  • Visual Crane Inspections
  • Check collectors and shoes for wear.
  • Visually check insulators for cracks.
  • Inspect all lighting fixtures, on the crane to insure all are illuminated and that the lighting in the cab, and that all electrical outlets (receptacles) are functional and grounded.
  • Inspect all the flat festoon cables for degradation and or damage. Insure cables are being properly supported and there is proper clearance between the structure and the cables so the do not make any contact to wear or rub the jacket.

  • Visual Crane Inspections
  • Inspect the control cab conduit for proper installation and are properly supported, outlet receptacles are functional, status lights and all crane rail lights to insure they illuminate are in a working condition.
  • Worker Verification: In Panels 4, 3, 2, & 1, ensure all fuses are the correct size, for the various components, and there are no signs of damage or degradation to the fuse blocks.
  • Inspect the Cranes safety Horn wiring , switches and contacts on the control panel in the cab for degradation.

  • PLC Battery Replacement:
  • Replace the back-up battery (s) in SLC Processor (S).
  • Catalog Number 1747-BA, Every Re-fuel cycle.
  • Note: Processors have a capacitor that provides at least 30 minutes of battery back-up while the battery is disconnected. Data in RAM is not lost if the battery is replaced within 30 minutes.
