Proper Sling Termination

The slings described herein are "suspension slings" and are different from "lifting slings" as defined by government regulatory bodies. Do NOT use hardware chain. The JBL SoundFactor Install loudspeakers must be used in static suspension applications only. Wire rope suspension slings are suggested for all installations requiring suspension of the JBL SoundFactor Install loudspeakers. The suggested wire rope is identified as 1/8" 7 x 19 Galvanized Aircraft Cable (1/8- 7 x 19 GAC). The minimum working load limit (WLL) of this type of wire rope is 400 lb / 181 kg when terminated properly. If sling lengths are pre-deter- mined and the wire rope slings are fabricated at a rigging supplier, the suggested termination is identified as "swaged Flemish eye terminations with heavy thimbles and certification tags." If sling lengths cannot be predetermined and slings must be fabricated on site, the suggested termination is identified as either a load rated "compression sleeve" or a forged "wire rope clip". Compression sleeves, such as the Nicopress devices, require a specialized compression tool and associated check gauge. Wire rope clips require an end-wrench, socket wrench, and/or adjustable wrench (spanner). The following table defines the load rating adjustments associated with each termination type if the terminations are made accord- ing to manufacturer's instructions:
