RR Long Inserts are used in applications where sufficient anchoring depth is available. RR Long Inserts are ideal for all types of lifting operations.
RR Long Inserts are suitable for thin or very thin wall and beam elements with sufficient anchoring depth. RR Lifting Inserts are permanently anchored into the precast element, and they are used with RR Lifting Keys. RR Lifting Inserts are cast into concrete elements to enable the elements to be lifted after the concrete has hardened.
RR Long Inserts are CE-marked and follow the standards of the Machinery Directive (2006/42/EC). The inserts are available in black steel as standard, but they are also available in galvanized form upon request. The minimum compressive strength of the concrete upon load application is 15 MPa.
RR Lifting Keys are used to attach a crane hook, lifting slings or chains to an RR Lifting Insert which is cast into the concrete element. RR Lifting Keys are suitable for all lifting operations and directions and can be used with all RR Long and Short Inserts.
