Our KG930A high pressure crawler drilling rig is the update version of KY130 series open-pit mining machinery. It has optimized hydraulic system, drill arm components, and carriage parts. In comparison to the KY130 crawler drill, the KG930A type has 50% higher rotation speed, and 10% larger propulsion length. Thus the drilling performance is accordingly enhanced.
Advantages of KG930A compare with KY130
| KG930A | KY130 | Advantage | |
| Engine | YC4D80 | QC498 | More powerful,stable |
| Drill arm | New type drill arm | Drilling horizontal and vertical holes at the same time; low height of the horizontal hole | |
| Hydraulic system | 30 pump, large new type valve group, new type flow divider, new type connector | 19.2 pump | Higher flow, lower resistance, and better appearance |
| Sliding carrier | Thicker and stronger sliding carrier, lower friction platen | Channel steel sliding carrier | Higher rigidity and lower friction |
| Oil pump | 32 | 28.2 | Bigger air flow |
| Rotation speed | 90r/min (diesel engine 1700r/min) 120r/min (diesel engine 2200r/min) | 55r/min | 50% higher rotation speed |
| Feeding speed | 580mm/s | 530mm/s | 10% higher |
