Produced in capacities from 20 to 500 tonnes. The shackle body Is manufactured of galvanised alloy steel. The shackle pin (nickel steel up to 35 tonnes, Alloy steel on larger capacities) is retained in the shackle body by means of a nut and split pin, and an anti-rotation device is incorporated in the pin to ensure correct alignment. The pin itself is through bored and strain gauges are internally resin bonded at both shear planes. A close fitting tapered steel bobbin is included to ensure that the load is applied through the midline of the shackle pin. Load cell shackles are available in both cabled (SWLS) and radio telemetry (SWLST) versions. Up to 50 tonnes capacity accuracy is better than 0.5% F.S. over 50 tonnes accuracy is better that 1.0% F.S.
