    Introduce:

    Rotary drilling rig XR260D

    Adopting specifically made hydraulic track(H-shped frame) and long diameter slewing bearing to insure high stability and transporting conveninence;Original packaging imported CUMMINS turbo charging engine provides strong drive power and meets Euro III emission standards; The hydraulic system uses limit power control and flow control to be high energy efficient; Single rope main winch to be an effective solution to the problem of wire rope wear, effectively improve the service life of wire rope; Detection device is installed on the main winch and the single layer rope makes depth detection more accurate; Machine designed to meet the requirements of CE directives, security and safer construction are guaranteed; A variety of configurations (such as: leg cylinders, casing drivers, etc.) are designed according to user requirements to insure high scalability; New structure of power head, the use of multi-stage shock absorption technology, the double seal structure improve reliability, removable drive plate ensures easy maintenance; Standard centralized lubrication systems makes maintenance more convenient.
