(5) Beware of centrifugal force when slewing
Slewing at high speed with a hoisted load causes centrifugal
force to act on the load which in turn increases the working
radius and can cause an overload with the risk of tip over. If you
stop slewing abruptly, the load will swing uncontrollably
imposing a further overload on the boom. Do not slew rapidly
or stop abruptly as these operations lead to tip over and boom
damage.
These problems are particularly severe at long boom lengths.
(6)
Never slew carelessly
If you carelessly slew from a direction with long outrigger
extension to one with short outrigger extension with a load
suspended, the crane could tip over. Even if no load is
suspended, careless slewing could cause the crane to tip over
under some conditions of boom length, boom angle and
outrigger extension.
Secure the crane's footing and confirm that the actual outrigger
extension widths.
19-2-8 Handling the jib
(0099-0020-1E)
(1)
Follow the correct procedure when mounting or stowing the jib
Before you start to mount or stow the jib, refer to the separate
instruction manual to confirm the correct procedure.
Reconfirm the procedure before you start work.
(2)
Set the working configuration setting of the ACS correctly
according to the actual work to be done.
(3)
In jib operation, the lifting capacity is determined on the basis
of the boom angle, not the working radius.
