Application load capacityActual break loads (lbs) are quoted, as a guide only, for cablegrips. Application load is normally calculated to be reduced by at least a factor of 5x the actual break load. Due to the wide variety of application parameters, the end-user must apply a sensible safety factor to suit the safety requirements for the conditions of use. Pulling applicationsWhen the correct cablegrip is selected, cable installation through ducts, conduits and trenches is considerably easier. The cablegrip adds little to the overall diameter of the cable and "free passage" is normally available through sheave blocks and pipes. Cablegrips can often be used on a "new for old" cable replacement by applying two grips on a back-to-back basis with a solid link or swivel between grips. This method uses the old cable to pull through the new replacement. Swivel links can be used to allow for reduced torque build-up induced by the pulling equipment and inherent lay in the cables. Lace up cablegrips can be applied anywhere along the cable length, preventing overloading of the cable. Supporting applicationsCablegrips used for cable support applications have the same construction as grips used in pulling applications, except the grips stay in place to reduce strain load. They can be a single- or double-weave type according to the load to be supported and can have one or two supporting ‘eyes’ depending on the available anchor points and the disposition of the load. For supporting cablegrips choose from the various types illustrated in the catalog, including lace-up types, where needed. Due to the constant load-bearing nature of a supporting application, allow for a suitable "factor of safety" on capacity and arrange for regular recorded inspection of the cablegrip’s "condition of safety" throughout its active life. WarningPlease note: Slingco cable socks and grips must not to be used as primary lifting devices. |
