1. Standard equipped with Yuchai 4-cylinderDiesel engine YC4D80 or 30 Kw electric motor for 3m drill rod with Φ68 mm or Φ76 mm, HFG-20 categorized according to the tramming system Dry dust collector for option.
2. All structural parts reinforced.
3. The rotation 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. High performance wet air filter together with two stage dry air filter for three stage air filtering system to protect diesel engine better.
5. New enclosure design for better appearance and convenient for maintenance and service.
6. Optional dry dust collector for dust free drilling, more environment friendly and energy saving.
7. HFG-20 standard equipped with plunger piston motor and national standard engineering machinery tramming track for greater climb ability and more reliable quality.
