Underground Mining Equipment
Hydraulic Drilling Jumbos, HT81(for Tunelling and Cavern Excavation)
HT81 hydraulic drilling jumbo has been engineered for various mines and medium sized drifts & tunnels, with drilling coverage range of 4000x4000-6100x6100mm (WxL).
The drilling machinery comes with fully hydraulic rock drill system and anti-jamming function, allowing for quick drilling speed with low consumption. The drilling jumbo is featured by compact structure and great mobility. In addition, large quantities of dust will be produced during drilling. Huatai adopts efficient dust control measure. The water is used for hole flushing during rock drilling, minizing dust generation. This provides a comfortable and safe working environment.
