Section 3—Receiving, Handling, and Storing the MCC 10/2012

ENGLISH
Each shipping block has lifting angles for handling the MCC with overhead
cranes. Take the following precautions when using a crane:
•
Handle MCCs in the upright position only.
•
Select rigging lengths to compensate for any unequal weight
distribution.
•
Do not exceed the 45° maximum angle between the vertical and lifting
cables (see Figure 5).
•
Use only slings with safety hooks or shackles. Do not pass ropes or
cables through the holes in the lifting angle(s).
After the shipping section is in place, its lifting angle(s) may be removed and
discarded. To prevent the entrance of foreign materials, replace all
hardware that secured the lifting angle(s).
Model 6 MCCs with the arc-rated option must have the lifting angle removed
to maintain the arc rating and allow the proper operation of the arc-rated
vent flaps. Retain the hardware from the lifting angle for installing the
top-plate assembly (shipped separately for arc-rated MCCs).
NOTE: Do not attempt to lift or attach lifting means to sections equipped
with pull boxes.
