“Overhead and Gantry Cranes.”, all gantry cranes should have an:
1910.179(j)(1)(i) 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.
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 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 deformations 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 connection, 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 reeling 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 power plants for improper performance or noncompliance with
applicable safety requirements. (IF APPLICABLE)
• Excessive wear of chain drive sprockets and excessive chain stretch.
