The use of these two types of transport anchors is covered by the CEN/TR 15728 state-of-art-report on the “Design and Use of Inserts for Lifting and Handling” [4], which, however, has not been implemented in Germany due to safety concerns associated with the design of inserts for lifting and handling (transport anchors) in accordance with the methods specified in the report. However, the uniform use of transport anchor systems...
