Figure 7.17 – Slide Pads at Tip End of Boom
Use the lower controls to raise the main boom to horizon-
tal. Extend the tip boom about 30 cm (1 ′). Visually in-
spect the slide pads to make sure they are in place and
are not obviously loose.
Inspect the surface where the pads contact the interme-
diate and tip booms. The paint must be in place with no
signs of bare metal.
The extension cylinder support bracket has slide pads
(refer to Figure 7.18) that can be inspected by looking
into the base end of the main boom.
Figure 7.18 – Extension Cylinder Support Bracket
Inspect the surface where the pads contact the main
boom. The paint must be in place with no signs of bare
metal.
Wire Ropes
Visually inspect the wire ropes where they are connected
to the outside of the main boom. There are two wire rope
connections on the bottom of the tip end of the main
boom (refer to Figure 7.19).
Figure 7.19 – Bottom of Main Boom at Tip End
There is a wire rope connection on each side of the base
end of the boom (refer to Figure 7.20).
Figure 7.20 – Base End of Main Boom
Also inspect the wire ropes just inside the base end of
the main boom (refer to Figure 7.18).
Fasteners
Visually inspect all fasteners to see that none are miss-
ing or loose.
Pay particular attention to all of the bolts, nuts, rollpins,
collars, and snap rings that connect the booms and cyl-
inders. They should all be present, tight, and not dam-
aged in any way.
Raise the main boom to access the rotation bearing bolts
in the turntable (refer to Figure 7.21).
