Remove the Shipping Skids
The equipment is fastened to the shipping skids with ½ inch
lag bolts through the equipment anchoring holes (Figure 4.5).
Equipment shipping sections up to 10 feet long will be
fastened to the skids with four lag screws and/or carriage
bolts, along the front and rear of the assembly. The shipping
skid and screws/bolts are expendable material and may be
disposed of at the purchaser's discretion.
Fasten Sections Together
After placement of the equipment and installing the anchor
bolts loosely, the various shipping sections must be rigidly
fastened together. Through-bolts fasten each section of the
switchgear equipment to the adjacent section. Figure 4.6
shows the location of the through-bolts.
Figure 4.7 illustrates the installation of the through-bolts. The
through-bolts are in the front and rear compartments. The
nut and bolt assembly should be tightened with a torque of
25-30 ft.-lbs.
All of the hardware required for assembling the equipment
across the shipping splits is furnished with the equipment. If a
transformer is included in the lineup of equipment, the
transformer flange should be aligned with the opening in the
side of the transition section and fastened together using the
3/8-16 bolts, nuts and washers supplied with switchgear. The
fastener assembly should be tightened with a torque of 25-30
ft.-lbs.
