Technical features of AT-2000L raise boring drilling machine
The drilling rig adopts dual-motor, fully hydraulic drive technology. It has the characteristics of large torque, stepless drilling speed, compact structure, simple and convenient installation, good impact resistance, and reliable operation. Compared with other ordinary rock drilling methods, the raise drilling rig has high production efficiency, good well quality, and safe operation. The drilling deflection is small.
Adopting double oil cylinders for propulsion, the drilling is stable and the well efficiency is high.
Its newly designed manipulator has reasonable design and stable and reliable movement, which greatly reduces the labor intensity of workers. Diesel engine driven, crawler track self-propelled.
The newly designed hydraulic system uses advanced hydraulic components at home and abroad to simplify the hydraulic pipeline structure. The overflow-free design reduces system heat and improves the stability of the hydraulic system.
Application of AT-2000L raise boring drilling rig
It is mainly used in rock formations of underground mines and other projects to drill 280mm pilot holes in the forward direction and expand 2000mm ventilation shafts, filling wells or pipe wells in the reverse direction. It can also be used as an underground excavation for large-section sky shafts and slide shafts in mines. The drilling depth is 300 meters, and the drilling inclination angle is 60°~90°
Application scope of AT-2000L raise boring drilling rig
The altitude of the place of use does not exceed 3,000 meters. When operating in a plateau environment with an altitude exceeding 3,000 meters, appropriate handling measures should be taken.
The ambient temperature is -10℃~+40℃, and the maximum relative humidity is below 90% (when the temperature is 25℃). When exceeding the above range, appropriate measures must be taken.
The power supply voltage limit deviation is ±5%; the AC frequency limit deviation is ±1%.
