Medium Pressure Crawler Drilling Rig

This product has been discontinued and removed from our shelves.

The KG920B medium pressure crawler drilling rig is another new version updated on the basis of KY125 series machine. As a powerful construction machine, its pneumatic system, hydraulic system, drill arm components, walking parts are all optimized and upgraded. The YC4D80 type diesel engine (58KW, 2400r/min) was used to replace the original type. Thus the machine now can walk up a slope of 30°, and the rotating speed is also greatly enhanced. The drilling angle becomes more reasonable.

In the form below, you can see the advantage of our KG920A medium pressure crawler drilling rig over the KY125 crawler drill. If you are interested in it, just contact us at any time.
