INTRODUCTION:
The Marion Rotary Blast Hole Drill uses a tri•cone rock qit for the drilling of holes to accept
an explosive material. The denotation of the “charge” breaks the rock and loosens the over·
burden. The rotary bit threads to a drill pipe section that threads to a direct current
electric motor on the rotary gearbox on the mast. The rotary gearbox provides torque and
rotary speed to the drill bit. A roller chain hoist-pull down system, powered by two
hydraulic motors, raises and lowers the rotary gearbox and provides a load (or force) to
the drill bit.
- The drill air compressor uses a rotary vane impeller to supply air down thru the drill
pipe and thru the drill bit. This bailing air cools the bearings in the drill hit and
removes the drilled material cuttings from the hole. - A leveling system provided on the machine permits the operator to level the machine before each
drilling cycle. The leveling jacks (cylinders) are controlled in the opf;lrator’s cab with
jack location front and rear at each side of the machine. - The machine is equipped with an independent propel system which uses a hydraulic motor on
each crawler. The operator is afforded control of each crawler separately to permit ex·
cellent machine maneuverability. - The hoist•pull down and propel hydraulic circuits are included in the main hydrJuiic system. This
system is po ered by a 200 horsepower motor geared to two variable displacement
axial piston pump
