Product Description Rock drills work according to the principle of impact crushing. During operation, the piston undergoes high-frequency reciprocating motion, continuously impacting the drill tail. Under the action of impact force, the pointed wedge shaped drill bit crushes the rock and chisels it into a certain depth, forming a dent. After the piston returns, the drill bit rotates at a certain angle, and the piston moves forward. When it impacts the drill tail again, a new dent is formed. The fan-shaped rock block between two indentations is sheared by the horizontal force generated by the drill bit. The piston continuously impacts the tail of the drill bit and continuously inputs compressed air or pressure water from the center hole of the drill bit to discharge the rock slag outside the hole, forming a circular drilling hole of a certain depth. Montabert brand rock drills are currently the leading brand of rock drills, with mature technology, leading technology, and excellent quality. They are widely used in various fields such as mining, tunnel excavation, water conservancy engineering, and road construction. They have the characteristics of high efficiency and high return rate, and can effectively reduce engineering risks and labor intensity.Power classkw21Hole range(typical) (mini-maxi)mm45-76Strike flow (mini-maxi)l/mn95-118Strike pressure (mini-maxi)bar 165-200Strike frequency (mini-maxi)Hz55-63Energy per blow (mini-maxi)J252-330Power out (mini-maxi)kw14-21Percussion inlet power(mini-maxi)kw26-39Rotation motor capacitycm3100/125/160Rotation flow motor maxil/mn48/60/75Max.rotation speed motort/mn303/296Max.rotation torque motorNm477/597/764Max.rotation pressurebar 210Water flushing pressure (mini-maxi)bar 14-24Water flushing flow (mini-maxi)l/mn60-120Front guide lubrication pressurebar 3Front guide lubrication air flowl/mn300Front guide lubrication oilcm3/mn0.5Accum.Nitrogen pressure HPbar 60Accum.Nitrogen pressure BPbar 5Recommended oil viscositycstISO46Oil viscostiy at working temperature (mini-maxi)cst15-30Oil operating temperature (mini-maxi)oC50to75Thrust feed force (mini-maxi)N11000-13000Collaring feed forceN9000Collaring strike pressurebar 110Percussion Back pressure Recomended without drainbar <5Recommended with drainbar <5Maximum working without drainbar 5Maximum working with drainbar 12Rotation back pressure(maxi.)bar 30ExternalHP line pressure(mini-maxi.)bar NOt AvailableExternal HP flow approximate when no percussionl/mnNOt AvailableDrain pressure(maxi.)if equippedbar 2Drain flow approximate if equippedl/mn10Maxi.Retract force with reverseNNot AvailablePercussion(optional)at 100 barAttention: Please consult us before using specific oil(non-inflammable, biodegradable,...).
