Product Feature
◆The tooth rail to support the thrust/pullback motion of the drive carriage is made of highly wear-resistant alloy steel, having the features of pleasant reliability, high transmission efficiency and long endurance.
◆Cab with air-conditioner (cooling & warming) as a standard. Control panel considered with man-machine engineering provides easy and satisfy operation.
◆CUMMINS high-power engine provides abundant power storage to make the rig suitable for a wide range of work conditions.
◆Double-speed operation of rotation & thrust/pullback provided by optimum hydraulic design, which enhances the adaptivity of different work conditions and is convenient to load/unload drill rods.
◆American PERMCO high pressure master hydraulic pump, providing high torque and efficiency. Speed reducer of imported brands as a standard features stable performance & reliable quality.
◆Optional drill rod feeding arm driven by rotation motor with braking, which could reduce labor intensity, is available.
