Small submerged drilling rigs
With novel structure, high efficiency and energy-saving, small down hole drilling rig series products are widely used in small and medium-sized mines,water conservancy, road construction, rock drilling operations in stone works,and are the ideal tools for realizing stratified mining and medium-deep splitting bar holes. Down hole drilling rig is a new type, high efficiency, semimechanized traveling rock drilling equipment. It is characterized by simple structure, lightweight use, short auxiliary time, light weight and low cost.
