determining whether the mobile unit meets the
stability requirements.”
With the truck on fi rm level ground, the lower boom
fully raised, the upper boom horizontal, and the
inner boom extended rotate to the front or rear
and suspend the appropriate weight from the
platform. Rotate the lift to the side, add ballast to
the truck frame if required to achieve stability. The
placement of any ballast will affect the stability and
the fi nal weight distribution and must be evaluated.
“4.5.2 Stability On Slopes - Each aerial
device, when mounted on a vehicle meeting the
manufacturer’s minimum vehicle specifi cations
without readily removable tools and material and
used in a specifi c confi guration shall comprise a
mobile unit capable of sustaining a static load one
and one-third times its rated load capacity in every
position in which the load can be placed within the
defi nition of the specifi c confi guration when the
vehicle is on a slope of 5 degrees in the direction
of least stability.
The load shall be applied at one and one-third
times the platform capacity at the center of the
platform, simultaneously with one and one-third
times the lifting attachment supplemental capacity
in its position of maximum overturning moment
when so equipped. If having outriggers or other
stabilizing components utilized is part of the
defi nition of the confi guration, they shall be utilized
according to the manufacturer’s instructions for the
purposes of determining whether the mobile unit
meets the stability requirements.
Simultaneous application of platform capacity and
supplemental capacity shall be performed only on
the aerial devices that are designed for use with
both types of load applied simultaneously.”
With the lower boom fully raised, the upper boom
horizontal, and the inner boom extended rotate the
lift to the front or rear and suspend the appropriate
weight from the platform. Rotate the lift to the
downhill side of the vehicle, add ballast to the
truck frame, if required to achieve stability. The
placement of any ballast will affect the stability as
well as the fi nal weight distribution and must be
evaluated in these respects.
“4.5.3 Effects of Stability Test - None of the
stability tests described in 4.5.1 and 4.5.2 shall
produce instability of the mobile unit or cause
permanent deformation of any component.
Note: During the stability test, the lifting of a
accordance with requirements of 6.6.1 and 6.6.2,
and the appropriate electrical tests required in
5.4.3 of this standard.”
Section 6.6 Mechanical Tests and Inspection
reads as follows:
“6.6.1 Operational Tests - In addition to the
manufacturer ’s prototype tests and quality
assurance measures, each aerial device, including
mechanisms, shall be tested by the manufacturer
to the extent necessary to ensure compliance with
the operational requirements of this section.
Some examples are:
1) Boom(s) elevating and lowering mechanism
2) Boom extension mechanism
3) Rotating
mechanism
4) Stability tests
5) Safety devices. Each aerial device shall be
operated to verify the function of all safety
devices.
When the mobile unit is not completed by the
manufacturer, such tests, which can be performed
only after complete assembly and installation, shall
be the responsibility of the fi nal installer.”
Section 4.5 Stability reads as follows:
“4.5.1 Stability On Level Surfaces - Each aerial
device, when mounted on a vehicle meeting the
manufacturer’s minimum vehicle specifi cations,
without readily removable tools and material and
used in a specifi c confi guration, shall comprise a
mobile unit capable of sustaining a static load one
and one-half times its rated load capacity, in every
position in which the load can be placed within the
defi nition of the specifi c confi guration, when the
vehicle is on a fi rm and level surface.
The load shall be applied at one and one-half
times the platform(s) capacity at the center of the
platform simultaneously with one and one-half
times the lifting attachment supplemental capacity
in its position of maximum overturning moment
when so equipped.
Simultaneous application of platform capacity and
supplemental capacity shall be performed only on
the aerial devices that are designed for use with
both types of load applied simultaneously.
If having outriggers or other stabilizing components
utilized is part of the defi nition of the confi guration,
they shall be so utilized according to the
manufacturer’s instructions for the purposes of
