Abstract
A lifting anchor for embedment into a concrete component, the anchor having a head for releasable engagement with lifting equipment, and at least one leg extending from the head, the leg being profiled so as to lock into the surrounding concrete, wherein the profiling is formed by a series of formations arranged along at least a face and adjacent edge of the leg.
Claims18
A lifting anchor for embedment into a concrete component, the anchor comprising:
- a head configured to releasably engage with lifting equipment, the head including a front surface and a rear surface opposing the front surface, the head defining an eye extending through the front surface and the rear surface;
- and
- a first leg extending from the head, the first leg having a profile configured to lock into concrete of the concrete component that surrounds the first leg when the lifting anchor is embedded in the concrete component,
- wherein the profile includes a series of formations that forms a front surface of the first leg and an edge of the first leg adjacent to the front surface, and
- wherein the front surface of the head and the front surface of the first leg face the same direction.
An edge lift anchor for embedment into a concrete panel, the anchor comprising:
- a head configured to releasably attach with lifting equipment, the head including a front surface and a rear surface opposing the front surface, the head defining an eye extending through the front surface and the rear surface;
- and
- a pair of generally parallel legs extending from the head, each of the pair of legs having a profile configured to lock into concrete of the concrete panel that surrounds said leg when the lifting anchor is embedded in the concrete panel,
- wherein the profile includes a series of formations that forms an inner edge of said leg and opposed surfaces of said leg, and
- wherein the front surface of the head and one of the opposed surfaces of each of the pair of legs face the same direction.
A lifting anchor for embedment into a concrete component, the anchor comprising:
- a head configured to releasable engage with lifting equipment, the head including a front surface and a rear surface opposing the front surface, the head defining an eye extending through the front surface and the rear surface;
- and
- a first leg extending from the head, the first leg having a profile configured to lock into concrete of the concrete component that surrounds the first leg when the lifting anchor is embedded in the concrete component,
- wherein the profile includes a series of formations that forms a front surface of the first leg, and
- wherein the surface of the head and the front surface of the first leg face the same direction.
A lifting anchor for embedment into a concrete component, the anchor comprising:
- a head configured to releasably engage with lifting equipment;
- a leg extending from the head, the leg including a profile configured to lock into concrete of the concrete component that surrounds the leg when the lifting anchor is embedded in the concrete component;
- and
- reinforcing ribbing extending the outer edge of substantially the entire length of the leg.
An edge lifting anchor for embedment into a concrete panel, the anchor comprising:
- a head configured to releasably attach with lifting equipment;
- and
- a pair of generally parallel legs extending from the head, each of the pair of legs including a profile configured to lock into concrete of the concrete panel that surrounds said leg when the lifting anchor is embedded in the concrete panel,
- wherein each of the pair of legs includes ribbing extending along an outer edge thereof over substantially the entire length thereof, the ribbing extending to adjacent the head of the anchor whereby the anchor is substantially configured in the manner of an I-beam from adjacent the head to the remote ends of the legs.
