1b) To Move 6 through 9-Bay
System Assembled
1. Unfasten all post caps, inspect for damage and
set aside for next installation.
2. Attach a four point sling to each plate. Place sling
through the lifting loops located on each corner
of the plates, see Figure 57.
3. Free the system from anchor posts prior to lift-
ing. To accomplish this, start at the nose of the
system and use pry bars to gradually raise the
system off of the studs. Place blocks such as
2x4's under the anchor plates and work down
the length of the system until the system is com-
pletely free.
4. Attach slings to a multiple spread lifting bar/beam
and adjust sling positions as needed in order to
balance the system.
5. Lift the system to new location.
6. Extract the Drivable Pile Anchors (see next steps).
7. Replace all damaged parts.
8. Re-install system.

2) Extracting Drivable Pile Anchors
1. Fasten a ¾" threaded lifting ring or eye into a
hole at the top of the post.
2. Attach a hoist or crane to the ring and pull the
post from the ground.
3. Remove posts as necessary and backfill holes
created by the extraction.
WARNING!
The posts will be filled with soil and extremely
heavy. Handle with caution.
3) DPA Refurbishment
Remove all soil and other material from inside of the
post being careful not to damage the side walls of
the tubing. The bottoms of the posts may be dam-
aged from initial pile driving. Cut the damaged por-
tion of tubing from the post so that side walls are
straight for the next installation. If the side walls of
the post are damaged at more than 12" from the bot-
tom of the post, scrap the post and replace it with a
new one.
