Working Hour Compliance: According to the 2026 New Regulations, supervise that continuous operation time does not exceed 4 hours to prevent fatigue-related accidents.…
