The AT-2000W column-type wheel-rail type skylight drilling rig is a hybrid equipment designed for medium-depth skylight construction. It combines column-type rigid support with a wheel-rail mobile system to achieve a balance between flexibility and stability.
LOOKING AT-2000W column-wheel-rail skydrill uses hydraulic telescopic columns to provide vertical rigid support, anchored with the top plate/bottom plate during drilling to resist reverse torque; heavy-duty steel wheels + embedded tracks support rapid movement and precise positioning.
The wheel-rail chassis used by AT-2000W supports the rapid transfer of the drilling rig between workstations, which can save your operation time and cost; in addition, the column frame can provide rigid support and reduce the risk of drilling deviation.
Our AT-2000W 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.
The workstation spacing is ≤500 meters, and frequent transfer is required; the drilling depth is 200-350 meters, and the rock is medium-hard to hard rock; the tunnel slope is ≤15°, and the section height is ≥3.5 meters.
The top of the column is fixed to the bottom plate by hydraulic anchors, and the bottom wheel rail is hydraulically locked; a counterweight (adjustable) is added to the tail of the drilling rig to offset the lateral moment during inclined drilling.
