Before driving the truck crane
Fully retracting all telescopic sections of the main boom after greasing may
result in excess lubricant paste emerging at the collar (1).
• Remove any excess lubricant paste from the collar (1).
This is to prevent any lumps dropping off on to the windscreen and sud-
denly obstructing
the view when driving.
8.11.4 Checking the sheaves
•
Check all the sheaves (1) to (4) on the main
boom head and on the bracket for damage,
wear, mobility and for excessive dirt.
Have damaged, worn, stiff or extremely soiled sheaves replaced by
Manitowoc Crane Care or an authorised GROVE dealer or your repair crew.
