|
Noticed oil leaking out of reduction box, scan and swipe, disconnect e motor and all related cables from bridge, remove motor and reduction box assembly
with over head crane, disassemble reduction box, grease broken down and separated likely cause of leak. Inspect bearings and internals for wear -all good
re assemble with new grease and gaskets (we added two grease nipples to the bearing housing to aid lubrication), test e motor on its own- good. |

Thursday, October 31, 2019, 14:31, Adam Newsome, Service Bridge, Repair, Outrigger 2 Vertical Drive Repair
|
Outrigger 2 vertical drive repair is complete - ball screws were replaced to resolve a jamming issue (this work was done in the summer).
The outrigger has been recalibrated and all limit switches and feedback signals tested. All ranges of motion were tested multiple times as well.

|
The following items from Phase 1 of 2 of Bridge Lift Mechanism Refurbishment (O504) are complete:
Replacement of pneumatic tubing
Replacement of hydraulic cylinders for lifting, and procurement of spare
The
newly refurbished system has been tested by Dan McDonald (June 16, 2021) and verified as functioning. |

|
The Hinged section of the festoon rail at Cyclotron has a piston to keep rail in the up position for shutdown work (Bridge and Trolley in tank work).
A plastic liner for the piston has fallen apart and needs to be replace.
A spare one has been temporarily put into place until another one has been machined and reinstalled. |

Tuesday, March 28, 2023, 12:02, Nadia Jorgenson, Service Bridge, Repair, Outrigger 1 Failure and Repair
|
During the 2023 shutdown outrigger 1 failed. While performing the HE Probe removal we found
that the outrigger could only travel vertically about one inch in each direction. |

Thursday, September 07, 2023, 13:21, Jason Zhang, Service Bridge, Development, Outrigger #1 and #2 individual testing complete
|
Outrigger #1 and #2 have had their controls system overhauled as part of the O503 project. The previous controls enclosure and the elements have been
replaced with a new aluminum enclosure which contains DIN rail relays, a 5V power supply, and a +-12V Power supply. The new centrepost slave PLC unit handles
the control logic of OR1, OR2, the Bridge and is connected to the main PLC in the control room through Ethernet. Both outriggers were tested individually. |

Wednesday, October 18, 2023, 12:35, Jason Zhang, Service Bridge, Development, O503 Bridge and Outrigger integration testing
|
Service bridge, Outrigger #1, and Outrigger #2 have had the controls system migrated to PLC controls. The 5069-AENTR control unit is located at
the centrepost and will be mounted there after wiring is cleaned up. Preliminary testing consisted of operators simulating a shutdown task was performed
today and was a success. Minor adjustments to the encoder logic will be made before the commissioning test. The follow tests were done: |

Tuesday, November 14, 2023, 12:13, Nadia Jorgenson, Service Bridge, Repair, First Festooning Car "H" channel replacement
|
Damaged "H" channel removed from the first festooning car, and spare channel was put in place.
Note: it seems like the aluminum channel is not strong enough for the forces its being put under, and is resulting in deformations (See picture
"Festooning car H channel deformation"). We suspect this has happened in the past, notches were cut out where the deformation likely occurred |

Tuesday, November 14, 2023, 12:38, Nadia Jorgenson, Service Bridge, Maintenance, Bridge Orbit Counter Work in 2023
|
All the bearings on both the upper and lower wheel were replace to see if it will improve
the accuracy of the orbital position reading. See drawing SK-2489 for list of bearings used.
The encoder was also replaced to match the style used elsewhere. |

Thursday, May 16, 2024, 12:33, Riley Sykes, Service Bridge, Maintenance, Center Post Bearing
|
| Center post bearing on service bridge inspected, turned freely by hand and regreased with Molub-Alloy 777-1 ES |
|
Friday, May 31, 2024, 11:28, Riley Sykes, Service Bridge, Maintenance, Outrigger mechanical inspection
|
Both outriggers were inspected and were found to be mechanically sound. No damage to components or hardware visible, will revisit with pre-inspection
before shutdown period 2025. |
|
Friday, June 14, 2024, 10:04, Riley Sykes, Service Bridge, Maintenance, Service/ Bridge inspection
|
Yearly, 2 Year and 5 Year service completed. All bearings on support frames turn freely and were regreased with Molub Alloy 777-1 ES. Reducer repacked
as well. Reinspect pre shutdown and lubricate orbital drive chain before wiping off excess. |

|
A simulated removal of the LE2 Probe from the Cyclotron tank was performed by the RH and Probes group using the
service bridge, upper resonator trolley, LE probe attachment, and the (soon to be) attached LE Probe removal
procedure on 2017-02-23. |
