Specification :

The QL-Y28 Hydraulic rock drill is a hi-tech product driven by high-pressure hydraulic oil. it adopts advanced technology and novel structure, featuring low energy consumption, small size, light weight, hugeimpact energy, fast drilling, low noise, little vibration, trivial labor intensity.It is widely applied to drill mines of marble, granite, metal, non-metal and coal mines.

Drilling performance:applicalbe to hard, semi-hard and soft rocks; drilling diameter from 36mm to 50mm, while drilling ganite of rigidity 7.6 degree, the drilling speed can reach over 800mm-1000mm/min, depth up to 9m. Its efficiency and performance overmatch foreigh counterparts.

The hydraulic rock drill is composed of three parts:
1. Hydraulic hammer drill
2. Hydraulic power station(Anti-blast model, Non anti-blast model and diesel engine model)
3. Handheld air-driven or vertical and horizontal hydraulic rock driving system. ground jack type.

According to different engineering requirements, we can offer various supporting devices, such as manual handheld rack, air ground jack, horizontal rack for mining marble and vertical rack, and railway rack for mines, which are for different working conditions.
