Inspection Requirements
Reference ASME B30.5 and OSHA 1910.180 for complete inspection
requirements.
All inspections shall be performed by designated personnel only.
Inspection Classification
1. Initial Inspection
A.
Prior to initial use, all new, altered, modified, or extensively repaired cranes shall be inspected by a
designated person to ensure compliance with provisions of this standard.
2. Regular Inspection
3.
Inspection procedures for cranes in regular service are divided into two general classifications
based upon the intervals at which the inspection should be performed. The intervals, in turn, are
dependent upon the nature of the components of the crane and the degree of their exposure to wear,
deterioration, or malfunction. The two general classification are herein designated as “frequent” and
“periodic” with respective intervals as defined below:
i. Frequent Inspection – daily or before each use.
ii.
Periodic Inspection – one to twelve-month intervals or as specifically recommended by the
manufacturer or qualified person.
Frequent Inspection
Inspections should also occur during operation for any deficiencies that might appear between regular
inspections. Any deficiencies, such as those listed below, shall be carefully examined and a determination
made as to whether they constitute a hazard:
1. Inspect control mechanisms for maladjustment that interferes with proper operation.
2. Inspect control mechanisms for excessive wear of components and contamination by lubricants or
other foreign matter.
3. Inspect safety devices for malfunction.
4.
Visually inspect all hydraulic hoses, particularly those that flex in normal operation of crane functions.
5. Inspect hooks and latches for deformation, chemical damage, cracks, and wear.
6. Inspect for proper rope reeving.
7. Inspect electrical wiring and components for malfunctioning, signs of excessive deterioration, dirt and
moisture accumulation.
8. Inspect hydraulic system for proper oil level and leaks.
9.
Inspect tires for recommended inflation pressure, cuts, and loose wheel nuts.
10. Inspect connecting pins and locking device for wear damage and loose retaining bolts.
11. Inspect rope for gross damage, such as listed below, which may be an immediate hazard.
A. Distortion such as kinking, crushing, un-stranding, birdcaging, main strand displacement, or core
protrusion. Loss of rope diameter in a short length or unevenness of outer strands should be
replaced.
B. General corrosion.
C. Broken or cut strands.
