1. High torque: The rig is equipped with a powerful power system to provide a large torque output. This allows the rig to operate in a variety of geological conditions, including hard rock and soft soil.
2. Large diameter: The drilling rig has a large drilling diameter capability and can carry out large diameter drilling operations. This is particularly important in underground engineering, such as the construction of subway tunnels, underground pipelines, etc., need to drill large diameter holes.
3. Full rotation: The rig has full rotation function, which can rotate 360 degrees in a small working space. This allows the rig to flexibly adapt to different construction environments and improve construction efficiency.
