Hydraulic Crawler Type Jumbo Rock Drill And Underground Mining
Borehole Machine
It is used for blasting holes and anchor rod hole operations in the
fields of metal mine excavation and tunnel excavation.
Workers stand in a safe place to operate it for rock drilling. This
equipment replaces traditional manual air gun drilling operations,
reducing worker labor intensity, improving work efficiency and
safety factor. Applicable to cross-section (width × Height):
5.4m*5.2m, with a climbing ability of ≤25% and a walking speed of
up to 2km/h. The working mechanism of this machine adopts full
hydraulic drive. The machine is lifting, compact in structure,
advanced in hydraulic system, easy to maintain, low in center of
gravity, flexible in movement, fast in rock drilling speed, stable
in operation, convenient in operation, and safe and reliable.
