CERTIFICATE OF UNIT TEST AND/OR EXAMINATION OF
CRANES AND DERRICKS USED FOR LIFTING SERVICE



The examination shall be carried out in conjunction with each unit proof load test. The qualified person, or his authorized representative, shall make a determination as to requirements for the correction of deficiencies found. The examination shall cover the following points as applicable:

1. All functional operating mechanisms for improper function, maladjustment, and excessive component wear, with particular attention to sheaves, pins, and drums. This shall include operation with partial load, in which all functions and movements, including, where applicable, maximum possible rotation in both directions, are performed.

2. All safety devices for malfunction.

3. Deterioration or leakage in lines, tanks, valves, drains, pumps, and other parts of air or hydraulic systems.

4. Loose gear components (i.e., hooks, etc.), including wire rope and wire rope terminals and connections, with particular attention to sections of wire rope exposed to abnormal wear and sections not normally exposed for examination. Cracked or deformed hooks shall be discarded.

5. Rope reeving for compliance with certifying agent's recommendations.

6. Deformed, cracked, or excessively corroded members in crane structure and boom.

7. Loose bolts, rivets, or other connections.

8. Worn, cracked, or distorted parts affecting safe operation.

9. Excessive wear on and free operation of brake and clutch system parts, linings, pawls, and ratchets.

10. Load, boom angle, or other indicators shall be checked for any significant inaccuracy.

11. It shall be ascertained that there is a durable rating chart visible to the operator, covering the complete range of the certified agent's capacity ratings at all operating radii, for all permissible boom lengths and jib lengths, with alternate ratings for optional equipment affecting such ratings. Necessary precautions or warnings shall be included and operating controls marked or an explanation of controls shall be posted at the operator's position to indicate function.

12. Careful examination of the junction areas of removable boom sections, particularly for proper seating, cracks, deformities, or other defects in securing bolts and in the vicinity of such bolts.

13. It shall be ascertained that no counterweights in excess of the certified agent's specifications are fitted.

14. Such other examinations deemed necessary under the circumstances.
