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.
Having them
dismantled
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.
• Ask Manitowoc Crane Care about the maintenance intervals for the hook
blocks supplied with your crane.
• Have the hook blocks dismantled by Manitowoc Crane Care or an author-
ised GROVE dealer or your qualified repair crew.
S
Risk of damage to the hook blocks!
Check the hook block regularly for corrosion and condition. This applies
in
particular if
– work is frequently carried out in a corrosive environment,
– the hook blocks collide during crane operation.
This prevents damage than can lead to falling of the hook block
components.
