(1) All articulating boom cranes in use must meet the applicable requirements for design, inspection, construction, testing, maintenance and operation as prescribed in the ASME B30.22-2010, Safety Standard for Articulating Boom Cranes. It is not the intent of this rule to require retrofitting of existing cranes. However, when an item is being modified, its performance needs to be reviewed by a qualified person and compared to the applicable sections of this rule. For modification requirements see WAC 296-155-53400 (58) and (59). For cranes manufactured prior to the effective date of this rule the design and construction criteria must meet at a minimum, ASME B30.22-1987.

(2) All articulating boom cranes with a winch must have a two-blocking damage prevention feature.

(3) All welding and welding operator qualifications for load sustaining members must be in accordance with ANSI/AWS D14.3.
