11.5 Crane operation with main boom
11.5.1 Checks during crane operation
Horizontal
alignment
During crane operation, the truck crane may tilt if the ground gives way due to
varying loads.
• Check the horizontal alignment of the truck crane during crane operation on the
display (1);
à p. 12 - 43.
Due to deformation of the frame, the horizontal alignment can change by up to 2°
when the superstructure is turned from the 0° or 180° position.
If the truck crane does not return to the horizontal position after being turned back
to the 0° or 180° position, you must immediately determine the cause and elimi-
nate it and, if necessary, realign the crane. Observe the position of the super-
structure when doing so;
à Levelling the truck crane on outriggers horizontally,
p. 12 - 43.
Safe distances During crane operation, always ensure that the truck crane and the load are at a
sufficiently large distance to objects and persons. Pay particular attention to
objects that pose a direct danger (for example, gas containers or scaffolding).
Keep a safe distance away from electrical lines;
à Safe distance from overhead
power lines, p. 12 - 14.

Risk of accidents if the truck crane is not level!
The RCL calculates the working radius from the length and angle of the main
boom. The actual working radius changes and there is a danger of the crane
overturning if the truck crane is not level!
