Description
Blasting Drill
Product Summary
The SMC-DTH-452H crawler hydraulic down-the-hole drilling rig has a fully optimized structure, lower footage cost, and more user-friendly design. It uses a diesel engine (motor)-hydraulic oil pump group as the power unit, 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 hole operations in hydropower projects, open-pit mining, road construction, and national defense projects.
