1.ZEGA D450A is perfect in terms of mobility and reliability, higher productivity, stronger adaptability, and better drilling quality.
One drilling rig is for production drilling, by merging bench and pre-splitting drilling to speed up the stripping speed, and control the dilution rate. With lighter overall weight and compact sizes, D450A is very convenient to transfer between work sites and benches. Due to its excellent maneuverability and strong working ability, D440A drilling rig is widely adapted to various drilling applications, such as production blast holes in quarries and open-pit mines, pre-split holes, shock-absorbing holes, slope relief holes and deep hole drilling .
2.The working air pressure of the D450A drilling rig at 20 bars with the length of pipe of 4m; and two diameters of drill pipes to choose from; also for bottom holes, and the drilling speed significantly faster than other products of the same type.
