stall and operate on the trolley or stand.



Work principle

Rock drill work, the air pressure alternately changes into the cylinder's back cavity and the front cavity, pushes the

piston to return movement. The same pressure also acts on the rear cover or front cover of the cylinder, which

causes the rock drill to retreat or advance, so that the rock-drilling machine produces vibration to produce a

hammering force.
