Information on
crane operation
Exercise particular care when operating the crane. Check that the hook
blocks have room to move freely, especially for two-hook operation.
G
Risk of accident due to falling ballast plates.
Always secure the ballast plates with the pins and the securing plugs.
Always check the completeness and condition of the securing plugs before
operating the crane. This prevents ballast plates from falling down during
crane operation.
S
Risk of damage to the hook blocks.
Check the retainers for the ballast plates regularly for corrosion and condi-
tions. This applies in particular if
– work is frequently carried out in a corrosive environment
– the hook blocks are transported ballasted
– the hook blocks collide during crane operation.
In this way, you avoid damaging the retainers, which can lead to the hook
blocks falling over.
