How To View The Market Price of Second-hand Rotary Drilling Rig Parts? Tips To Avoid Buying Expensive Items

The prices of second-hand rotary drilling rig parts vary greatly due to differences in condition and brand, covering everything from filter elements worth tens of yuan to hydraulic pumps worth tens of thousands of yuan. Mastering the logic of market price judgment and techniques to avoid pitfalls can effectively reduce procurement costs and prevent resource waste.

1. Pricing for core anchor parameters: Core components such as hydraulic cylinders and drill pipes are priced based on cylinder diameter, stroke or wear degree. For instance, a complete main cylinder with a diameter of 160mm is approximately 2,700 to 3,500 yuan per piece. If the wear exceeds 0.3mm, the price will be discounted by more than half. For non-core components, the pricing range of 20% to 50% of similar new products can be referred to.

2. Distinguish brand value gradients: The price of intact parts for imported brands such as Rexroth and Parker can reach 20% to 30% of new parts, while parts for small brands or discontinued models may only be worth the residual value of disassembled parts, with very little room for premium.

3. Be vigilant against the trap of fake quality: If the surface of the accessories is covered with new paint, pay special attention to checking the oil leakage marks of hydraulic components and the wear marks of metal parts. New paint is often used to cover up aging or damage problems. Hydraulic components that have been in use for more than 8,000 hours should be purchased with caution.

4. Compare the price differences in regional markets: The quotations in the Yangtze River Delta and Pearl River Delta are 15% to 20% higher than those in the central and western regions, but the supporting maintenance services are more complete. In regions with strict environmental protection policies, the price will be reduced by 5% to 8% without a certificate of residual oil treatment.

5. Make good use of the platform's price benchmark: Check the average price of the same model through 1688 or professional parts websites. For example, the market price of Sany SR200 guide wheels is about 1,000 yuan. If it deviates from this range by more than 30%, be cautious. Give priority to suppliers that offer membership prices or bulk discounts.

6. Verify traceability and compliance: Maintenance records and original factory serial numbers are required. Modified parts without documentation may pose safety hazards and have a low residual value. Imported accessories need to confirm the customs declaration procedures to avoid compliance risks.

In conclusion, when determining the price of second-hand rotary drilling rig parts, it is necessary to take into account parameters, brands and regional factors. Through multi-platform price comparison, professional testing and traceability verification, not only can the market price be accurately controlled, but also hidden risks can be avoided, achieving the maximization of cost performance.
