Fully Hydraulic Core Drill Rig HW-YDX-400XL
A mid-sized rig in the series: 4.3 t machine weight, holes down to 500 m. The rotary head delivers 300 to 500 N·m, the feed a stroke of 1900 mm.
Drilling runs in HTW, NTW and BTW sizes, at angles between 45 and 90 degrees. The mast lifts 12 t and pushes down with 6 t. The hydraulic system works at 21 MPa and 168 L/min.
The turbocharged Yuchai engine is rated at 78/70 kW. The Bw-90 mud pump delivers 30 to 90 L/min at 4 to 7 MPa, and the winch holds 500 m of rope. The undercarriage climbs gradients up to 45 degrees.
