|Use of wire rope slings|
|Before lifting a load||
|Fitting the Sling||When fitt;ng the sling, it is necessary to ensure that
a) sling legs are free of any tendency to kink;
b) the terminations are properly seated without over-Crowding;
c) the relevant leg angle does not exceed that for which the sling is rated and marked;
d) the sling is not bent around any sharp corners that might damage the sling or reduce its effective strength where necessary/, suitable packing pieces should be used;
1 A sharp corner IS considered to have a radius of curvature of
less than the rope diameter.
2 When a rope is bent over Its own diameter, It can lose 50 % of its original strength.
e) and, when using a choke hitch, to ensure that
1) the angle of choke is allowed to form itself naturally and is not forced,
2) a thimble or stirrup is used, where practicable, at the eye to reduce damage to the rope and thereby prolong the life of both the eye and the main part of the rope;
f) a sling in choke hitch is not used to turn, rotate or drag a load unless special precautions are taken
g) a tag line(s) or control rope(s) is available to assist in the
control of the swing or rotation of the load.
|Raising or lowering the load||
|Precautions||a) no one shall be allowed to ride on the load;
b) a suspended load shall not be left unattended;
c) slings shall not be dragged along the floor;
d) the slings shall not be unnecessarily exposed to corrosive liquids, solids or vapours;
e) if the sling is to be used in an environment where the temperature exceeds 100 OC, advice of the sling manufacturer shall be sought.
