Product Description
HW421  integrated DTH drill rig operation platform, tramming components, hydraulic system,
feed beam & rotary head are upgraded from the original 410C tooptimize the functional capability of the drill rig.
The blast hole DTH crawler drill rig Piston tramming motor greatly increases the work life of tramming mechanism,
Upgraded operation platformcan be controlled by one operator instead of two, to increase the work efficiencywhile
lowering drilling cost.

1. Sandard euipped with Yuchai 4 cylinder Diesel engine for 3m drill rod with Φ60mm or Φ76mm, dry dust collector for option.
2. All stuctural parts reinfoced for various work conditions.
3. The roration unit driven by cycloid motor for more compact structure and low failure rate. Torque improved for larger hole range drilling and widely used for foundation bolting and anchoring, casing and large hole spiral drilling.
4. New enclosure design for better appearance and converient for maintenance and serice.
