e.
Using the pile line (aux. hoist), raise the pair of sheet piles into position next to the
initial set of sheet piles (already driven).
f.
Interlock the hoisted pair of sheet piles with the pair already in the ground and
using the pile line (aux. hoist), lower the pair of sheet piles to the ground. The pile
may penetrate the ground under the weight of the piles.
g.
With the pairs of sheet piles locked and secured (and resting on the ground), pull
the rope tag lines to free the ground-release shackles from the lifting holes in the
sheet piles.
h.
Visually inspect the sheet piles to be driven and the bottom of the sheet pile
adapter to ensure that they will mate (with the cleats on the bottom).
i.
Using the hammer (main hoist) line, lower the impact hammer and sheet pile
adapter onto top-center of the sheet piles to be driven. Ensure the top edge of the
sheets fit in between the cleats. The weight of the impact hammer should be fully
resting on the pile.
j.
Using a carpenter's level, ensure the pile is plumb. Raise, lower, telescope the
boom, and/or adjust the length of the spotter to plumb the sheet piles.
k.
Proceed to the "Startup and Shutdown" Procedure on Page H-62 to start the
impact hammer to drive the sheet piles, start the impact hammer, drive the sheet
piles until they are stable in the upright position (not fully driven), and then stop the
impact hammer.
NOTE
This is a temporary elevation. All piles will be driven to the final
elevation after all pairs of sheet piles are driven to the temporary
elevation.
l.
Repeat this procedure to position and drive the remaining sets of sheet piles
alternating, if possible to the left and to the right of the first set of sheet piles until
the desired number of sheet piles have been driven.
m.
Place the impact hammer over installed sheets and drive them in turn, back and
forth, to the final elevation.
Relocating the Crane While Rigged with Pile Driver System (Refer To Figure H-20.)
The crane can be relocated while rigged with the Pile Driver System by transferring some of the
weight of the lead tower and impact hammer to the rear pintle hook and operating the crane "On
Rubber" and in the "Pick and Carry" mode.
WARNING
This procedure presents several opportunities for pinching body
parts. Use care when configuring the Pile Driver System for
transportation.
Perform the following procedure to relocate the crane while rigged with the Pile Driver System
equipment:
a.
Remove any unnecessary weight from the Pile Driver System and crane.
b.
Ensure the Load Moment Indicator (LMI) system on the crane is configured for
Front Hoist, Outrigger Position 100%, and Two (2) Parts of Line.
