XR series of rotary drilling rig
Technical Features:
•Special chassis for drilling rig that adopts advanced design methods have extra stability. The chassis structure has high intensity, it takes heavy telescopic hydraulic crawler, convenient for transportation, and have superior travel performance.
•The high performance main hydraulic winch and auxiliary winch is installed in the slewing table of the drilling rig, making the operation flexible and convenient. The main winch has controllable free drop function, this ensures the synchrony of thrusting speed of drilling head and the winch speed.
•The PLC controller can make automatic and manual control of the mast rake, automatically measure the pressure of the key parts and alarm, make real time measurement of the boring depth, dynamic and numeric display, the drill mast automatic or manual control, color LCD.
•The patented rectangle articulated system makes the work area more wide. The mast adopts high strength box type, it has high rigidity and intensity, which effectively guarantees the precision of boring. The articulated parts all adopt lubrication-free bearings, ensuring flexible rotary.
