Fully and clearly define all outputs.
Mark all pertinent or design-governing data items (such as loads,
locations, positions, stresses, etc.) and the corresponding computed values. The
marking of the data items must facilitate easy location and identification of the
structural members on the assembly drawings.
Reference the printout page number of each data item extracted from
the printout and used in the design hand calculations.
Show that all estimated computer program input values are not more
than 3 percent on the unconservative side.
Catalog Cuts. The selection of standard commercial assemblies and
components must be accompanied by manufacturers' technical literature (catalog
cuts). Each catalog cut must be marked-up to fully identify the model or
size/rating of the item and supplemental pages with data or information to
demonstrate specification compliance. Catalog cuts which show modifications beyond
the standard options and all supplemental pages must bear original signatures and
dates of the manufacturer's authorized representative or the responsible PE. Each
catalog cut and supplemental page must identify the crane, drive, and component to
which it applies.
Normally catalog cuts are appropriate for packaged hoists, spreaders,
monorail beams, standard end trucks, gear reducers, brakes, electric motors,
runway electrification, master switches, pushbutton control stations, drive
control equipment, and major hydraulic components. Catalog cuts for widely used
mechanical and electrical components may be omitted.
Certifications. Certifications are required for certain items and
procedures to confirm specification compliance and quality levels of workmanship.
Each certification must bear the original signature and date of the appropriate
responsible individual. Certifications are usually required for the following,
where they apply, but additional certifications may be required in particular
Welders and automatic welding machine operators for qualification
with the requirements of AWS D1.1 or D14.1, as appropriate to the crane type and
the weld types.
Weld inspectors for non-destructive examination of welds according
to American Society of Non-Destructive Testing ASNT TC-1A.
High-strength bolts and nuts to verify U.S. manufacture (with
positive traceability) and rotational capacity test data for each production lot
and bolt-nut combinations.
