•
Comply with applicable national safety regulations.
•
Use legally specified and approved lifting gear.
•
Select the lifting gear based on the prevailing conditions (weather, attachment point,
load, etc.).
•
Only attach the lifting gear to the attachment point. Fix in place with a shackle.
•
Never feed the lifting gear over or through transport lugs without protection.
•
Never feed the lifting gear over sharp edges without protection.
•
Use lifting equipment with sufficient bearing capacity.
•
The stability of the lifting equipment must be ensured during operation.
•
When using lifting equipment, ensure a second person is present to coordinate the pro-
cedure if required (e.g. if the operator's field of vision is blocked).
•
When lifting, make sure that the load limit of the lifting gear is reduced when pulling at an
angle. The safety and efficiency of the lifting gear is best guaranteed when all load-bear-
ing elements are loaded vertically. If necessary, use a lifting arm, to which the lifting gear
can be vertically attached.
•
Ensure the load is lifted vertically!
•
Prevent the suspended load from swinging!
