Product Description

YT28 Hand Held Air Leg Rock Drilling  for Horizontal Drilling

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 Hand Held Air Leg Rock Drilling Machine

 

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 large-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 Hand Held Air Leg Rock Drilling Machine

 

YT28 Hand Held Air Leg Rock Drilling Machine is widely used in mining, tunneling and various drilling operations. Me

tallurgy, coal, railway, transportation, water, infrastructure and defense stonework projects in key equipment. The ma

chine 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 in

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.
