Small-scale construction sites often encounter problems such as narrow space, limited turning radius, and difficulties in equipment entry and exit. Conventional rotary drilling RIGS are difficult to adapt due to their large size and poor flexibility. The second-hand compact rotary drilling rig, with Read More

Rock strata have high hardness and dense structure. When second-hand rotary drilling RIGS are in operation, problems such as slow drilling, rapid wear and tear of accessories, and great difficulty in hole formation are prone to occur. With targeted special accessories, it can effectively cope with t Read More

Bridge construction has strict requirements for the accuracy, depth and stability of drilling. The drill pipe and drill bit of second-hand rotary drilling RIGS, as core working components, directly affect the quality of hole formation and construction safety. The following six key perspectives are p Read More

The classification of rotary drilling RIGS is diverse, usually based on different dimensions such as structure, function and power. Understanding its classification can help us better select appropriate equipment based on engineering requirements and improve construction efficiency.1.By power type: Read More
