Weldments
To inspect the weldments:
1. Visually inspect all weldments for abnormal wear,
abrasion, or deformation that could cause interfer-
ence between moving parts.
2. Inspect the welds on the structural components. Pay
particular attention to arm welds around pin bosses.
The area to be inspected should be clean and free
of dirt and grease.
3. Look for visible cracks in the welds and at the weld
to parent material joints. A bright light may be used
to provide adequate visibility of the inspection area.
Fasteners
To inspect the fasteners:
1. Visually inspect all fasteners to see that none are
missing or loose.
2. Inspect all of the bolts, nuts, rollpins, collars, and
snap rings that connect the elevating assembly. They
should all be present, tight, and not damaged in any
way.
Upper Control Station

operated properly from the lower controls.
Guardrail System
The guardrail system includes (refer to Figure 7.11):
A top rail
A mid rail
An entry gate
Toeboards around the sides of the platform.
Figure 7.11 – Platform
To inspect the guardrail system:
