Hydraulic Drilling Jumbo
A drilling jumbo is a key excavation tool used in traditional (NATM) and semi-mechanized tunneling, designed for drilling, blasting, and face preparation in hard rock. CREG models are typically designed with two or three booms and are equipped with either hydraulic control systems or fully intelligent automatic systems.
- Applications
- Rock Tunnels
- Underground Mines
- Excavation of Galleries and Ramps
- Metro Projects in NATM Sections
