Polar shackles can be used till -60°C.
The rating of shackles to EN 13889 assumes the absence of exceptionally hazardous conditions.
Exceptionally hazardous conditions include offshore activities, the lifting of persons and the lifting of
potentially dangerous loads such as molten metals, corrosive materials or fissile materials. In such cases a
competent person should assess the degree of hazard and the safe working load should be reduced
accordingly from the Working Load Limit.
6. Inspection
It is required that the shackles are regularly inspected and that the inspection should take place 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 should take place at least every six months and even more frequently when
the shackles are used in severe operating conditions.
Shackles should be inspected to ensure that:
•all markings are legible;
•the body and pin are both identifiable as being of the same size, type and make;
•the threads of the pin and the body are undamaged;
•for a safety bolt type shackle is used with the split cotter pin;
•the body and the pin are not distorted or unduly worn;
•the body and pin are free from nicks, gouges, cracks and corrosion;
•shackles are not heat treated as this may affect their Working Load Limit;
•the shackle is not modified, repaired or reshaped by welding, heating, machining or bending as this
will affect the Working Load Limit;
Remove the shackle from service if:
•all markings are not clearly legible;
•body and pin can not be identified as being from same size, type and make;
•the threads of the pin and/or body are damaged;
•for a safety bolt type shackle the split cotter pin is missing;
•the body and/or pin is distorted or unduly worn, the maximum allowable wear is 10% of the original
dimension;
•the body and/or pin is not free from nicks, gouges, cracks or corrosion;
•the shackle has been exposed to any heat treatment;
•the shackle is modified, repaired or reshaped by welding, heating, machining or bending;
•t is expected that before the next periodical inspection any of the inspection criteria above will not be
passed;
