Extend/retract extension booms in winch operation
Danger!
When extending the extension booms and / or unfolding the
outer boom, the rope is tightened. If the unwound rope is too short the
lower load block will be pulled to the pulley head at full force (two-
blocking).
In case of rope winches without overload protection system:
Rope may break if not un-spooled enough. This may lead to
unexpected rope failure and falling down loads.
In case of rope winches with overload protection system:
The rope winch components are protected, but this working position
must generally be avoided.
Ensure there is enough distance (A) between pulley head and lower load block during all winch
operations.
