Production
YT series rock drilling machine is a new and efficient rock
drilling equipment, widely used in tunnel excavation, stone
engineering, mining and various rock drilling operations, used to
drill blasting holes, and is an indispensable equipment in
railways, highways, metallurgy, coal, water conservancy and hydro
power construction and national defense stone engineering.
The YT series air leg drilling machine has a wide range of use. It
is suitable for drilling horizontal or inclined gun holes on
medium-hard or hard rocks (f=8~18), or drilling anchor holes on the
top plate vertically upwards. The diameter of the gun hole is
generally 34-45mm, and the effective depth of the drilling hole can
reach 5 meters.
