A system for use in a well, comprising: a load anchor having: a mandrel with an interior passage, the mandrel being constructed with a thin-walled tube section bounded by thicker walled ends, wherein the mandrel is configured to be radially expanded by deploying a setting tool within the mandrel to deliver hydraulic fluid under pressure into the interior passage causing plastic deformation of at least the thin-walled tube section as the mandrel is radially expanded; a plurality of beam springs secured along an exterior of the mandrel by retention mechanisms; an elastomeric sealing element disposed about the mandrel and trapped between abutments in an axial position, wherein the abutments are provided by compression rings disposed at either side of the elastomeric sealing element, a pair of end rings mounted around the mandrel; two wedge rings each comprising two angled surfaces, each wedge ring being wedged between a given end ring and a given compression ring on either side of the elastomeric sealing element via the two angled surfaces; and a plurality of gripper members disposed about the mandrel, each gripper member being axially bounded by a fixed angle section on one side and an angled section of an adjacent beam spring on the other side, each gripper member being positioned such that upon radial expansion of the mandrel, the adjacent beam spring is able to transform axially and to force the gripper member in an axial direction against the fixed angle section, the fixed angle section driving the gripper member radially outward against a surrounding surface, wherein the fixed angled sections block axial shifting of the sealing element regardless of the direction of axial loading on mandrel. a mandrel with an interior passage, the mandrel being constructed with a thin-walled tube section bounded by thicker walled ends, wherein the mandrel is configured to be radially expanded by deploying a setting tool within the mandrel to deliver hydraulic fluid under pressure into the interior passage causing plastic deformation of at least the thin-walled tube section as the mandrel is radially expanded; a plurality of beam springs secured along an exterior of the mandrel by retention mechanisms; an elastomeric sealing element disposed about the mandrel and trapped between abutments in an axial position, wherein the abutments are provided by compression rings disposed at either side of the elastomeric sealing element, a pair of end rings mounted around the mandrel; two wedge rings each comprising two angled surfaces, each wedge ring being wedged between a given end ring and a given compression ring on either side of the elastomeric sealing element via the two angled surfaces; and a plurality of gripper members disposed about the mandrel, each gripper member being axially bounded by a fixed angle section on one side and an angled section of an adjacent beam spring on the other side, each gripper member being positioned such that upon radial expansion of the mandrel, the adjacent beam spring is able to transform axially and to force the gripper member in an axial direction against the fixed angle section, the fixed angle section driving the gripper member radially outward against a surrounding surface, wherein the fixed angled sections block axial shifting of the sealing element regardless of the direction of axial loading on mandrel.
