shows
a
method
of
using jacks
on
outdoor
switchgear
to
facilitate
the
use
of
rollers
under
the
shipping
skid
.
Care
must
be used
with
this method
to
prevent
damage
to

-
Clad
outdoor
equipment
is
shown
in
Figure

.
The load
angles
(
from
horizontal
)
on
the
lifting
cables
,
as
viewed
from
the
front
or rear
,
must
be
at
least
45
degrees
.
A
lesser
angle
could
damage
the
equipment
.
The
lifting
cables
must
have
spreaders
front
-
to
-
back
and
side
-
to
-
side
to
protect
the
equipment
.

longer
than the
depth
of
the
switchgear
,
and should include
adequate
means
to
prevent
the
lifting
cables
from
slipping
off of
the
lifting
pipe
during
use
.
Final
Movement
of
Assembly
Proper
final
movement
and
connection
of
the
assembly
requires
that several items be
completed
:
1
.
Preplan
sequence
of
installation
movements
and connections
.
2
.
Where
equipment
must
be slid into
final
location
,
start
with
the
left
end
shipping
group
and
continue
in
sequence
.
Secondary
conduits which
stub
-
up
above
floor
level
may
block
sliding
.

.
Protect
equipment
and external items
(
e
.
g
.
,
instruments
,
relays
,
etc
.
)
from
damage during
movement
.
Be
sure
to
have smooth
,
unobstructed
surfaces
where the
equipment
is
to
be
slid
.
Keep
access
openings
clear
.
4
.
Prepare
for
the connections
across
shipping
splits
before
the
equipment
is moved into
final
position
.
Interunit bus
supports
and bus
joint
boots should be
removed
using
side
,
rear
and
front
access
options
as
required
.
Note
the
mounting
position
and orientation
and
save
hardware
for
use
in
reinstallation
.
5
.
Thread coiled wires
across
shipping
splits
into
interunit
wire
trough
prior
to
moving
equipment
into its
final
position
.
6
.
Where
top
lift
capability
is available
,
shipping
pallets
and other
packaging
materials
