Second-hand rotary drilling RIGS, having been in use for a period of time, require more attention to the wear and tear of their vulnerable parts. Reasonably grasping the replacement cycle of vulnerable parts can not only ensure construction safety but also improve construction efficiency and avoid p Read More

When second-hand rotary drilling RIGS are stored for a long time, due to their prolonged idleness, moisture intrusion and metal rust are the main risks. If they are not properly maintained, it can lead to component damage and performance degradation. Proper moisture-proof and rust-proof treatment is Read More

The hydraulic system is the "power heart" of a second-hand rotary drilling rig, and its performance directly affects the drilling efficiency and operation safety of the equipment. The hydraulic system of second-hand equipment is prone to malfunction due to wear and tear from previous use and aging o Read More

In the construction of rotary drilling RIGS, the mud pump, as the core component for transporting mud, its performance directly affects the drilling efficiency and construction safety. Second-hand mud pumps have become the choice of some users due to their cost-performance advantage. However, to dis Read More

The drill bucket of a rotary drilling rig is a key component for construction efficiency, and its selection directly depends on geological conditions. Choosing the right second-hand drill bucket can not only reduce costs but also avoid problems such as stuck drill and low efficiency. The following s Read More
