Remove the slack in the pile line (aux. hoist) to slightly support the spotter.
Pull the rope tag line attached to the manual release on the spotter slide to
disengage the pin from the hole in the lead tower and hold in place. Using the pile
line (aux. hoist), lower the spotter and replace the retainer pin to keep the spotter
slide pin retracted.
Using the pile line (aux. hoist), lower the spotter and using the crane boom, raise
the lead tower to disengage the spotter slide from the lead tower. During this
procedure, the position of the spotter and lead tower will need to be adjusted to
prevent the spotter slide from binding. When fully disengaged from the lead tower,
raise the spotter to a horizontal position using the pile line (aux. hoist).
Instruct the crane operator to fully retract the spotter and then extend it
approximately two inches (5 cm) to the white line painted on the spotter.
Fully retracting the spotter and then extending it approximately
two inches (5 cm) to the white line painted on the spotter will
relieve any pressure built up in the hydraulic lines and make the
spotter the exact size required to fit properly in the
storage/transportation container. The spotter will not fit properly in
the storage/transportation container and the hydraulic lines will be
not be able to be reconnected to the spotter (without relieving the
pressure manually) unless this is performed.
Remove the hydraulic hose reel lines from the hydraulic hose connections (spotter
manifold) on the spotter and replace the protective caps.
Temporarily attach the hydraulic hose reel lines to the spotter mounting bracket
and secure the hoses with a temporary hydraulic hose retainer chain (i.e. small
length of chain). Remove the hydraulic hose retention chain attached to the base
of the spotter from the chain attached to the hydraulic hose reel lines.
Check the pressure at the two spotter support pins securing the
spotter base in the mounting lugs on the spotter mounting
brackets when removing the spotter from the crane. The pins
must move easily before trying to remove them.
Remove the cotter pins from the two spotter support pins.
With ground personnel at each end of the spotter, carefully remove the two spotter
support pins securing the spotter base in the mounting lugs on the spotter
Using the pile line (aux. hoist), hoist and remove the spotter from the spotter
mounting brackets on the crane superstructure. Place the spotter on the ground in
Remove the rope tag line from the hole on the manual release on the spotter slide
and place in the tool box.
