What Are The Differences between Second-hand Rotary Drilling RIGS And New Ones? Explain Everything From Structure To Performance in One Go

As the "underground vanguard" in engineering construction, the performance of rotary drilling RIGS directly affects the construction efficiency and cost. Many people are torn between second-hand equipment and new ones when making a purchase. The difference between the two is far more than just the price. The following breaks down the core differences from six dimensions:

1. Structural materials: The structural components of the new machine are made of brand-new high-strength steel, and the welding process complies with the latest standards. There are no wear marks on key parts. Due to long-term stress, second-hand equipment may experience fatigue deformation of structural components, and hidden cracks are prone to occur at the welds.

2. Core components: The hydraulic system, engine and other core components of the new machine are all brand new original factory parts, with the best matching degree and sealing performance. The core components of second-hand equipment may have been repaired or replaced, and their performance parameters may deviate from the original design, resulting in a higher failure rate.

3. Performance: The new machine is in the best state in terms of drilling speed, hole-forming accuracy and power output stability, and can adapt to complex geological conditions. Second-hand equipment, due to the aging of its components, may experience power attenuation, increased fuel consumption, and is prone to "breaking down" under extreme working conditions.

4. Operating cost: The initial purchase cost of a new machine is high, but the maintenance and repair costs for the first 3 to 5 years are low, and the loss from downtime due to faults is small. Although second-hand equipment has a low purchase price, it requires frequent replacement of vulnerable parts in the later stage, and the hidden maintenance cost may increase year by year.

5. After-sales Guarantee: New machines enjoy the complete warranty service provided by the manufacturer, including free repair, technical support and spare parts supply. Second-hand equipment usually lacks the original factory warranty. Maintenance relies on third parties, and it is difficult to guarantee the compatibility of parts and the response speed of services.

6. Residual value rate: The depreciation rate of new machines is relatively fast in the first two years, and then it tends to stabilize. When resold again, the retention value rate is relatively controllable. The residual value of second-hand equipment is greatly affected by its original usage condition. Severely aged equipment may face the predicament of "not being able to fetch a good price".

Overall, the new machine is suitable for long-term and high-intensity construction projects, ensuring efficiency and stability. Second-hand equipment is more suitable for short-term emergencies or scenarios with limited budgets, but the condition of the equipment needs to be carefully evaluated. When making a purchase, it is necessary to take into account the project cycle, geological conditions and maintenance capabilities, and weigh the short-term costs against long-term benefits.
