Anti-jamming, High speed drilling and drill steel economy, Telescopic heavy-duty boom, Wheels for easy moving in narrow tunnels - details see: https://www.machineto.com/mining-face-drilling-rig-10319364

Designed and manufactured by Zhangjiakou Xuanhua Huatai Mining & metallurgical Machinery Co., Ltd., HT81A wheel type hydraulic drilling jumbo is mainly used to drill blastholes for tunneling constructions in coal mine, non-ferrous metal mine, hydro-power station, railroad, highway engineering etc. Advanced hydraulic rock drill system, anti-jamming mechanism make it has rapid drilling speed and high efficiency. Flexible mechanism can make the jumbo drilling on face, slope, roof, side wall and floor in underground mine or tunnels. This small compact jumbo has a low center of gravity, great mobility, remarkable stability and strong gradeability, thus can be improve working environment and get efficiency, quality development.
