XR240E Rotary Drilling Rig

1. Multi-functional in one machine: enables rapid switching among cylinder pressure, winch pressure, casing oscillator, continuous flight auger, dual power head and other functions to meet more diverse construction needs;

2. Equipped with Isuzu electronically controlled turbocharged engine for lower fuel consumption and convenient, fast service;

3. Working performance of the power head and main winch improved by 20%, resulting in higher operating efficiency;

4. The power head can be equipped with a torque multiplier (optional), enabling casing drive torque up to 360 kN•m and stronger casing lowering capability;

5. Both main and auxiliary winches adopt single-layer spooling technology; wire rope service life is 2–4 times longer than that of multi-layer spooling, resulting in lower use cost;

6. Adopts dual-boom large parallelogram luffing mechanism, with large support angle and 16% increased support range for more stable operation;

7. The main hydraulic system adopts negative flow control technology for fast response and good control performance;

8. High-power temperature-controlled independent hydraulic oil cooler meets construction needs in high-temperature areas and can adjust fan speed according to temperature changes to achieve energy savings;

9. Intelligent control system realizes automatic adjustment and display of mast verticality, automatic slewing, automatic soil dumping, automatic lifting and grouting for continuous flight auger method, and pile type display, etc.; bus panel design effectively prevents misoperation;

10. The chassis can be equipped with transport outriggers (optional), remotely controlled, making transport and relocation simpler and safer.
