Second, the use and characteristics of the drilling rig:
1). Use:
Engineering anchoring drill can be used in urban construction, railway, highway, river, hydropower and other projects to drill rock anchor hole, anchor hole, blasting hole, grouting hole and other drilling construction.
2). Features:
1, the drill selects the motor through the high-performance reducer as the reverse power; Use cylinders for propulsion. The hydraulic system is eliminated, so the mechanical efficiency is high, the cost is low, and the performance is stable.2, with anti-card maintenance, when the drill is stuck, the motor is not easy to burn, the reducer is not easy to damage.
