KG920A/B/D, KGH4 Medium Pressure Crawler Drilling Rig
The KG920A/B/D, KGH4 medium pressure crawler drilling rig is an updated version of KY125 series rock drilling machine. The pneumatic system, hydraulic system, drill arm components, walking parts are all optimized and upgraded. Thus the machine has stronger gradeability, and the steepest slope could be in 30°. Besides, the rotating speed could be from 0r/min to 107r/min.
A detailed comparison between the KG920A/B/D, KGH4 and KY125 drilling machinery has been made in the form below. You can see the advantages of our KG920A/B/D, KGH4 medium pressure crawler drilling rig clearly. If you are interested in it, just contact us at any time.
Advantages of KG920A/B/D, KGH4 over KY125(D)| | KG920A/B/D, KGH4 | KY125(D) | Advantage |
| Walking parts | Motor and reducer | Ball piston motor (direct connecting) | Less pressure and longer service life for the motor |
| Walking pressure | 11Mpa | 14-16Mpa | |
| Drill arm | New type drill arm | | Drilling horizontal and vertical holes at the same time, low height of the horizontal hole |
| Pneumatic systems | Live type impacting air valve | Ball valve | Easier control |
| Rotation speed | 83r/min (diesel engine 1700r/min) 107_n (diesel engine 2200r/min) | 55r/min | 50% higher rotation speed |
| Hydraulic system | 30 pumps, large new type valve group, new type flow divider, new type connector | 16 pumps | Higher flow, lower resistance, and better appearance |
| Feeding speed | 450mm/s | 336mm/s | 40% higher feeding speed |
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.
Feature
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.
