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 or other than the values specified for your model.

When the power supply is turned on (i.e. PTO switch ON), the standard number of part-lines of rope corresponding to a work condition is selected.

Register the number of part-lines of rope by use of the number of part-lines of rope select key, as follows:

1. Press the number of part-lines o f 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.

[NOTICE]

When the increase or the decrease key is pressed, a numeral showing the number of rope changes from flashing to being 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 is turned off and the jib angle display returns to a normal status.

[NOTICE]

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