Chapter 8 Crane operation
181
Load handling close to the crane using rope winch or long lifting gear
x
Lift the load with the extension booms as far as possible retracted (1, 2).
x
Lower the load arm to 60°.
x If necessary extend the hydraulic extension booms.
60°
Max.60°
1 2 3 4
Upper limit range:
Boom system between 60° and 80°:
Caution!
At a boom position higher than 60°
x abrupt crane movements;
x overstretching of outer boom or fly-jib boom
can lead to excessive deflection of the boom system (to side and/or rear).
Consequently the load may fall down. This creates an acute risk of
fatality for the operator and others.
When working above 60°, pay particular attention to the stated load limits.
Increasing the lift angle and height may result in side loading of the boom system. The overload
protection system is unable to monitor this type of loading.
Therefore pay particular attention to
x
working within the range shown in the load capacity chart;
x not overstretching the outer boom and/or fly-jib;
x
smooth crane operation;
Without HPSC working with the boom system above 60° is only allowed when the outrigger beams are
fully extended.
