Manual alignment • Check that the prerequisites are met; à p. 12 - 47.
• Extend all supporting cylinders until none of the wheels is touching the
ground.
• Level the truck crane with the supporting cylinders until the lamp (1) is the
only one lighting up in the measuring range 1°;
à p. 12 - 41.
• Only lift the truck crane as far as necessary.
Checks to be performed after levelling
During levelling, the ground may give way and the packing may slip.
• After you have levelled the truck crane, check:
– whether all the wheels are lifted off the ground,
– whether the ground under one of the outrigger pads has given way,
– that the packing is correct for the enlarged load-bearing area.
If slewing is permissible in the current rigging mode:
• Slew the superstructure within the permissible slewing range.
• Perform the specified checks again.
• Check the horizontal alignment on the inclination indicator.
G
Risk of accident due to incorrectly supported truck crane!
Perform the following checks each time you have levelled the truck crane
and correct any misalignments.
Otherwise the truck crane may overturn even when lifting a load allowed
by the RCL.
