Section 4. Equipment Installation
The rear rollers can then be hooked under the rear runner
and the front rollers can be positioned on the front rail. Refer
to Figure 4.19 and Figure 4.20. The runner guide should be
reassembled to the breaker lifting device using the hardware
retained earlier (Figure 4.19).
WARNING: Failure to install properly or failure to
reinstall the breaker lifting device runner guide may allow
an operator to inadvertantly lift the breaker lifting device
off its rail system and fall unexpectantly.
Stop blocks are provided at each of the front runner to
prevent the breaker lifting device from rolling off the ends of
the rail system.
If the equipment has been shipped in sections, Figure 4.21
and Figure 4.22, there are splice plates for the rear runner
and the front rail attached to each respective part.
NOTICE: Prior to installing the front rail splice plate(s) and
rear runner splice plate(s), the switchgear must be
assembled and achored to its foundation. Failure to follow
this sequence may result in a misalignment of the breaker
lifting device components.
On each shipping split section, remove the bolt holding the
front rail shipping splice plate in place. Retain the front rail
shipping splice plate and remove the front rail shipping splice
plate mounting hardware (Figure 4.21). Install the front rail
shipping splice plate using the mounting hardware. Figure
4.23 depicts a typical front rail shipping splice plate installed.
