Due to the long service life of second-hand rotary drilling RIGS, the performance of some components may decline, and fuel consumption is more likely to increase, which will directly increase construction costs. Optimizing fuel consumption not only reduces fuel costs but also lessens the load on equ Read More

In the construction of rotary drilling RIGS, the drill bit is the core component. The drill bits of second-hand rotary drilling RIGS, due to their longer usage time, are more prone to wear and tear. If new drill bits are directly replaced, the cost will increase. However, reasonably repairing and re Read More

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 soft soil operations, second-hand rotary drilling RIGS often encounter problems such as easy hole collapse, unstable drilling resistance, and difficulty in controlling hole quality. Reasonable upgrading or replacement of key components can effectively break through these bottlenecks and significa Read More

The maintenance cost of second-hand rotary drilling RIGS directly affects the cost-effectiveness of equipment usage. The expense is influenced by the age of the equipment, usage frequency, and maintenance standards, mainly covering aspects such as consumable replacement, component inspection, and pr Read More
