Ensure there are no visible cracks in -
welds or structure and there are no signs
of deformation.
Wheel/Tire Assembly•
The aerial platform is either equipped with
air tires or foam-filled tires. Tire and/or wheel
failure could result in an aerial platform
tipover. Component damage may also result
if problems are not discovered and repaired
in a timely fashion.
WARNING
An over-inflated tire can explode and
may cause death or serious injury.
Check all tire treads and sidewalls for cuts, -
cracks, punctures and unusual wear.
Check each wheel for damage and cracked -
welds.
Check each lug nut for proper torque to -
ensure none are loose.
To safeguard maximum stability, achieve optimum
aerial platform handling and minimize tire wear,
it is essential to maintain proper pressure in all
air-filled tires.
Check each tire with an air pressure gauge
-
and add air as needed.
Refer to Table 2.6 for wheel/tire specifications.
