Main features of drilling rig
The JL598 crawler-type hydraulic down-the-hole drilling rig has a fully optimized structure, lower footage cost, and a more user-friendly design. A diesel engine (electric motor)-hydraulic oil pump unit is used as the power device, and the hydraulic motor realizes auxiliary actions such as drilling rig rotation, propulsion, lifting, walking, and hydraulic cylinder swing angle positioning.
Mainly used for drilling and blasting operations in hydropower projects, open-pit mining, and road construction projects.
