In order to meet the market demand, Hong Yuan, one of the professional hydraulic drifter manufacturers, developed the new HYG650 hydraulic drilling machine – a high-performance Rock drilling Machine for blasting and hydraulic drifter drill – based on HYG550. It mainly focuses on the small vein and lower-roof tunnel in China. On the basis of keeping the equivalent impact power with HYG550, the weight of the entire machine is reduced by nearly 30% and the length is reduced by 15%. It is currently the lightest and shortest in length among the same class hydraulic drifter drills and Rock drilling Machines for blasting in the world.
