ASME B30.2-2011.pdf

This is an excerpt from ASME B30.2-2011, a technical standard for the inspection and testing of overhead and gantry cranes. The document establishes comprehensive inspection and testing criteria to ensure cranes perform safely and as intended. It defines five types of inspections: initial inspection (visual and audible examination of new or altered equipment prior to use), functional test inspection (operational examination at shift start), frequent inspection (visual and audible examination at intervals based on usage—monthly for normal service, weekly to monthly for heavy service, and daily to weekly for severe service), periodic inspection (detailed annual to quarterly examination), and inspection of equipment not in regular use (inspection required before return to service after idle periods exceeding one year). Inspections must be performed by designated personnel with determinations made by qualified persons regarding hazard identification.

The standard further addresses rope inspection requirements, including frequent visual rope inspection at shift start to identify gross damage such as kinking, core protrusion, corrosion, broken strands, and distorted wires, with detailed periodic rope inspection covering the entire rope length and requiring determination of whether continued use constitutes a hazard. Testing provisions include operational tests for new, reinstalled, altered, repaired, and modified cranes covering lifting/lowering, trolley travel, bridge travel, and hoist-limit device functions, as well as load testing conducted between 100% and 125% of rated load unless otherwise recommended. The document additionally covers crane operator training, operational responsibilities including pre-lift verification procedures and load safety protocols, management responsibilities for operator assignment and verification, planned engineered lifts exceeding rated capacity with specific load limitations and frequency restrictions, and hoist limit device operation requirements and signal standards for crane operations.
