Levelling the truck crane
•
Retract the supporting cylinders evenly. Lower the truck crane only to the
extent that the suspension struts still have enough play for alignment.
•
Level the truck crane with the outriggers until the lamp (1) is the only one
illuminated in the measuring range 1°.
Switching off the suspension
•
Switch off the suspension – the symbol must be red;
suspension on/off , p. 5 - 16.
To secure the truck crane
•
Retract the outrigger cylinders until the outrigger pads are about 5 to
10 cm (2 to 4 in) above the ground. Leave the outrigger beams extended.
Danger of overturning if outriggers are retracted
Always leave the outrigger beams extended and the outrigger pads just
above the ground to secure the truck crane against overturning.
