The rated sling capacity needed is then 2,308 (1,154x2) pounds in basket capacity to safely lift the 2,000 pound load. To find out the increase on the load, take the length of the sling and divide it by the height of the upper pick point when the sling is at tension. Multiply the load factor times the minimum weight to be supported by the leg, i.e. Examples include the lifting of persons and lifting of potentially dangerous loads such as molten metals, corrosive materials or fissile material and certain offshore activities. The load factor for 60 from the load factor chart is 1.154. Select the proper bottom fitting: Master Link (O), Sling Hook (S). 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. Determine the proper angle between the leg of the sling and the load during operation. A sling accidentally exposed to temperatures in excess of the maximum permissible should be withdrawn from service immediately and returned to Certex for thorough examination.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. How to determine Sling Load and Angles Take the total weight of the load and divide this by the number of legs supporting the load. 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.
