2.5 Shackles
Only those shackles may be used which are in accordance with American Standard
RR−C−271A or which fulfil or exceed these values, including the safety factor.
All calculations for components and tools where shackles are used are laid out
accordingly and based on the mentioned standards.
Normally, the permissible lifting capacity of the shackles is specified for one single
strand.
CAUTION
If tools are combined (e.g. beams with shackles, RUD-eye bolts
or RUD-swivel lugs and ropes, etc.), it is always the weakest ele-
ment which determines the maximum lifting capacity (see details
in Tools List 9403−5).
