Surface preparation and painting to confirm that the surfaces to be
painted were properly blast-cleaned and the paint coats were applied in accordance
with the paint manufacturer's recommendations.
Wire rope breaking strength and positive traceability to the
Shaft and coupling alignment readings to demonstrate compliance with
the coupling manufacturer's alignment recommendations. The certification must
include the identification and location of the coupling, the method of alignment,
manufacturer's recommendations, and the actual alignment (both offset and angular)
that was obtained.
Adequacy of rotate bearing and installation, to confirm the bearing
manufacturer's approval of the selection, rigidity and accuracy of the mounting
structure, and tensioning of the fasteners.
Hydraulic fluid cleanliness of the hydraulic system to confirm that
initial condition complies with the specification criteria.
Torsional vibration analysis to confirm that the diesel engine-
generator set is free of damaging torsional frequencies in the normal operating
Diesel engine emissions authorization/approval documents to confirm
compliance with the local air quality regulations for the crane as a new emissions
Air storage tank inspection and pressure test results and
distribution to the appropriate local authority to verify compliance with the
ANSI/ASME Boiler and Pressure Vessel code. (A copy of the certificate must be
attached to the tank.)
Approval of periodic overload testing (up to 130 percent of rated
capacity) without detrimental effects on the equipment and continued validity of
the manufacturer's warranty.
Technical Manuals. All cranes must be accompanied by a technical manual.
Technical manuals for custom designed cranes are normally comprised of operating
instructions, assembly and sub-assembly drawings (which are extracted from its
technical documentation drawing set), and catalog cuts of standard commercial
items with the manufacturers' literature for maintenance, adjustment, inspection,
troubleshooting, and repair instructions. Manufacturers' literature usually
includes identification of all parts and a listing of authorized service centers.
Technical manuals for standard commercial cranes limit their contents to
the safe operation and maintenance instructions. Normally they do not
permit/approve any significant repairs due to liability concerns. Damaged or
malfunctioning components must be returned to the manufacturer for repairs, and
only the manufacturer's replacement parts may be used in place of obsolete parts.
Such technical manuals are normally the only available documentation for
