Underground Mining Equipment
Underground Scaler, HT65
The HT65 underground scaler is a specialized machine designed for scaling and hazard removal in mining and tunneling operations. Ideal for metal and non-ferrous mines, hydropower projects, railways, highways, and culverts, it offers reliable performance in complex underground environments.
With a total height of just 2.1 m and a cab that can be lowered to 1.7 m, our underground scaler is engineered for superior clearance and maneuverability. Its narrow 1.6 m width allows it to easily navigate tight, 3-meter-wide right-angle tunnels commonly found in mining sites. Featuring excellent lateral and longitudinal stability, this underground scaler delivers outstanding passability and efficiency in confined workspaces.
Navigate complex underground spaces with confidence using a solution that enhances clearance, improves operator safety, and keeps your operation moving through the tightest corners.
- High Reach and Strong Mobility: offers a scaling height of up to 6.5 m and features an articulated chassis with balanced shifting, tight turning radius, and strong climbing capability
- Operator Safety and Visibility: equipped with an ergonomically designed FOPS certified cab and HVAC system, offering superior protection, wide visibility, and comfort; a rock guard shields the operator, and manually adjustable roof lights enhance underground visibility
- Emergency Safety System: specially designed safety features activate multiple mechanisms simultaneously in hazardous situations including lifting push rods and outriggers, retracting the hydraulic hammer, and initiating reverse motion to ensure rapid evacuation and protection of both personnel and equipment
