What Kind of Second-hand Rotary Drilling RIGS Can Be Bought

Want to buy a second-hand rotary drilling rig to save costs, but worried about getting a "faulty machine"? Don't panic! Mastering these key points can help you avoid minefields and pick out equipment with high cost performance.

1. Check the source of the equipment: Prioritize choosing a legitimate second-hand equipment trading platform or a qualified dealer. Request to review the original purchase contract, maintenance records, and usage registration files of the equipment to ensure the source is clear and free of disputes.

2. Check the usage duration: Judge the degree of wear by the working hours of the equipment and the running time of the engine. Generally speaking, those with a cumulative working time of 5,000 to 8,000 hours and proper maintenance offer a relatively high cost performance.

3. Inspect core components: Focus on checking whether the engine power is sufficient, whether there is any oil leakage in the hydraulic system, and whether the drill pipes are deformed. The equipment can be started for a trial run to listen for the smooth operation sound and determine if there are any abnormalities.

4. Inspection and maintenance history: Thoroughly understand the number of major overhauls of the equipment and the reasons for them. If key components are frequently replaced, there may be structural issues. Minor daily maintenance is normal, while the repair of major faults requires careful assessment.

5. Verification of certificates and procedures: Confirm that all certificates such as the equipment qualification certificate, property rights certificate, and environmental protection inspection report are complete to ensure that the transfer procedures are legal and compliant, and avoid the inability to use the equipment normally due to incomplete procedures in the future.

6. On after-sales guarantee: Even for second-hand equipment, try to strive for a certain period of warranty or maintenance services. Clarify the warranty scope, repair response time and other terms with the seller to reduce the risks of subsequent use.

When purchasing a second-hand rotary drilling rig, one should not only pay attention to the price but also attach great importance to the quality of the equipment and after-sales service guarantee. By examining the "health status" of the equipment from multiple dimensions, carefully checking the procedures, and rationally negotiating the transaction, reliable equipment that not only meets the construction requirements but is also cost-effective can be selected.
