Chapter 8 Crane operation
Caution!
If controls are unintentionally operated with the load and/or
crane components, there is an acute risk of fatal injury to the operator
and others.
During all crane operations, maintain an adequate distance between the load, crane components and
controls.
Caution!
Abrupt crane movements can make the load swing.
Consequently the load may fall down. This creates an acute risk of
fatality for the operator and others.
Carry out all crane movements smoothly.
•
Grasp the operating lever of the crane function firmly.
•
Press the lever slowly until the crane responds.
•
Monitor the overload capacity indicator (refer to chapter 5, 'Overload display').
•
If the yellow range is reached, reduce the working speed.
•
Lift the load a little and check whether it is correctly attached and stays in the intended position.
Caution!
Operating crane functions at full working speed to the
cylinder stop:
•
increases the wear of components and reduces the life of
the crane;
•
the load may fall down.
This creates an acute risk of fatality for the operator and others.
•
It is prohibited to operate crane functions (with/without load) at full speed to the cylinder stop.
Caution!
Releasing the operating levers suddenly can cause the
load to swing uncontrollably. Consequently the load may fall down.
This creates an acute risk of fatality for the operator and others.
•
Finish crane movements slowly and smoothly by releasing the operating levers carefully.
•
It is possible to operate several crane functions at a time.
This may reduce the speed of the already actuated crane movements.
Warning!
If several crane functions are used at a time and one or
more are stopped, the remaining active function(s) may increase in
speed.
•
If crane functions are used simultaneously (combined crane movements create a different load
path), reduce the speed of the individual functions accordingly.
In the event of sudden danger
In case of an emergency, stop all crane movements immediately (see also 'Emergency cut-off button‘,
chapter 5).
