Danger of overturning if the outrigger beams are not correctly extended
Extend the outrigger beams only as far as the permissible spans.
Always extend all outriggers to the outrigger spans specified in the
lifting
capacity table
for the planned application.
Even when you are only working on one side. Otherwise the rear stability
for the rigging mode according to the displayed rigging mode is no longer
guaranteed.

Risk of accidents from incorrect or missing markings
Replace missing and illegible markings. First query
Manitowoc Crane Care
for the correct position.
This way you prevent the truck crane overturning due to an incorrect
outrigger span.
