|
On 2024-04-22 around 3:30 pm it was discovered that the crane's main hoist was in a faulted state. The operator (Adam Newsome) experienced the fault
after performing a safety reset and attempting to lower the hoist. There were no visible signs of any issues, mechanically. This fault had not been previously
reported by any other crane operators. The crane was previously unused, sitting idle. Note: the auxiliary hoists appeared to function normally. |

The spacer flanges were installed on both turntables today.
See photos and information in the following DocuShare Collection: Collection-39816
Important note: the fitment was quite tight due to interference with universal joints and grease nipples. The flanges were still able to be installed |

Thursday, November 28, 2024, 09:04, Adam Newsome, Hot Cell 1, Repair, Hot Cell turntables not rotating, access hatch not moving
|
It was reported that the hot cell turntables would not rotate and the access hatch could not be operated. The turntables' elevation motion was working
normally, and other cell functions were working.
Upon investigation, after going online with the PLC and checking the interlocks for the turntable, it was determined that motion was being prevented |

Friday, November 29, 2024, 15:23, Adam Newsome, Hot Cell 1, Maintenance, 1000 kg crane: y axis position display not functioning
|
After a recent power cycle, the y-axis referencing was lost for the 1000 kg crane. The position readout was also incorrect, somewhere on the order of
> 30,000 mm. On 2024-11-29, A. Newsome re-referenced the y-axis. The position readout correctly reset to zero, and both +y and -y motion is functioning
correctly, but the y-axis position readout on the HMI constantly displays 0 and does not change. To be investigated. |
