Supply And Demand Situation of Second-hand Rotary Drilling Rig Parts: Which Parts Are Prone To Shortage?

The stable operation of second-hand rotary drilling RIGS relies on the support of accessories, but some accessories are often out of stock due to factors such as usage characteristics and supply constraints. Understanding the types of parts that are prone to shortage can help equipment owners stock up in advance and avoid delays in construction progress due to part shortages.

1. Drill pipe joint: As the core component of drill pipe connection, it is subject to torque and impact force for a long time, with a fast wear rate and high replacement frequency. Moreover, the specifications of connectors for different models vary greatly, and the customization cycle is long, which often leads to the shortage of compatible models.

2. Hydraulic seals: Key protective components of the hydraulic system, they are prone to aging due to high temperatures and oil stains and need to be replaced regularly. Its model classification is complex and diverse. For some imported models, the sealing parts rely on the original factory supply, resulting in large inventory fluctuations and a high risk of stockouts.

3. Main hoisting wire rope: It is responsible for the lifting operation of the drilling rig, with concentrated force and easy wear, and is a high-frequency consumable component. The production cycle of high-quality steel wire ropes is relatively long. If there is a sudden large-scale procurement demand, a supply gap is likely to occur in the short term.

4. Power system sensors: They are used to monitor the operation data of engines and hydraulic pumps, with high precision requirements and are prone to damage from environmental interference. Some old model sensors have been discontinued, and the circulation in the second-hand market is low, making it difficult to find suitable accessories.

5. Chassis track plates: They are prone to bumps and corrosion during construction in complex sites and require frequent replacement. The track plates need to match the chassis model. The inventory of track plates for niche or imported models is scarce, and the replenishment cycle often exceeds 15 days.

6. Slewing bearing: A core component connecting the machine body and the slewing mechanism, it has a relatively long service life but requires urgent maintenance once damaged. Its production process is complex, the delivery period is long, and the maintenance of second-hand equipment is mostly due to sudden demands, which makes it prone to shortage problems.

In conclusion, the parts that are prone to shortage in second-hand rotary drilling RIGS are mostly high-frequency consumable parts or parts with high compatibility requirements. Their supply is affected by factors such as production cycles, model specifications, and inventory management. It is recommended that equipment owners, in combination with the replacement cycle of spare parts and their own construction plans, reserve core spare parts that are prone to shortage in advance, and at the same time establish a stable channel of spare parts suppliers to reduce the risk of shortage.
