Specialized Cranes and Equipment

Floating Crane

Floating Cranes/Derricks and Land Cranes/Derricks on Barges

Section 1437 contains supplemental requirements for floating cranes/derricks and land cranes/derricks on barges, pontoons, vessels or other means of flotation (i.e., vessel/flotation device).

The requirements of Section 1437 do not apply when using jacked barges when the jacks are deployed to the river, lake, or sea bed and the barge is fully supported by the jacks. Because this equipment is highly specialized and is not used by most construction employers, this course will only address a few of the areas where additional or different requirements are specified for this type of equipment.

Inspections

Additional items must be inspected during the shift, monthly, and annual inspections. In addition, every four years, a marine engineer, marine architect, licensed surveyor, or other qualified person who has expertise with respect to vessels/flotation devices must survey the internal portion of the barge, pontoons, vessel, or other means of flotation.

Safety Devices

diver
Should a crane or derrick be used for any other purpose if it’s lifting a diver out of the water?

The following additional safety devices are required for floating cranes and derricks on barges:

  • barge, pontoon, vessel, or other means of flotation list and trim device
  • positive equipment house lock
  • wind speed and direction indicator (if a competent person determines that wind is a factor that needs to be considered)

Working with a Diver

When a crane/derrick is used to lift a diver or divers into and out of the water, it must not be used for any other purpose until all the divers are back on board.

crane floating
Does the rated capacity need to be reduced if a land crane is used on a flotation device operating on water?

Land Cranes/Derricks on Floatation Devices

The rated capacity must be reduced to take into account the additional sources of instability (list, trim, wave action, and wind) resulting from operating on water. Alternative means of physical attachment and an exception to the requirement for physical attachment are specified.

Equipment Designed for Use on Floatation Devices

Requirements for maximum list, trim, and wind speed are specified. Additional rules to ensure the structural integrity and stability of the equipment apply to employer-made (as opposed to manufacturer-made) equipment.

Overhead & Gantry Cranes

If an overhead crane is permanently installed in a facility, which standard applies?

Most overhead and gantry cranes are used in general industry rather than construction work. In some cases, overhead and gantry cranes that are usually used in general industry may engage in construction work when they are used to renovate the facility in which they are installed.

To prevent the same crane from being subject to general industry and construction standards at different times, Section 1438 provides that OSHA's General Industry standard (29 CFR 1910.179) applies to an overhead or gantry crane that is permanently installed in a facility.

For overhead and gantry cranes that are not permanently installed in a facility, Section 1438 lists the provisions of this standard that apply.

  • Sections 1400 through 1414
  • Sections 1417 through 1425
  • Section 1426(d)
  • Sections 1427 through 1434
  • Sections 1437, 1439, and 1441

In addition, certain provisions of 29 CFR 1910.179 and certain provisions of ASME B30.2-2005 (Overhead and Gantry Cranes) apply to overhead and gantry cranes not permanently installed in a facility. These provisions are listed in section 1438.

Dedicated Pile Drivers

Pile Driver

Most provisions of this standard apply to dedicated pile drivers. The only exceptions are the following:

  • the requirement in section 1416 for an anti-two-blocking device;
  • certain requirements of section 1433 that apply to design, construction, and testing of mobile cranes; and
  • the requirement in section 1416 for load weighing and similar devices applies only to dedicated pile drivers manufactured after November 8, 2011.

Sideboom Cranes

Most provisions of this standard apply to sideboom cranes. The exceptions are:

  • Section 1402 (Ground conditions)
  • Section 1415 (Safety devices)
  • Section 1416 (Operational aids)
  • Section 1427 (Operator qualification and certification)

In addition, instead of the provision on boom free fall found in section 1426, sideboom cranes in which the boom is designed to free fall (live boom) are permitted only if manufactured prior to November 8, 2010. Section 1440 also specifies that sideboom cranes mounted on wheel or crawler tractors must meet certain listed requirements of ASME B30.14-2004 ("Side Boom Tractors").

Equipment with a Rated Hoisting/Lifting Capacity of 2,000 Pounds or Less

capacity
Your employees are at risk if they are not properly trained to safely use equipment with a rated capacity of 2,000 lbs. or less.

Although equipment with a capacity of 2,000 pounds or less does not require all of the precautions required for heavier equipment, its operation still presents significant hazards that can cause death or injury. For example, operation near energized power lines requires the same precautions as heavier equipment because the potential for electrocution is the same.

Section 1441 lists the provisions of the standard that apply to equipment with a capacity of 2,000 pounds or less and those for which modified requirements apply. The most significant differences are:

  • The requirement for operator qualification/certification in section 1427 does not apply. Instead, the employer must train each operator on the safe operation of the equipment before the operator may operate the equipment.
  • The requirements for shift, monthly, and annual inspections in section 1412 do not apply. However, post-assembly inspections and the wire rope inspections required by section 1413 must be conducted.
  • More limited assembly/disassembly requirements apply.
  • The safety devices and operational aids listed in sections 1415 – 1416 need not be used, except for two-block protection. However, safety devices and operational aids that are part of the original equipment must be maintained in accord with manufacturer procedures.
  • Signal persons must be adequately trained but need not meet the qualification requirements of section 1428.
  • Equipment covered by Section 1441 must not be used to hoist personnel.
