GE Industrial Solutions Lift Truck 144D2933G1 - Manual (Page 2)

GE LIFT TRUCK
EACH USER HAS THE RESPONSIBILITY TO
INSTRUCT ALL PERSONNEL ASSOCIATED
WITH THIS EQUIPMENT ON ALL SAFETY
PRECAUTIONS WHICH MUST BE OBSERVED.
GENERAL
GE offers three styles of lift trucks for handling
Power/Vac circuit breakers, ground and test devices
and transformer and fuse rollouts. The first type is a
95” high double-mast truck (144D2933G1) that is com-
patible with indoor switchgear and outdoor non-aisle
switchgear. This truck has 2 fixed front wheels and 2
swivel rear wheels. The lifting winch is located on
the rear of the truck. The second style is a 87” high
double-mast truck (144D2912G1) that is compatible
with outdoor aisle switchgear. This truck has 4 swivel
wheels for easy turning in a confined space and has
the winch located on the right side. The third style is a
79” high single mast truck (144D2911G5) that is re-
quired for special indoor and outdoor applications.
The lift trucks are provided with interlocks to re-
tain the device being handled and to lock the lift truck
to the switchgear while a device is being inserted or
removed. The carriage which lifts a device is raised or
lowered by means of a winch and cable. When the
winch handle is released the carriage is held in that
position by means of a clutch-brake internal to the
winch.
Two arms are attached to the carriage for engag-
ing the track rollers on the sides of each device. The
following procedures describe the necessary steps to
remove a device from, or insert a device into, the
switchgear equipment. Be sure to read and understand
the safety rules identified in this manual before oper-
ating the lift truck.
The lift trucks are functional for both upper and
lower compartments provided the equipment is
mounted on no more than a three inch pad. See Table
2 - Lift Truck Selection (page 11).
NOTE: The figures used in this instruction book depict
the 87” high double-mast lift truck. The operating
instructions apply to all three types
TO REMOVE A DEVICE FROM THE
SWITCHGEAR EQUIPMENT:
NOTE: To remove a breaker or instrument rollout from
an outdoor non-aisle switchgear lineup, first open the
outer door on the unit to the right of the one to be
worked on. Open this door to the fist stop location.
Then open the outer door of the unit to be worked on
to the second stop location. This will allow enough
room to access the right side lift truck track interlock.
1. Prepare the truck for docking with the switchgear
equipment by making sure that both track roller
interlocks (1, Fig. 1) are in the “Transport” posi-
tion (Fig. 2). If they are not, depress the track roller
interlocks and slide the docking interlocks (2, Fig.
1) all the way back toward the lift truck masts.
2. Adjust the height of the carriage until the docking
hooks at the ends of the arms are slightly higher
than the rail surface in the equipment. Position the
hooks over the slots in the rails and lower the
hooks into the slots. Place both track roller inter-
locks (1, Fig. 1) in the “Load/Unload” position (Fig.
3) by depressing them and sliding the docking in-
terlocks (2, Fig. 1) forward, away from the lift truck
masts. The docking interlocks will extend under
the equipment rails and lock the truck arms to the
rails. The track roller interlocks are now in the
raised position so they are no longer blocking the
track rollers. Use the winch to adjust the lift truck’s
arms if they are not approximately level.
3. Release the device from the equipment and roll it
fully onto the lift truck rails until it comes in con-
tact with the stops (3, Fig. 7) on the rails. The
catches that retain a device in the equipment com-
partment are different for the different devices so
see the instructions for the device being handled
for specific information. Verify that the device
rolled freely and that its rollers have properly en-
gaged the rails. Place both track roller interlocks
(1, Fig. 1) in the “Transport” position (Fig. 2) by
depressing them and sliding the docking interlocks
(2, Fig. 1) all the way back toward the lift truck
masts. Raise the carriage slightly to release the
docking hooks from the slots in the equipment rail.
Pull the lift truck back to just clear the equipment
and lower the carriage to, or below, the maximum
transport position (Fig. 4) before transporting the
device to the desired location.
4. To unload the device onto the floor, lower the car-
riage until the device is resting on the floor and
the load of the track rollers is no longer being sup-
ported by the lift truck arms. Place both track roller
interlocks (1, Fig. 1) in the “Load/Unload” posi-
tion (Fig. 3) by depressing them and sliding the
docking interlocks (2, Fig. 1) forward, away from
the lift truck masts. The track roller interlocks are
now in their raised position. The lift truck can now
be pulled away from the device while holding the
backup track roller interlock handle (4, Fig. 1) in
the released position, away from the lift truck
masts.
