Medium Pressure Crawler Drilling Rig

Our KY120 medium pressure crawler drilling rig is a kind of well designed mining equipment. See the details below, and contact us if you are interested in our product.

1. Humanization design

The rocker arm type walking operating mechanism of this borehole drilling machine can be operated at its side and back, so the crawler drill is typically suitable for running on mountain roads. The Specially designed casing is beautiful and easy for repairing.

2. Flexible drill arm
The movable drill arm can adjust the drilling angle and hole's height by controlling the stretching length of the oil cylinder. Thus the medium pressure crawler drilling rig can drill holes in a wider range with better drilling performance.

3. Reliable hydraulic system
An oil cooling device is added to reduce the oil's thermal influence on the entire hydraulic system.
