• first boom down (certain crane types and
cases)
Lifting the load
You obtain the best from your crane in this way:
Ensure that you always have the work in clear
view. If you cannot see the load properly, you
could cause a fatal accident or serious damage.
Sling length
Always attach the load using the shortest possible
sling. The angle between the legs of the sling
must not exceed 120°. The maximum working
load (usually known as the working load limit
(WLL) in standards) of a multilegged sling for
general purposes is calculated by multiplying the
WLL of a single leg by a mode factor, in
accordance with the table.

If the angle between the legs of the sling exceeds
90°, the slings should not be hung directly on the
hook, but rather be slung from a ring that is hung
on the hook.
