Key Features
- 1,000 m NQ and 650 m HQ capacity in one mast: deep enough for most hard-rock exploration programmes without a second rig.
- Hydraulic head with 0 – 1,200 rpm stepless control and 4,100 N·m torque, matched to both impregnated and surface-set bits.
- 1,200 m wireline winch with 140 m/min line speed keeps rod trips short on deep holes.
- 0 – 90° mast with 3.5 m feed stroke, power-head side-shift and 133 mm foot clamp for HQ and PQ tooling.
- Track-mounted crawler undercarriage at 3.5 km/h with manual + wireless-remote walking and hydraulic levelling jacks: moves between drill pads and is operated from a safe distance.
- Weichai six-cylinder 129 kW diesel with 24 V electrics, air compressor and water pump on the same skid.
Typical Applications
CH-1200 specifications, answered
How deep can the CH-1200 drill?
BTW/BQ 1,400 / 1,200 m · NTW/NQ 1,200 / 1,000 m · HTW/HQ 900 / 650 m · PQ 400 m. Depth capacity falls as the rod size grows, so plan against the figure for the tooling you intend to run.
What hole and rod sizes does the CH-1200 take?
60 – 122.6 mm hole (BTW/BQ – PQ).
What powers the CH-1200?
Weichai 6-cylinder, 129 kW @ 2,300 rpm.
How large is the CH-1200 and what does it weigh?
weight 7.6 t.
