Atlas Copco Blasthole T4BH series Drills DTH and Rotary drilling Multi pass Holediameter 5 %in 97/8 in (143 251 mm) Maximum hole depth for 25 ft tower: 147 ft (45 m) Maximum hole depth for 30 ft tower: 177ft (54 m) L

Combining high mobility with power and productivity The T4BH is designed for multipass, high pressure, DTH drilling The rugged and reliable T4BH features a 25 ft (76 m) tower and can drill a 2216" (68 m) clean hole in a single pass, while multipass drilling can reach to a total depth of 14716" (45 m) through a 5 rod carousel TheAtIas copco T4BH is synonymous with mobility, power, performance, and productivity Mounted on a custom carrier, the T4BH is designed to perform in rough terrain and has been the leading blasthole drill in its class in the quarry and mining industries for over 35 years The T4BH is a truck mounted, hydraulic tophead drive, specifically designed for DTH high pressure blasthole drilling An optional 30 ft (91m) tower is also available with the 8 x 4 carrier option Tower and feed system Raising the tower with a full complement of up to five 25 ft (76 m) drill pipes in the carousel can be accomplished in less than one minute The tower is raised and lowered by two hydraulic cylinders Tower pinning, pipe changing and drilling are performed remotely from within the operator's cab The feed system is powered by two hydraulic feed cylinders that raise and lower the rotary head smoothly and positively by way of heavy duty feed chain for pulldown and pullback The highspeed feed functions increase drilling efficiency and give the operators faster drill feed rates Standard rotation'on the T4BH is supplied by a hydraulic rotary tophead The rotary head is mounted to the feed chains by way of a mounting plate and two pins on both sides of the head, allowing the head to "float" This helps to prevent thread wear or damage during joint make up Rotary or DTHdrilling The T4BH is designed to handle 4" (102 mm) to 7 (178 mm) drill pipes and can be used for DTHor rotary drilling of holes with diameters from 5 %" (143 mm) up to 9 ~ (251 mm) Three different high pressure compressors can be provided for the T4BH, ranging from 900 cfm up to 1,250 cfm The "onoff" regulation system of the high pressure compressor can remove load during nondrilling operations This extends compressor life, saves energy and provides an easier startup With a weight on bit force of up to 30,000 Ibf (133 kn),the reliable T4BH is well matched for rotary drilling as well Compressor range HighpressureDTH HighpressureDTH HighpressureDTH 900efm@350psi/254m3/min@24bar 1,070efm@35Opsi/303 m3/min@24bar 1250efm@35Opsi/354m3/min@24bar,,1 l '"'~ ' :';J'
