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 unspooled 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.
If the device is equipped with synchronized rope control refer also to ‘SRC Synchronized rope control’,
chapter ‘Safety equipment’.
Ensure there is enough distance (A) between pulley head and lower load block during all winch
operations.
A
Winding up the rope:
Warning!
Injuries can result, if rope is tightened by hand.
x
Never tighten the rope by hand.
x Use a weight when winding up the rope (1).
x Prevent rope kinks (2) and slack rope (3).
If the lower rope layers are rarely or never used, unwind the rope after every 100 working hours and
wind it up again while tightening it.
