YT28 airleg rock drilling is one of new high-efficiency machine used widely in mine roadway constructions and several of rock hole blasting. It is an important machine for relevant industrial construction and national defense project.
It is applied in many ranges and drills hole in horizontal and inclined direction. The diameter of hole is between 34-42mm with an effective 5 meters hole depth.
FT160 is one of new double-grade air leg through multiple tests. Its characteristic is light, sealed well, as well as expansion retractile and reliable, with the performances prior to the other drilling machine.
The pipe of air leg is a part compliant with safety standards, and shall not be causally replaced during use
