Rail-mounted (reverse) well drilling rig main features:

♦ Safe and reliable.The rail-mounted Raise borer Machine adopts fully mechanized operation and remote control, providing a good working environment and high safety.

♦ High work efficiency and good well quality.The rail-mounted Raise borer Machine uses roller cutters for rock breaking, resulting in smooth well walls, low deviation rates, and high drilling speeds.

♦ Easy to operate, low construction costs, and good economic efficiency.It uses advanced hydraulic transmission and control, is easy to operate, has low work intensity, and reduces labor costs.

♦ Simple installation.The main machine adopts a frame structure with upper and lower support positioning, has a large load-bearing capacity, is stable and firm, and can be constructed without prior foundation (for depths less than 100 meters), significantly reducing construction costs and time.

♦ High drill rod strength.The Raise borer Machine drill rod threads adopt the DI-22 international standard, with a large spiral lift angle and coarse tooth profile, effectively preventing issues like drill rod burning and breakage, ensuring higher reliability.

♦ Widely applicable.The Raise borer Machine can create hole diameters of Φ0.9 to 2.4m and depths of 280m, can be combined with freezing and drilling methods to form comprehensive drilling technology, and can also be applied in underground engineering construction fields such as hydropower, metallurgy, subways, transportation, civil defense, and military industry, with broad application prospects.
