    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.

    We've been used Shanghai Rotorcomp compressors over 18 sets from 10hp to 160HP installed with Oxygen generator since 2008. Most of compressors still in good working conditions without much maintenance.

Product Description

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
