3.1.2 Rope maintenance
VISUALLY INSPECT YOUR ROPE BEFORE EACH USAGE. IF IT
SHOWS ANY SIGN OF DETERIORATION (CUT STRANDS, EXCESSIVE ABRASION)
REPLACE IT.
IF YOUR ROPE IS DIRTY, WASH IT. DIRTY ROPES DETERIORATE
FASTER AND CAUSE PREMATURE WEAR ON PARTS WHICH ARE IN CONTACT WITH
THE ROPE.
3.2 At the end of the rope
3.2.1 Recommended knots
You have to attach the load to the end of the rope. Even if
a simple knot can do the job, we recommend the
installation of a hook with the bowline knot (figure 1 on the
right) because it can be easily undone if you need to
change the hook. Moreover, it retains about 70% of the
rope’s capacity while most knots will reduce it by more
than 50%.
Even better, the double bowline knot (figure 2) will keep
about 75%
of your rope’s capacity.
3.2.2 Recommended hooks
If you usually pull with a choker chain,
use a grab hook (figure 1) or grab
hook with latch (figure 2). If you
usually pull a sling or a ring, use a
safety hook with latch (figure 3) or
shackle (figure 4).
