Feature

A. The rig speed range is 27-901r/min, and the maximum output torque is 10,500N.m.
B. The drilling machine adopts a long-stroke speed doubling mechanism and a mechanical power head with a stroke of 3500MM, 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 and drilling. Less power loss, short auxiliary time.
D. Track chassis, leg cylinder travel 1.5m can be automatically loaded, easy to move and transport.
E. The rig reserves some functional interfaces in the mechanical hydraulic system, which can be expanded according to the process requirements of different users.
