F. Loose or deformed rod eyes or connecting joints.
13.
Inspect hydraulic filters for evidence of rubber particles on the filter elements indicating possible hose,
O-ring, or other rubber component deterioration. Metal chips or pieces on the filter may denote failure
in pumps, motors, or cylinders. Further inspection will be necessary to determine the origin of the
problem before corrective action can be taken.
14.
Inspect labels to confirm correct location and legibility. Reference decals layout in this manual for
proper location of decals.
15. Rope inspections need not be at equal calendar intervals and should be more frequent as the rope
approaches the end of useful life. A qualified person shall inspect the wire rope based on such factors
as:
A. Expected rope life as determined by experience on the particular installation or similar installations.
B. Severity of environment.
C. Percentage of capacity lifts.
D. Frequency rates of operation.
E. Exposure to shock loads.
i. This inspection shall cover the entire length of the rope. Only the surface wires need to be
inspected and no attempt should be made to open the rope. Any deterioration resulting in
appreciable loss of original strength shall be noted and determination made as to whether use
of the rope would constitute a hazard. A few notable deterioration points are listed below:
1. Reduction of rope diameter below nominal diameter due to loss of core support.
2. Internal or external corrosion.
3. Wear of outside wires.
4. Severely corroded, cracked, bent, worn, or improperly applied connections.
Cranes Not In Regular Use
A crane, which has been idle for a period of more than one month or more, shall be given an inspection
conforming to the “initial” and “periodic” inspection requirements of this section.
Inspection Records
Dated records of periodic inspection should be made on critical items such as brakes, crane hooks, rope,
cylinders, and relief pressure valves.
Testing Requirements
Reference ASME B30.5 and OSHA 1910.180 for complete testing
requirements.
All testing shall be performed by designated personnel only. 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.
1. Test all functions to verify speed and operation.
2. Ensure all safety devices are working properly.
3.
Confirm operating controls comply with appropriate function labels.
4. Test loads shall not exceed 110% of the manufacturer’s load rating.
5.
Written reports shall be maintained showing test procedures and confirming the adequacy of repairs.
