|
| Place of Origin | GERMAN |
| Brand Name | Shanghai Rotorcomp |
| Certification | ISO.TUV,CE,GS |
| Model Number | KG940A |
Our KG940A high pressure crawler drilling rig has optimized hydraulic system, drill arm components, and carriage parts on the basis of KY140A crawler drilling machine. Specifically, The KG940A type machine has 14% higher rotation speed, and 10% larger propulsion length, making it quite a cost-effective choice.
Advantages of KG940A compare with KY140A
| KG940A | KY140A | Advantage | |
| Sliding carrier | Thicker and stronger sliding carrier, lower friction platen | Channel steel sliding carrier | Higher rigidity and lower friction |
| Walking parts | Walking reducer (with hydraulic brake) from China | Imported walking reducer (hydraulic and mechanical dual braking system) | Stronger gradeability and more reliable braking system |
| Hydraulic system | 28.2 pump | 32 pump, large new type valve group, new type connector, walking boom | Higher flow, lower resistance, convenient operation, and better appearance |
| Pneumatic system | Ball valve | Slide valve type impacting gas valve | Better operating experience |
| Rotation speed | 62r/min (diesel engine: 1700r/min) | 71r/min (diesel engine: 1700r/min) 100r/min (diesel engine: 2400r/min) |
14% higher rotation speed |
| Feeding speed | 530mm/s | 580mm/s | 10% higher feeding speed |
