A setting tool and liner hanger for setting a liner in a well bore traversing earth formations is described including: a tubular outer hanger member adapted for coupling to a depending liner, the outer hanger member having circumferentially disposed elongated slip openings, elongated slip members disposed in the slip openings for movement of the slip members from a first retracted position within the outer hanger member to an extended position in engagement with the wall of a well casing, a setting tool having a tubular inner member adapted for coupling to a drill string; hydraulic slip setting means for response to hydraulic pressure for producing a slip setting force and mechanical slip setting means for producing a slip setting force, the hydraulic slip setting means and the mechanical slip setting means being carried by the tubular inner member; coupling means for releasably coupling the tubular inner member to the outer hanger member. The slip setting means include an upper dog member and a lower dog member which are respectively connected to the hydraulic slip setting means and to the mechanical slip setting means wherein the dog members are movable longitudinally relative to the tubular member in response to a slip setting force for moving the slip members from the first retracted position to the extended position. The hydraulic slip setting means and the mechanical slip setting means for moving the upper and lower dog members respectively include selectively operable actuator means for selectively moving one of the dog members longitudinally relative to the tubular inner member and the outer hanger member.
