Selecting Operational Status

Warning

Should the operational status be incorrectly registered, the crane might overturn or be damaged, leading to a serious accident. Prior to every operation, check that the registered status corresponds to the actual status of the crane.

Selecting Outrigger and Counterweight Status

Before turning on the load moment indicator, make sure that the switches below are in the following positions:

• In carrier driver’s cab: Key-actuated switch “chassis-superstructure” “1” Rocker switch “PTO” ...........................................“ON”

• In crane operator’s cab: Starter switch......................................................“ON” All of the switches above must satisfy the above conditions to turn on the power supply.

◆ The “on-rubber stationary” status is the default status and is automatically selected when the power supply is turned on. (The outrigger state indicative symbols and front jack symbol remain off.)

◆ Turning the power off automatically erases all the previous settings stored in memory. To resume the operation, enter the settings all over again. Register the outrigger state using the outrigger mode select key and the register key.

When the outrigger mode select key is pressed, the outrigger state indicative symbol, front jack symbol and counterweight state indicative symbol flash in accordance with the status that the AML detects on. After making sure that the display conforms to the actual crane conditions, press the register key. The outrigger state indicative symbol, front jack symbol and counterweight state indicative symbol will change from flashing into being marked up continuously and the moment display, rated lifting capacity display and real load display will return to normal display conditions, meaning that the state has been registered.

◆ If an outrigger or the front jack is stowed after registration of outrigger status, the registered status is erased. In this case, register the outrigger status again before starting crane operation.

◆ Outrigger state indicative symbol is marked up as shown below:

◆ Counterweight state indicative symbol is marked up as shown below:

Selecting Lift Status

◆ The boom lift status is the default status and is automatically selected when the power supply is turned on.

◆ Turning the power off automatically erases all the previous settings stored in memory. To resume the operation, enter the settings all over again.

Register the lift status using the lift mode select key and the register key.

Each time the lift mode select key is pressed, the mode changes in numerical sequence, from (1) to (9). The display returns to (1) if you press the switch while the status (9) is displayed on the screen. Select the status that corresponds to the actual lift status.

◆ After selecting the intended lift status, press the register key to register the status. The corresponding indicative symbols will stop flashing and become marked up and the moment display, rated lifting capacity display and real load display will return to normal display conditions, meaning that the state has been registered. (When the jib set status is selected, the jib lift indicative symbol will remain flashing.)

◆ Select the boom lift status when lifting a load on the boom with the jib mounted.

◆ Select the jib lift status when lifting a single load using both the boom and jib.

Selecting Number of Part-lines of Rope [NOTICE]

◆ If the registered number of part-lines of rope is smaller than the standard number, a maximum allowable lifting load is limited, depending on the registered number. In case the number is registered as ‘0’, however, a process takes place as if the standard number were registered.

◆ Similarly, a process takes place on the basis of the standard number of part-lines of rope if the registered number is larger than the standard number.

◆ When the power supply is turned on, the standard number of part-lines of rope corresponding to a work condition is selected.

Register the number of part-lines of rope using the number of part-lines of rope select key and the register key.

1. Press the number of part-lines of rope select key. The number of part-lines of rope symbol will flash, and the number of part-lines of rope will be shown on the jib angle display in a flashing mode.

2. Press the increase or the decrease key to set the number of part-lines of rope at a desired value.

◆ When the increase or the decrease key is pressed, a numeral showing the number of rope stops flashing and becomes continuously marked up, showing a fixed value for the increase or decrease.

◆ When the increase or the decrease key is kept pressed, the number of rope continuously increases or decreases.

3. Once the intended number of part-lines of rope is set, press the register key and register the number. Then, the number of part-lines of rope symbol will be turned off and the jib angle display will return to a normal status.

◆ The number of part-lines of rope can be confirmed by pressing the display alteration key.
