Claim 8:
9. A method, comprising:
conveying a liner hanger system downhole into a cased wellbore, the liner hanger system comprising:
a tubular body;
a plurality of lower slips mounted along the tubular body;
a spring cone disposed around the tubular body and fixed to the plurality of lower slips, the spring cone comprising:
a spring including a plurality of slots;
a lock ring including a ratchet profile, wherein the lock ring is disposed between a first slot and a second slot of the plurality of slots; and
a cone profile; and

a packer element disposed around the tubular body, below and adjacent the spring cone, the packer element comprising an elastomeric element;

actuating the plurality of lower slips against the cone profile of the spring cone to create a setting load that forces the plurality of lower slips radially outward into engagement with a casing, and compresses the spring cone; and
transferring the setting load through the spring cone to energize the packer element to seal an annulus between a liner and the casing,
wherein the lock ring having the ratchet profile prevents the spring cone from moving in an upward direction after compression.
