適用范圍：This Technical Report provides recommendations for the choice and use of cast-in steel lifting inserts, hereafter called 'inserts' for the handling of precast concrete elements. They are intended for use only during transient situations for lifting and handling, and not for the service life of the structure. The choice of insert is made accordingto the lifting capacity of their part embedded in the concrete, or may be limited by the capacity of the insert itself and the corresponding key declared by the insert manufacturer. The report covers commonly used applications (walls/beams/columns and solid slabs and pipes) and the range of these applications is further limited to preventother types of failure than concrete breakout failure (cone failure), failure of supplementary reinforcement or failure in the steel insert. A basic supposition is that the concrete is demonstrably uncracked during all lifting situations.The limitation in scope is used to obtain simple design models. Further information may be found in [1].The recommended safety levels are intended for short-term-handling and transient situations.This Technical Report applies only to precast concrete elements made of normal weight concrete andmanufactured in a factory environment and under a factory production control (FPC) system (in accordance with EN 13369:2004, clause 6.3) covering the insert embedment.This Technical Report does not cover :? The design of the insert itself (for inserts manufactured by insert suppliers).? The lifting key that hooks on to the embedded lifting insert as a component between the insert and the liftingmachinery (crane, excavator…), nor its compliance with the embedded insert. These components, whenbrought to the market separately, are covered by the Machinery Directive (98/37/EC).? Lifting inserts for permanent and repeated use.This report is not an interpretation of the Machinery Directive.
