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 7.8) 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 damage or deformation. Visually check the rail and
toeboard welds for cracks. All bolts and nuts fastening
the platform 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.
Rotation Bearing Bolts
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.
Lanyard Anchors
There are two lanyard anchors below the upper control
panel (refer to Figure 7.8).
Visually inspect the lanyard anchors to make sure they
are in place, are not deformed and are securely fastened
to the platform.

ings, structures, or other obstacles. Make sure all
personnel stand clear of the aerial platform while
