§ 1910.67 Vehicle-mounted
elevating
and rotating work platforms.
(a) Definitions applicable to this section—(1) Aerial device. Any vehicle—
mounted device, telescoping or articulating, or both, which is used to position personnel.
(2) Aerial ladder. An aerial device consisting of a single- or multiple-section
extensible ladder.
(3) Articulating boom platform. An aerial device with two or more hinged
boom sections.
(4) Extensible boom platform. An aerial
device (except ladders) with a telescopic or extensible boom. Telescopic
derricks with personnel platform attachments shall be considered to be extensible boom platforms when used
with a personnel platform.
(5) Insulated aerial device. An aerial
device designed for work on energized
lines and apparatus.
(6) Mobile unit. A combination of an
aerial device, its vehicle, and related
equipment.
(7) Platform. Any personnel-carrying
device (basket or bucket) which is a
component of an aerial device.
(8) Vehicle. Any carrier that is not
manually propelled.
(9) Vertical tower. An aerial device designed to elevate a platform in a substantially vertical axis.
(b) General requirements. (1) Unless
otherwise provided in this section, aerial devices (aerial lifts) acquired on or
after July 1, 1975, shall be designed and
constructed in conformance with the
applicable requirements of the American National Standard for ‘‘Vehicle
Mounted Elevating and Rotating Work
Platforms,’’ ANSI A92.2—1969, including appendix, which is incorporated by
reference as specified in § 1910.6. Aerial
lifts acquired for use before July 1, 1975
which do not meet the requirements of
ANSI A92.2—1969, may not be used after
July 1, 1976, unless they shall have been
modified so as to conform with the applicable design and construction requirements of ANSI A92.2—1969. Aerial
devices include the following types of
vehicle-mounted aerial devices used to
elevate personnel to jobsites above
ground: (i) Extensible boom platforms,
(ii) aerial ladders, (iii) articulating
boom platforms, (iv) vertical towers,
and (v) a combination of any of the

§ 1910.67

above. Aerial equipment may be made
of metal, wood, fiberglass reinforced
plastic (FRP), or other material; may
be powered or manually operated; and
are deemed to be aerial lifts whether or
not they are capable of rotating about
a substantially vertical axis.
(2) Aerial lifts may be ‘‘field modified’’ for uses other than those intended by the manufacturer, provided
the modification has been certified in
writing by the manufacturer or by any
other equivalent entity, such as a nationally recognized testing laboratory,
to be in conformity with all applicable
provisions of ANSI A92.2—1969 and this
section, and to be at least as safe as
the equipment was before modification.
(3) The requirements of this section
do not apply to firefighting equipment
or to the vehicles upon which aerial devices are mounted, except with respect
to the requirement that a vehicle be a
stable support for the aerial device.
(4) For operations near overhead electric lines, see § 1910.333(c)(3).
(c) Specific requirements—(1) Ladder
trucks and tower trucks. Before the
truck is moved for highway travel, aerial ladders shall be secured in the lower
traveling position by the locking device above the truck cab, and the
manually operated device at the base
of the ladder, or by other equally effective means (e.g., cradles which prevent
rotation of the ladder in combination
with positive acting linear actuators).
(2) Extensible and articulating boom
platforms. (i) Lift controls shall be tested each day prior to use to determine
that such controls are in safe working
condition.
(ii) Only trained persons shall operate an aerial lift.
(iii) Belting off to an adjacent pole,
structure, or equipment while working
from an aerial lift shall not be permitted.
(iv) Employees shall always stand
firmly on the floor of the basket, and
shall not sit or climb on the edge of the
basket or use planks, ladders, or other
devices for a work position.
(v) A body belt shall be worn and a
lanyard attached to the boom or basket when working from an aerial lift.
(vi) Boom and basket load limits
specified by the manufacturer shall not
be exceeded.

29 CFR Ch. XVII (7–1–14 Edition)

(vii) The brakes shall be set and outriggers, when used, shall be positioned
on pads or a solid surface. Wheel
chocks shall be installed before using
an aerial lift on an incline.
(viii) An aerial lift truck may not be
moved when the boom is elevated in a
working position with men in the basket, except for equipment which is specifically designed for this type of operation in accordance with the provisions
of paragraphs (b)(1) and (b)(2) of this
section.
(ix) Articulating boom and extensible
boom platforms, primarily designed as
personnel carriers, shall have both
platform (upper) and lower controls.
Upper controls shall be in or beside the
platform within easy reach of the operator. Lower controls shall provide for
overriding the upper controls. Controls
shall be plainly marked as to their
function. Lower level controls shall not
be operated unless permission has been
obtained from the employee in the lift,
except in case of emergency.
(x) Climbers shall not be worn while
performing work from an aerial lift.
(xi) The insulated portion of an aerial
lift shall not be altered in any manner
that might reduce its insulating value.
(xii) Before moving an aerial lift for
travel, the boom(s) shall be inspected
to see that it is properly cradled and
outriggers are in stowed position, except
as
provided
in
paragraph
(c)(2)(viii) of this section.
(3) Electrical tests. Electrical tests
shall be made in conformance with the
requirements of ANSI A92.2—1969, Section 5. However, equivalent DC voltage
tests may be used in lieu of the AC
voltage test specified in A92.2—1969. DC
voltage tests which are approved by
the equipment manufacturer or equivalent entity shall be considered an
equivalent test for the purpose of this
paragraph (c)(3).
(4) Bursting safety factor. All critical
hydraulic and pneumatic components
shall comply with the provisions of the
American National Standards Institute
standard, ANSI A92.2—1969, Section 4.9
Bursting Safety Factor. Critical components are those in which a failure
would result in a free fall or free rotation of the boom. All noncritical components shall have a bursting safety
factor of at least two to one.

(5) ‘‘Welding standards.’’ All welding
shall conform to the following American Welding Society (AWS) Standards
which are incorporated by reference as
specified in § 1910.6, as applicable:
(i) Standard Qualification Procedure,
AWS B3.0—41.
(ii) Recommended Practices for
Automotive Welding Design, AWS
D8.4–61.
(iii) Standard Qualification of Welding Procedures and Welders for Piping
and Tubing, AWS D10.9–69.
(iv) Specifications for Welding Highway and Railway Bridges, AWS D2.0–69.

§ 1910.68

Manlifts.

(a) Definitions applicable to this section—(1) Handhold (Handgrip). A handhold is a device attached to the belt
which can be grasped by the passenger
to provide a means of maintaining balance.
(2) Open type. One which has a handgrip surface fully exposed and capable
of being encircled by the passenger’s
fingers.
(3) Closed type. A cup-shaped device,
open at the top in the direction of travel of the step for which it is to be used,
and closed at the bottom, into which
the passenger may place his fingers.
(4) Limit switch. A device, the purpose
of which is to cut off the power to the
motor and apply the brake to stop the
carrier in the event that a loaded step
passes the terminal landing.
(5) Manlift. A device consisting of a
power-driven endless belt moving in
one direction only, and provided with
steps or platforms and handholds attached to it for the transportation of
personnel from floor to floor.
(6) Rated speed. Rated speed is the
speed for which the device is designed
and installed.
(7) Split-rail switch. An electric limit
switch operated mechanically by the
rollers on the manlift steps. It consists
of an additional hinged or ‘‘split’’ rail,
mounted on the regular guide rail, over
which the step rollers pass. It is
springloaded in the ‘‘split’’ position. If
the step supports no load, the rollers
