Handling
Adequate equipment for handling the motor control centers such as fork truck, crane,
or rods and pipe rollers must be available. Unit weight should be used as a guide for
determining the type of material handling equipment needed. Weights vary by enclosure
type and depth (see unit weights section 13.4). The following instructions are provided
to avoid injury and equipment damage while moving the motor control centers:
1.
Caution should be exercised when moving heavy equipment.
2.
Verify the capabilities of the moving equipment to handle the weight.
3.
Fork trucks, when available, provide a quick and convenient method of moving
motor control centers.
4.
Lifting angles are provided so that the motor control center can be handled by
an overhead crane. The following precautions should be taken when using a
crane:
a.
Handle in the upright position only.
b.
Select rigging lengths to compensate for any unequal weight distribution.
c.
Do not exceed the 45° maximum between the vertical and lifting cables.
d.
Use only slings with safety hooks or shackles. Do not pass ropes or
cables through the holes in the lifting angle.
5.
Use extreme caution when moving sections with rods or pipe rollers.
There is a tendency for the control center to tilt due to its high center of gravity.
After the shipping section is in place, its lifting angle may be removed and discarded.
If the lifting angle beam is removed, then replace all hardware which was used to secure
the angle. This prevents entrance of foreign matter into the holes.
NOTE:
Do not attempt to attach lifting means to sections provided with pull boxes or to lift
sections provided with pull boxes.
