Permissible attachment and inclination angles
The lifting capacity (e. g. 100 %) corresponds to the
lifting capacity of the clamp. Watch out for stronger
forces in the lifting device caused by pulling at an angle.

When using multiple slings, the permissible load
depends on the suspension angles in each case
(picture 1 and chart 1).

Chart 1
Slings with reeved ropes are no admissible.
To ensure all slings are evenly loaded, a compensating
rocker may be necessary in case of a four-sling
suspension, depending on the load.
In all sling suspension applications, the attachment
points of the individual slings must be above the load
centre of gravity.
