The KG430, KG430H down the hole drill rig for open use is an improved device in
compliance with national regulations on
environmental protection. Equipped with Yuchai engine(China III), the drill rig meets
national standards for emissions
and environment.
The tramming motor of plunger piston and four-wheel drive improve
the working pressure and climbing
capacity. The expanded pitch and lifting-arm hydraulic cylinder enable it to meet the
requirements of limiting position
use. Meanwhile, the hydraulic system is improved, thereby proving increased system flow
and rotary speed.
The hydraulic
cylinder has been optimized, thus making it more reliable. The guide rail is installed
in an inclined way, making
operations and observations easier.
The thickened profile is used for the housing;
and the additional ring makes
handling and lifting convenient.
