AT-2000L frame integral type shaft drilling rig is a heavy-duty shaft construction equipment designed for your large-diameter, deep-hole and high-stability needs. This equipment adopts an integrated rigid frame structure, abandons wheel-rail or articulated mobile design, and sacrifices some flexibility in exchange for stronger drilling stability and construction accuracy. It is suitable for fixed-station, ultra-hard rock formations or ultra-large-diameter mines and hydropower projects.
The AT-2000L frame-integrated raise drilling rig has no moving parts and an overall welded/bolted structure, which improves vibration resistance by 50% and reduces the risk of deflection when drilling deep holes. In addition, it is fixed to the concrete base through hydraulic anchors and can resist more than 2000 kN of counter-torque.
Our AT-2000L raise boring machine adopts high torque and high thrust design, which significantly improves the drilling speed under hard rock conditions and can effectively shorten your construction period. In addition, the use of automatic rod changing technology reduces manual intervention and has strong continuous operation capability, which can greatly save your construction costs.
Equipped with a high-pressure mud circulation system to ensure efficient discharge of deep hole debris. In addition, due to the integrated design, it has stronger stability and can drill into a 400m deep hole.
The frame is made of low-alloy high-strength steel (such as Q690D), and the welding area is stress-relieved;
Yes, but it needs to be combined with advanced grouting reinforcement or casing drilling (synchronous lowering of the wall protection pipe)
