7.4.1 Replace all defective grease fittings. Clear and grease all crane gear components. For items to be disassembled and inspected, grease passages shall be flushed with solvent and proven free flowing prior to reassembly.

7.4.2 All winch cables for cranes shall be pressure slushed at the completion of all tests and inspections, use grease Mobilarma 798 (CFM).

7.4.3 Accomplish the requirements for ABS annual survey of cranes per reference ABS Guide for Certification of Lifting Gear, Chapter 2, Section 7. The Annual Survey includes the following:

7.4.3.1 Visual inspection of the crane structure for deformation, excessive wear, corrosion, damage or fractures, as necessary. The boom is to be lowered for this examination.

7.4.3.2 Visual examination of crane hooks for deformation, excessive wear or fractures.

7.4.3.3 Conduct a full operational test using normal and emergency launch/lowering and recovery procedures and controls. Conduct a visual external examination of crane machinery including prime mover, clutches, brakes, hoisting, slewing, luffing machinery.

7.4.3.4 Visual inspection of wire rope including end attachments.

NOTE: The Wire rope is not to be used if in any length of ten diameters: 1) The total number of visible broken wires exceeds 5 percent of the total number of wires, 2) If there is more than one broken wire immediately adjacent to an end fitting, 3) If the broken wires are concentrated in one area or one strand, or 4) If the rope shows signs of excessive wear, corrosion, flattening, kinks, separation of the strands or wires, core failures or other defect which renders it unfit for use.

7.4.3.5 The slewing ring assembly, where applicable, is to be examined for slack bolts, damaged bearings and deformation or fractured weldments. Rocking Tests, in accordance with the bearing manufacturer’s instructions, are to be taken and recorded for review by the attending surveyor at each annual survey.
