During the rainy season, there is a lot of rain and high humidity. Due to the long service life of second-hand rotary drilling RIGS, the sealing performance of their components may decline. If they are not properly protected and maintained, problems such as short circuits and component rust may occu Read More

In soft soil operations, second-hand rotary drilling RIGS often encounter problems such as easy hole collapse, unstable drilling resistance, and difficulty in controlling hole quality. Reasonable upgrading or replacement of key components can effectively break through these bottlenecks and significa Read More

Second-hand drill pipes, as the core power transmission components of rotary drilling RIGS, have certain wear and tear due to their early use. Daily maintenance should focus on preventing deformation and wear. This not only reduces construction failures but also extends the service life of the drill Read More

The electrical components of rotary drilling RIGS, especially sensors, are the "nerve endings" for the precise operation of the equipment. The condition of such components in second-hand equipment is complex, and a detailed inspection is required during machine inspection to avoid future malfunction Read More

The guide sleeve is a key component of the rotary drilling rig's drill pipe system. Although it may seem insignificant, it has a significant impact on construction accuracy and equipment lifespan. For second-hand equipment, accurately judging the condition of the guide sleeve is an important step to Read More
