4 pewag Continuous Maintenance and fittings must be withdrawn from service if any damage or deformation is noticed. Maximum Tolerance (For all chain and components). ation Dimension Max. Tolerance Maintenance Keep a record on all chain slings. Depending on the use of the slings, they should be inspected regularly in accordance with national regulations (ASME B30.9). Inspection Procedure Each link and each attachment shall be examined individually, taking care to expose inner link surfaces of the chain and attachments. and Master rings HS, HSK, LH, F PS, P, KHS, KLH, KF, KP, XK, KO C, CL, CK, CAR BW d t e d2 and h g e c (same as d2) e angle To be removed whenever dm = d + d2 <= 0.9 d 2-0% -0% +0% -0% > 90 Visual Inspection Check for wear, nicks, cracks, breaks, gouges, stretch, bends, weld splatter, discoloration from excessive heat and throat opening of hooks. Measuring The medium link thickness must not be reduced by more than 0% of the nominal diameter on any part of the chain. The elongation of the chain should not exceed 5% at any point. Pitch (p) stretched due to elongation (overloading) Hook bent open Inspection and testing should be carried out in accordance with national regulations. Lifting is dangerous work only competent persons are allowed Pitch (p) increased due to wear to do. Please keep in mind all the hazards and risks covered in ASTM-A906, ISO 3056, EN 88-6 and other relevant standards. *Red denotes original dimension To be removed whenever a deformation is noticed McLaughlin Hoist & Crane Ph: (636)

5 Identification And Testing Pewag lifting chain and fitings are marked with a batch identification number and the manfaturer s identifcation marking: the number 20 or 2 to indicate Grade 20 Alloy, 00, 0 or V to indicate Grade 00 Alloy, 8 to indicate Grade 80 Alloy and 50 to indicate grade 50 Stainless. All Alloy chains are 00% tested to 2 times the working load values and are furnished with a test certificate to this effect. Every chain sling manufactured by Pewag is supplied with a steel tag and test certificate as shown. Caution do not exceed rated capacities McLaughlin Hoist & Crane Ph: (636)

6 Alloy Slings can be assembled with the XK Shortening Hook SOS SOG SOO SGG SSG SG SSS Standard Assemblies of Pewag slings can be delivered with Connex connecting links and accessories ready fitted, with clevis fittings, or in welded construction. Should you require any chain sling assemblies other than those in this brochure, please send us a sketch of the desired model. The standard tolerance of the length L is chain pitch. DOS DOG DOO TOS TOO TOG QOS QOG QOO Single Basket Double Basket Ordering Data Example of How to Order. Determine the maximum load to be lifted. 2. Determine the type of slings needed (single, double, etc.). 3. Estimate the proper angle between the leg of the sling and the load during operation (see page 7). 4. Select the proper fittings (hooks, master links, etc.). 5. Determine the overall reach (measured from bearing point on master link to bearing point of fitting). 6. Choose chain size which meets your required work load, angle and reduction (see page 7). 7. Choose grade, type and finish of steel which meets your requirements. McLaughlin Hoist & Crane Ph: (636)
