34.1. Cranes and derricks.
(a) General requirements.
(1) The employer shall comply with the
				manufacturer's specifications and limitations applicable to the operation of
				any and all cranes and derricks.
When manufacturer's specifica­tions are not
				  available, the limitations assigned to the equipment shall be based on the
				  deter­minations of a qualified engineer competent in this field and such
				  determinations will be appropriately documented and recorded. Attachments used
				  with cranes shall not exceed the capacity, rating, or scope recommended by the
				  manufacturer.
(2) Rated
				load capacities, and recommended operating speeds, special hazard warnings, or
				instruction, shall be conspicu­ously posted on all equipment.
				Instructions or warnings shall be visible to the operator while he is at his
				control station.
(3) Hand signals
				to crane and derrick operators shall be those prescribed by the applicable ANSI
				standard for the type of crane in use. An illustration of the signals shall be
				posted at the job site.
(4) The
				employer shall designate a competent person who shall inspect all
				ma­chinery and equipment each shift prior to each use, and during use,
				to make sure it is in safe operating condi­tion. Any deficiencies shall
				be repaired, or defective parts replaced, before continued use.
(5) A thorough, annual inspec­tion of
				the hoisting machinery shall be made by a competent person, or by a private
				agency recognized by the United States Department of Labor. The employer shall
				maintain a record of the time and dates and results of each inspection for each
				hoisting machine and piece of equip­ment.
(6) Wire rope shall be taken out of service
				when any of the following condi­tions exist:
(i) In running ropes, six (6) randomly
				distributed broken wires or three (3) broken wires in one (1) lay;
(ii) Wear of one-third (1/3) the original
				diameter of outside individual wires. Kinking, crushing, bird caging, or any
				other damage resulting in distortion of the rope structure;
(iii) Evidence of any heat damage from any
				cause;
(iv) Reductions from
				nomi­nal diameter of more than one-sixty-four­th (1/64) inch for
				diameters up to and including five-sixteenths (5/16) inch, one-thirty-two
				(1/32) inches for diameters three-eights (3/8) inch to and including one-half
				(1/2) inch, three-sixty-fourths (3/64) inch, for diameters nine-sixteenths
				(9/16) inch to and including three-fourths (3/4) inch, one-sixteenths (1/16)
				inch for diameters seven-eights (7/8) inch to one and one-eights (1 1/8) inches
				inclusive, three-thirty-two (3/32) inch for diameters one and one-quarter (1
				1/4) to one and one-half (1 1/2) inches inclusive;
(v) In standing ropes, more than two (2)
				broken wires in one (1) lay in sections beyond end connections or more than one
				(1) broken wire at an end connection.
(vi) Wire rope safety factors shall be in
				accordance with American National Standards Institute B30.5-1968 or SAE
				J959-1966.
(7) Belts,
				gears, shafts, pulleys, sprockets, spindles, drums, fly wheels, chains, or
				other reciprocating, rotating, or other mov­ing parts or equipment shall
				be guarded if such parts are exposed to contact by employees or otherwise
				create a hazard. Guarding shall meet the requirements of the American
				Na­tional Standards Institute B15.1-1958 Rev. Safety code for Mechanical
				Power Transmis­sion Apparatus.
(8) Accessible areas within the swing radius
				of the rear of the rotating super­structure of the crane, either
				permanently or temporarily mounted, shall be barricaded in such a manner as to
				prevent an employee from being struck or crushed by the crane.
(9) All exhaust pipes shall be guarded or
				insulated in areas where contact by employees is possible in the performance of
				normal duties.
(10) Whenever
				internal combus­tion engine powered equipment exhausts in enclosed
				spaces, tests shall be made and re­corded to see that employees are not
				exposed to unsafe concentra­tions of toxic gases or oxygen deficient
				atmospheres.
(11) All windows in
				cabs shall be of safety glass, or equivalent, that introduces no visible
				distortion that will interfere with the safe operation of the
				machine.
(12)
(i) Where necessary for rigging or service
				require­ments, a ladder, or steps, shall be provided to give access to a
				cab roof.
(ii) Guardrails,
				handholds, and steps shall be provided on cranes for each access to the car and
				cab, conforming the ANSI B30.5.
(iii) Platforms and walkways shall have
				anti-skid surfaces.
(13)
				Fuel tank filler pipe shall be located in such a position, or protected in such
				a manner, as not to allow spill or overflow to run onto the engine, exhaust, or
				electrical equipment of any machine being fueled.
(i) An accessible fire extin­guisher
				of 5BC rating, or higher, shall be available at all operator stations or cabs
				of equipment.
(ii) All fuels shall
				be trans­ported, stored, and handled to meet the rules of Subpart F of
				this part. When fuel is trans­ported by vehicles on public highways
				Depart­ment of Transpor­tation rules contained in 49 CFR Parts
				177 and 393 concerning such vehic­ular transportation are considered
				applicable.
(14) Except
				where electrical distribution and transmission lines have been deenergized and
				visibly grounded at point of work or where insulating barriers, not a part of
				or an attachment to the equipment or machin­ery, have been erected to
				prevent physical contact with the lines, equipment or machines shall be
				operated proximate to power lines only in accordance with the following:
(i) For lines rated fifty (50)kV. or below,
				minimum clearance be­tween the lines and any part of the crane or load
				shall be ten (10) feet;
(ii) For
				lines rated over fifty (50)kV., minimum clearance between the lines and any
				part of the crane or load shall be ten (10) feet plus four-tenths (0.4) inch
				for each one (1)kV. over fifty (50)kV., or twice the length of the line
				insulator, but never less than ten (10) feet;
(iii) In transit with no load and boom
				lowered, the equipment clearance shall be a minimum of four (4) feet for
				voltag­es, less than forty (40)kV., up to and including three hundred
				forty-five (345)kV. and sixteen (16) feet for voltages up to and including
				seven hundred fifty (750)kV;
(iv) A
				person shall be desig­nated to observe clearance of the equipment and
				give timely warning for all operations where it is difficult for the operator
				to main­tain the desired clearance by visual means;
(v) Cage-type boom guards, insulating links,
				or proximity warning devices may be used on cranes, but the use of such devices
				shall not alter the requirements of any other regulation of this part even if
				such device is required by law or regulation.
(vi) Any overhead wire shall be considered to
				be an energized line unless and until the person owning such line or the
				electrical utility authorities indicate that it is not an energized line and it
				has been visibly grounded;
(vii)
				Prior to work near transmitter towers where an electric charge can be induced
				in the equipment or materials begin handled, the transmitter shall be
				deenergized or tests shall be made to determine if electrical charge is induced
				on the crane. The following precautions shall be taken when necessary to
				dissipate induced voltages:
(a) The equipment
				shall be provided with an electrical ground directly to the upper rotating
				structure supporting the boom;
(b)
				Ground jumper cables shall be attached to materials being handled by boom
				equipment when electrical charge is induced while working near
				ener­gized transmitters. Crews shall be provided with nonconductive
				poles having large alligator clips or other similar protection to attach the
				ground cable to the load; and
(c)
				Combustible and flammable materials shall be removed from the immediate area
				prior to operation.
(15) No modifications or addi­tions
				which affect the capacity or safe opera­tion of the equipment shall be
				made by the employer without the manufacturer's written approval. If such
				modifications or changes are made, the capacity, operation and maintenance
				instruction plates, tags, or decals, shall be changed accordingly. In no case
				shall the original safety factor of the equipment be reduced.
(16) The employer shall comply with Power
				Crane and Shovel Association Mobile Hydraulic Crane Standard No. 2.
(17) Sideboom cranes mounted on wheel or
				crawler tractors shall meet the re­quirements of SAE
				J743-1964.
