Technical Specifications: KG420S/KG420SH
Rock Drill Model: 58kW/2200r/min
55kW/1460r/min
Drilling Diameter: 90-152 mm
Drilling Depth: 25 m
The KG420S/KG420SH DTH drill rig for open use is equipped with a dust collector,thus making operation more environment-friendly and reliable.
The folding frame track,four-wheel drive and the tramming motor of plunger piston improve the working pressure and climbing capacity.
The expanded pitch and lifting-arm hydraulic cylinder enable it to meet the requirements on limiting position.The double rotation motor increases the rotary torque and revolving speed, and the lifting hydraulic cylinder and chain are expanded to promote the lifting force and reliability.The thickened profile folder is used for the housing,thus improving its level of intensity and rigidity;and the additional ring make shandling and lifting convenient.
