Crane operation
186
Caution!
Operating crane functions at full working speed to the cylinder stop:
x
increases the wear of components and reduces the life of
the crane;
x the load may fall down.
This creates an acute risk of fatality for the operator and others.
x
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.
x
Finish crane movements slowly and smoothly by releasing the operating levers carefully.
x 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.
x
If crane functions are used simultaneously (combined crane movements create a different load
path), reduce the speed of the individual functions accordingly.
In case of emergency
In case of emergency stop all crane movements immediately (refer to chapter 5,
'Emergency cut-off
button'
).
Lowering the load
Caution!
In cranes without overload protection system, the load lowers
uncontrollably when the permissible load moment is exceeded.
Refer to 'Paltronic 150 standard safety equipment ' in chapter 5.
Don't increase the outreach when lowering the load.
If you increase the outreach when lowering the load, the load may lower uncontrollably. Monitor the
capacity indicator.
