Covers all core resources of used construction machinery, focusing on two main categories - used diggers and second hand loaders, with a total of 55 mainstream models. All equipment undergoes 28 professional inspections (including key parts such as engines, hydraulic systems, and structural components), providing complete maintenance records and machine age traceability, with cost-effectiveness far exceeding the industry average. On-site test runs are supported, creating a one-stop used construction machinery procurement service system of "machine selection - inspection - purchase - after-sales" for customers.
