Socket anchors are used mainly for lifting concrete elements. The anchor has an internal thread and is manufactured from steel pipe with a hole drilled for anchoring with a ribbed metal rod. In order to prevent concrete from seeping into the thread, a plastic cap can be fitted to the base of the thread (HA), or the socket can be flattened (HAL). The HAL plate anchor has a metal plate welded to the bottom end and is especially designed for lifting tile-like concrete elements. Due to its compact design, the anchor is suitable for all types of concrete objects.
By using these internally threaded anchors along with suitable wire rope lifting loops the time consuming jobs of patching and cutting ribbed steel lifting loops is eliminated on construction sites. The wire loops are simply detached from the element and the hole is capped. This greatly eases and reduces the assembly time of concrete elements.
The benefits and specifications of socket anchors
- suitable for lifting all types of concrete elements
- saves time compared to conventional methods
- element weight can be up to 0,5t - 12,5t per anchor
Depending on the final use, the internally threaded sockets can be galvanized or made from stainless steel.
