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 7.18) includes the
top rail, mid rail, toeboards and a gravity gate or optional
swinging gate.
Figure 7.18 – 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.
Inspect the gravity gate to be sure it is present, is not
damaged, and moves freely.
Inspect the optional swinging gate to see that it swings
freely, closes firmly, and is not deformed in any way. Make
sure the spring closes and secures the gate when the
gate is closed.
Figure 7.15 – Top of Main Boom at Base End
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 7.17).
Inspect the rotation bearing bolts to ensure that none are
missing, damaged, or loose.
