Oil and Gas Operation
ORV series breakers utilize a combination of oil pressure and flow from the carrier with gas pressure from
the breaker, an operating principle that has proven to be the most efficient working technology in the industry.

Auto-lube
A central grease port with internal grease passage Original holding system
readily adapts the hammer to most auto lube systems. The powercell is securely held inside
the bracket with the head damper,
reducing recoil.

Main valve ORV Series hydraulic breakers are the result of decades of field experience and Okada's long-standing
The internal control valve system equates to record of leadership in the industry. Thirteen models of ORV hydraulic breakers provide a broad range
faster speeds and higher impact energy of solutions for your skid steer loaders, compact excavators, tractor loader backhoes and excavators.
