Specialty Crane Inspections Kor-Pak Offers:
End of Life Crane Inspections
- These are an extensive electrical and mechanical analysis of all components to determine crane life
left for service. - Motors are tested for FLA, winding resistivity, brush and brush gear conditions, commutator and slip ring conditions supported with digital photographs.
- All contactors are tested for squareness and parallelism along with contact tip wear, coil condition determined with a VOM and supported by digital photography.
- Gear Cases are dismantled, end play inspected with a digital dial indicator and bearings inspected for overall mechanical condition, gears NDT with Liquid Die Penetrant for sub-surface failure potential again supported by digital photography. Lubricant form the gear case will be sent to a laboratory for analysis of content to determine other mechanical failure potentials.
- The crane structure will have a 100% visual inspection of all welds, connections, and attachment points
sounded for security with a hammer. - The End of Life Inspection will be 100% documented listing all deficiencies and safety violations will be furnished along with copies of all photographs taken during the inspection.
Critical Crane Component Inspections
- Is usually conducted after a gross overload situation, an acute shock load, or a Two Block incident.
- Critical Component Inspections require that the structure is 100% inspected, camber measured on both girders both loaded and unloaded to record the difference. 100% visual inspection of all welds, connection points and affected components.
- Gear Cases get a 100% tear down, visual inspection, and an NDT using the liquid die penetrant or magnetic particle inspection all procedures photographed for reference with the report.
- In a Two Block situation the drum will be 100% NDT and the procedure photographed for
