lifting socket for precast lifting sockets concrete
Lifting sockets are specialized devices used in the precast concrete industry to facilitate the handling, transportation, and placement of precast elements such as beams, wall panels, and floor slabs. These sockets are designed to be embedded in the concrete during the casting process, allowing for efficient lifting and moving of heavy concrete components.
Types of Lifting Sockets
- HSB Lifting Socket: This socket features a round end with a cross-drilled hole, designed specifically for lifting precast concrete units. It requires a reinforcement bar to effectively transfer the load into the concrete. The HSB lifting socket is available in various sizes with safe working loads ranging from 500 kg to 12,500 kg, depending on the model.
- Waved Lifting Sockets: These sockets have a wavy shape that enhances force transfer into the concrete, making them suitable for moderately thick precast elements. They are typically made from steel and come in various sizes with threaded or round threads. The preferred lift angle for these sockets is ≤30°, which is crucial for ensuring safe lifting operations.
- Socket Lifting Anchors: These anchors are particularly useful for thin precast elements and can handle high load capacities (up to 250 kN). They consist of a round steel anchor-foot with a threaded sleeve that allows for secure attachment of lifting devices.

Applications
Lifting sockets are integral to various stages of precast concrete construction:
- Demolding: They allow for safe removal of precast elements from molds.
- Transporting: Sockets enable easy lifting and moving of heavy concrete pieces on-site or during transport.
- Placing: They help position precast elements accurately in their final locations.
Specifications
Lifting sockets come with different specifications based on their design and intended use:
- Load Capacity: Ranges significantly depending on the type of socket, from 500 kg to over 12,000 kg.
- Materials: Commonly made from galvanized steel or stainless steel to withstand harsh environmental conditions.
- Dimensions: Vary by model, with specific height and diameter measurements tailored to fit different applications.
In summary, lifting sockets are essential tools in the precast concrete industry, designed to enhance safety and efficiency during the handling of heavy concrete components. Their varied designs cater to different lifting needs and specifications, ensuring they can be used across a wide range of applications.
