5005EH OWNERS MANUAL

INSPECTIONREQUIREMENTSPERIODIC INSPECTIONAny deficiencies, such as those listed below, shall becarefully examined and determination made as towhether they constitute a hazard:1. Inspect for deformed, cracked or corrodedmembers in the crane structure and entire boom.2. Inspect for loose bolts, particularly mounting bolts.3. Inspect for cracked or worn sheaves and drums.4. Inspect for worn, cracked, or distorted parts suchas pins, bearings, shafts, gears, rollers anddevices.5. Inspect for excessive wear on brake and clutchsystem parts and lining.6. Inspect crane hooks for cracks.7. Inspect travel steering, braking, and locking devicesfor malfunction.8. Inspect for excessively worn or damaged tires.9. Inspect hydraulic hose, fittings, and tubing for thefollowing problems:A. Evidence of leakage at the surface of theflexible hose or its junction with metal andcoupling.B. Blistering, or abnormal deformation to the outercovering of the hydraulic or pneumatic hose.C. Leakage at threaded or clamped joints thatcannot be eliminated by normal tightening orrecommended procedures.D. Evidence of excessive abrasion or scrubbingon the outer surface of a hose, rigid tube, orfitting. Means shall be taken to eliminate theinterference of elements in contact or otherwiseprotect the components.10. Inspect hydraulic pumps and motors for thefollowing problems:A. Loose bolts and fasteners.B. Leaks at joints between sections.C. Shaft seal leaks.D. Unusual noises or vibrations.E. Loss of operating speed.F. Excessive heating of the fluid.G. Loss of pressure.11. Inspect hydraulic valves for the following problems:A. Cracks in valve housing.B. Improper return of spool to neutral position.C. Leaks at spools or joints.D. Sticking spools.E. Failure of relief valves to attain or maintaincorrect pressure setting.F. Relief valve pressure shall be checked asspecified by the manufacturers.12. Inspect hydraulic cylinders for the followingproblems:A. Drifting caused by fluid leaking across piston.B. Rod seals leaking.C. Leaks at welding joints.D. Scored, nicked, or dented cylinder rods.E. Damaged case (barrel).F. Loose or deformed rod eyes or connecting joints.13. Inspect hydraulic filters for evidence of rubberparticles on the filter elements indicating possiblehose, “O” ring, or other rubber componentdeterioration. Metal chips or pieces on the filtermay denote failure in pumps, motors, or cylinders.Further inspection will be necessary to determinethe origin of the problem before corrective actioncan be taken.14. Inspect labels to confirm correct location andlegibility. Reference decal layout in this manual forproper location of decals.15. Rope Inspections need not be at equal calendarintervals and should be more frequent as therope approaches the end of useful life. Aqualified person shall inspect the wire rope basedon such factors as:A. Expected rope life as determined by experienceon the particular installation or similarinstallations.B. Severity of environment.C. Percentage of capacity lifts.D. Frequency rates of operation.E. Exposure to shock loads.This inspection shall cover the entire length of therope. Only the surface wires need to be inspectedand no attempt should be made to open the rope.Any deterioration resulting in appreciable loss oforiginal strength shall be noted and determinationmade as to whether use of the rope would constitutea hazard. A few notable deterioration points are listedbelow:3-2.08/16/05
