INSPECTION REQUIREMENTS

REFERENCE ASME B30.5a AND OSHA 1910.180

INSPECTION CLASSIFICATION

1. Initial inspection.

Prior to initial use, all new, altered, modified or extensively repaired cranes shall be inspected by a designated person to insure compliance with provisions of this standard.

2. Regular inspection.

Inspection procedure for cranes in regular 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 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.

  • A.

    Frequent inspection - daily or before each use

  • B.

    Periodic inspection - one to twelve-month intervals or as specifically recommended by the manufacturer or qualified person.

DESIGNATED PERSONNEL SHALL PERFORM INSPECTIONS ONLY.

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.

FOR COMPLETE INSPECTION REQUIREMENTS

  • 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. Refer to ANSI/ASME B30.10.

  • 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.

    • D.

      Use care when inspecting sections of rapid deterioration around flange points, crossover points, and repetitive pickup points on drums.

    • E.

      Inspect number, distribution, and type of visible broken wires. Reference Rope Maintenance section in the owner’s manual.

Continued use of rope depends upon good judgment by a designated person in evaluating remaining strength in a used rope after allowance for deterioration disclosed by inspection. Continued rope operation depends upon this remaining strength.
