■ Application Scope
With rated torque of 4000 N·m, ZDY4000L(A) explosion-proof crawler underground drilling rig is capable to drill 350m long distance boreholes in underground tunnel or mine roadways. Both azimuth angle and pitch angle can be adjusted at a range of -90°～90° which can enhance the adaptability and drill boreholes in a wide range of angle. Relative compact dimension (the width in transportation process is just 0.95m) allows the drill machine to be operated and transported in narrow underground roadway.
The rig has capacity to drill as deep as 400m. Outstanding performance has been achieved after widely used for gas drainage, water detect and discharge, geological exploration and engineering borehole drilling.
