45、d maintenance of chain slings A.1 Use of chain slings A.1.1 Chain sling selection A.1.1.1 General The relevant Parts of EN 818 and EN 1677 define working load limit using the term General Lifting Service. This reflects the fact that lifting accessories can be and are used in a wide variety of circum
46、stances in terms of configuration, types of load, methods of attachment. Design considerations and working load limit ratings are given in the relevant Parts of EN 818 and EN 1677 take account of these circumstances. !EN 818-4:1996+A1“ and !EN 818-5:1999+A1“ permit an alternative method of rating wh
47、ere a chain sling is to be used exclusively for a single specific lifting application where all of the circumstances of use are known. A.1.1.2 Use in adverse environments A.1.1.2.1 High and low temperature conditions Care should be taken to take account of the maximum temperature which can be reache
48、d by the chain sling in service. This is difficult in practice but underestimation of the temperature involved should be avoided. Table A.1 summarizes the necessary variation in WLL due to temperature. Chain slings of Grades 4 and 8 will not be adversely affected by temperatures down to -40 C and no
49、 reduction from the working load limit is therefore necessary on this account. Where chain slings are to be used at temperatures below -40 C, the manufacturer should be consulted.
