If a hydraulically derricked lattice extension is electrically connected, the Derrick lattice extension (1) pre-selection button will become active. The button is pressed once to preselect the Derrick lattice extension function. When the crane control system releases the function, the indicator lamp in the button lights up and the released function can be executed with the buttons on the two-hand operating panel.
Two buttons must always be pressed in order to move the preselected function. There are two possible combinations. Buttons that have been pressed are shown in black in the illustrations:
The lattice extension is lowered or raised as long as the buttons are pressed or until the end position or a switch-off point is reached.
To raise the lattice extension: Press the direction button r and also press the Left/down movement button
To lower the lattice extension: Press the direction button r and also press the Right/up movement button
Horn button
The horn button (1) is used to activate the horn of the superstructure if the hand-held control is connected to the socket on the superstructure.
