ABSTRACT:
A liner hanger has a housing with a pocket disposed on an inner wall surface and a slip slidingly engaged within the pocket. A moveable cover is disposed interior to the slip thereby restricting movement of the slip from a unset position to a set position. The liner hanger housing is secured in the string of casing and an actuator is mounted on the liner. As the liner is moved through the casing coupler, the actuator actuates the cover, causing the cover to be moved so that the slip can move axially downward from its unset position to its set position. As the cover is moved, the slip moves radially inward and grips the liner to secure the liner within the casing string of the wellbore.
