14 Grade 8 products Applications : Grade 8 lifting fittings offer a lifting capacity matching grade 8 chain. Range : Van Beest offers a wide range of grade 8 items in order to assemble a complete sling from the top master link to the hooks. The range extends from 6 mm to 32 mm (1/4” to 1 1/4”). Design : Grade 8 components supplied by Van Beest are all manufactured from alloy steel and generally drop forged. Most master links, eye and swivel hooks have a flat part to make assembly with the omega link (CO) easier. CSEC swivel hooks are equipped with ball bearings. Other swivels hooks are equipped with needle roller thrust bearings. These components are generally stamped with following markings: manufacturer’s identification symbol EXCEL traceability code e.g. AB, pertaining to a particular batch steel grade 8 CE conformity code CE, Conformité Européen item code e.g. MP chain diameter in mm and/or inch e.g. 13 and/or 1/2” origin FRANCE Finish : The grade 8 components are powder coated yellow or red. Certification : Upon request, all the grade 8 items can be supplied with a works certificate and/or EC Declaration of conformity. Some items can also be supplied with a manufacturer test certificate and/or a 3.1 material certificate. We refer to the detailed product information on the next pages. Instructions for use : In general all grade 8 components should be inspected before use to ensure that : • all markings are legible • all items are free from nicks, gouges, cracks and corrosion • items with the correct Working Load Limit have been selected with respect to the sling design i.e. the load to be lifted, the number of legs in the sling, the top angle etc. For further details, we refer to EN818 norm for chain slings • items may not be heat treated as this may affect their Working Load Limit • never modify, repair or reshape an item by machining, welding, heating or bending as this may affect the Working Load Limit • master links and the other items of the sling are all identifiable as being of the same steel grade • items should be used for straight in line loading only, this in order to avoid bending • items are not distorted or unduly worn It is required that the products are regularly inspected and that the inspection should take place minimally in accordance with the safety standards given in the country of use. This is required because the products in use may be affected by wear, misuse, overloading, etc. with a consequence of deformation and alteration of the material structure. Inspection by a competent person should take place at least every six months and even more frequently when the components are used in severe operating conditions.
