HFGA-46+ Automatic Integrated Open-air DTH Drilling Rig

overview

Features

1. According to the different needs of users, high-quality diesel engines of Caterpillar, Cummins, Yuchai and top-quality double-pressure screw engines with a large displacement of at least 24 bar are used.

2. As the user's production equipment, each structure of this series of products has been double-safety heavy-duty design and the highest-end component configuration.

3. A stainless steel wear-resistant sleeve is used to protect the special pressed aluminum alloy propulsion beam and high-torque rotary head, and the large-aperture operation is realized on the basis of ensuring that the drilling rig is easy and flexible to operate.
