Towing - use chains rated for safe handling of the shipping splits. Consult the chain manufacturer or
local code requirements for proper safety factors. Attach the chains to the holes at each end of the
shipping base. Secure chains to the towing equipment. Make sure that the floor height is consistent
or provide heavy duty steel sheets to bridge any inconsistencies. Protect the lower edge of the
switchgear from damage by the chains.
Crane - using a spreader bar and either chains or slings connected to the shipping channel extensions,
part no. 921309T01 (provided upon request), lift carefully taking into account the center of gravity.
Once located, final positioning can be done with a forklift. When using either chains or wire rope
slings, place a wooden 4" × 4" block between the equipment and the sling to protect the equipment
from damage.
Jacks and Rollers - raise the units with jacks located at the corners of the shipping bases and move
on steel pipe rollers with the shipping bases attached
CAUTION
Use of forklift trucks for jacking or placing the jacks other than as described may result in stress
distortions and irreparable damage to the equipment.
Do not remove the shipping bases until the units are set in place. Moving the units without the shipping
base will cause irreparable damage and a hazardous condition.
Removal of the Shipping Base
Once the units are in their final place, the shipping bases can be removed.
Open the equipment doors. Remove the bolts holding each of the three shipping bases to the
equipment. If circuit breakers were installed for shipment, the lower position breakers will need to
be removed prior to this step.
Close and secure all doors and panels. Raise the units to a height that allows removal of the base. Use
four jacks located at each corner of the shipping split, just inside of the shipping bases for this
operation. Keep the units uniformly level to prevent distortion.
Select four pieces of wood thick enough to permit removal of the jack after lowering. Place one under
each corner. Slowly lower one side until it rests on the pieces of wood. Repeat this process on the
other side.
Use a pry-bar to lift each corner enough to remove the four pieces of wood.
