SD-545 Crawler Blasting Hole Drilling Rig Built-in Air Compressor

SD-545 integrated DTH drilling rig, an upgrade from existing mature model, with core components upgraded to world famous brands. Single power pack (only one diesel engine) drives both screw air compressor and hydraulic system with power output of stagger design.

Comparing with separated drills, the power consumption of diesel engine is reduced by 30% and maintenance cost down by 50%. The integrated designed of SD-545 for improved production efficiency without towed air compressor moving around with less air transmission loss and better long-distance fleet management.
