• 19.6 ft. (6 m) extension insert (20 ft insert) to be used
with the 26 ft insert and any of the folding extensions.
All boom extensions are built specifically for the crane with
which they were sold. Each extension is stamped with the
crane's serial number.
Equipment Damage Hazard!
Operate the crane only with extensions which have the
same serial number as the crane, to prevent malfunctions
and damage to the equipment.
To use extensions on several Grove cranes, the extensions
and cranes must be adjusted. Label all extensions with the
respective crane serial numbers.
Have the adjustment of the boom extension carried out
only by Manitowoc Crane Care.
