ROTATING BED LEVEL SENSOR
See Figure 4-1.
The rotating bed level sensor (1) is located inside the rotating
bed beside the swing motor. The sensor measures the angle
of the rotating bed and communicates the information to the
crane’s control system through the IOLC30 control module.
The angles are viewable in the Crane Status Bar of the Main
Display Working Screen.
To adjust the level sensor:
1. Move the crane onto a level surface.
2. Using a smart level, measure the crane’s roll and pitch at
the turntable bearing.
3. Securely fasten the level sensor (1) and the mounting
plate (2) to the bracket (3) with the screws, nuts, and
washers.
4. Loosen the nuts (8) and adjust nuts (7) at location A so
the roll and pitch shown in the main display match the
roll and pitch measured with the smart level.
5. Securely tighten the nuts (8).
