When using Kuplex slings in exceptional hazardous conditions, the degree of hazard should be assessed by a competent person and the working load limit adjusted accordingly. A sling accidentally exposed to temperatures in excess of the maximum permissible should be withdrawn from service immediately and returned to Certex for thorough examination. The use of KUPLEX chain slings within the permissible temperature range in the table shown does not require any permanent reduction in working load limit when the chain sling is returned to normal temperatures. KUPLEX slings may be used in temperatures down to -40☌ with no reduction in the working load limit. Each of these processes can have dangerous effects and will invalidate the manufacturers certificate. KUPLEX slings must not be heat treated, galvanised, plated, coated or subject to any process involving heating or pickling. Limitations on use Due to risk of embrittlement, KUPLEX slings should not be used in acid or caustic solutions nor in heavily acidic or caustic laden atmospheres. If the sling angles are on or inside the guidelines the sling is within the angle rangeĠ˚<ß « 45˚, as specified in the load chart. No chain sling should be used if the angle from the vertical exceeds 60˚, as beyond this point the forces in the legs drastically increase.ĭO NOT USE MULTI-LEG CHAIN SLINGS AT ANGLES WITHIN THE SHADED AREA (as seen in the diagram above).Īngles of less than 15˚ should also be avoided as these can lead to the load becoming unstable. Chain Slings restrictions on the angle of use - Variation of chain sling leg loading with leg angle for a load of 10t.Īll multi-leg chain slings exert a horizontal component of force, which increases as the angle from the vertical becomes greater.
