KK Lifting Keys are used to attach the crane hook, lifting slings or chains to the KK Lifting Insert, which is cast into the concrete element. KK Lifting Keys enable element lifting, turning and tilt-up. KK Lifting Keys can be used with all of the KK Lifting Inserts without limitation.
KK Lifting Inserts are cast into concrete elements and they act as counterparts for KK Lifting Keys. KK Long Inserts are ideal for all types of lifting operation and are commonly used in thin or very thin elements with sufficient anchoring depth.
