[2] MOMENT LIMITER ABNORMALITY OCCURRENCE MESSAGE DISPLAY
The moment limiter displays a fault code on the top screen of the monitor to notify the driver if an
abnormality occurs in the boom angle meter, boom length meter or pressure sensor, or if wiring is
cut or connectors come off.
If a moment limiter related fault code is displayed on the monitor, immediately stop the use of the
crane.
For the fault code and cause and action for the abnormality, see "OPERATION 2.1.2 [2] LIST OF
ERROR CODES".
2.4.3 MOMENT LIMITER OPERATION AND CANCELING (RECOVERY)
The moment limiter is a device that is provided for measures available for an emergency case. In
actuality, any operations relying on the device will incur danger.
Operate the crane carefully so that it does not stop automatically.
[1] PROHIBITED OPERATIONS AFTER AUTOMATIC STOP
The following crane operation is prohibited after the crane stops automatically due to
overload.
Disobeying this rule may cause critical danger due to tipping of the machine or breakage of
the boom, for example.
• Boom lowering operation • Boom hoisting operation • Boom extending operation
• Hook hoisting operation
[2] RECOVERY OPERATION FROM AUTOMATIC STOP
If an automatic stop occurs, you will not be able to clear the stop until you have reduced the
load factor to the safety area with a load factor of less than 90% (rotating warning lamp:
green).
If the moment limiter displays the load factor of 90% or more, be sure to perform crane
operations carefully by turning the engine speed to low.
Performing crane operations at a high engine speed could cause critical danger; in this
case, the hoisted load will waggle resulting in overload, which could lead to tipping of the
machine or breakage of the crane, for example.
1. When load factor is "less than 90%"
When the hoisted load is less than 90% of the rated total load,
the green color of the rotating warning lamp which shows a
normal use condition turns on.
2. When load factor is "90% - less than 100%"
When the hoisted load is 90% (prediction alarm) of the rated
total load, the rotating warning lamp changes from the green
color to the yellow color and the alarm sounds to notify the
driver and persons in the surrounding area that the hoisted
load approaches the rated total load.
