AMERICAN NATIONAL STANDARD
Approval of an American National Standard requires verification by ANSI that the requirements for
due process, consensus, and other criteria for approval have been met by the standards developer.
Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial
agreement has been reached by directly and materially affected interests. Substantial agreement means
much more than a simple majority, but not necessarily unanimity. Consensus requires that all views
and objections be considered, and that a concerted effort be made toward their resolution.
The use of American National Standards is completely voluntary; their existence does not in any
respect preclude anyone, whether he has approved the standard or not, from manufacturing, marketing,
purchasing, or using products, or procedures not conforming to the standards.
The American National Standards Institute does not develop standards and will in no circumstances
give an interpretation of any American National Standard. Moreover, no person shall have the right or
authority to issue an interpretation of an American National Standard in the name of the American
National Standards Institute. Requests for interpretations should be addressed to the secretariat or
sponsor whose name appears on the title page of this standard.
CAUTION NOTICE: This American National Standard may be revised or withdrawn any time. The
procedures of the American National Standards Institute require that action be taken to reaffirm, revise,
or withdraw this standard no later than five years from the date of approval. Purchasers of American
National Standards may receive current information on all standards by calling or writing the
American National Standards Institute.

FOREWORD
This foreword is not part of American National Standard for Vehicle-Mounted Bridge Inspection and
Maintenance Devices, ANSI/SIA A92.8-2012.
This standard is one of a series on aerial platforms developed under the committee procedures of the
American National Standards Institute. The A92 standards committee was organized by the Institute in
1948. The Scaffold Industry Association, Inc. serves as Secretariat.
The primary objective of this standard is to prevent accidents associated with the use of Mast-Climbing
Work Platforms by establishing requirements for design manufacture, installation, maintenance,
performance, use and training.
Interpretations and Suggestions for Improvement
All inquiries requesting interpretation of the Committee’s approved American National Standards must
be in writing and directed to the Secretariat. The A92 Committee shall approve the interpretation
before submission to the inquirer. No one but the A92 Committee is authorized to provide any
interpretation of this standard.
The A92 Committee solicits comments on and criticism of the requirements of the standards. The
standards will be revised from time to time where necessary or desirable, as demonstrated by the
experience gained from the application of the standards. Proposals for improvement of this standard
will be welcome. Proposals should be as specific as possible, citing the paragraph number(s), the
proposed wording, and a detailed rationale for the proposal including any pertinent documentation.
All requests for interpretation and all suggestions for improvement shall be forwarded in writing
to the ASC A92 Committee, c/o Secretariat ~ Scaffold & Access Industry Association, 400 Admiral
Boulevard, Kansas City, MO 64106
This Standard was processed and approved for submittal to ANSI by Accredited Standards Committee
Aerial Platforms, A92 Aerial Work Platforms. The ASC A92 committee approval of the standard does

American National Standard
For Vehicle-Mounted Bridge Inspection and Maintenance Devices
1 Introduction. Mobile units covered by this standard are
generally designed to be supported on bridge surfaces of
varying degrees of grade and super-elevation and have
the capability of providing personnel quick and easy
access to the underside of such structures.
The rapid development of a wide variety of trailer and
truck-mounted mobile unit designs necessitates the
establishment of standards for their design, manufacture,
remanufacture, installation, performance, inspection,
training, maintenance, testing and use.
Normally, they are not insulated for use near electrically
energized apparatus nor are they intended to be used in
hazardous locations. Any mobile unit intended for use
around energized electrical apparatus shall be designed,
manufactured, and used in accordance with the
requirements outlined in ANSI/SIA A92.2-2009, VehicleMounted Elevating and Rotating Aerial Devices.
The operation of any mobile unit is subject to certain
hazards that can be protected against only by the exercise
of intelligence, care, and common sense and not by
mechanical means. It is essential to have competent,

on the opposite side of the load does not necessarily
indicate a condition of instability.
5.12 Bursting safety factors. All hydraulic components
whose failure could result in motion of the platform(s)
shall have a minimum bursting strength of at least four
times the operating pressure for which the system is
designed. All other hydraulic components normally rated
according to bursting strength, such as hose, tubing, and
fittings, shall have a minimum bursting strength of at
least three times the operating pressure for which the
system is designed. All other hydraulic components
normally rated according to performance criteria, such as
rated flow and pressure, life cycles, pressure drop, rpm,
torque, and speed, shall have a minimum bursting
strength of at least two times the operating pressure for
which the system is designed. Such components
generally include pumps, motors, directional controls, and
similar functional components.

could result in stresses that exceed the yield strength of
the material.
5.13.4 Wire rope/chain systems
5.13.4.1 Safety factor. Where positioning of the
platform is accomplished by wire rope or chain, the
system shall prevent motion unintended by the operator in
the event of failure of a single wire rope or chain. The
safety factor of the wire rope or chain shall not be less
than 8 to 1 based on ultimate strength.
5.13.4.2 Unintended platform motion. Where
positioning of the platform is accomplished by wire rope
or chains, the system shall prevent motion unintended by
the operator in the event of failure of a single wire rope or
chain.
5.13.5 Unintended retraction of outriggers or
stabilizers. Hydraulically or pneumatically actuated
