1. User Manual User manual for assembly use storage and maintenance of pewag winner pro chain slings General The pewag winner pro chain system can be used in a wide range of applications These applications must be checked for suitabi lity by a competent authorized person or by pewag itself in the event of doubt One major application field of the pewag winner pro chain syst m is everhead lifting The following information was prepared forthisgarea in acc with EN 818 6 The specifica tions for assembling chainslings and rating of the capacity only refer to the uniform load method with angle ranges of 0 45 and 45 60 In addition there is also an alternative method of rating the ca pacity This method should only be use d where weight and dis tribution of the load and the angles of the sling legs are known In such cases please contact our technical department as the information given in this catalogue does not inglude details for chain sling rating using this alternative rating method pewag winner pro lifting chains may only be assembled tested and used by competent authorized people If used properly pewag winner pro lifting chains have a long Ser vice life and provide a high level of safety Personal injury and damage to property can however only be prevented by proper use It is therefore very important that you read and understand this user manual and act in a responsible and forward thinking manner when2.
