service is divided into two general classifications based upon the
intervals at which 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.
• 1910.179(j)(1)(ii)(b) - Periodic inspection - 1 to 12-month
intervals.
1910.179(j)(2) - Frequent Inspection
The following items shall be inspected for defects at intervals as
defined in paragraph (j)(1)(ii) of this section 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:
• 1910.179(j)(2)(i) - All functional operating mechanisms for
maladjustment interfering with proper operation. Daily.
• 1910.179(j)(2)(ii) - Deterioration or leakage in lines, tanks,
valves, drain pumps, and other parts of air or hydraulic systems.
Daily.
• 1910.179(j)(2)(iii) - 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. For hooks with cracks or having
more than 15 percent in excess of normal throat opening or
more than 10° twist from the plane of the unbent hook refer to
paragraph (l)(3)(iii)(a) of this section.
• 1910.179(j)(2)(iv) - Hoist chains, including end connections,
for excessive wear, twist, distorted links interfering with proper
function, or stretch beyond manufacturer's recommendations.

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.
• 1910.179(j)(3)(v) - Excessive wear on brake system parts,
linings, pawls, and ratchets.
• 1910.179(j)(3)(vi) - Load, wind, and other indicators over their
full range, for any significant inaccuracies.
• 1910.179(j)(3)(vii) - Gasoline, diesel, electric, or other
powerplants for improper performance or noncompliance with
applicable safety requirements.
• 1910.179(j)(3)(viii) - Excessive wear of chain drive sprockets

1910.179(j)(3) - Periodic Inspection
Complete inspections of the crane shall be performed at intervals
as generally defined in paragraph (j)(1)(ii)(b) of this section,
depending upon its activity, severity of service, and environment, or
as specifically indicated below. These inspections shall include the
requirements of paragraph (j)(2) of this section and in addition, the
following items. Any deficiencies such as listed shall be carefully
examined and determination made as to whether they constitute a
safety hazard:
• 1910.179(j)(3)(i) - Deformed, cracked, or corroded members.
• 1910.179(j)(3)(ii) - Loose bolts or rivets.
