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 7.17).
Figure 7.17 – Bottom of Main Boom at Tip End
There is a wire rope connection on the top of the base
end of the main boom (refer to Figure 7.18).
Figure 7.18 – Base End of Main Boom
Visually inspect the whiffle to ensure that it is parallel to
the edge of the boom. The wire ropes run through the
whiffle. Also inspect the Belleville washers. They should
be collapsed with no gaps between any washer.
Also inspect the wire ropes just inside the base end of
the main boom (refer to Figure 7.16).
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 7.19).
Figure 7.19 – Rotation Bearing Bolts
Inspect the rotation bearing bolts to ensure that none are
missing, damaged, or loose.
Upper Control Station
Inspect the platform and upper controls only if all func-
tions operated properly from the lower controls.
Guardrail System
The guardrail system (refer to Figure 7.20) includes the
top rail, mid rail, toeboards and a gravity gate or optional
swinging gate.
Figure 7.20 – Guardrail System
Inspect all components of the guardrail system. The rails
and toeboards must all be in place and free of any dam-
age or deformation. Visually check the rail and toeboard
welds for cracks. All bolts and nuts fastening the plat-
form in place must be present and not show any signs of
looseness.
