1、 Overview
Product Features and Uses
The YT29 (T) air leg rock drill is a new type of high-efficiency rock drilling machine with light weight, low noise, superior rock drilling performance, and convenient operation and maintenance. This machine is widely used in mining, tunnel excavation, and various rock drilling operations to drill blasting holes. It is an ideal tool for metallurgy, coal, railway, transportation, water conservancy construction, and national defense rock engineering.
This machine is suitable for drilling horizontal and inclined rock holes on medium hard or hard (f=8-18) rocks, with a diameter of generally 34-45 millimeters and an economical large drilling depth of 5 meters. This machine can be used in conjunction with the FT160BD short air leg and FT160BC long air leg according to the size of the tunnel section, or can be installed on a drilling truck or drilling frame to work.
