If you are planning to purchase used construction machinery through a platform, the safest approach is: first confirm the equipment inspection report and the operating hours of core components, then use platform escrow payment, settle the balance before container loading, and write after-sales terms into the contract. The current process at Sanqi Machinery · 83777.cn is roughly divided into five steps—machine selection, inspection, contract signing, payment, and delivery. Each step has corresponding documentation and milestone controls. The following is presented in actual business order.
I. Equipment Screening and Inspection Basis Before Procurement
The used excavators, used bulldozers, used loaders, and mining trucks sold on the platform mainly come from two sources: first, retired machines from large domestic mines and infrastructure enterprises; second, first-hand vehicles from auction houses in Japan and Europe. Sanqi Machinery performs three basic inspections on each machine:
- Engine parts inspection: including cylinder pressure, turbocharger clearance, and oil pan metal debris analysis to determine whether a major overhaul has been performed;
- Hydraulic system inspection: main pump pressure, flow, pilot pressure, as well as leakage and abnormal noise in hydraulic parts;
- Undercarriage and structural components: track shoe thickness, roller wear, boom and arm welds, and slewing bearing clearance.
The inspection report includes photos and videos of key areas, and buyers can request additional specific angles. For example, for a 2019 Caterpillar 320D2 with 6,000–8,000 hours, the domestic market price is about RMB 380,000–520,000; for a Komatsu PC200-8 of the same tonnage with 8,000–10,000 hours, quotes are concentrated at RMB 300,000–420,000. In terms of used bulldozers, Shantui SD16 and Caterpillar D6G are the models with the most export inquiries, and a D6G in good condition typically has an FOB price in the range of RMB 450,000–700,000.
II. Payment Methods and Milestone Control
Platform procurement does not follow a “full payment before shipment” model. The standard practice is a deposit to lock the machine and settlement of the balance before container loading. The specific ratio varies according to the equipment amount and export destination port:
- Domestic transactions: 30% deposit, 70% balance after satisfactory inspection, supporting corporate transfer and bank acceptance;
- Export transactions: 30%–50% deposit, balance paid before container loading or against a copy of the bill of lading, commonly by T/T wire transfer;
- Large mining trucks or bulk purchases: L/C or third-party escrow can be negotiated, but the cycle will be extended by 7–10 working days.
It should be noted that any request for “full payment to a personal account” or “pay in full before inspection” can basically be judged as unreliable. The significance of platform escrow is that the deposit can be refunded if the inspection is not passed, and this must be written into the procurement contract.
III. Logistics Delivery and Export Operations
The logistics method for exporting used construction machinery mainly depends on the destination port and machine dimensions. Small excavators (6–13 tons) and loaders mostly go by 40-foot high-cube or flat-rack containers, departing from Shanghai, Tianjin, and Qingdao ports, with sea freight time to major Southeast Asian ports of about 7–15 days; mining trucks and large bulldozers go by breakbulk or Ro-Ro vessels, with routes to Africa and South America usually taking 25–40 days. At the delivery stage, Sanqi Machinery provides:
- Export customs declaration, certificate of origin, container loading photos and videos;
- Equipment cleaning, oil draining, and power disconnection to meet destination country quarantine requirements;
- List of accompanying accessories, including recommended spare parts inventory for vulnerable hydraulic parts and engine parts.
Some countries in the Middle East and Africa require equipment to be no more than 8 years old, while Southeast Asia is relatively more relaxed, but the invoice amount and actual cargo value must match during customs declaration, otherwise customs clearance at the destination port can easily be delayed. These details must be confirmed with the platform before signing the contract.
IV. Scope of After-Sales Service Support
After-sales service for used equipment is not like the full-machine warranty for new machines, but platforms generally provide three types of support: first, if core components (engine, hydraulic main pump) have non-human-caused failures within 7 days after arrival, repair compensation can be negotiated; second, original parts supply—Sanqi Machinery keeps hydraulic parts and engine parts for Caterpillar, Komatsu, Hitachi, and Volvo in stock, with domestic shipment within 48 hours, and export parts shipped by air or sea consolidation depending on the destination country; third, technical support through video guidance to help local operators troubleshoot common faults. For repairs beyond the warranty period, parts are charged according to the quotation list, and labor costs are calculated separately.
V. Frequently Asked Questions (FAQ)
Q: How can I tell whether the hours on a used excavator have been rolled back?
A: Check the wear on the cab floor, the degree of seat collapse, the date on the hydraulic pump nameplate, and the historical records of the ECU, then combine these with the cylinder pressure data in the inspection report for a comprehensive judgment. Looking only at the instrument panel is not reliable.
Q: How much spare parts budget should generally be reserved when purchasing used construction machinery?
A: It is recommended to reserve 5%–8% of the equipment transaction price, prioritizing hydraulic seals, filters, belts, and vulnerable engine parts. For export orders, this can be appropriately increased to 10%.
Q: What should be noted for logistics and customs clearance when exporting used bulldozers to Africa?
A: Confirm the age requirements of the destination country, clean the equipment to remove soil, and prepare complete accompanying documents including invoice, packing list, and certificate of origin. Breakbulk vessels to West Africa generally take 30–35 days, and a customs clearance agent should be arranged in advance.
Q: For a used loader purchased through the platform, when is the safest time to pay the balance?
A: The safest is to pay the balance before container loading or against a copy of the bill of lading. Do not pay the full amount in advance. For domestic transactions, settle on the spot after satisfactory inspection, and keep the transfer receipt and contract.
Q: Is the after-sales support for mining trucks the same as for used excavators?
A: The basic framework is the same, but mining trucks have more structural components and wear faster, so arrival inspection should be more detailed. It is recommended to additionally purchase a 3-month extended warranty for structural components, at a cost of about 2%–3% of the vehicle price.
