When Purchasing A Second-hand Rotary Drilling Rig, How Can One Avoid Getting A Refurbished One

In the field of construction, second-hand rotary drilling RIGS have become the choice of many enterprises due to their high cost performance. However, the market is flooded with refurbished machines. Once you fall into a trap, the maintenance cost will be high and it will affect the construction progress. Mastering the following 6 key points to avoid pitfalls will help you accurately identify and purchase your device with confidence.

1. Verify the factory information of the equipment: Check the nameplate and certificate of conformity of the equipment, verify whether the factory number is consistent with the manufacturer's database, check for any signs of tampering, and confirm the true "identity" of the equipment.

2. Observe the appearance details: Carefully check if the welds are uniform and natural, if there are any color differences or flow marks on the paint surface, and if there are any signs of screwing on the screws. Refurbished machines often reveal their flaws in these details.

3. Inspect core components: Start the equipment, listen to whether the engine runs smoothly, check for any oil leakage in the hydraulic system, and test whether the performance of key components such as the power head and drill pipe meets the standards.

4. Check the usage records: Ask the seller to provide the maintenance and repair records of the equipment and the working hours. By analyzing the data, determine the actual usage status of the equipment and be vigilant against abnormal data modifications.

5. Seek professional appraisal: Invite experienced mechanics or third-party testing institutions to conduct a comprehensive inspection of the equipment using professional tools and obtain an objective assessment report.

6. Confirm the transaction channel: Choose a legitimate second-hand equipment trading platform or a reputable merchant, sign a detailed contract, clarify the after-sales terms, and protect your own rights and interests.

Conclusion: When purchasing second-hand rotary drilling RIGS, maintaining a cautious attitude and carefully screening from multiple dimensions can effectively avoid the risks of refurbished machines, purchase reliable and cost-effective equipment, and lay a solid foundation for engineering construction.
