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 to you.
• Have the hook blocks dismantled by Manitowoc Crane Care or an
authorised GROVE dealer or your qualified repair crew.
