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

After obtaining a second-hand rotary drilling rig, initial maintenance is a crucial step to avoid hidden faults and extend the equipment's lifespan. Many second-hand devices have problems such as aging components and accumulation of impurities due to storage or idleness. Through scientific initial m 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

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
