[Software scope and specialized qualities]
With rated torque of 4000 N·m, ZDY4000L(A) explosion-evidence crawler underground drilling rig is capable to drill 350m extended length boreholes in underground tunnel or mine roadways. The azimuth angle and pitch angle of the drilling rig can be adjusted at a assortment of -90°~90°, which can improve the adaptability and drill boreholes in a wide selection of angle. Relative compact dimension (the width in transportation approach is just .95m) permits the drill device to be operated and transported in narrow underground roadway. The rig has potential to drill as deep as 400m. Fantastic overall performance has been achieved after broadly employed for fuel drainage, water detect and discharge, geological exploration and engineering borehole drilling.
