• JIB tipping check
The JIB can tip in relation to the 2nd boom. When the
JIB goes beyond the alignment with the 2nd boom,
the system emits a double sound, both raising and
lowering the JIB.
When the JIB is in tipping position, if the crane
booms are in the max. verticality position, the system
blocks the lifting movements when the JIB reaches a
50° verticality (Max. verticality allowed under the JIB
position). The displays show the crane movements
blocked.
NOTE
The configuration with the basic crane in completely vertical position is possible
only if the JIB is not in tipping position.
6.1.2. MAX speed limitation (automatic slow-down)
This feature is managed by Progress and keeps the
operation safe and efficient in one or more of the following
conditions.
• Safe operation with the crane in vertical position
(2nd boom over 50º till the max verticality) when:
◦ working with the crane boom system in vertical
position to prevent sudden movements that could
damage the load and the crane.
◦ operating a quick lowering movement starting
from the vertical boom system position (the
load could hit the boom and the descent could
become not easy to control, compromising the
load stability).
◦ operating quick slewing movements with the boom
extensions fully extended in vertical positions.
◦ extending quickly the boom extensions.
◦ having lateral deflection on the boom system over
70º more than 3º.
