Pioneer strength and agility
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 efficiency
Construction 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 in
Tramming 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.
Easy control. Ample power
Side mounted tramming controls provide easy access. During compressor towing a safety lockout switch blocks reverse motion. Hole collaring is made operator convenient 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.
Main benefits
•Application compatibility due to interchangeability DTH
•Transportation is made easier by fixed length boom and drill width
01.Powerful feed motor
