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

In municipal engineering construction, second-hand rotary drilling RIGS have become the choice of many construction parties due to their high cost performance. However, choosing the right equipment and assembling the right accessories are the keys to ensuring construction efficiency and safety. Belo 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

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
