(a)
General. The following requirements shall apply to the use of cranes and derricks brought aboard vessels for conducting longshoring operations. They shall not apply to cranes and derricks forming part of a vessel's permanent equipment.
(1)
Certification. Cranes and derricks shall be certificated in accordance with
part 1919 of this chapter.
(2)
Posted weight. The crane weight shall be posted on all cranes hoisted aboard vessels for temporary use.
(3)
Rating chart. All cranes and derricks having ratings that vary with boom length, radius (outreach) or other variables shall have a durable rating chart visible to the operator, covering the complete range of the manufacturers' (or design) capacity ratings. The rating chart shall include all operating radii (outreach) for all permissible boom lengths and jib lengths, as applicable, with and without outriggers, and alternate ratings for optional equipment affecting such ratings. Precautions or warnings specified by the owner or manufacturer shall be included along with the chart.
(4)
Rated loads. The manufacturers' (or design) rated loads for the conditions of use shall not be exceeded.
(5)
Change of rated loads. Designated working loads shall not be increased beyond the manufacturers' ratings or original design limitations unless such increase receives the manufacturers' approval. When the manufacturers' services are not available or where the equipment is of foreign manufacture, engineering design analysis shall be done or approved by a person accredited for certificating the equipment under
part 1919 of this chapter. Engineering design analysis shall be done by a registered professional engineer competent in the field of cranes and derricks. Any structural changes required by the change in rating shall be carried out.
(6)
Radius indicator. When the rated load varies with the boom radius, the crane or derrick shall be fitted with a boom angle or radius indicator visible to the operator.
(7)
Operator's station. The cab, controls and mechanism of the equipment shall be so arranged that the operator has a clear view of the load or signalman, when one is used. Cab glass, when used, shall be safety plate glass or equivalent. Cranes with missing, broken, cracked, scratched, or dirty glass (or equivalent), that impairs operator vision shall not be used. Clothing, tools, and equipment shall be stored so as not to interfere with access, operation, and the operator's view.
(8)
Counterweights or ballast. Cranes shall be operated only with the specified type and amount of ballast or counterweights. Ballast or counterweights shall be located and secured only as provided in the manufacturers' or design specifications, which shall be available for inspection.
(9)
Outriggers. Outriggers shall be used according to the manufacturers' specifications or design data, which shall be available for inspection. Floats, when used, shall be securely attached to the outriggers. Wood blocks or other support shall be of sufficient size to support the outrigger, free of defects that may affect safety, and of sufficient width and length to prevent the crane from shifting or toppling under load.
(10)
Exhaust gases. Engine exhaust gases shall be discharged away from crane operating personnel.
(11)
Electrical/Guarding. Electrical equipment shall be so placed or enclosed that live parts will not be exposed to accidental contact. Designated persons may work on energized equipment only if necessary during inspection, maintenance, or repair; otherwise the equipment shall be stopped and its power source locked out and tagged out.
(12)
Fire extinguisher.
(i)
At least one portable approved or listed fire extinguisher of at least a 5-B— C rating or equivalent shall be accessible in the cab of the crane or derrick.
(ii)
No portable fire extinguisher using carbon tetrachloride or chlorobromomethane extinguishing agents shall be used.
(13)
Rope on drums. At least three full turns of rope shall remain on ungrooved drums, and two turns on grooved drums, under all operating conditions. Wire rope shall be secured to drums by clamps, U-bolts, shackles or equivalent means. Fiber rope fastenings are prohibited.
(14)
Brakes.
(i)
Each independent hoisting unit of a crane shall be equipped with at least one holding brake, applied directly to the motor shaft or gear train.
(ii)
Each independent hoisting unit of a crane shall, in addition to the holding brake, be equipped with a controlled braking means to control lowering speeds.
(iii)
Holding brakes for hoist units shall have not less than the following percentage of the rated load hoisting torque at the point where the brake is applied:
(A)
125 percent when used with an other than mechanically controlled braking means;
(B)
100 percent when used with a mechanically controlled braking means; or
(C)
100 percent when two holding brakes are provided.
(iv)
All power control braking means shall be capable of maintaining safe lowering speeds of rated loads.
(15)
Operating controls. Crane and derrick operating controls shall be clearly marked, or a chart showing their function shall be posted at the operator's position.
(16)
Booms. Cranes with elevatable booms and without operable automatic limiting devices shall be provided with boom stops if boom elevation can exceed maximum design angles from the horizontal.
(17)
Foot pedals. Foot pedals shall have a non-skid surface.
(18)
Access. Ladders, stairways, stanchions, grab irons, foot steps or equivalent means shall be provided as necessary to ensure safe access to footwalks, cab platforms, the cab and any portion of the superstructure that employees must reach.
(c)
Protection for employees being hoisted.
(1)
No employee shall be hoisted by the load hoisting apparatus of a crane or derrick except on a platform meeting the following requirements:
(i)
Enclosed by a railing or other means providing protection equivalent to that described in
§ 1917.112(c) of this chapter;
(ii)
Fitted with toe boards if the platform has open railings;
(iii)
A safety factor of four based on ultimate strength;
(iv)
Bearing a plate or permanent marking indicating maximum load rating, which shall not be exceeded, and the weight of the platform itself;
(v)
Equipped with a device to prevent access doors, when used, from opening accidentally;
(vi)
Equipped with overhead protection for employees on the platform if they are exposed to falling objects or overhead hazards; and
(vii)
Secured to the load line by means other than wedge and socket attachments, unless the free (bitter) end of the line is secured back to itself by a clamp placed as close above the wedge as possible.
(2)
Except in an emergency, the hoisting mechanism of all cranes or derricks used to hoist personnel shall operate only in power up and power down, with automatic brake application when not hoisting or lowering.
(3)
All cranes and derricks used to hoist personnel shall be equipped with an anti-two-blocking device.
(4)
Variable radius booms of a crane or derrick used to hoist personnel shall be so constructed or secured as to prevent accidental boom movement.
(5)
Platforms or devices used to hoist employees shall be inspected for defects before each day's use and shall be removed from service if defective.
(6)
Employees being hoisted shall remain in continuous sight of and communication with the operator or signalman.
(7)
Operators shall remain at the controls when employees are hoisted.
(8)
Cranes shall not travel while employees are hoisted, except in emergencies or in normal tier-to-tier transfer of employees during container operations.
