Feature

A.The rig speed range is 33-1120r/min, and the maximum output torque is 9800N.m.
B.The drilling machine adopts a long-stroke speed doubling mechanism and a mechanical power head with a stroke of 2300MM, which is used to improve drilling efficiency and reduce the occurrence of drilling blocking and burning accidents.
C. The rig uses double oil pump for oil supply, single pump is used when drilling, and the combined flow of double pump is used when lifting drill. Less power loss, short auxiliary time.
