In order to perfect the environment friendly drilling rig series and meet the requirements of small and medium mines for dust collecting drilling rig, Zhejiang Kaishan Engineering Machinery Co., Ltd. successfully develops KGH4/YCH4 Surface DTH Drilling Rig.

The drilling rig is equipped with mature two-stage coarse and fine dust separation and collection system with good dust collection effect and stable performance. Its drilling diameter is Φ80 ~Φ115mm and its drilling angle is the same with that of KG925 to drill blast holes and anchor holes of various angles, including horizontal, inclined and vertical holes.

Thanks to its stable performance, wide application scope, and high performance-cost ratio, KGH4 drilling rig is the first choice for environmental protection and transformation in small and medium mines.

Characteristics of KGH4/YCH4 Surface DTH Drilling Rig:

1. The dust collecting system driven by imported high-speed motor runs stably to collect dust effectively;

2. It is equipped with extended guide rail with the first rod of 3m;

3. Its running system is reinforced to be solid and durable;

4. Its integrated control console is flexible and convenient with elegant appearance;

5. Super high rotation speed (max. 140r/min) accelerates the drilling speed in soft and medium rock.
