XR240E

XXCMG XR240E rotary drilling rig performance characteristics: 1.As a multi-functional machine, XR240E can realize the quick switching of functions such as crowd cylinder, crowd winch to meet more different construction needs; 2.It adopts Isuzu electronically controlled turbocharged engine with lower fuel consumption and convenient service; 3. The rotary drive and main winch performance is increased by 20%, so the work efficiency is much higher; 4. The main and auxiliary winches both adopt the single-row rope technology, the service life of wire rope is 2 ~ 4 times longer than that of multi-layer rope, which makes the cost lower; 5. The double jib parallelogram luffing mechanism has a large support angle and a 16% increase in support range,which makes the operations more stable; 6. The hydraulic system adopts negative flow control technology which has a fast response and good handling performance; 7. High-power temperature-controlled independent hydraulic oil cooler can meet the construction requirements of high- temperature areas and adjust the fan speed accorading to temperature changes to achieve energy saving; 8. The intelligent control system can achieve functions such as automatic adjustment and display of mast perpendicularity, automatic slew, automatic spin-off, automatic lifting and concrete pouring and pile type display, etc, The bus panel design is adopted to prevent misoperation; 9. The chassis can be equipped with transport legs (optional) and remote control operation to achieve easier and safe site transfer and transportation.
