3.9 Swing Sensor Overview
The Swing Sensor measures the angle of the upper structure of the crane relative to its carrier. This
angle is used to select capacity charts and operator swing alarms/working area alarms. If the swing
sensor fails, the computer will be unable to select a valid capacity chart. If this occurs, use the Cancel
Alarm Button to lower the load to the ground.
For fault diagnosis, access the swing sensor by removing the collector cover collector at the cranes
swing center. Refer to Figure 3.10 below.
For swing sensor replacement procedures, consult factory service.
