The integrated DTH drilling rig with air compressor combines drilling unit and air compressor into one complete set. Different from separate equipment, it requires no external air compressor, saving extra matching work and site space.
The integrated DTH drilling rig with air compressor combines drilling unit and air compressor into one complete set. Different from separate equipment, it requires no external air compressor, saving extra matching work and site space.
This all-in-one machine integrates walking, rotation, feeding and air supply systems. It features compact layout, flexible movement and strong site adaptability, perfectly suitable for mountainous areas, remote regions and scattered construction sites. With stable power output and excellent rock-breaking performance, it ensures high drilling efficiency and smooth operation.
The rig is easy to operate and maintain, with low overall failure rate. It supports adjustable drilling angles to cope with diverse working conditions. No extra supporting air supply equipment is needed, only standard accessories like drill rods and DTH hammers are required for normal use. It is an ideal choice for mobile and convenient field drilling operations.
