A casting socket or lifting socket is a specialized component used in construction and precast concrete applications to facilitate lifting, handling, and positioning of heavy precast elements like panels, beams, or blocks. These sockets are embedded into the concrete during the casting process and provide a secure point for lifting.

Types of Casting Sockets / Lifting Sockets

1. Threaded Sockets:
   • Made with internal threads.
   • Used with threaded lifting bolts or eye bolts.
   • Typically made of steel or stainless steel for strength.
2. Loop Sockets:
   • Designed with a loop or eye for hooking lifting equipment.
   • Common in heavy-duty applications where threaded systems are impractical.
3. Flat End Sockets:
   • Feature a flat base for secure anchoring in the concrete.
   • Ideal for flush mounting.
4. Recessed Sockets:
   • Designed to sit flush with or slightly recessed into the concrete surface for aesthetic or safety reasons.
5. Anchor Plate Sockets:
   • Feature an attached anchor plate for additional stability and load distribution.

Materials

• Steel (Galvanized or Non-Galvanized): For high strength and durability.
• Stainless Steel: For corrosion resistance, especially in marine or high-moisture environments.
• Plastic or Polymer (as inserts): To hold the socket in place during casting, later removed for access.

Applications

• Precast Concrete Lifting: Safe handling and transportation of precast elements.
• Structural Components: Beams, panels, columns, and slabs.
• Marine and Offshore: For anchoring and lifting in corrosive environments.
• Infrastructure Projects: Bridges, tunnels, and large-scale commercial buildings.

Benefits

• Safety: Provides a reliable lifting point, reducing the risk of accidents.
• Efficiency: Simplifies the handling and installation of precast elements.
• Versatility: Available in various sizes and configurations to suit different load capacities.
• Reusability: Some systems allow for reusable lifting components, reducing costs.
