Upward Cutting Groove Type Raise Boring Machine

High turnaround speed: Equipped with a bridge-drive wheeled chassis and a cab, this design enhances the vehicle’s travel speed during turnaround operations, meeting the demands of frequent turnarounds required for groove-cutting construction.

Simplified design: Adopting a two-propulsion-cylinder, three-support design, this configuration ensures stable equipment operation while facilitating the easy installation and removal of large-diameter cutterheads. The integrated slag collection hopper and stabilizing rod mechanism design effectively reduces the overall operating height of the main unit, minimizes excavation volume in the working chamber, and helps cut down on construction costs.
