BS PD CEN/TR 15728:2016 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 onlyduring transient situations for lifting and handling, and not for the service life of the structure. Thechoice of insert is made according to the lifting capacity of their part embedded in the concrete, or maybe limited by the capacity of the insert itself and the corresponding key declared by the insertmanufacturer.

The report covers commonly used applications (walls/beams/columns and solid slabs andpipes). The range of these applications is further limited to prevent other types of failure thanconcrete breakout failure (cone failure), bond failure, failure of reinforcement or failure in thesteel insert.

Due to lack of information this report does not cover double shell walls, floor plates and beams forbeam-and-block floor systems.

The safety levels are given for information and are intended for short-term-handling and transientsituations.

This Technical Report applies only to precast concrete elements made of normal weight concrete and manufactured in a factory environment and under a factory production control (FPC) system (inaccordance with EN 13369:2013, 6.3) covering the insert embedment.

This Technical Report does not cover:

• the design of the lifting inserts independently placed on the market;
• lifting inserts for permanent and repeated use.

This Technical Report is prepared based on the fact that the anchorage in the concrete of parts of thelifting assembly is governed by the Construction Products Regulation. Lifting accessories independentlyplaced on the market are governed by the Machinery Directive.

Types of inserts for lifting and handling

This Technical Report applies to the embedment of lifting inserts. Devices made by the precaster mayconsist of smooth bars, prestressing strands, steel plates with anchorage or steel wire ropes. Thesystem devices may be e.g. internal threaded inserts, flat steel inserts and headed inserts.

Lifting loops of ribbed bars are not covered.

Minimum dimensions

This Technical Report applies in general to inserts with a minimum nominal diameter of 6 mm or thecorresponding cross section. In general, the minimum anchorage depth should be hef = 40 mm.

Wire ropes of diameter less than 6 mm are not covered.
