Lift Truck Interlocks
Certain operator actions, if not performed correctly while
operating the lift truck, will cause either the traction motor
or hydraulic functions to become disabled.
DRIVE INTERLOCKS:
The traction motor is enabled when
the operator is in the seat (occupancy sensor), seat belt is
fastened, a direction of travel is selected, and the parking
brake is released.
The battery cover switch, or if lift truck is equipped with a
battery gate switch, must indicate that the batteries are
secure in the battery compartment.
If any of the above actions are not performed while operat-
ing the lift truck, the traction motor will be disabled. The
LCD screen on the display panel will provide a brief text
message to the operator explaining which action is not
being performed and causing the traction motor to be disa-
bled. Examples of this are "Seat Interlock" or "Parking
Brake Interlock." Once the needed action is completed, the
traction motor will be enabled and the operator can con-
tinue to drive the lift truck.
HYDRAULIC INTERLOCKS:
The hydraulic functions are
enabled when the operator is in the seat (occupancy sen-
sor), seat belt is fastened, and the battery cover switch, or
if lift truck is equipped with a battery gate switch, indicates
that the battery is secure in the battery compartment.
If any of the above actions are not performed while operat-
ing the lift truck, the hydraulic functions will be disabled.
The LCD screen on the display panel will provide an icon to
the operator indicating which action needs to be performed
to enable hydraulic functions. Examples of this are "Seat
Interlock" or "Battery Not Secure." See
needed action is completed, the hydraulic function will be
enabled and the operator can continue to load and unload
material.
