CCTEG2. Technical Features

Frameproof laptop, Directional Drilling Management System(DDMS)

Stingers That EnableOperation In 2–5m Seams

Tracked tram up to 2km/h for easy and independent rig moves and setup

Rotary torque up to 6000 Nm

CCTEG2. Technical Features

Dual cylinder feed frame for high push/pull and fast feed

Feed-frame tilt angle can be adjusted flexibly between -30 degree to +30 degree

CCTEG2. Technical Features

BLY260/9 mud pump crawler is a hydraulic pump crawler with large flow rate (the max flow rate is 260l/min) and high mud pressure (rated pressure is 9Mpa). The pump can maintain enough flow rate under high pressure work situation. It can supply enough hydraulic fluid power for downhole motor operation and drill cut remove to meet the requirement of long depth directional borehole drilling.
