Pile Gate Removal

TM5-3810-307-10

If the remote throttle was installed in the superstructure cab, perform the following procedure to

remove the remote throttle from the superstructure cab:

Disconnect the hydraulic hose from the remote throttle by disconnecting it at the

quick connect fitting near the pressure gauge.

Being careful not to pinch or cut the hydraulic hose in the hole, remove the remote

throttle hydraulic hose from the superstructure cab.

Remove the four self-tapping screws securing the remote throttle to the

superstructure cab and remove the remote throttle and remote throttle bracket.

Pile Gate Removal

If necessary, perform the following procedure to remove the pile gate from the bottom of the

lead tower:

Ensure the Load Moment Indicator (LMI) system on the crane is configured for

Rear Hoist, Outrigger Position 100%, and Two (2) Parts of Line.

Use the hammer line (main hoist) to lift the impact hammer up the lead tower and

away from the pile gate and use the crane boom to lift the lead tower

approximately two-feet (60 cm) from the ground.

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 shackles.

Using the pile line (aux. hoist), raise the pile gate away from the gate stop.

Remove the quick-release pin securing the pile gate stop on the foot roller. Retract

the stop into the foot roller and reinsert the quick-release pin.

Using the pile line (aux. hoist), lower the pile gate and remove it from the lead

tower by lowering, disengaging the gibs from the rails, and sliding it beyond the

foot roller. Move the pile gate away from the immediate work area.

Impact Hammer Removal

Perform the following procedure to remove the impact hammer from the lead tower:

Ensure the Load Moment Indicator (LMI) system on the crane is configured for

Front Hoist, Outrigger Position 100%, and Two (2) Parts of Line.

Set the square (concrete) pile adapter upright and place on wood blocking so that it

is aligned directly underneath the direct drive assembly of the impact hammer.

Using the hammer line (main hoist), slowly lower the impact hammer onto the

square (concrete) pile adapter with the adapter sliding fully into the direct drive

assembly. This will move the piston up into the lower cylinder and ensure that

grease is distributed evenly.

Using the grease gun charged with MIL-G-10924 grease, grease the four lower

cylinder (impact block) lubrication fittings (ten shots per fitting).

Using the hammer line (main hoist), raise the impact hammer away from the

square (concrete) pile adapter. Move the square pile adapter away from the work

area.
