HYDRAULIC OPEN AIR BLAST HOLE DRILLING RIG
|
RÖKK B55 drilling rig
① Floating chassis
② Boom structure
③ Dust collector
④ Hydraulic hose lines
[FLOATING CHASSIS]
ROKK B55 drilling rig is fitted with floating chassis and single gear crawler plate with strong ground grabbing capability so as to facilitate travelling quarry or mining site. Imported hydraulic motor can guarantee strong drive force and increase climbing capability for better maneuverability and suitability
[OPERATING SYSTEM]
Operating handles enable centralized control and simple operation. The system has travelling pilot function so as to system efficiency and reduce loss time as well. In the meanwhile, the entire machine is fitted with double-position operating system, which makes operator manipulate it during transition.
[ENGINE]
Cummins 60KW diesel engine is industrial type, which provides strong power to the hydraulic pump and motor for stable operation of drilling rigs. .
[DRILLING ARM STRUCTURE]
Simple and robust drilling arm structure reduces carriage hinging points and enhance drilling stability.
[HYDRAULIC HOSE LINES]
The hydraulic hose lines are well arrayed with ties. In the meanwhile, drilling rack is fitted with accompanying tow chains so as to protect air ducts and oil pipes of motor.
