Underground Scaler, HT60
The HT60 underground scaler is a high-performance wheeled machine designed for scaling operations in tunnels, drifts, and underground chambers across metal mines and various subsurface engineering projects.
This scaler features a foldable working arm with a hydraulic hammer equipped with a rotary cylinder and dual extendable arms, enabling full-range coverage of the face, roof, sidewalls, and floor. Its load-sensing hydraulic system ensures energy efficiency, smooth operation, and accurate positioning.
Built with a compact structure and strong mobility, this underground scaler boasts a tight turning radius and powerful climbing ability, making it an ideal choice for improving both the efficiency and safety of underground scaling tasks.
Take control of your underground scaling with a solution that delivers complete surface coverage, intelligent control, and reliable performance where space and safety are critical.
