If the truck crane is equipped with a houselock, the turntable can be locked
in the entire slewing range. For locking, a pin extends and blocks the slew-
ing gear.
Switching on the
houselock
• Slew the superstructure to the position in which it is to be locked and then
stop the slewing movement.
• Open the Superstructure lock menu (1) if necessary.
Switching off the slewing gear
The slewing gear brake must be engaged
when operating the houselock.
• Press the button (1) once.
The slewing gear will be switched off and the
slewing gear brake applied.
– Symbol (2) is red.
– The lamp (3) lights up.
S
Risk of damage during slewing
Always switch off the slewing gear before you operate the houselock. The
system will be damaged if the superstructure is slewed during the locking
procedure.
