3. When load factor is "100% or more"
If the hoisted load exceeds 90% (prediction alarm) of the
rated total load and the hoisted load becomes 100% or more
of the rated total load by further continuing crane operations,
the rotating warning lamp changes from the yellow color to
the red color, the alarm sounds continuously and subsequent
crane action stops automatically.
• Hook hoisting action • Boom extending action
• Boom lowering action • Boom hoisting action
In addition, audible warning "Peep, overload" is issued.
4. RECOVERY OPERATION FROM AUTOMATIC STOP
To perform recovery operation from overload, perform either of the following operations so that the
crane action will be opposite to the one when the crane stopped automatically.
Note that the automatic stop cannot be cleared unless the load factor has first been lowered to the
safety area with a load factor of less than 90% (rotating warning lamp: green).
(1) Perform hook lowering operation to put down the hoisted load.
(2) Perform boom retraction operation.
