Carriage parts

Box iron slide block

Enhanced carriage of thick liner plate reduces the wear of pressing plate. And the appearance is neater by adopting rubber-tube support chain

Enhance rigidity and reduce wear.

Walking parts

Domesticwalking reducer (Hydraulic Brake)

Imported walking reducer (Hydraulic/machinery dual-brake)

The gradeability is strong and the braking is reliable, so as to prevent slipping from the slope.

Hydraulic system

Applications

KG dth drilling rig series is revised on the basis of KY surface dth drilling machine series, which maintains the simple structure and stable performance of KY drilling rig series and upgrades the hydraulic system, travelling unit, gyrator, power, gas path system, drill arm component and rack unit, enjoying increased power, stronger climbing ability, more reasonable drilling angle, faster rotation and advancement speed, longer-term motor service life and better reliability. This rock drilling rig is widely used in blasthole drilling of large- and medium-sized open-air mining, water conservancy, power station and road paving projects. Applicable rock hardness: F=6-20, drilling diameter: 80-165mm, economic drilling depth: 12-25m.
