SR275-S 275kN.m Medium Rotary Drilling Rig 73M Depth for Soil and Rock
SR275-S is widely used in medium-sized construction of housing, bridge, municipal projects and stadium. It has great ability on drilling soil, pebble, rock and other mixed layers.
Advantages and highlights:
1. High efficiency
The best-selling model in medium-sized rotary drilling rigs. Equipped with the 6th generation Kelly bar with integral locking device, upgraded material and reinforced ring, the drilling efficiency increased by 10%.
2. Economy
Adopt power optimized control technology, adjust power distribution in real time, smooth compound action and fast speed; high utilization and low consumption.
3. Step winch
Single layer wire rope winding on main winch drum, no extrusion wear between the ropes, and increase service life by 35%.
4. High reliability
Adopt anti-vibration technology in rock drilling constr- -uction, fatigue resistance and long service life. Motor and reducer with high configuration and large reserve factor can meet severe working conditions.
5. Intelligent control
HD touch screen, 3s refresh rate, smooth screen. EVI mobile APP can realize remote monitoring in real time, one-click order and group management.
6. Convenient maintenance
