 Monday, January 25, 2016, 13:20, Allon Messenberg, T-Hall Crane, Maintenance, Possible oil leak 
|
Two small (approx. 5 cm across) puddles of green fluid were discovered on the floor, directly below the crane trolley. The hook block was lowered
and inspected. No fluid found on hook block.
The plant group (Neil Wong) was notified and asked to schedule an inspection when the maintenance crew is on site to inspect the ISAC target hall |

On Tuesday, February 14th I finished modifying Jason's boxes for the remote crane tests by adding shelves to mount cameras... Apart from given the edges
a quick sanding (so no one gets slivers)...which I will try and do tomorrow. |

|
On March 29, 2017, a 9 tonne steel shield block was transferred from the ARIEL Target Pit and placed into a
wood container on the Target Hall B1 level with the overhead crane main hoist in Local Mode without incident.
Afterwards, the overhead crane was switched into Test Mode (which is the same as Remote Mode but without the

|
On March 29, 2017, a 9 tonne load was transferred in the ARIEL Target Hall with the overhead crane (TRIUMF crane #44). On April 3, 2017, several drops of
green oil were observed on the floor and hookblock directly beneath the single equalizing sheave. The Remote Handling department millwrights were notified
and an inspection of the crane using a man-lift was performed to verify the source of the oil leak. Upon inspection, it was confirmed that the green oil |

Tuesday, April 18, 2017, 19:28, Jason Kapalka, T-Hall Crane, Development, ATH overhead crane fault investigation 8x
|
On April 18, 2017, an investigation was initiated to determine the cause of the ARIEL Target Hall overhead crane faults that occurred while attempting to
perform remote lifting operations in Test Mode on a 8.6 tonne SEG block (see E-Log #30). Hugo Lapointe (Automation Technician, REEL-COH) requested pictures
of the HIM (Human Interface Module) displays, located inside the electrical panels in the crane control room, immediately after a fault to assist with |

Tuesday, May 16, 2017, 17:30, Jason Kapalka, T-Hall Crane, Development, ARIEL Target Hall Overhead Crane Measurements
|
On May 5, 2017 the Beamlines and Remote Handling groups recorded distances in the ARIEL Target Hall from the Target Pit floor and B1 Target Hall floor elevations
up to the overhead crane girders and main hoist rotation plate using a laser measurement device (see attached file).
On May 19, 2017, the Beamlines
Group measured the B1 and Target Pit floor elevations relative to the Cyclotron centre (see attached file). |

Powered down ARIEL Target Hall Crane today by switching off main power switch on B1 level in preparation for site-wide BC Hydro power outage on
Dec. 27-29. |

|
Background: On 2019-06-25 a Pri VelFdbk Loss fault was discovered on the Main Hoist East Drum South Motor of the ARIEL Target Hall Crane. The crane was
used previously on 2018-08-22 without incident. The main hoist of the crane was unavailable until the Hugo Lapointe (Automation Technician) from the crane
manufacturer (REEL-COH) replaced the Allen-Bradley 20-750-ENC-1 Incremental Encoder board in the 800VFD with a new one, and replaced the Motrona cross |

Tuesday, November 19, 2019, 10:31, Adam Newsome, T-Hall Crane, Repair, 900VFD Encoder Board Replacement
|
An issue arose in which the ARIEL crane hoist could not be moved. It was determined that the East and West drums were out of synchronization (by more than
0.2 m, which the limit) and the encoder board inside the 900VFD had failed.

Thursday, February 13, 2020, 08:51, Adam Newsome, T-Hall Crane, Standard Operation, Remote mode door limit switch bypass
|
The non-existent safety limit switch for the target hall door which prevents remote motion has been bypassed in the crane PLC control panel to allow
for remote operation of the crane. This will be un-bypassed when a switch is installed. Specifically, a jumper was placed from terminal 18001 to 20121
and 20141 which will enable the hall lock safety relays 2012SR and 2014SR. The crane is currently operational in both local and remote mode. |

Friday, July 03, 2020, 15:43, Adam Newsome, T-Hall Crane, Repair, North Aux Hoist: West Travel Motion Failure
|
An issue was observed in which the North Aux hoist failed to travel West when commanded to, but the East motion was functioning. The North Aux hoist
Trolley was stuck in a position up against the East wall.
Present during troubleshooting: Adam N, Maico D, Tom K, Allon M, Travis C |

Wednesday, September 09, 2020, 10:51, Adam Newsome, T-Hall Crane, Repair, North Aux Hoist Replacement (followup on E-Log 44)
|
See E-Log 44 for details on North Aux Hoist failure.
A replacement VFD was ordered by Adam Newsome and installed by Tom Kauss.
Adam and Tom replaced the VFD in the South Aux hoist (which had been relocated to the North Aux hoist). The original braking resistor was used. |

Wednesday, September 15, 2021, 15:10, Adam Newsome, T-Hall Crane, Maintenance, Hoist Broken Fault (actually: cable wrap issue)
|
A fault occurred which presented as "114. Main Hoist Cable Broken (3200PX)". This occurred when a SEG block was suspended approximately 1 m
off the ground.
Upon inspection, it was determined that the cable was in fact not broken, but wrapped around itself. There are no guides, and it is possible for |

Thursday, September 16, 2021, 09:37, Adam Newsome, T-Hall Crane, Maintenance, Bridge Encoder Homing
|
The bridge motion was slowed due to encoder homing issue. It is likely that the problem which occurred yesterday caused an velocity fault (mismatch between
encoder speed and commanded speed), which unlatches the homing status for the bridge motion axis.
When the bridge was in the southmost position (bumper pressed against wall), the position readback was: 0.353 m, encoder count = 5164003. |

Tuesday, November 23, 2021, 11:01, Adam Newsome, T-Hall Crane, Repair, Load Cell - Not Functioning
|
The load cell which is located on the crane itself to display the load to operators was reported not working during the week of November 15. It is planned
to investigate on Nov. 25 and this e-log will be updated with the status.

Thursday, January 06, 2022, 10:46, Adam Newsome, T-Hall Crane, Development, Modification of South Limits
|
Edit: as of May 30, 2022, the modification has been reversed, and the crane is functioning normally as per the manufacturer's limits.
Modifications have been made to the crane to allow for the South Aux Hoist to reach closer to the South wall during the ARIEL Hot Cell installation |

Tuesday, February 01, 2022, 08:29, Adam Newsome, T-Hall Crane, Repair, North Aux Hoist - West Motion Failure
|
An issue was observed in which the North Aux hoist failed to travel West when commanded to, but the East motion was functioning. The up/down motion
was also functioning. The North Aux Hoist Trolley failed during regular usage, seemingly randomly, when it was about 70% towards the West end of travel.
Note that the West motion VFD inside the North Aux Hoist is the one previously taken from the South Aux Hoist (the same issue with the North Aux Hoist |

Friday, February 18, 2022, 09:26, Adam Newsome, T-Hall Crane, Maintenance, Potential grease leak observed
|
Naimat Khan noticed after using the crane that some grease dropped onto a spreader bar, and believes it is a leak from the main hoist (see attached photo).
The hoist should be inspected.

Tuesday, March 15, 2022, 10:03, Adam Newsome, T-Hall Crane, Repair, North Aux Hoist VFD Replaced
|
The North Aux Hoist VFD which had failed (e-log 50) was replaced today by Tom Kauss and Adam Newsome on Work Permit A2022-03-15-1.
The hoist's motions were all tested - it is functioning normally again. |
