Figure 2-2: Lift Truck
Any housekeeping pad placed under the switchgear, must
be less than 4 in. tall for proper operation of the lift truck.
For maximum safety and ease of use, the lift truck will be
locked to the switchgear when a device is being handled,
either inserted or removed. The lift truck should be used to
carry only SecoVac circuit breakers, roll-out transformer
trays, and fuse rollouts. Using the lift truck for any other
application may result in damage to the carriage or injury
to personnel.
The lift truck requires a winch handle to raise or lower the
carriage, and it will hold its position thanks to a clutch-
break within the winch.
