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.
Working close to the load
Always try to lift the load with the extension
boom retracted, however not completely. The
crane then has the greatest lifting capacity. Place
the vehicle as close as possible to the load.
Working below ground level
If you have to load or unload below the level of
the ground: keep the first boom angle to about 10
to 30° above the horizontal plane.
Heavy loads
Lift heavy loads with the second boom in the
optimum position in relation to the first boom.
For this, see the load plate on your crane.
