What Issues Should Be Noted When Purchasing A Second-hand Rotary Drilling Rig

When purchasing a second-hand rotary drilling rig, it is necessary to carefully identify the condition of the equipment to avoid increasing the subsequent usage cost due to hidden problems. The following are the key points that need to be focused on when making a purchase:

1. Equipment source and procedures: Prioritize choosing legitimate channels, verify the purchase invoice, certificate of conformity, property rights certificate and other documents, and confirm that there are no creditor disputes or legal flaws.

2. Core component inspection: Check the engine's operating conditions (such as power output and exhaust color), hydraulic system (whether there is oil leakage and whether the pressure is stable), and the wear degree of the main winch and slewing mechanism to determine the core performance.

3. Construction history and mileage: Through the number of working hours, construction logs or GPS data, understand the actual usage intensity of the equipment and avoid purchasing "faulty" machines that have been operating under long-term overload.

4. Appearance and structural damage: Observe whether there are cracks, deformations or repair marks at the welding points of the vehicle body, the tracks of the chassis, the drill pipes and drill bits, etc. Be vigilant against accident vehicles or refurbished machines.

5. Test drive and Troubleshooting: Conduct on-site test drives to check the smoothness of actions such as turning, drilling, and lifting. Pay attention to abnormal noises or lag. Ask the seller to demonstrate the fault repair records.

6. After-sales and spare parts support: Confirm whether the seller can provide a certain period of warranty service and whether the supply channels of equipment spare parts are unobstructed to avoid being in a passive situation during later maintenance.

Conclusion: When purchasing second-hand rotary drilling RIGS, a comprehensive assessment should be made from multiple dimensions such as compliance with procedures, core performance, usage history, physical condition, practical operation tests, and after-sales support. If necessary, professional institutions can be entrusted for inspection to reduce transaction risks and ensure the cost-effectiveness and reliability of the equipment.
