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

In the construction of long piles, the selection of the length of the drill pipe of the second-hand rotary drilling rig directly affects the construction efficiency and the quality of the pile. Choosing a short length may result in the failure to reach the designed pile depth, while choosing a long Read More

The electrical system of a second-hand rotary drilling rig is the "nerve center" of the equipment's operation, responsible for controlling power, operation and monitoring functions. Aging of the lines, loose joints or failure of protection can easily cause short circuits, signal interruptions and ot 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 cooling system of a second-hand rotary drilling rig is the key to ensuring the stable operation of the equipment. If impurities accumulate in the water tank and radiator, it can easily lead to a decrease in heat dissipation efficiency, engine overheating, and subsequently cause malfunctions. Mas Read More
