CRANE ELECTRICAL SYSTEM - Continued

The junction box on the crane connects and distributes the various control circuits of the

crane. The HIAB 8108-2CD incorporates five separate boxes instead of one junction box.

Tilt warning, outrigger extended warning, and remote control systems are electronically

controlled.

Tilt Warning System

NOTE

Refer to the crane data plate (on passenger side rear fender) to for HIAB

crane model (8108 or 8108-2/8108-2CD).

All crane electrical functions are routed through the crane junction box (1).

When more than 5 degrees tilt is detected on the 8108 crane-equipped vehicle, a signal is

sent causing the buzzer to pulsate on and off and the lamp to glow steadily.

The tilt sending switch for the 8108-2 crane equipped vehicle is set to actuate when more

than 7 degrees tilt is detected.
