Before attempting to install the breaker lifting
device assembly on the switchgear equipment, it
is necessary to remove the runner guide from the
breaker lifting device carriage as shown in Fig. 4.27.
Do not dispose of this guide since it must be
reinstalled after mounting the breaker lifting
device on the equipment.
Note: Maximum recommended lifting
capacity is 700 lbs.
Remarque: La capacité de levage maximale
recommandée est de 700
livres (317 kg).
The breaker lifting device should be lifted into
position on top of the switchgear so that the
end with two rollers is toward the rear of the
equipment, Fig. 4.28.
The rear wheels can then be hooked under the
channel and the front wheels can be positioned on
the front track. See Fig. 4.29. The runner guide at
the rear should then be reassembled, Fig. 4.30.
Stop blocks are provided at each end of the front
track to prevent the breaker lifting device from
rolling off the ends of the track.
If the equipment has been shipped in sections,
Fig. 4.32, there are splice plates for the runner
guide and breaker lifting device rail attached to
each respective part.
