Rope winch on main boom
If the outer boom with retracted boom system is
overstretched, the rope may rub on the first
extension boom. This may damage the rope
and the extension boom.
In order to prevent this, extend the boom
system before starting rope winch operation
until it no longer protrudes out of the back side
of the outer boom.
Rope deflecting angle
Note!
In order to keep the rope deflecting angle ( D ) as small as possible,
extend at least one extension boom before winch operation (without
fly-jib).
Purpose:
x
This will lead to better rope winding behavior.
x
Small entry angle into rope pulleys.
Warning!
If the rope rubs on other crane components it will get damaged and
may tear. This creates an acute risk of fatality for the operator and
others.
The rope should run smoothly over the pulleys and not rub anywhere.
