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

controlled.

CRANE ELECTRICAL SYSTEM

HIAB material handling crane has overload shutdown and/or tilt warning (unstable) systems.

HIAB material handling cranes have a yellow caution light as fixed operator's station and

an audible warning signal that alerts the operator when an unstable crane condition occurs.

HIAB cranes have an overload shutdown system which senses lift cylinder pressure to

prevent overloading the crane. The system will shut down the crane to prevent hoisting,

boom extension, or boom raising when an overload condition exists. Load lowering and

boom retraction functions will not be affected.

The crane electrical system is supplied with power by the vehicle 24 VDC system.

The HIAB 8108-2CD incorporates five separate boxes instead of one junction box (as with

8101 and 8108-2 models). Refer to HIAB crane rear controls and indicators for more

information.

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.
