Feature:
YT29A is powered by compressed air, with centralized operating mechanism, flexible start, air-water linkage, convenient use, simple maintenance, low noise, small vibration, energy saving and high efficiency, long service life of parts, high versatility, good reliability, high efficiency, strong function of purging blast holes and large rotating torque, so it is worried about similar products. It is mainly used for drilling, blasting and anchor cable holes in earth rock engineering.
Application:
tunneling and support in mining, transportation, water conservancy, hydropower and other projects. It is mainly used for quarries - dividing rocks.
Our air-leg rock drills have following features:
1. Fit for wet drilling in medium-hard or hard rock
2. Grouped control mechanism, quick to start up, with "air on, water on, air off, water off" mechanism, convenient to handle and easy to maintain and repair.
