Mine Hydraulic Anchor Bolt Drilling Machine
The PVT UDS391 can install both split-set and resin-grouted bolts ranging from 1.5 to 2.4 meters (5 to 8 feet) in length. It features a high-power diesel engine, heavy-duty four-wheel drive, articulated steering, and an FOPS-certified safety canopy (Falling Object Protective Structure). The machine's overall layout ensures excellent stability when traveling in narrow roadways and engineering tunnels. The rig is easy to operate and highly serviceable, with all routine maintenance tasks accessible from ground level.
The PVT UDS391 is a compact and flexible single-boom electro-hydraulic bolting rig, designed for roadway support in underground mines, rock reinforcement in tunneling projects, and bolt installation in hard and fractured ground conditions. It is equipped with an 11 kW Sandvik LD30 hydraulic rock drill, delivering a maximum torque of 420 Nm, offering exceptional performance in hard and broken rock.
