Weekly checks of wire rope and
cable
DANGER!
Damaged wire ropes endanger
operational safety!
Therefore examine lifting and safety ropes in ac-
cordance with section 8.2.1 on page 30 for damage
which requires replacement.
Attention!
Lubrication: Keep the wire rope lightly
lubricated. This will not affect the gripping
power but will prolong the life of wire rope to a
maximum.
Check all power supply and control cables and if
necessary replace.
