PD-Y28 Pneumatic Rock Drill Attachment for Mini 4 tons Excavator

PD-Y28 Excavator Attached Pneumatic Rock Drill changes the tradition of manual hand-held  pneumatic rock drills.Y28 is installed on a rail that can swing and move up and down, and then the rail is installed on the excavator with a quick-change connector. PD-Y28 drilling operation still uses air compressor to drive Y28 for drilling, but the drilling angle and the movement of the rock drill are derived from the hydraulic power of the excavator, which is controlled by the imported electromagnetic control valve sets. The operator uses electric control box knob controls the drilling operation in the cab, which is convenient, fast, safe and efficient. PD-Y28 improves the working environment, work efficiency and reduces labor intensity.

Application field: It is widely used in marble quarrying, tunnel boring, stonework, mining and various rock drilling operations. It is an indispensable operating tool in railway, highway, metallurgy, coal, water conservancy and hydropower construction and national defense stonework.
