Boom Extension Sensors
The front and rear boom extension mounting brackets
feature the following sensors:

mounting bracket. The rear mounting pin is electrically
actuated from the ODM in the operator cab.

the crane control system when the boom extension fly
section is in the stowed position next to the boom base.
Front Mounting Pin Sensor (7, Figure 5-27)—Sends a
signal to the crane control system when the front boom
extension pin is extended in the front boom extension
mounting bracket. The front mounting pin is electrically
actuated from the ODM in the operator cab. For more
information, see Boom Extension Pin Interlock
Mechanism, page 5-21.
Front Side Sensor (8, Figure 5-27)—Sends a signal to
the crane control system when the boom extension base
section is against the front stowage bracket.
Boom Nose Sensor (5, Figure 5-27)—Sends a signal to
