WIRELINE CORE TO 500 METRES. COMPACT ENOUGH TO GO WHERE THE GEOLOGIST POINTS.
The JCD400 is a compact, fully hydraulic crawler core drilling rig for mineral exploration
and geological coring. It pulls wireline core in HTW, NTW and BTW sizes — 500 m on BTW,
400 m on NTW — with the inner tube coming up on the wire, not on the rods. Fewer trips,
more metres cored per shift.
Walks itself to the collar. Steel crawler tracks, 3.5 km/h travel and a
40° climbing ability put this rig on holes a truck can't reach. Dual manual and remote
control lets the operator walk it up a slope from a safe distance, then the one-piece
ground-touching mast sets any angle from 45° to vertical.
Hydraulic everything. A 70 kW YUCHAI turbocharged diesel drives a
20 MPa / 160 L/min hydraulic system — feed, rotation, lifting and clamping are all
hydraulically driven. The 1 900 mm feed stroke and 14-ton pull-up handle stuck rods
and hard ground without drama. Prefer Cummins power? The engine can be changed to a
Cummins diesel on request — just ask when you enquire.
Mud pump and hoist on board. The integrated BW-100 pump delivers up to
100 L/min at 7 MPa for clean cuttings removal, and the 600 kg rope hoist with 600 m of rope
handles the wireline work. At 4.3 tons and 4.2 m long it moves on a drop-side truck.
Delivered drill-ready by Drillbuilders. We supply the JCD400 with
commissioning support and back it from our Mokopane workshop. One supplier, one phone call.
