    Mr.Kerry Robinson from Australia
    today I ran the compressor and I am very happy with the workmanship and the quality , it is connected to a nitrogen generator that requires around 0.8 MPA feed air from the 30 kw compressor we are commissioning it I have found that it loads and unloads from 25.5 kw - 30 kw this will be a huge saving on power consumption.

Product Description

Based on our previous product KG925 borehole drilling machine, we developed this KGH4 medium pressure eco-friendly crawler drilling rig. The new product comes with a dry type dust collector, and the drill bit diameter ranges from 80mm to 115mm. This crawler drill rig can drill blastholes (such as pre-splitting blasting hole) and anchor cable holes in horizontal, vertical and inclined directions. The attractive features of this blasthole driller like stable performance, wide application, high cost-effectiveness, makes our KGH4 medium pressure eco-friendly crawler drilling rig an ideal choice for medium and small mines.



1. The imported high-speed motor is used for the dust collecting system. The system is stable and efficient.
2. The guide rail is lengthened, and the first drill rod of the crawler drilling rig is 3m long.
3. Special treatment has been conducted on the walking system, making the system strong and durable.
4. The ultra-high rotating speed can reach 140r/min, making the drilling speed greatly accelerated.
