Lead Tower Disassembly
Perform the following procedure to disassemble the lead tower:
NOTE
Use the pile line (aux. hoist) of the crane along with the wire rope
lifting sling and nylon lifting sling to move the lead sections during
disassembly.
a.
Ensure the Load Moment Indicator (LMI) system on the crane is configured for
Rear Hoist, Outrigger Position 100%, and Two (2) Parts of Line.
b.
Remove the bolts securing the impact hammer stop to the top of the lead tower
and remove the impact hammer stop. Store the impact hammer stop and bolts in
the tool box.
c.
Attach a wire rope lifting sling and nylon lifting sling to the lead tower (looped
through the holes in the sides). Using the pile line (aux. hoist), hoist and turn the
assembled lead tower over onto its side.
d.
Loosen the bolts, washers, nuts, and joint retaining blocks securing the lead head
adapter to the top of the lead tower and remove the lead head adapter. Reattach
the joint retaining blocks to the lead tower with bolts, washers, and nuts.
e.
Remove the quick-release pin securing the pile gate stop in the foot roller and
remove the pile gate stop from the foot roller.
f.
Attach a nylon lifting sling to the foot roller and support the weight of the foot roller
with the pile line (aux. hoist). Loosen the assembled bolts, washers, and nuts
securing the retaining blocks to the joints of the lead section and the foot roller.
Using the pile line (aux. hoist), remove the foot roller assembly from the base of the
lead tower. Reattach the joint retaining blocks to the lead section with bolts,
washers, and nuts.
g.
Loosen the assembled bolts, washers, and nuts securing the retaining blocks to
the joints of each lead section. Disassemble each lead section joint. Reattach the
joint retaining blocks with bolts, washers, and nuts to the tethered half of the joint.
STORAGE OF THE PILE DRIVER SYSTEM
General
The Pile Driver System, including the lead tower, spotter, impact hammer, lifting slings, and
other tools required to operate the pile driver system are stowed in the weather-proof
shipping/storage container when placed in long-term storage. The shipping/storage container is
to be loaded in the immediate vicinity of the crane and the work area should be clear of any
obstructions prior to loading the Pile Driver System equipment. It is also very important that
components be loaded in a specific order and in exactly the same locations from which they
were removed.
NOTE
The final arrangement of pile driving system components, ready
for loading into the shipping/storage container, should appear as
shown in Figure H-12. The final arrangement of pile driving
system components, loaded into the shipping/storage container,
should appear as shown in Figure H-21.
