The used construction machinery market is currently in a phase of "rising volume and stable prices." Domestic transaction prices for mainstream used excavators and loaders have generally rebounded by 3% to 8% compared to the same period last year, and the share of export orders has grown from less than 20% two years ago to nearly 30%. If you are planning to sell old machines or add a few units, now is a relatively good window, but you must pay close attention to condition inspections and parts sources.
Industry Background: Stock Renewal Coupled with Export Pull
Domestic construction machinery ownership has passed its high-growth stage, and a large number of machines sold between 2016 and 2020 are entering a concentrated replacement period. Taking 20-ton class used excavators as an example, Komatsu PC200 and Caterpillar 320 units registered in 2019 currently trade at terminal prices between RMB 280,000 and 450,000, depending on working hours, undercarriage, and hydraulic system condition. Meanwhile, infrastructure projects in Southeast Asia, Africa, and the Middle East have strong demand for used bulldozers and loaders. A well-conditioned used loader (such as LiuGong 856 or Lingong 953) can fetch an export price 10% to 15% higher than in the domestic market.

The mining truck segment is somewhat unique. With tightening environmental and emission requirements in domestic mining areas, a batch of non-road China III and China IV mining trucks is accelerating its flow overseas. For models like Tongli TL875 and XCMG XDM series, used prices fluctuate roughly between RMB 600,000 and 1,200,000 depending on payload and engine overhaul condition.
Current Analysis: Which Models Circulate Quickly and Which Are Slow-Moving
- Used Excavators: The 20–30 ton class is the most sought-after. Domestic brands Sany and XCMG have notably improved their value retention, while imported Caterpillar and Komatsu still command a brand premium. Mini excavators under 10 tons face fierce competition, transparent pricing, and thin margins.
- Used Loaders: Mainstream 5-ton models turn over fastest. Small loaders under 3 tons are driven by rural infrastructure, but condition varies widely, and buyers generally require hydraulic oil test reports.
- Used Bulldozers: Shantui SD16 and SD22 circulate steadily. Dry-ground machines sell better than swamp machines, and machines with complete overhaul records command a premium of about 5%.
- Mining Trucks: Rigid mining trucks and wide-body trucks are diverging. Wide-body trucks circulate more slowly due to policy restrictions, while rigid mining trucks enjoy firm export demand.
According to frontline transaction data from Sanqi Machinery, dealers with OEM parts supply capabilities shorten the average transaction cycle by 7–10 days. Buyers increasingly value one-stop solutions of "equipment + parts + after-sales," squeezing the space for middlemen who merely resell equipment.
Purchasing Advice: Check the Three Major Components First
Whether you are using the machine on a domestic job site or planning to export it, the core of buying used construction machinery comes down to three things: engine, hydraulic pumps and valves, and undercarriage. For engine parts, check whether it has undergone an OEM overhaul and whether there are signs of oil burning. For hydraulic parts, focus on testing main pump pressure and distribution valve response; on-site action tests are best. For the undercarriage, check track link wear and carrier roller clearance on excavators, and frame articulation pin play on loaders.
For export orders, two additional points require attention: first, whether emission standards meet the destination country's requirements. Some African countries accept China II and China III, while the EU has higher thresholds. Second, accompanying documents, including OEM inspection reports, maintenance records, and export customs clearance documents. Sanqi Machinery provides bilingual Chinese-English inspection reports and global logistics solutions during the export process to reduce buyers' customs clearance risks.
Precautions: Avoid Three Types of Traps
- Refurbished machines passed off as original: Cases of full-body repainting and replaced nameplates still exist. It is advisable to verify whether the engine number and frame number match.
- Odometer fraud: Do not rely solely on the instrument panel. Make a comprehensive judgment based on hydraulic oil cleanliness, cab wear, and track shoe thickness.
- Substandard parts: Aftermarket hydraulic parts are cheaper but have shorter service lives. For export equipment, it is recommended to use OEM parts or well-known brand replacement parts.
FAQ
What are the current prices for used excavators?
A 20-ton class domestic used excavator costs about RMB 180,000 to 300,000, while imported brands cost about RMB 280,000 to 450,000, depending on year, working hours, and hydraulic system condition. Machines with inspection reports are priced slightly higher.
What procedures are required for exporting used construction machinery?
Generally, a certificate of origin, inspection report, export customs declaration, and ocean freight booking are required. Some countries also require emission certification. It is advisable to find a dealer with import-export experience to handle these procedures.
How can I judge the condition of a used loader?
Focus on the frame articulation pin clearance, whether the transmission shifts smoothly, and whether there are metal particles in the hydraulic oil. It is best to test the machine for more than half an hour and observe oil temperature and action speed.
Are parts for used bulldozers easy to buy?
Parts for mainstream brands such as Shantui and Xuangong are in ample supply, and both OEM parts and brand replacement parts are easy to procure. For imported models such as Caterpillar and Komatsu, OEM parts take slightly longer but the channels are stable.
What should be noted in used mining truck transactions?
Confirm the engine overhaul records, check the frame for cracks, and assess remaining tire life. For exported mining trucks, also verify the destination country's restrictions on payload and emissions.
