Study Notes
ASME B30.2-2022 Safety Standard
- The standard is a revision of ASME B30.2-2016 and was issued on August 24, 2022, with the next edition scheduled for publication in 2027.
Overhead and Gantry Cranes
- Top-running bridge, single or multiple girder, top-running trolley hoist cranes are covered by this standard.
- The standard includes provisions for construction, installation, operation, inspection, and maintenance of hand-operated and power-driven overhead and gantry cranes.
Rope Inspection
- Rope inspection should be performed to identify damage, such as:
- Distortion (kinking, crushing, unstranding, birdcaging, main strand displacement, or core protrusion)
- General corrosion
- Broken or cut strands
- Number, distribution, and type of visible broken wires
- When damage is discovered, the rope should be removed from service or inspected as detailed in para. 2-2.2.3(b).
Periodic Rope Inspection
- The inspection frequency should be determined by a qualified person and based on factors such as:
- Expected rope life
- Severity of environment
- Percent of capacity lifts
- Frequency rates of operation
- Exposure to shock loads
- Inspections should cover the entire length of rope, and any deterioration resulting in appreciable loss of original strength should be noted.
Braking Methods
- Braking methods include:
- Countertorque (plugging)
- Dynamic braking
- Eddy current braking
- Emergency braking
Warnings and Controls
- Safety labels or labels should be affixed to the pendant station, portable operating station, or load block, and should include cautionary language against:
- Lifting more than rated load
- Operating hoist when load is not centered under hoist
- Operating hoist with twisted, kinked, or damaged chain or rope
- Operating damaged or malfunctioning crane
- Controllers should be legibly marked to indicate the function and direction of movement.
Wind Speed Indicators
- A wind speed indicating device should be provided for cranes used outdoors, and should give a visible and audible alarm to the crane operator at a predetermined wind speed.
Operational Testing
- Operational testing of altered, repaired, and modified cranes may be limited to the functions affected by the alteration, repair, or modification, as determined by a qualified person.
