Technical Features of XR260D：
• XR260D adopts single layer main winch, which effectively reduces the wear of steel wire rope and extends its service life.
• The infrared camera is convenient for operators to observe the steel wire rope of main winch from inside the cab at any time.
• Multiple configurations can be customized according to the requirements, like outrigger cylinder, automatic slewing device, etc.
• It adopts imported electric controlled turbocharged Cummins engine, which meets Euro Ⅲ emission standard, featuring strong power, energy-saving and environmental care.
• The hydraulic system adopts power limit control and positive flow control, which makes the hydraulic system more efficient and more energy-saving.
• With the patented parallelogram luffing mechanism, the machine can cover wide work areas; The drill mast is designed as box structure made of high strength materials, which ensures the boring precision with higher rigidity and strength.
• It adopts new structure power head with multi-stage vibration absorption technology and dual seal structure, which effectively improved reliability; and the detachable pressing plate is convenient for repair.
• It adopts intelligent control system and the measuring device is more accurate and reliable.
• It can be equipped with optional 6 section drill stem, which can reach the max. drilling depth of 80 m.
