director, irrespective of the person's formal job title or whether the person is non-management or management personnel.
Articulating crane means a crane whose boom consists of a series of folding, pin connected structural members,
typically manipulated to extend or retract by power from hydraulic cylinders.
Assembly/Disassembly means the assembly and/or disassembly of equipment covered under this standard. With
regard to tower cranes, “erecting and climbing” replaces the term “assembly,” and “dismantling” replaces the term
“disassembly.” Regardless of whether the crane is initially erected to its full height or is climbed in stages, the process of
increasing the height of the crane is an erection process.
Assist crane means a crane used to assist in assembling or disassembling a crane.
Attachments means any device that expands the range of tasks that can be done by the equipment. Examples
include, but are not limited to: An auger, drill, magnet, pile-driver, and boom-attached personnel platform.
Audible signal means a signal made by a distinct sound or series of sounds. Examples include, but are not limited to,
sounds made by a bell, horn, or whistle.
Blocking (also referred to as “cribbing”) is wood or other material used to support equipment or a component and
distribute loads to the ground. It is typically used to support lattice boom sections during assembly/disassembly and under
outrigger and stabilizer floats.
Boatswain's chair means a single-point adjustable suspension scaffold consisting of a seat or sling (which may be
incorporated into a full body harness) designed to support one employee in a sitting position.
Bogie means “travel bogie,” which is defined below.
Boom (equipment other than tower crane) means an inclined spar, strut, or other long structural member which
supports the upper hoisting tackle on a crane or derrick. Typically, the length and vertical angle of the boom can be varied
to achieve increased height or height and reach when lifting loads. Booms can usually be grouped into general categories
of hydraulically extendible, cantilevered type, latticed section, cable supported type or articulating type.
Boom (tower cranes): On tower cranes, if the “boom” (i.e., principal horizontal structure) is fixed, it is referred to as a
jib; if it is moveable up and down, it is referred to as a boom.
Boom angle indicator means a device which measures the angle of the boom relative to horizontal.
http://www.ecfr.gov/cgi-bin/text-idx?SID=c07fa7232c612e462a35a0b76a925910&mc=true&node=sp29.8.1926.cc&rgn=div6[2/21/2017 2:10:00 PM]
eCFR — Code of Federal Regulations
Boom hoist limiting device includes boom hoist disengaging device, boom hoist shut-off, boom hoist disconnect, boom
hoist hydraulic relief, boom hoist kick-outs, automatic boom stop device, or derricking limiter. This type of device
disengages boom hoist power when the boom reaches a predetermined operating angle. It also sets brakes or closes
valves to prevent the boom from lowering after power is disengaged.
Boom length indicator indicates the length of the permanent part of the boom (such as ruled markings on the boom)
or, as in some computerized systems, the length of the boom with extensions/attachments.
Boom stop includes boom stops, (belly straps with struts/standoff), telescoping boom stops, attachment boom stops,
and backstops. These devices restrict the boom from moving above a certain maximum angle and toppling over backward.
Boom suspension system means a system of pendants, running ropes, sheaves, and other hardware which supports
the boom tip and controls the boom angle.
Builder means the builder/constructor of equipment.
Center of gravity: The center of gravity of any object is the point in the object around which its weight is evenly

Certified welder means a welder who meets nationally recognized certification requirements applicable to the task
being performed.
Climbing means the process in which a tower crane is raised to a new working height, either by adding additional
tower sections to the top of the crane (top climbing), or by a system in which the entire crane is raised inside the structure
(inside climbing).
Come-a-long means a mechanical device typically consisting of a chain or cable attached at each end that is used to
facilitate movement of materials through leverage.
Competent person means one who is capable of identifying existing and predictable hazards in the surroundings or
working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take
prompt corrective measures to eliminate them.
Controlled load lowering means lowering a load by means of a mechanical hoist drum device that allows a hoisted
load to be lowered with maximum control using the gear train or hydraulic components of the hoist mechanism. Controlled
load lowering requires the use of the hoist drive motor, rather than the load hoist brake, to lower the load.
Controlling entity means an employer that is a prime contractor, general contractor, construction manager or any other
legal entity which has the overall responsibility for the construction of the project—its planning, quality and completion.

reaches the flange, and begins to wrap back in the opposite direction.
Dedicated channel means a line of communication assigned by the employer who controls the communication system
to only one signal person and crane/derrick or to a coordinated group of cranes/derricks/signal person(s).
Dedicated pile-driver is a machine that is designed to function exclusively as a pile-driver. These machines typically
have the ability to both hoist the material that will be pile-driven and to pile-drive that material.
Dedicated spotter (power lines): To be considered a dedicated spotter, the requirements of §1926.1428 (Signal
person qualifications) must be met and his/her sole responsibility is to watch the separation between the power line and
the equipment, load line and load (including rigging and lifting accessories), and ensure through communication with the
operator that the applicable minimum approach distance is not breached.
Directly under the load means a part or all of an employee is directly beneath the load.
Dismantling includes partial dismantling (such as dismantling to shorten a boom or substitute a different component).
Drum rotation indicator means a device on a crane or hoist which indicates in which direction and at what relative
speed a particular hoist drum is turning.
Electrical contact occurs when a person, object, or equipment makes contact or comes in close proximity with an
energized conductor or equipment that allows the passage of current.
Employer-made equipment means floating cranes/derricks designed and built by an employer for the employer's own
use.
Encroachment is where any part of the crane, load line or load (including rigging and lifting accessories) breaches a
minimum clearance distance that this subpart requires to be maintained from a power line.
Equipment means equipment covered by this subpart.

load-attaching equipment, such as, the load block, ropes, slings, shackles, and any other ancillary attachment.
Load moment (or rated capacity) indicator means a system which aids the equipment operator by sensing (directly or
indirectly) the overturning moment on the equipment, i.e., load multiplied by radius. It compares this lifting condition to the
equipment's rated capacity, and indicates to the operator the percentage of capacity at which the equipment is working.
Lights, bells, or buzzers may be incorporated as a warning of an approaching overload condition.
Load moment (or rated capacity) limiter means a system which aids the equipment operator by sensing (directly or
indirectly) the overturning moment on the equipment, i.e., load multiplied by radius. It compares this lifting condition to the
equipment's rated capacity, and when the rated capacity is reached, it shuts off power to those equipment functions which
can increase the severity of loading on the equipment, e.g., hoisting, telescoping out, or luffing out. Typically, those
functions which decrease the severity of loading on the equipment remain operational, e.g., lowering, telescoping in, or
luffing in.
Locomotive crane means a crane mounted on a base or car equipped for travel on a railroad track.
Luffing jib limiting device is similar to a boom hoist limiting device, except that it limits the movement of the luffing jib.
Marine hoisted personnel transfer device means a device, such as a “transfer net,” that is designed to protect the
employees being hoisted during a marine transfer and to facilitate rapid entry into and exit from the device. Such devices
do not include boatswain's chairs when hoisted by equipment covered by this standard.

otherwise specified.
Pendants includes both wire and bar types. Wire type: A fixed length of wire rope with mechanical fittings at both ends
for pinning segments of wire rope together. Bar type: Instead of wire rope, a bar is used. Pendants are typically used in a
latticed boom crane system to easily change the length of the boom suspension system without completely changing the
rope on the drum when the boom length is increased or decreased.
Personal fall arrest system means a system used to arrest an employee in a fall from a working level. It consists of an
anchorage, connectors, a body harness and may include a lanyard, deceleration device, lifeline, or suitable combination of
these.
Portal crane is a type of crane consisting of a rotating upperstructure, hoist machinery, and boom mounted on top of a

Tower crane is a type of lifting structure which utilizes a vertical mast or tower to support a working boom (jib) in an
elevated position. Loads are suspended from the working boom. While the working boom may be of the fixed type
(horizontal or angled) or have luffing capability, it can always rotate to swing loads, either by rotating on the top of the
tower (top slewing) or by the rotation of the tower (bottom slewing). The tower base may be fixed in one location or
ballasted and moveable between locations. Mobile cranes that are configured with luffing jib and/or tower attachments are
not considered tower cranes under this section.

direct communication with the operator to inform the operator when this point is reached.
(iii) Anti two-blocking device. The tower crane must be equipped with a device which automatically prevents damage
from contact between the load block, overhaul ball, or similar component, and the boom tip (or fixed upper block or similar
component). The device(s) must prevent such damage at all points where two-blocking could occur. Temporary alternative
measures: Clearly mark the cable (so it can be seen by the operator) at a point that will give the operator sufficient time to
stop the hoist to prevent two-blocking, or use a spotter who is in direct communication with the operator to inform the
operator when this point is reached.
(iv) Hoist drum lower limiting device. Tower cranes manufactured after November 8, 2011 must be equipped with a
device that prevents the last 2 wraps of hoist cable from being spooled off the drum. Temporary alternative measures:
Mark the cable (so it can be seen by the operator) at a point that will give the operator sufficient time to stop the hoist prior
to last 2 wraps of hoist cable being spooled off the drum, or use a spotter who is in direct communication with the operator
to inform the operator when this point is reached
(v) Load moment limiting device. The tower crane must have a device that prevents moment overloading. Temporary
alternative measures: A radius indicating device must be used (if the tower crane is not equipped with a radius indicating
device, the radius must be measured to ensure the load is within the rated capacity of the crane). In addition, the weight of
the load must be determined from a source recognized by the industry (such as the load's manufacturer), or by a
calculation method recognized by the industry (such as calculating a steel beam from measured dimensions and a known
per foot weight), or by other equally reliable means. This information must be provided to the operator prior to the lift.
(vi) Hoist line pull limiting device. The capacity of the hoist must be limited to prevent overloading, including each
individual gear ratio if equipped with a multiple speed hoist transmission. Temporary alternative measures: The operator
must ensure that the weight of the load does not exceed the capacity of the hoist (including for each individual gear ratio if
equipped with a multiple speed hoist transmission).
(vii) Rail travel limiting device. The travel distance in each direction must be limited to prevent the travel bogies from

eCFR — Code of Federal Regulations
Unintended Dangerous Boom Movement
1. Section 1926.1404(f)(1) provides that when pins (or similar devices) are being removed, employees must not be
under the boom, jib, or other components, except where the requirements of §1926.1404(f)(2) are met. The exception in
§1926.1404(f)(2) applies when the employer demonstrates that site constraints require one or more employees to be
under the boom, jib, or other components when pins (or similar devices) are being removed. In such a situation, the A/D
director must implement procedures that minimize the risk of unintended dangerous movement and minimize the duration
and extent of exposure under the boom.
The following scenario is an example of how the exception applies: A boom cannot be disassembled on the ground
because of aboveground piping (as might be found, for example, in an oil refinery) that precludes lowering the boom to the
ground. The boom must therefore be disassembled in the air, and the employees who remove the pins must perform that
work from an aerial lift whose base is positioned on one side (the near side) of the boom. To gain access to the pins on the
far side, the aerial lift basket must move under the boom, since, due to lack of room, the aerial lift cannot be repositioned
on the far side. Due to lack of room, the aerial lift cannot be repositioned on the far side, so the aerial basket must move
under the boom to gain access to the pins on the far side.
To minimize the risk of unintended dangerous movement while the pins are removed, the A/D director uses an assist
crane that is rigged to support the boom section that is being detached, using particular care to ensure that the section end
that is near the employee(s) removing the pins is well supported. The duration and extent of exposure is minimized by
removing the far side pins first, moving the aerial lift basket as soon as possible to the near side so that the employees are
no longer under the boom, and then removing the near side pins.
2. Section 1926.1404(h)(6)(i) provides that, during assembly/disassembly, the center of gravity of the load must be
identified if that is necessary for the method used for maintaining stability. Section 1926.1404(h)(6)(ii) states that, where
there is insufficient information to accurately identify the center of gravity, measures designed to prevent unintended
dangerous movement resulting from an inaccurate identification of the center of gravity must be used.
An example of the application of §1926.1404(h)(6)(ii) is as follows: The boom is assembled by lowering boom
sections sequentially into place using an assist crane. The A/D director's plan is to keep the boom sections stable while
they are lowered into place by attaching the assist crane hoist line above the center of gravity of each section. However, in
assembling the non-symmetrical top section of the boom, the A/D director is not able to determine where to attach the
assist crane hoist line so that it is above the center of gravity. In this situation, before raising the section, all personnel are
kept clear of the section and the section is first raised a few inches to determine whether it tips when raised (if it did tip, it
would indicate it is not rigged over the center of gravity). If this occurs, the hoist line is repositioned and the procedure
repeated (with employees kept clear of the section while it is raised) until the A/D director determines that it is rigged over
the center of gravity and can be moved into place without dangerous movement.
