Atlas Copco Surface drill rigs

AirROC T35, D45 and D50

Hole diameter AirROC T35, 64-102 mm (2 1/2’’- 4”)AirROC D45, 105-127 mm (4”- 5”)AirROC D50, 105-140 mm (4”- 5 1/2’’)

AirROC T35, the tophammer medium size air drill rig, with its unique VL 140 pneumatic rock drill is the pathfinder opening new horizons of drill efficiency.

AirROC D45 and AirROC D50 are down-the-hole drill rigs, that can work with ease on steep grades and the roughest of terrain. These machines are suitable for limestone, aggregate quarries and surface mining applications.

Rugged efficiencyConstruction work or fine quarry drill work, this rugged drill rig navigates steep climbs and rough terrain efficiently. The Atlas Copco air compressor ensures fast and efficient drilling, and keeps going on for longer hours of work. Servicing, when needed is a quick one-man task.

Effectiveness built inTramming is effected by features like independent 11 hp piston air motor per track and an enclosed gear drive. Forward or reverse movement, the spring applied disc brakes always remain effective. Hydraulically cushioned track oscillation absorbs the shock loads and the oscillation may be locked out when a solid setup for drilling is desirable. A simple trap door centralizer is accessed at the touch of a foot.

Unique rock drill and rotation unitsThe unique Atlas Copco VL 140 air rock drill with a new cycle and piston design has a positive effect on the drill efficiency. Down the hole tasks are covered by BRH rota-tion units or by the ARH rotation units depending on the drill hole size. The ARH unit works a planetary gearbox, driven by a high power air vane motor for bigger holes.

Easy control. Ample powerSide mounted tramming controls provide easy access. During compressor towing a safety lockout switch blocks reverse motion. Hole collaring is made operator conveni-ent by a fine feed regulator and prevents stuck steels. A piston type air feed motor drives a heavy roller chain, providing sufficient pullout power, and all the pull down ever need in drilling.

Pioneer strength and agility
