YT28（Air-leg）rock drill product features

1、The height of the machine is moderate and the range of the stroke is large, so it can drill the anchor holes which are perpendicular to the roof surface, which solves the problem that the anchor holes in the roadway are not perpendicular to the surface of the roof for a long time, which guarantees the quality and progress of the project, saves the construction cost and improves the efficiency.
2、Good comprehensive rock drilling performance, not only for medium hard rock drilling, but also for rock drilling with f≤6, which can be applied to both rock roadway and quasi roadway.
3、Simple structure and more durable, easy to maintain, lower maintenance cost
4、Flexible start, air and water linkage, air leg fast return, air pressure adjustment and other institutions.
5、The control handle is concentrated with the shank body, the mechanism is novel and convenient to operate with the muffler cover can effectively reduce the noise and change the direction of the row of visits at will to improve the site The operation conditions of the field
6、YT28 rock drill is suitable for wet rock drilling of medium hard or hard rock.

Application

Tunneling and support in mining, transportation, water conservancy, hydropower and other projects. It is mainly used for quarries – dividing rocks.
