NOTE: If shipping skids are removed prior to final placement of
equipment, rollers may only be used to move the equipment in
a direction parallel to the front.
NOTE: Si l’emballage d’expédition a été enlevé avant que
l’équipement ne soit rendu à son emplacement final, l’utilisation
de rouleaux pour bouger l’équipement n’est permise qu’en
direction parallèle à l’avant.
6. Carefully lower the gear until it rests on the rollers (Fig. 2-7).
7. While carefully pushing the switchgear to its final site
position, the rollers that are freed from the rear of the
switchgear are then repositioned at the forward end. This
procedure should be continued until the switchgear is in its
final location. See Fig. 2-8.
8. When the switchgear is in its final position, remove all lug
bolts holding the shipping skids to the switchgear line-up.
9. Insert the tines of the forklift at one end of the line-up, raise
slightly, and remove the loose rollers.
10. Lower the end of the gear carefully to the floor.
11. Raise the other end of the line-up slightly and remove the
remaining roller at that end.
Jacks
Jacks may be used in place of forklifts to raise and lower
switchgear.
1. Place a jack under the front and rear corners of one end of
the line-up. Figures 2-9 and 2-10 illustrate the use of jacks
with outdoor equipment.
CAUTION: Do not place jacks in any other location other than
the front and rear corners of the switchgear. Doing so may
result in serious damage to the switchgear equipment.
ATTENTION: Il ne faut pas placer de vérins en aucun endroit
autre que les coins avants et arrières du dispositif de
commutation. L’équipement peut être sérieusement
endommagé si l’on ne respecte pas cette directive.
2. Raise the switchgear evenly and just enough to position a
roller beneath the equipment. Gently lower the switchgear
onto the roller. Repeat the procedure at the opposite end of
the switchgear, raising the gear far enough to place the
appropriate number of rollers under the skids, spacing them
evenly across the width of the line-up. Gently lower the gear
onto the rollers.
3. While carefully pushing the switchgear to its final site
position, the rollers that are freed from the rear of the
switchgear are then repositioned at the forward end. This
procedure should be continued until the switchgear is in its
final location.
4. When the switchgear is in its final position, remove all lag
bolts holding the shipping skids to the switchgear line-up.
5. Place one jack at each corner, front and rear, of the
switchgear. Carefully raise the line-up evenly and remove
the rollers and the shipping skids. Evenly lower the line-up
to the floor and remove the jacks.
