Piston Pneumatic Rock Drill for Construction Industry

A kind of shock-drilling machine with compressed air as its driving force. According to the

propulsion mode is also divided into hand-held rock drilling machine, gas-leg rock drilling

machine, telescopic up-type rock drilling machine and guide-type rock drilling machine.

Introduction of YT28 Impact Type Pneumatic Rock Drill for  Rock Mining

YT28 Hand Held Air Leg Rock Drilling Machine is the most modern drilling machine which

uses a modern design techniques, compared with the same type of product, with high

efficiency, low noise, light weight, good economic results, the advantages of speed

footage. Its superior performance, is the most reliable, and it is most efficient

drilling machine. YT28 Hand Held Air Leg Rock Drilling Machine is most suitable for l

arge-scale mining, the medium-sized mines and tunnel drilling operations in the

domestic users respond to best in the Korean market share has reached 70% or more.

Application of YT28 Piston Pneumatic Rock Drill for Construction Industry

YT28 Hand Held Air Leg Rock Drilling Machine is widely used in mining, tunneling and 

various drilling operations. Metallurgy, coal, railway, transportation, water, infrastructure 

and defense stonework projects in key equipment. The machine uses the wet-hard or 

hard rock drilling operations, muzzle diameter of 34-42mm, drilling depth of up to 5m. 

With FT160A can drill air leg supporting horizontal and inclined blast holes; may install 

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.
