Claim 16:
17. A method, comprising:
forming a load anchor with an expandable mandrel, a sealing element disposed around the expandable mandrel, a plurality of radially expandable gripper members, and a plurality of beam springs positioned to act against the gripper members;
deploying the load anchor into a well tubing;
increasing pressure within the expandable mandrel to radially expand the expandable mandrel, thus radially expanding the radially expandable gripper members into engagement with the well tubing; and
protecting the sealing element against detrimental sliding motion with respect to the well tubing by providing the beam springs with engagement surfaces oriented to bias the radially expandable gripper members into more secure engagement with the well tubing upon axial loading of the expandable mandrel.
