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

The low-temperature environment in winter has a significant impact on the performance and lifespan of second-hand rotary drilling RIGS. If not properly maintained, problems such as difficult startup and component freezing damage may occur. Proper anti-freezing and start-up protection not only reduce Read More

The drill bit is the "tooth" of the rotary drilling rig that directly contacts the stratum. Its type selection is closely related to the operation efficiency and the quality of hole formation. Understanding the types of drill bits and key points for second-hand selection can help you control costs w Read More

As the "underground pioneer" in engineering construction, the residual value rate of rotary drilling RIGS in second-hand transactions is the core concern of both buyers and sellers. The residual value rate not only reflects the remaining value of equipment but is also a key indicator for measuring i Read More

When purchasing second-hand rotary drilling RIGS in a different location, as it is impossible to conduct on-site and immediate inspections, remote preliminary screening becomes the key to avoiding risks. Judging the condition of equipment through scientific methods can reduce the blindness of subseq Read More
