The telescopic mast can extend to handle 6m casing pipes in ODEX dilling,and retract to increase stability in conventional dillig. It saves the slidingrail, and features compact transport dimension, light weight and less trans-port cost, etc.
The concentrated control panel includes various controls, which are easy,stable and fficient, like the fast lift and feed can reduce auxillary time and im-prove working fficiency, and the adjustable dilling pressure can well adapt to diferent hole depths.
The strong rotating torque, with an output of 9000Nm, can deal with uncon-solidated rock formation very well and improve dilling eficiency.
The long-stroke leveling legs enhance the working stability of the drill rig, andenable it to be transferred with no need of crane.
The 132Kw engine drives the large-displacement plunger pump, excels in highpower and stable performance.
