6. Reduction of Rated Capacity
Boom Lift
The rated capacities for boom lift assume that the jib is stowed in the specified position and the main winch is
used. When the jib is attached to the boom end during boom lift, subtract the value in the table below from the
rated capacity.
Single Top Lift and Jib Lift
The rated capacities for single top lift or jib lift assume that the main winch is used. If you perform single top lift
or jib lift using the auxiliary winch, subtract the mass of the main hook block from the rated lifting capacity
values.

AML vent / compulsory unload of the main relief valve.
٠If an overload occurs, the AML stops the 24-V output from Do1. Thus the solenoid valve for VENT is
returned to neutral by the spring and vents the oil in the spring side of the balance piston in the main-circuit
safety valve into the tank circuit. The whole oil discharged by the pump is unloaded into the tank, making
crane operation toward critical sides impossible.
٠When crane operation toward non-critical sides (hoisting down, boom raising, boom retraction) is detected,
no oil is vented from the safety valve into the tank. Thus the crane operation becomes available.
:
If operation toward critical sides (hoisting up, boom lowering, boom extension) is attempted while the hook
block is over wound, 24-V output from Do1 stops. Thus the crane operation toward critical sides becomes
impossible due to AML vent (compulsory unload) in the same way as overload.
When operation toward non-critical sides is detected, the operation becomes available.
When the boom is raised over the specified angle, the output from Do1 stops and the crane operation stops
automatically due to AML vent. Recovery from the automatic stop is possible only by boom raising.
When the boom head approaches a pre-registered limit of the working range, slow stop function works and
the AML energizes the corresponding proportional solenoid valve. It slowly closes the pilot pressure circuit
for the main control valve to decelerate crane operation until the main control valve becomes neutral and
the output from Do1 stops to make AML vent disable crane operation. For swing limit, however, the
proportional solenoid valve makes the main control valve immediately to stop the crane. In this case the
crane does not swing beyond the limit even if the AML override is activated, and it swings only toward within
of the limit.

1.1.2 AML-C Block diagram
1. While the PTO switch is ON, AML-C and DCU give and take the data on the version No. of the DCU and error
occurring in the DCU.
For details of the data, refer to the "N-1 DCU" section in the service manual for the corresponding model.
2. The signal transmitter (STM-E) is common to all GR model.
For details of the data, refer to the "N-1 STM-E" section in the service manual for the corresponding model.
3. Communication between STM-E and ECU on the machine with Mitsubishi engine (GR-750XL-2,
GR-1000XL-2) is sent via K-LINE.

• Load moment ratio is not a ratio of the
hoist medium load to the rated capacity.
Find the correct hoist medium load from
the rated capacity.
• The AML is not a hoist medium load
indicator. The hoist medium load
indication is a reference value, and not a
correct mass of the lifted load.
