Original 285kN.m SR285R-MIII Rotary Drilling Rig with 2200mm Pile Diameter 94/61m Depth
SR285R is a medium-sized multi-functional drilling rig. It can be switched to other construction modes such as low headroom mode, casing mode, and CFA mode. The low headroom mode can be flexibly combined to achieve different heights and meet the working conditions under the bridge, the high voltage line and in the plant.
Advantages and highlights:
1. Convenient Switching
Multi-functional mast, universal interface, easy to switch among different modes, saving cost.
2. High Efficiency and Energy Saving
High torque and high crowd force ensure hard layer construction capacity; abundant power, real-time distribution, quick response and more energy saving.
3. Step Drum
Only single layer wire rope winding on main winch drum for interlocking bar, no extrusion wear between the ropes, long service life, low cost.
4. High Reliability
Working devices are designed under high standard, and go through strict system test with good durability. Multi-functional devices and base machine are designed for accurate and secure connection.
5. Intelligent Control
The locking device visualization technology shows the locking and unlocking process, to reduce Kelly bar wear and accidents. EVI mobile phone exclusive APP, remote monitoring equipment location, efficiency, fuel consumption, etc., one-key service call more convenient.
6. Convenient maintenance
Automatic central lubrication system saves time and effort. The full-length platform and upper carriage guardrail are optional, to provide full protection.
