SWDM 178A-DTH full hydraulic crawler mounted large diameter blast hole surface down-the-hole drill rig
SWDM 178A DTH is an efficiency hydraulic integrative drilling rig, which is suit for high-level and large-bore open-pit blasting operation with various rock hardness. Diesel and diesel-electric dual power are suit for different mine choices. Reasonable rotating speed and feed system are designed for different rock features to ensure high drilling efficiency. The machine designed by require of hole diameter and depth, which accurately set engine and compressor and exert maximum impact frequency of DTH impactor to accomplished ideal drilling economy. High operating rotating speed, large axial-load cutting drilling system were designed,which based on the working requirement related to soft rock. Matching medium or low pressure compressor to achieve drilling demand which need to be faster and more economic. It has a high drilling frame structure and four-point hydraulic expansion leg suitable for large-scale mining,which has excellent ground adaptability.
Product Description
FEATURES:
1.Cab of full hydraulic surface down-the-hole drilling rig
