YT29A pusher leg rock drill is a heavy-duty pusher leg Rock Drill featuring high efficiency and low air consumption. It is primarily designed for drilling in mines, hydropower stations, and road construction projects. It is also a new product suitable for tunneling and other stone works in mining and metallurgical industry.

YT29A pusher leg rock drill is suitable for both horizontal and upward anchor holes in medium-hard and hard rocks (100–350 MPa). The hole diameter range is from 32 mm to 45 mm with depths up to 5 meters. The Rock Drill is equipped with lubricator FY250. YT29A is intended to be used together with pusher leg FT160A, FT160B, FT160C or FT170 for different tunneling and work conditions. It is also designed for dry drilling or wet drilling mounted on rigs.

Performance

1. More output power

2. Rock drilling speed is faster

3. Super strong lubrication system to ensure the long time operation of movement parts

4. The whole machine has optimized design, the impact energy and impact frequency have reached an excellent match, it is your ideal rock drilling tool.

5. Gas and water linkage, quick return of the gas leg, air pressure adjustment and other institutions.

6. Control handle centralized with Back head, the mechanism is novel and convenient to operate, the muffler cover can effectively reduce the noise and change the direction of discharge at will to improve the working conditions in the field.

Application

Mining, traffic, tunnels, water conservancy construction, quarries and other work

YT29A pusher leg rock drills are heavy-duty push-leg (air-legged) rock drills with low energy consumption, which are more suitable for drilling horizontal or inclined holes in medium-hard and hard (f=8-18) rocks, as well as drilling anchor holes upwards or downwards. It can be used with FT160A (or FT160B, 160C) according to the size of the roadway section and operating conditions, and can also be used with the drill truck or drill frame for dry or wet rock drilling.
