1. Power System: Utilizes a diesel engine (with an optional electric motor) coupled with a hydraulic pump unit. This configuration is adaptable to both non-electrified and electrified work environments, offering high mobility and stable power output. 2. Fully Hydraulic Drive: Hydraulic motors power the four primary functions—rotation, feed, lifting, and tramming—ensuring smooth operation and high torque output. 3. Angle Positioning: Hydraulic cylinders are used to position the drill mast, allowing for flexible and precise adjustment of the drilling angle. 4. Crawler Undercarriage: Equipped with a crawler-type chassis, the unit features excellent off-road capability, making it well-suited for navigating complex terrain at sites such as hydropower projects and mines.
