Maintenance manual
GMK5200-1
Exercise particular care when operating the crane. Check that the hook
blocks have room to move freely, especially for two-hook operation.
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 collide during crane operation.
In this way, you avoid damaging the retainers, which can lead to the hook
blocks falling over.
Depending on the manufacturer, there are different maintenance intervals
for the dismantling of the hook blocks. The maintenance-free sheaves are
also greased at this time. Some manufacturers recommend dismantling
every 4 years or after 500 operating hours.
