An apparatus and method for rigging a sling between a load to be lifted and a lifting machine such as a crane. The sling rigging apparatus includes first and second plates which have a plurality of aligned apertures. A shaft is fixed between the plates and is attachable to a crane hook to allow the rigging apparatus to be raised. A plurality of sling engageable pins are insertable in a longitudinal direction through the aligned apertures to positions spanning a space between the plates. When inserted through the apertures, the pins are spaced from each other in a direction transverse to the longitudinal direction and arranged to define a multi-curved pathway. A sling positioned along this pathway contacts parts of the exterior peripheries of the plurality of pins, and when a load is applied on the sling, this contact with the pins causes the sling to be frictionally locked within the rigging apparatus.
