3.5.8 Lift adjuster
When lifting a load, the boom bends downwards and the working radius increases. In order to en‐
sure that the load remains in the same position after it is lifted, the crane driver must control the
derrick and the winch simultaneously.
The lift adjuster can minimize the extension of the working radius when lifting the load from the
ground using a single joystick movement (only the hoisting gear is lifted).
If the weight of the load to be lifted is less, the effect of the lift adjuster is
low.
Do not use the lift adjuster when the rated load is less than 1.5 t
(3,306.9 lbs) or when the object to be lifted deforms severely or when
the boom head and the bottom block oscillate considerably owing to
wind, etc.
Operating the "lift adjuster"
1. The centre of the bottom block should be above the centre of gravity of the load.
Then increase the tension of the slinging rope slightly.
Setting the correct number of rope falls is extremely important to be able to control the lift ad‐
juster precisely. Ensure that the number of rope falls set in the automatic safe load indicator
matches the actual number.
WARNING! The load may oscillate if the bottom block is not above the centre of gravity of
the load.
WARNING! Do not increase the tension of the slinging rope excessively. Excessive
tension (over 0.2 t (441.0 lbs)) may lead to severe oscillation of the load.
