Perform the Preventive Maintenance Checks and Services (PMCS) identified as
"Before Operation (B)."
NOTE
Prior to operation of the impact hammer, the fuel and lubricating
oil systems must be filled and primed, all lubricating points on the
impact hammer must be serviced, and the waste fuel drip tank
must be drained. The spotter slide is also equipped with
lubrication fittings for servicing. All servicing can be performed by
personnel on the ground.
Pile Gate Installation
The pile gate is connected to the bottom of the lead tower via gibs sliding over the rails on the
front of the foot roller and held in place by a sliding gate stop.
NOTE
If the 18-inch square (concrete) pile adapter is to be used for pile
driving operations, the adapter must be installed prior to installing
the pile gate. Refer to the "18-Inch Square (Concrete) and Sheet
Pile Adapter Installation" Paragraph on Page H-53. If driving
sheet piles the pile gate is not used at all and need not be
installed.
Perform the following procedure to install the pile gate:
a.
Ensure the Load Moment Indicator (LMI) system on the crane is configured for
Front Hoist, Outrigger Position 100%, and Two (2) Parts of Line.
b.
Use the hammer line (main hoist) to lift the impact hammer up the lead tower and
away from the foot roller and use the crane boom to lift the lead tower
approximately two-feet (60 cm) from the ground.
c.
Attach two lifting slings to the five-ton headache ball on the pile line (aux. hoist).
Raise the pile line (aux. hoist) and attach the lifting slings to the pile gate lifting lugs
with 3/4-inch shackles.
d.
Using the pile line (aux. hoist), raise the pile gate and install it on the lead tower by
sliding it beyond the foot roller, aligning the gibs with the rails, and raising. Ensure
that the gibs on the pile gate are fully engaged.
e.
Install the pile gate stop in the foot roller with the stop extended beyond the front of
the lead tower and insert the quick-release pin.
f.
Using the pile line (aux. hoist), lower the pile gate onto the pile gate stop and
remove the lifting slings and 3/4-inch shackles from the pile gate.
g.
Using the hammer line (main hoist), lower the impact hammer down onto the pile
gate.
