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.
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.
The following additional safety devices are required for floating cranes and derricks on barges:
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.
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.
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.
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.
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.
Most provisions of this standard apply to dedicated pile drivers. The only exceptions are the following:
Most provisions of this standard apply to sideboom cranes. The exceptions are:
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").
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:
