Cast-in Socket Lifting Systems

Cast-in socket lifting systems simplify the handling of precast concrete elements. Manufacturers embed these sockets directly into concrete during casting. Once cured, the sockets provide strong anchor points for lifting and positioning heavy components like wall panels, beams, and slabs. Joluka designs its cast-in sockets for both precast and in-situ concrete applications. These sockets allow contractors to fix concrete elements securely to surrounding structures. When used for lifting, each socket must be reinforced properly. A U-shaped rebar passes through the socket’s cross hole. This reinforcement spreads the lifting force into the concrete, preventing damage or failure. Joluka produces sockets from seamless precision tubes. Each socket is galvanized to resist corrosion. Stainless steel options are available for harsh environments. The sockets are compact but strong, typically measuring 4 × 4 × 12 cm and weighing around 0.7 kg. Their small size makes them easy to install during casting. Safety remains a top priority. Joluka recommends using these systems only for vertical lifting. Each socket must be fully threaded with a matching lifting loop or forged head. The system includes a safety factor of 5 to ensure reliable performance under load. Proper installation and reinforcement are essential to avoid accidents. Joluka offers a wide range of lifting solutions. These include cast-in sockets, lifting loops, flat foot sockets, and Socketfix systems. Each product serves a specific purpose in precast construction. Contractors can choose the right system based on load requirements, concrete type, and lifting method.
