Initial inspection - Prior to initial use all new and altered cranes shall be inspected to insure
compliance.
Besides that, for gantry cranes in regular service, there are two general classifications of inspections based upon the
intervals at which the inspection should be performed. The intervals in turn are dependent upon the nature of the
critical components of the crane and the degree of their exposure to wear, deterioration, or malfunction. The two
general classifications are herein designated as "frequent"
and
"periodic"
with respective intervals between inspections
as defined below:
1910.179(j)(1)(ii)(a)
Frequent inspection - Daily to monthly intervals.

The following items shall be inspected for defects at intervals as defined above or as specifically indicated, including
observation during operation for any defects which might appear between regular inspections. All deficiencies such as
listed shall be carefully examined and determination made as to whether they constitute a safety hazard:
•
All functional operating mechanisms for maladjustment interfering with proper operation. Daily.
•
Hooks with deformation or cracks. Visual inspection daily; monthly inspection with a certification record which
includes the date of inspection, the signature of the person who performed the inspection and the serial number,
or other identifier, of the hook inspected.
•
Hoist chains, including end connections, for excessive wear, twist, distorted links interfering with proper function,
or stretch beyond manufacturer's recommendations. Visual inspection daily; monthly inspection with a certification
record which includes the date of inspection, the signature of the person who performed the inspection and an
identifier of the chain which was inspected.
•
All functional operating mechanisms for excessive wear of components.
•
Rope reeving for noncompliance with manufacturer's recommendation.
1910.179(j)(3) Periodic Inspection
Complete inspections of the crane shall be performed at intervals as generally defined above, depending upon its
activity, severity of service, and environment, or as specifically indicated below. These inspections shall include the
requirements of the frequent inspection stated above and in addition, the following items. All deficiencies such as
listed shall be carefully examined and determination made as to whether they constitute a safety hazard:
•
Deformed, cracked, or corroded members.
•
Loose bolts or fasteners.
•
Cracked or worn hoist.
•
Worn, cracked or distorted parts such as pins, bearings, shafts, gears, rollers, locking and clamping devices.
•
Load, wind, and other indicators over their full range, for any significant inaccuracies.
•
Gasoline, diesel, electric, or other powerplants for improper performance or noncompliance with applicable safety
requirements. (IF APPLICABLE)
•
Excessive wear of chain drive sprockets and excessive chain stretch.
