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 only lamp (1) is illuminated in the
measuring range 1°.
Switching off the suspension
• Switch off the suspension – the symbol must be red;
à Switching the suspension on/off, p. 5 - 16.
To secure the truck crane
• Retract the supporting cylinders until the outrigger pads are about 5 to 10 cm
(2 to 4 in) above the ground. Allow the outrigger beams to extend as far as
possible.
G
Danger of overturning if outriggers are retracted!
Always leave the outrigger beams extended as far as possible and the outrigger
pads just above the ground to secure the truck crane against overturning.
