Product Description
Rotary Drilling Rig SR275-S
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.
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%.
Economy: adopt power optimized control technology, adjust power distribution in real time, smooth compound action and fast speed; high utilization and low consumption.
Step winch: single layer wire rope winding on main winch drum, no extrusion wear between the ropes, and increase service life by 35%.
High reliability: adopt anti-vibration technology in rock drilling construction, fatigue resistance and long service life. Motor and reducer with high configuration and large reserve factor can meet severe working conditions.
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.
Convenient maintenance: the driving key of rotary drive set on the upper side, facilitates maintenance and replacement; connect a hose to drain port on rotary drive reducer for easy maintenance; double flaps provide large maintenance space.
Safety: 360° full-view monitoring, sound and light warning function.
